Picard OSS demo: vault, tabular review, and citation-grounded chat

Features

Evidence-first legal AI — your way.

Everything incumbents promise, in a codebase your firm can run, inspect, and control.

Assistant

A chat interface that reads your documents, gives grounded citations, and refuses when evidence is missing.

Picard OSS

Citation-grade chat with bbox PDF highlights, refuse gate, and local SQLite — documents stay on your machine.

Picard.law Cloud

GraphRAG assistant with enterprise vault, multi-user projects, and cross-document intelligence at scale.

Workspaces

Matter-scoped workspaces. Upload agreements and diligence packs; the assistant keeps context across every document.

Picard OSS

Local matters with data under `.picard-data/` — no cloud account, no Supabase, single-user air-gap friendly.

Picard.law Cloud

Cloud projects with firm-grade auth, shared vaults, and matter-scoped context for distributed teams.

Tabular review

Spreadsheet-style extraction across many documents. Every cell should be verifiably cited back to a page and quote.

Picard OSS

FTS5 + LLM cells, SSE batch runs, flags, Excel export, and review chat with citations — shipped in OSS today.

Picard.law Cloud

Full tabular review with graph-backed extraction, dynamic schemas, and enterprise-scale parallel runs.

Search & retrieval

Find the right clause fast — exact legal language matters more than semantically similar boilerplate.

Picard OSS

BM25 full-text plus CARP multi-constraint retrieval on SQLite FTS5 — no vector DB required.

Picard.law Cloud

Neo4j GraphRAG, RDF-style relationships across parties and clauses, and sub-60s cross-document answers.

Why open source

Your firm's AI, on your own terms.

Run Picard OSS locally, or use Picard.law Cloud when you need managed infrastructure.

Zero license cost.

No vendor lock-in and no per-seat pricing that rises every year. AGPL covers local dev and PoC; you pay model API costs with your own keys.

Self-hostable by design.

Picard OSS runs on a single machine with documents under `.picard-data/`. Picard.law Cloud is managed on Azure when you want a hosted path.

Fork it. Extend it.

Add practice-specific workflows, integrate your DMS, or wire your own citation engine. The codebase is yours to shape.

Audit every line.

No black boxes around prompts, CARP retrieval, or the refuse gate. Open code and open prompt engineering you can review.
