Pi Reads

Pi Reads turns web pages, RSS/Atom entries, exported newsletters, explicit clipboard captures, timestamped transcripts, pasted text, Markdown, and local files into a private reading library inside Pi. Keep a faithful copy, create a cited digest or synthesis, and export it to Markdown, HTML, PDF, EPUB, Obsidian, or Kindle.

What it does

• Faithful archive — captures the source without AI rewriting, reuses exact duplicates, and links explicitly recaptured versions.
• Digest — creates a shorter, cited version.
• Synthesis — creates a new, cited article from source ideas.
• Local library — stores sources, articles, provenance, exports, and separate reading state under ~/Documents/pi-reads, with offline search and deterministic queues.
• Reading destinations — exports to local files, Obsidian, and Kindle.
• Safe delivery — asks before overwriting Obsidian files or sending Kindle email.

Archive content and AI-authored content are always stored separately. Mixed URL/file/text collections can use reads_ingest batch mode: bounded concurrent acquisition, per-item outcomes, duplicate reuse, and cancellation without discarding successful captures. RSS/Atom feeds and local newsletter .eml files use duplicate-aware no-write previews followed by explicit entry selection. See batch ingestion and feed/newsletter ingestion.

Quick start

Requirements: Node.js 24+ and Pi.

pi install npm:pi-reads

In Pi, capture an article:

/reads https://example.com/article

Choose a mode:

Mode	Use it when you want…
archive	the source captured faithfully
digest	a shorter cited reading version
synthesis	a newly written cited article

Digests use verified complete-source coverage. Focused syntheses may use targeted coverage, which records omitted sections and carries a non-comprehensive warning. Long sources are traversed through bounded continuation cursors rather than one unbounded model-context load. Before saving generated work, Pi Reads resolves citation locators, verifies quoted text against immutable sources, and reports bounded uncited-section diagnostics.

For an ordered synthesis from several existing captures, run /reads, choose Captured sources, and select 2–20 sources in order. Pi Reads plans bounded retrieval for each source and requires a no-write review that reports citation distribution and unused selected sources before the exact draft can be persisted. Generation templates provide versioned brief, deep-dive, tutorial, comparison, and research-note structures with deterministic length/citation warnings. See multi-source cited synthesis and generation templates.

Then choose an output such as Markdown, PDF, EPUB, Obsidian, or Kindle. To combine 2–50 saved articles, run /reads and choose Reading pack; Pi Reads prepares a validated ordered multi-chapter EPUB locally. See reading packs and scheduled Kindle preparation.

For the first PDF export, install Chromium once:

/reads-install-browser

Browse or privately search saved articles with:

/reads-list
/reads-search <query>

Search uses a rebuildable local BM25-style lexical index—no model, embeddings, or remote search service. Run /reads-rebuild-search for an explicit rebuild; missing or corrupt indexes recover automatically.

Track progress without changing immutable articles:

/reads-state <article-id> reading
/reads-queue

States are unread, reading, completed, or archived. Tool workflows can also set tags, rating, priority, and due/read-later dates with revision-conflict protection.

Obsidian

Run /reads-config, choose Obsidian destination, and select your vault and inbox folders. Pi Reads writes a Markdown note, copies its images, preserves provenance, and asks before replacing a conflicting file. After exporting notes, /reads-obsidian-graph builds managed library/topic/status/queue views and adds source-note links to exported syntheses; source/archive note bytes stay unchanged.

You can also set the vault directly:

/reads-config obsidian ~/Documents/MyVault

See Obsidian integration.

Kindle

Run /reads-config, choose Kindle delivery, then choose System credential store — configure once. The wizard saves your Kindle and SMTP credentials in macOS Keychain, Windows Credential Manager, or Linux Secret Service. The password is masked and credentials are not written to pi-reads.json.

A Kindle export starts as a dry run, showing the recipient and retaining an immutable EPUB or PDF without sending it. Ask Pi to send that prepared export when ready; Pi verifies and reuses the exact previewed bytes, displays the full recipient, and requires confirmation before email delivery. The scheduler-safe pnpm kindle:digest:prepare command can build collection EPUBs locally, but has no unattended send capability.

For iCloud Mail settings and CI environment overrides, see EPUB and Kindle delivery.

Commands

Command	Purpose
/reads	Capture/export content, synthesize sources, or prepare an ordered reading pack
/reads-config	Configure the library, Obsidian, or Kindle
/reads-list	Browse saved articles
/reads-search <query>	Search local metadata and archive/generated prose
/reads-state <article-id> [status]	Show or update reading status
/reads-queue [status]	List/filter the deterministic reading queue
/reads-obsidian-graph [overwrite]	Build managed Obsidian views and synthesis backlinks
/reads-rebuild-search	Rebuild the derived local search index
/reads-install-browser	Install Chromium for PDF export

Pi Reads also provides the reads_ingest, reads_save_article, reads_export, and reads_library tools for agent-driven workflows. reads_ingest reports canonical-URL changes without writing; recapture: true requires explicit approval and creates linked immutable versions. reads_library supports byte-bounded source outlines, exact heading/paragraph range reads, and lexical excerpts so the model can retrieve only the evidence it needs.

Library maintenance

Verify records, rebuild derived indexes, and create portable local backups with pnpm library:maintain from a checkout (or the installed scripts/maintain-library.ts). Restore only creates a new library directory and never merges or overwrites an existing one. Stop library writers first; credentials and destination settings are excluded.

See verification, backup, and restore for commands, limits, and migration steps.

Privacy and safety

• Your library stays outside the installed package and is not uploaded by Pi Reads.
• Archived source prose is immutable and separate from generated prose.
• Generated articles retain source IDs, citations, model information, and timestamps.
• Mutable reading state is revisioned separately and never changes source or article manifests.
• Kindle credentials stay in the operating-system credential store; environment overrides are available for CI.
• Kindle sending and conflicting Obsidian overwrites require interactive confirmation.

See the product contract and security policy for details.

Updating or removing

pi update npm:pi-reads
pi remove npm:pi-reads

Removing the package does not delete the external reading library.

Development

pnpm install --frozen-lockfile
pnpm article:install-browser
pnpm release:check
pnpm benchmark

The original deterministic article:* print workflow remains supported. Contributor guidance is in CONTRIBUTING.md, benchmark usage is in docs/benchmarks.md, and release instructions are in docs/releasing.md.
