Mnemosyne OS — Infinity Edition v1.3.5 · The Sealed Vault
Mnemosyne OS — Infinity Edition v1.3.5 · The Sealed Vault
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 custody. Your backup works again, your vaults can be
encrypted with a key only you hold, and ten gigabytes of machine-bound
toolchain stopped pretending to be part of your memory — the app moves them
out of your data folder on first launch, by itself.
Highlights
💾 A backup that actually completes
A backup used to sweep in everything the app had provisioned for you — the GPU
speech-to-text sidecar, the OCR engines, its own Python — so anyone who had used
those features ended up with an archive that failed outright. What goes into a
backup is now decided by an allow-list of what is genuinely yours (vaults,
settings, keys, cartridge data), and the size is announced before a single byte
is written. In practice: about 81 MB, where it used to attempt 5.5 GB.
If you are on 1.3.3, this is the reason to update.
🔐 Encryption at rest — armed only if you ask
Vault databases can now be encrypted with real AES-256 (SQLCipher), through
an explicit, human-gated flow that migrates the memory you already have. It is
off by default; nothing changes until you turn it on.
The key is random and sealed in your OS keystore, with a 24-word recovery
phrase as the way back. You can re-seal it for a new machine, or make a
machine forget it. If your memory has to travel, a passphrase can replace
the OS keystore entirely — changing it is journalled, so no crash can strand a
secret half-re-encrypted. And the app refuses to arm encryption it could not
carry off the machine, rather than locking you out of your own vaults later.
🗂️ Your files moved on disk — the big cleanup
Read this one even if you read nothing else. The first launch of 1.3.5 tidies
your data folder by itself. Everything the app had provisioned for this machine
leaves ~/.mnemosyne and goes where your operating system keeps large,
rebuildable data:
| Your system | Where they went |
|---|---|
| 🪟 Windows | %LOCALAPPDATA%\Mnemosyne OS |
| 🍎 macOS | ~/Library/Caches/Mnemosyne OS |
| 🐧 Linux | $XDG_CACHE_HOME/mnemosyne-os, or ~/.cache/mnemosyne-os |
What moved — seven folders, about 10.7 GB on the machine we measured: the
XTTS voice runtime, the GPU speech-to-text sidecar, the managed Python, tools,
bin, the OCR engines, and the logs. Every one of them is bound to this machine
and this processor, and every one of them costs a download to rebuild — never
data.
What stayed: your vaults, your settings and your keys don't move. The
downloaded model weights stay in ~/.mnemosyne/models deliberately — those
are portable, so they will follow your memory, not your machine, and moving
them now would mean moving ten gigabytes twice.
Nothing is deleted, and nothing waits for you. This is housekeeping, not
urgency: a first launch is never frozen for it, a folder too big to copy across
drives is simply left alone and logged, and the app looks for each folder
wherever it actually is — so a half-finished move keeps working and the next
launch picks up the rest. A virtual environment that moved is repointed at its
interpreter instead of breaking.
The one thing worth updating: any script of yours that pointed at
~/.mnemosyne/python or ~/.mnemosyne/whisper-gpu.
Underneath, every storage path now goes through one resolver, vault databases
carry stable names of their own (migrated through a dry run that refuses on a
collision, with the old name kept as a permanent fallback), and stored file paths
are relative to your memory's root — groundwork for a memory you can carry
between machines.
🚪 A first launch that offers you a choice
The model step now forks three ways: sponsored Mnemosyne credits, your own API
key, or fully local. No dead end for someone who arrives with neither a key nor
a GPU. Onboarding also proposes a workspace instead of writing a path that
leads nowhere, and the sovereign wallet greets you on first launch with a journey
card that retires itself once every milestone is won.
🪙 Credits and licenses, without leaving the app
Ask for a free license from the wallet — the request queues while you're
offline and lands in the Founders Console, which can activate or dismiss it. The
add-credit surface (card, USDT, redeemable code) is in place, a beta license
now seeds $8 of sponsored credit, and a cartridge can read your balance,
never your wallet.
🗣️ Voice installs you can watch — and stop
Installing a voice engine is now visible in the header and stoppable, names
the stage it's running, and shows real progress through the install steps. A
slow install no longer looks exactly like a hung one.
🧠 Memory that keeps up with the conversation
The app can offer to consolidate the session into memory when you close it
(and only the window that actually ends the session asks). Durable facts stated
in conversation are extracted into atomic profile memories, embedded
separately so a later correction supersedes the older fact.
✨ Around the shell
A new app icon — the brand lemniscate drawn as a ribbon. A widget reopens
at the size you closed it at. The wallet toggles between compact and full from
its header. The store gets a compact layout on narrow windows, an install-state
filter, cartridge icons drawn from the cartridge itself, and descriptions in
your language. A cartridge in its own window is named after the app. And a
hidden developer mode opens a Developer options page for people building on
the OS.
📤 Publishing without a terminal
Creators get a Publish button inside MnemoHub: sign and push to the catalog
from the app, with a staged confirmation, per-app detail cards, and a
confirmation before anything is removed.
Fixed
- MnemoHub offline says so plainly, instead of failing with a cryptic crash.
- The quit prompt no longer shows a literal
true, and cancel the close is a
real choice.

First-launch notes
- Windows: this build is code-signed (Certum OV certificate, publisher
TONY TROCHET, RFC-3161 timestamped) — the installer no longer comes from an
unknown publisher. SmartScreen builds its reputation from download volume, so
it may still warn for a while on a freshly signed identity → More info → Run
anyway. - macOS: ad-hoc signed (Apple Silicon only) → right-click the app → Open
on first launch. A real Apple Developer ID + notarization is coming. - Linux:
chmod +x *.AppImage && ./*.AppImage, orsudo dpkg -i *.deb.
Auto-update is built in: installed apps pick up future releases from this
repository automatically.
Installed separately from MnemoHub, not bundled here: the Muse app-builder
cartridge and the reworked Translator (translation + spaced-repetition
learning).
Everything above runs locally. Cloud features (optional) are strictly
key-gated and never see your vault data.
