Release list
Mnemosyne OS v1.4.4 — downloads are on v1.4.4-infinity
Mnemosyne OS — Infinity Edition v1.4.4 · The Whole Document
v1.4.4 · The Whole Document
- A long document now enters memory whole. It used to be cut at 18 000 characters.
- A model server you run yourself becomes a route, on your own network.
- The chat reads several vaults at once, follows your pick, or lets the model choose.
- Ask Mnemosyne about Mnemosyne: a manual ships inside the app, in FR, EN and ES.
- The capture browser is rebuilt for the web: a page as text, as a PDF or every image in one click, reviewed before it enters a vault.
- Report a problem from any window, and the app boots faster.
Mnemosyne OS — Infinity Edition v1.4.3 · What Your Agent Knows
Mnemosyne OS — Infinity v1.4.3 · What Your Agent Knows
Dev: if you run a coding agent beside your IDE, or use the MCP, install this one.
Point a vault at .claude or .cursor: those folders were watched and never read, in silence.
Also: desktops on the canvas, to-do lists that ring, notes in their own window.
Mnemosyne OS v1.4.3 — downloads are on v1.4.3-infinity
Downloads (Windows, macOS, Linux) are here: https://github.com/Mnemosyne-OS/Mnemosyne-Neural-OS/releases/tag/v1.4.3-infinity
This page exists because copies released before 1.4.3 build their "see the release" link without the -infinity suffix the tags carry. Rather than leave those clicks on a 404, this tag points at the real release. Installs from 1.4.3 onward link straight to it.
Mnemosyne OS — Infinity Edition v1.4.2 · The Clean Cut
Mnemosyne OS — Infinity v1.4.2 · The Clean Cut
Cut a subject out of any image. A new room for making pictures, and GPU image memory.
Mnemosyne OS — Infinity Edition v1.4.1 · The Closed Pipe
Mnemosyne OS — Infinity Edition v1.4.1 · The Closed Pipe
Linux hotfix. v1.4.0 shipped a Linux build that could become unusable on first launch. This release fixes it.
Windows and macOS are unchanged from v1.4.0. Their installers are carried over untouched, so their users are not asked to re-install.
Mnemosyne OS — Infinity Edition v1.4.0 · The Infinite Vision
Mnemosyne remembered everything you wrote — and nothing you photographed. That changes today.
343 commits since v1.3.8. One theme: sight.
🖼️ Theia — your memory learns to see
A new image engine — Theia, named for the Titaness of sight, sister of Mnemosyne — gives every vault an eye.
- Images in your watched folders are embedded locally (SigLIP 2, running on your machine — no cloud, no API, no account).
- Ask in chat: "show me the pieces that look like a blue cup" — the matching photos appear as thumbnails under the answer, in any of the app's languages.
- Color words are honored by a pixel-level palette channel; recurring subjects are named automatically as emergent categories.
- Three recall channels — semantic, color, category — fused by rank. Every lever was measured on a frozen internal benchmark before shipping; levers that did not pay were removed.
- Honest by construction: a cold or still-indexing engine says so instead of claiming "no matches", and the model may never pretend it saw pixels it did not receive.
Off by default. One Settings toggle installs the engine, downloads the pinned weights, and indexes your vaults. When off, nothing changes — byte for byte.
🗂️ The gallery — your images, one place, alive
- Every image your vaults hold, grouped by day — a photo you add appears live, without reopening.
- Filter by vault, star rating, pinned, or the categories the engine discovered.
- The human always outranks the model: rate, pin, describe, correct a category, teach a new one, rename or merge — the automatic pass never overwrites what you asserted.
- Full in-app viewer: cursor-centric zoom, drag-to-pan, filmstrip.
- Adding a whole image folder is one gesture: pick the folder, name the vault, done.
🌌 The canvas unlocks — an endless plane
- Pan by dragging the void, zoom from 10 % to full detail (Ctrl + wheel anywhere), double-click empty space to travel, one control to frame everything.
- Decorate the plane: analog world clocks, weather, photo frames, and stickers — a built-in animated library, plus libraries you make from any folder.
- Every ornament has real hands: resize, rotate, tint, freeze, straighten.
- The menu rail docks to any edge — left, right, top or bottom.
📥 Images flow straight into memory
- Paste or drop an image anywhere on the canvas: a picker asks which vault receives it — with a standing choice if you always answer the same, and a "+ new vault" path.
- A capture browser (beta) opens the web in a clean, sandboxed window — your search engine, your favorites — and captures a page's images into the vault you chose.
- In chat, a pasted or dropped image becomes a thumbnail the model actually sees.
- Every capture is one human gesture — nothing is captured automatically.
🧠 Local models work in the installed app — fixed
On a fresh install, every local model failed with callback is required: the packaged app resolved a transitive dependency to the wrong major version. Fixed, and the build now carries a strict gate that fails if any version conflict survives packaging. Reported by a beta tester — thank you.
📝 Notes grows up
A constellation view (deep-space map of the corpus), a kanban that shows every spine's truth, a corpus mind map, highlights in five colours with remarks you can read back and search, read-aloud in the language the note is written in, linked folders watched to the bottom.
🔊 Reading aloud stops gasping
Read-aloud builds a lead and prepares ahead — gapless playback even on slow local engines. One engine per surface (conversation / read-aloud / long reading), an expressivity control, a new local engine (Chatterbox). MnemoReader 1.1.0 prepares chapters ahead and speaks seven languages. Agents can render a script to a WAV through the SDK — behind the first sensitive permission scope, never auto-granted; an unknown voice clone is refused, never substituted.
Under the hood
core-engine 1.2.0 (per-kind image derivative versions, FK cascade, visible embedding debt instead of silent drops) · the TTS sidecar no longer eats boot RAM · ghost image derivatives can no longer score · vault creation asks what should feed it and the new vault is usable immediately · dozens of canvas/widget fixes (modals always in view, z-order never walks backwards).
Install & verify
- Windows builds are code-signed (Certum OV certificate, RFC-3161 timestamped) and auto-update once installed.
- macOS (Apple Silicon) and Linux (AppImage / deb) builds are unsigned; on macOS, right-click → Open on first launch.
- Your data never leaves your machine. No account. No telemetry.

Mnemosyne OS — Infinity Edition v1.3.8 · The Second Channel
What's new
🔎 Your memory now finds the exact word, not just the idea
A question that hinges on a rare literal token — a proper noun, an identifier, a number — could miss the session that contains it: dense embeddings map unique strings close to noise. Retrieval now runs a second, independent channel: your vault is also ranked by exact words (Okapi BM25 over a persistent inverted index, built locally inside the vault database), and the two rankings are merged by rank. Everything stays on your machine — no API, no index service, and hybrid search is ON by default (MNEMO_LEXICAL_FUSION=0 restores the previous behaviour exactly).
Measured on LongMemEval full-haystack with a strict judge: 29 → 37 of 48 questions correct, reproduced across two independent runs — and confirmed on 48 held-out questions never seen during development, with more evidence retrieved and zero regressions. Fusion parameters are literature defaults, deliberately untuned.
🚪 What one app writes, another still cannot read — on every channel
Per-app memory isolation is now enforced inside the retrieval channel itself, not at its call sites — the new lexical channel provably obeys the same ownership rule as the vector channel (5 dedicated tests).
🗂️ A count with an imprecise date says so
Asked "how many X in the last month?", the assistant no longer silently drops an item recorded as just "April 2023". It counts it and tells you the date is imprecise — excluding only what is demonstrably outside the window. The arbitration is yours, not the machine's.
🧠 Local models answer instead of thinking forever
A reasoning model could deliberate past its own reply and deliver nothing. Thinking is now bounded relative to the answer budget: on a 2B reasoning model, 7 empty answers out of 24 runs before, 0 out of 24 after — strongest on modest machines.
🔒 The model's private reasoning stays out of your memory
Streaming a reasoning model's thoughts (so the chat can fold them) no longer lets them reach the internal consumers of the model's return value — capability parsing, vault writes, dream ledgers.
🪟 An auto-opened widget no longer covers the one you opened
Widgets the app opens on its own now stack below the one you are actively using.
Under the hood
The installer now presents the product EULA in English, French and Spanish, and offers to launch Mnemosyne OS when the install finishes. Windows binaries are code-signed (Certum OV certificate, RFC-3161 timestamped), verified on both the Setup and the Portable. A new build gate refuses to sign a package that cannot be imported — the failure class that shipped once can no longer pass. The core also gained exact identity resolution (typed outcomes instead of a lossy null — "we don't hold it" and "you may not read it" are different answers now) with a portable conformance suite.

Mnemosyne OS — Infinity Edition v1.3.7 · The Kept Promise
Mnemosyne OS — Infinity Edition v1.3.7 · The Kept Promise
Your memory, your machine. Mnemosyne OS is a sovereign, local-first memory
operating system: your documents, notes and conversations become a living,
searchable memory that never leaves your computer unless you say so.This release is about the models. The whole loop now runs on your machine
— model, memory and retrieval, with no key and no account. The local
catalogue is current again, with context windows sixty times larger than what
shipped before, and you can load your own. For those who do use the cloud,
providers finally hand you their real model list, and every call keeps a
journal priced the way you price it.
Highlights
🖥️ Fully local, end to end — and genuinely usable
You can now run Mnemosyne OS with no cloud at all: a local model answering
over locally-embedded memory, on your own hardware. No API key, no account, no
call leaving the machine. That was the point of the product from the start; as
of this version it is a working configuration rather than an aspiration.
Said plainly, because you deserve the trade-off and not a slogan: a small local
model recalls less well than a large cloud one. We measure this, and the
gap is real — deep multi-session recall in particular is where a cloud model
still wins. For everyday use — asking your own documents and notes, picking up
a thread, finding what you wrote — the local setup holds up. Start local; reach
for the cloud when a question needs it. Either way the memory stays yours.
🧩 A local catalogue that is current again — and yours to extend
The bundled models had aged between one and two and a half years. Worse, the
small model a modest machine picks first — Phi-3 Mini, 4 GB RAM — had a
4096-token context window, while memory-grounded answers inject far more
than that: the first real question overflowed it. The entry point was the one
guaranteed to disappoint.
Eight new entries, each verified live against the HuggingFace API, all with
a 262k-token context (131k for Gemma):
| Model | Size | Note |
|---|---|---|
| Qwen 3.5 0.8B / 2B | 532 MB · 1.3 GB | runs on very little |
| Qwen 3 4B Instruct 2507 | 2.5 GB | no thinking pass — straight answers |
| Qwen 3.5 4B / 9B | 2.7 · 5.7 GB | reasoning |
| Gemma 3 4B | 2.5 GB | a different architecture, on purpose |
| Qwen 2.5 Coder 3B / 7B | 1.9 · 4.7 GB | replaces CodeLlama |
Bring your own: point the app at any local .gguf and it appears in the
picker. Nothing was repointed or deleted — models you already downloaded keep
working, marked legacy and moved to the bottom of the list. And local is
now a choice, not a fallback: the picker stops hiding whichever list you are
not on.
🔑 Your provider hands you its own model list
Bring-your-own-key providers now answer the only question that matters: what
can this key actually reach? The list comes from the provider itself, so you
pick from real, current models instead of typing a name and hoping. The key
belongs to the provider rather than to a single model row, a bad key is called
a bad key even when the provider answers 400, and a missing bridge is no
longer reported as an unreachable provider.
💸 A journal of what every call costs — at your prices
Every call now leaves a local journal entry: which model, what it spent.
The app ships no price table — you enter the rates your provider charges
you, and nothing is invented on your behalf. The cost panel shows what the
gate actually debited, a wallet can read its own metered trail, and a
figure that cannot be known shows — rather than a convincing zero.
☁️ Mnemosyne Cloud, in two tiers
For those who would rather not manage keys at all, the sponsored cloud now
comes in two tiers, with the retrieval budget sized to the tier instead of
one setting for everyone.
🔒 Protection you choose, and routing that honours it
Vaults are created normal; you decide what to raise. Marking one
MAXIMUM now genuinely keeps its content off the cloud route — through
ingestion, through the dream layer, through fact extraction, and through the
three text-to-speech paths that could previously read a locally-guarded answer
aloud. The lock is visible before you commit to a conversation rather than
after, and a refused route is a decision you can see and override with “send
anyway”, never a silent wall.
🔄 Updates that tell you what they are
The update dialog now shows the release notes — what changes, before you
decide — instead of a bare Download. On macOS, where builds are not yet
signed and the app cannot update itself, the button opens the release page
instead of doing nothing.
Fixed
- Local models are billed as local: newly added models were loaded on your
machine and the question still went to the cloud. - The local model works for a whole session — every second message used to die
on “No sequences left”. - Prompts are budgeted against the context window the model actually got,
not the one advertised, including the first question of a session. - Reasoning models: their scratchpad is folded on screen and no longer leaks
elsewhere — and they no longer return an empty answer when a whole reply is
spent thinking. - Token estimates were measured on English and were wrong for two other
languages. - The assistant no longer invents a shared past with you.
- The chat pill names the model that actually runs, answers name their own
language, and web search says what is genuinely wrong instead of failing
quietly.

Mnemosyne OS — Infinity Edition v1.3.6 · The Persona
Mnemosyne OS — Infinity Edition v1.3.6 · The Persona
Your memory, your machine. Mnemosyne OS is a sovereign, local-first memory
operating system: your documents, notes and conversations become a living,
searchable memory that never leaves your computer unless you say so.This release is about the OS taking your shape: it speaks four new
languages, wears the colour you choose, gives its voice a face you pick —
and its assistant a character. Underneath, web search finally works, and
you can see exactly what everything costs your machine.
Highlights
🌍 Four new languages — Deutsch, Português, Русский, 中文
The shell now speaks seven languages: English, Français, Español, and — new,
in beta — German, Portuguese, Russian and Chinese. Every settings page,
every widget, every dialog. Cartridge content falls back to English while its
translations catch up, and the ★ Recommended embedding model follows your
language too, so retrieval quality follows the switch.
🔮 The orb gets a wardrobe — and a full-screen mode
The voice assistant's orb is no longer one face. Five abstract skins —
Aurora, Nebula, Plasma, Halo, Constellation — join the face family, each
tuned to its own geometry. And when you want the assistant to be the room,
a full-screen option lets the orb swallow the whole viewport.
🎨 The accent colour is yours
Pick your accent in Settings → Appearance and the whole shell follows —
chips, hovers, the brand mark, the close button, the title bar and canvas
(coloured directly, or derived from your accent). This runs deep: dozens of
places where the theme silently never arrived were rewired, and cartridges
now inherit the host's design tokens live — an installed app matches your
theme the moment you change it.
🎭 A character for the assistant — that never touches your memory
The chat quick rail gains a cognitive lens: sixteen archetypes that shape
how the assistant speaks — its tone, its angle, its manner. By design the lens
is a costume, not a filter: we measured what happens when personality is
allowed to steer memory retrieval, and it degrades factual recall — so the
costume stays a costume, and your memory stays exact. A companion voice for
text replies is on by default, and the soul settings take their real name:
Psyche.
🌐 Web search that actually works
Auto web mode reached the web again — its gate had quietly died. It is
rebuilt on model triage, so it works in any language, with your own trigger
words, a relevance guard that keeps on-topic results in other languages,
and SearXNG one click away. Pages are read as clean markdown, keeping the
passages that answer your question — and the chat can no longer cite a web
search that never ran.
📊 See what it costs the machine
System Diagnostics became a cost meter: a live chart of CPU, memory, GPU
and VRAM over the last four minutes, and Mnemosyne's own network usage,
split by destination — what the app puts on the wire, visible. The disk
tools can now reclaim space nothing could reach (22 GB on the machine we
measured), and a counter the machine can't read shows “—”, never an invented
zero.
🪙 Credit by card, license in the app
Buy cloud credit with a card — a themed confirmation names the wallet
being credited before anything is charged. The Engramm license is sold in
the app, free-credit and free-license requests are capped at one per wallet
per 24 h (and say when they can be asked again), and every sale lands in the
Founders Console.
🚪 A quit you can trust — and take back
Closing the app shows a measured estimate and a countdown you can
cancel; every shutdown step is now time-boxed. The freeze some of you hit on
quit lived exactly here.
🗣️ Voice installs, hardened
The multi-gigabyte voice-engine downloads are now resumable and owned by the
app: silent steps get a heartbeat, progress reads in MB against a GB total,
the license padlock is visible before you click, and measured runtime
budgets decide which engine your machine can actually run.
✨ Around the shell
One hairline switch everywhere, one header across all seventeen settings
pages, no native dropdown left in the panel. The About page breathes — the
animated infinity, and where to find us. MnemoHub opens one window per
cartridge, local cartridges stop waiting on the network, and the creator
door says plainly that publishing needs a license.
Fixed
- Chat: renaming or recolouring a conversation no longer reorders the history,
opening one no longer jumps it to the top, and the view no longer scrolls
away while a long answer is being read. - Language changes reach already-open windows immediately.
- The diagnostics disk scan no longer freezes the app.
- Cloud calls migrated off Gemini 2.5 ahead of its retirement, so nothing
breaks under you in October.
