Precedent Ai — Vision & Product Direction

The fastest way for lawyers to find the right cases and paste-ready, citable reasoning—without hallucinations or bloat.

One‑liner

Precedent Ai is the fastest way for lawyers to find the right cases and paste‑ready, citable reasoning—without hallucinations or bloat.

Why this matters now

Lawyers spend hours sifting through irrelevant hits or cleaning up Ai drafts that can't be trusted. Generic LLMs write fluent answers but routinely invent cites. Full‑stack tools (Westlaw/Lexis) are comprehensive but heavy and expensive for narrow tasks.

There's room for a focused, high‑trust copilot that does one thing extraordinarily well: on‑point precedent with page‑accurate citations.

Focus

We launch with tightly scoped precedent packs—topic- and jurisdiction-specific collections where we can guarantee high recall and precision (e.g., restrictive covenants, trade secrets, wage & hour). We'll expand to adjacent topics and jurisdictions based on demand.

Corpus: Curated, published appellate opinions from selected jurisdictions (1990→present + key anchors).

Outcome: Get to controlling cases and citable reasoning in minutes; confirm treatment/statutes/secondary sources in your full‑stack tool.

How we're better than a generic LLM

Grounded answers only: All reasoning is sourced to real opinions in our corpus.
Zero‑hallucination mode: Quotes must match source bytes; we attach pincites to the exact page.
Jurisdiction‑aware ranking: Prioritize CA Supreme/Ct. App., then 9th Cir. applying CA law; down‑rank off‑topic noise.
Citator‑lite: Graph‑based treatment signals (followed/limited/criticized) so you see risk at a glance.
Task‑fit summaries: Case cards extract holding, rule/test, posture, key facts, and 2–5 quotes—not generic prose.

How we differ from full research suites

We're not trying to replace Westlaw/Lexis. We are the fast, focused layer lawyers open first.

Product principles

Precedent‑first

Do cases exceptionally well before anything else.

Citable by design

Every claim is traceable to a page; no orphaned assertions.

Trust > coverage

Narrow scope, high authority, predictable results.

Speed to value

Time to first on‑point case < 30 seconds.

What a user sees (Case Card)

Each opinion renders as a standardized case card:

• Citation, court, year

• Disposition & procedural posture

• Issue(s) and holding (1–2 sentences)

• Rule/test (controlling standard)

• Key facts (material only)

• 2–5 verbatim quotes with pincites

• Statutes referenced (e.g., B&P §16600/§16601, Lab. Code §925)

• Treatment (citator‑lite): followed/criticized/limited/distinguished

• Topic tags: non‑compete, non‑solicit, sale‑of‑business, choice‑of‑law, NDA‑overbreadth, etc.

How it works (under the hood)

Curated corpus: Seeds (landmark cases per pack) → forward/backward expansion → inclusion filters.

Dual‑stage retrieval: BM25 + dense vectors → legal cross‑encoder re‑ranker tuned to holding/standard similarity and statute hits.

Extraction: LLM‑assisted case card generation with byte‑verified quotes and page map for pincites.

Citator‑lite: In‑corpus citation graph + stance heuristics for quick risk signals.

Guardrails: Refuse to cite anything not found in corpus; never fabricate cites or pincites.

Roadmap

Near term: Launch targeted precedent packs; case cards; "more like this"; export Bluebook citations with pincites.

Next: Citator‑lite signals; statute anchors; saved searches; judge/court filters.

Later: Motion snippets (MTS/MTD/MSJ) with inline citations; team folders; shareable research trails.

Expansion: Add adjacent topics and more jurisdictions based on demand.

What we won't do (for now)

  • Replace KeyCite/Shepard's.
  • Host full statutory/regs libraries or treatises.
  • Be nationwide or all‑practice‑areas.

Who it's for

Litigators, in‑house counsel, and practitioners who need fast, reliable case pulls and motion‑ready quotes.

Users who prefer to open a focused copilot first, then validate in Westlaw/Lexis.

FAQ

Is this a replacement for Westlaw/Lexis?

No. It's a copilot for precedent discovery and drafting. You'll still confirm treatment and explore statutes/secondary sources in your full‑stack tool.

How do you prevent hallucinations?

We only output quotes that match the opinion's bytes and attach page numbers. If we can't verify, we don't show it.

What about unpublished opinions or trial‑court orders?

Not in MVP. We start with published, precedential CA Supreme/Ct. App. + 9th Cir. applying CA law.

Why start with focused precedent packs?

Because narrow, well‑curated corpora produce higher precision, trustworthy citations, and faster time‑to‑answer. We expand breadth only when we can maintain that standard.

Precedent Ai is built to be the research tab you open first—because it gets you to controlling authority and citable reasoning faster than anything else.
