Proseview

A local dashboard and AI harness for novelists who write in Markdown. ✍️

Proseview reads your manuscript folder, gives you a writer-grade view of its structure and prose, and turns the same surface into a place where you can read, edit, annotate, and bring an AI assistant to any paragraph without leaving the page.

It runs entirely on your machine. No cloud, no telemetry, no lock-in. Your files stay where they are.

✨ What you get

• 📊 Dashboard. Word count, chapter pacing, lexical health (MATTR / MTLD), sentence-rhythm variance, character presence, location stickiness, character co-occurrence, plus a sortable scene table.
• 📖 Reading view. Open a scene as a typographic page with a real reader font. The dashboard chrome gets out of the way.
• ✏️ WYSIWYG editor. ProseMirror-backed. Same surface as the reading view, just with Edit toggled on. Mod-S saves. Conflict guard checks the file mtime so a concurrent change in your editor never gets silently overwritten.
• 🎨 Editorial highlights. Toggle nine prose passes on top of any scene: repetition, passive voice, filter verbs, crutch words, hyperbole, lyrical reach, sensory density, comedy beats, first-person rate. Each pass is a single click.
• 🗒️ Inline TODOs and Notes. Select a passage, drop a TODO or a tagged NOTE (continuity / character / theme / question), and it lands in the file as a Markdown comment. Survives in git.
• 🤖 AI on the selection. Send the highlighted passage to Codex, Claude, or Gemini in one click. An in-browser terminal hosts the conversation; the agent can see the file, the selection, and your repo. Your tools, your prompts.
• 💬 Discuss with Codex. Open a document-aware conversation beside any scene or supported repository text file. Prosview sends the current document automatically and only adds selections, files, or folders you explicitly attach. Safe progress summaries, plans, tool activity, approval requests, and streamed answers stay visible while you read.
• 🧰 In-browser terminal. xterm.js wired to a real PTY. Run codex, claude, or any shell command without leaving the dashboard. Tabs persist across page reloads.
• 🔁 Live reload. Save a file in your editor and the dashboard picks up the change over Server-Sent Events. No manual refresh.
• 🔗 Deep links. Every scene and file has a URL. Copy the address bar to share or revisit a view. Back / forward work.
• 🔎 Repository search. Press Mod-K or choose Search from any dashboard, scene, or file view. File paths come from one repository-wide inventory; opening a result loads its preview lazily and reopening Search preserves the current query.
• 🎨 Themes and fonts. Light, Dark, Docsify, Hopscotch. Reader, Literary, Inter, Georgia, Baskerville, Sans, Mono.
• 🧪 Tested. 260+ tests: unit coverage of the analytics engine, scene parsing, save guards, history, and refresh behavior, plus end-to-end tiers that boot the real server and drive the real UI in a browser.

🚀 Quick start

git clone https://github.com/ourarash/prosview.git
cd prosview
pip install -r requirements.txt

# Run the dashboard against your novel repo
python -m proseview --root /path/to/your/novel

A browser tab will open at http://localhost:7842. Press Ctrl-C to stop.

If you'd rather install proseview as a tool:

pip install -e .
proseview --root /path/to/your/novel

📁 What proseview expects

A folder of Markdown scene files, one folder per chapter. The minimum viable repo:

my-novel/
├── manuscript/
│   ├── ch01/
│   │   ├── 01-opening.md
│   │   └── 02-meeting.md
│   └── ch02/
│       └── 01-aftermath.md
└── .proseview.yaml          # optional

Scene files use simple frontmatter:

---
title: Opening
chapter: Chapter 1
status: draft
where: A bar in the West Village
when: Friday night, late
pov: Nima
characters: [Nima, Mira]
goal: Nima needs to get the question on the table
conflict: He's afraid she already has someone
outcome: She agrees to dinner; he leaves rattled
todos:
  - Tighten the opening paragraph
---

# Opening

The bar was loud and the music was bad...

Every field is optional. Proseview reads what's there and falls back gracefully on what isn't.

📝 Frontmatter contract

These are the keys proseview recognizes. Any other keys are passed through and ignored. Every field is optional.

Identity

• title (string) header of the scene viewer; defaults to a Title-Case version of the filename stem.
• chapter (string) "Chapter" column in the scene table and the chapter rows of charts; defaults to the chapter folder name.
• status (string) color-coded status badge. Conventional values: draft, revision, done. Anything else renders as a generic chip; missing means unknown.

Scene context

• where (string) "Where" row in the scene card. Also feeds the Setting Stickiness chart (Words per Location).
• location (string) synonym for where (older convention).
• when (string) "When" row in the scene card. Free-form.
• pov (string) "POV" row in the scene card. Free-form.
• characters (list of strings) "Characters" row in the scene card; each name is clickable to open the bio if <characters_path>/<name>.md exists. Also feeds the Character Presence and Co-occurrence charts.

Arc

• goal (string) "Goal" row in the arc panel.
• conflict (string) "Conflict" row in the arc panel.
• outcome (string) "Outcome" row in the arc panel.

Tasks

• todos (list of strings) each entry shows up as a frontmatter-level TODO in the Tasks panel. Inline <!-- TODO: ... --> comments inside the prose are picked up too and get a line anchor.

A scene with no frontmatter still renders, just with Unknown / Not defined placeholders in the scene card and the file's stem as its title.

⚙️ Configuration

proseview works with zero config. Drop a .proseview.yaml at the repo root if you want to customize:

# Where the manuscript lives. Default: manuscript/
manuscript_path: manuscript/

# Where character bios live. Default: story-bible/characters
characters_path: story-bible/characters

# Where AI skill prompts live. Default: skills
skills_path: skills

# Word-count goal for the finished book.
target_words: 80000

# Daily word goal (drives the "days to finish" estimate).
daily_target: 500

# Healthy band for local lexical variety (MATTR).
mattr_band: [0.74, 0.77]

# Healthy band for whole-scene lexical variety (MTLD).
mtld_band: [105, 130]

# Editor URL handler. One of: vscode, cursor, zed, positron, custom.
editor:
  scheme: vscode

# Folders shown in the file tree alongside the manuscript.
repo_tab:
  folders: [plans, continuity, outline, story-bible, docs, templates]

Every key has a sensible default; missing folders are simply skipped.

🧠 The analytics

Lexical health is real, not vibes:

• 📐 MATTR (moving-average type-token ratio, window 100). Measures local vocabulary variety. Low = the same words inside a paragraph; high = constant rotation that may feel jittery.
• 📐 MTLD (measure of textual lexical diversity). Measures whole-scene variety. Low = the scene keeps circling the same ground; high = the scene keeps reaching.
• 📐 Sentence rhythm. Per-chapter standard deviation of sentence length. Static / Rhythmic / Dynamic zones are annotated on the chart.
• 📐 Dialogue percentage, passive voice rate, crutch-word rate, first-person density, sensory density, filter-verb rate, paragraph length.

Every scene gets a row in the deep-dive table; outliers get listed under Editorial Alerts with a one-line revision signal.

🤝 Working with AI

Four places where AI shows up, all opt-in:

1. Selection menu. Highlight any text in a scene. The pill that appears includes Add TODO, Add Note, and (if the corresponding tools are installed locally) Run in Codex and Skills. Skills are reusable prompts you keep in skills/<name>/SKILL.md; they show up automatically in the menu.
2. Agent menu. From the scene header, launch a conversation with Codex, Claude, or Gemini scoped to that file. The conversation runs in the in-browser terminal so you can keep reading the prose underneath while the agent works.
3. Discuss. Choose Discuss in a scene or text-file header to use the shared right utility dock. Prosview starts the local codex app-server lazily, uses your existing Codex login and configured model, and keeps full history in Codex's normal storage. Prosview persists only a hashed document-to-thread mapping in your user state directory. Raw reasoning is discarded; only Codex-authored progress summaries reach the browser. Tool and file actions remain subject to visible, user-reviewed approvals. If a stored Codex thread disappears, Prosview starts a replacement on the next question instead of leaving the document stuck. Use New conversation to intentionally clear the document's current discussion; the prior thread remains available in Codex history. The visible document is attached by default for each question; remove its context chip to omit it, or use the compact add-context control (keyboard shortcut @) to attach repository files and folders explicitly.
4. TODOs as Markdown. Every TODO and Note is a plain <!-- TODO: ... --> or <!-- NOTE[tag]: ... --> comment in the scene file. Your AI assistant can see them through the file, your repo can track them through git, and you can grep them.

🛣️ Roadmap

This is alpha. Things that are working and things that are coming:

• ✅ Live server, live reload, ProseMirror editor, highlights, TODOs, notes, deep links, in-browser terminal, agent menu, and document-aware Discuss conversations with Codex.
• ✅ Vendored front-end dependencies. chart.js, marked, xterm and friends ship with the package and load from /vendor/. ProseMirror modules are pinned to specific versions on esm.sh.
• ✅ Modularized front-end. The JS lives in nine topical files under templates/assets/js/, concatenated at render time.
• ✅ proseview init writes a starter .proseview.yaml so a fresh novel repo gets a working configuration with one command.
• ✅ Persisted UI prefs. Your highlight-pass toggles and theme choices survive scene navigation and reloads.
• 🚧 Diff-confirm for AI-suggested edits (selection runs in a terminal today; nothing applies edits without your approval, but the diff UX is still terminal-only).
• 🚧 Configurable agent list (Codex / Claude / Gemini are presets today).
• 🚧 Continuity surfacing (warn when a scene contradicts a known fact).
• 🚧 Frontmatter editor (status, where, todos) inside the scene viewer so you don't need to drop into your text editor for routine fields.

See plans/roadmap.md for the full punch list.

🧪 Development

pip install -e ".[dev]"
pytest

That runs the unit suite plus an HTTP end-to-end tier that boots a real proseview subprocess and drives every endpoint — saves and the conflict guard, TODOs and notes, the AI proposal bridge through the actual CLI, live reload over SSE, and PTY terminals — asserting on bytes written to disk. Discuss integration tests use a deterministic fake app-server and isolated home/state directories; they never contact Codex, the network, or your profile. ~15 seconds, no extra dependencies.

A browser tier drives the real UI in Chromium (editor round-trip fidelity, the selection menu, highlight passes, deep links, agents, terminals, Discuss streaming/approvals/shared-dock behavior, and applying an AI proposal end to end). It's opt-in:

pip install -e ".[e2e]"
python -m playwright install chromium
pytest -m e2e_browser

Both tiers work on a throwaway copy of fixtures/demo-repo. See CONTRIBUTING.md for details.
