The research coworker for public servants. 10,000+ jurisdictions of statutes and codes, your agency’s own archives, and every source your team already trusts — researched, cited, and shipped as work product.
Works with the tools you already run
Most answers are already on the books. In state code, in your archives, in a staff report from four years back. Mesa finds it and cites the line — in seconds or minutes, not quarters.
Plain-language questions
Ask the way you'd ask a senior analyst. Mesa picks the right sources, reads the provisions, and comes back with an answer — not ten tabs of search results.
Answers that hold up
Every claim is traced back to the provision, page, or passage it came from.
Conversations that compound
Threads persist across sessions so a long-running project picks up where you left off — or where a colleague did.
See the source
Hover shows the full cited passage in context, so reviewers can confirm the cite without leaving the page.
Jump to the code
One click drops you into the full hierarchical code — title, chapter, section — at the exact provision the agent used.
Audit the trail
Every response records every source the agent consulted. Export the trail for counsel, a peer, or the record.
Scope before you run
Mesa proposes which provisions to examine, what criteria to evaluate, and what to extract. You approve the scope before a single token runs.
Provision-by-provision
Each provision is individually evaluated against your criteria. Catches what keyword search misses — synonyms, indirect references, structural cross-refs.
Built to hand off
Output is a sortable, filterable table. Export to CSV or JSONL. Embed a live preview in a research document. Hand it to counsel as-is.
Compare peers in one view
Rows for peer jurisdictions, columns for the provisions you care about, every cell cited to its source. No forty browser tabs.
Find what works and cut what doesn't
Mesa maps the overlaps, conflicts, and dead weight across peer codes so your team can streamline rules and unlock benefits that outdated language is blocking.
Borrow precedent, don't guess
Turn "what could we write" into "what eight peer cities did, with citations." The first draft starts with precedent baked in.
Fast
Direct answers and quick lookups. For the moments when you already know the statute and just need the text, or when the question is straightforward.
Balanced
Targeted research across the relevant codes. The default for most questions.
Deep Research
Exhaustive multi-jurisdiction investigation with parallel agents. For the memo, the briefing, the compliance review — work that has to hold up to scrutiny.
Versioned revisions
Every save is a revision. Roll back, diff two versions, or hand a frozen snapshot to counsel while you keep editing.
Share without seats
Publish a link. Recipients read, copy, and cite without ever creating an account — or paying for a seat.
Structured handoff
Embed datasets, tables, and source links inline. Exports to PDF and DOCX when the recipient needs paper.
General-purpose AI and even dedicated legal tools confidently miss 86–96% of the provisions they should find. We know because we benchmarked them against a peer-reviewed methodology.
Mesa finds 99.8%.

Mesa maintains a continuously updated library of the statutes, municipal codes, and administrative regulations governing every major US jurisdiction — plus the long tail. Around that library sits live web search, your internal document repositories, and a growing shelf of custom connectors for the systems your agency already runs.
Statutes & codes
State statutes, municipal codes, county ordinances, and administrative regulations — hierarchically browsable, continuously updated, versioned for time-travel queries.
Live web search
Agency press releases, news coverage, peer cities' public records. The web, treated as one more first-class source with the same citation rigor.
Your internal systems
Custom connectors to the platforms your agency already runs — ECM, permitting, GIS, agenda management, codified law, video archives, and more.
Connectors
Mesa reads from the platforms your teams already use, so nothing has to move to get started. If your stack isn’t here yet, .
