Not another AI legal tool

Five things the generic tools don't do

Searches the internet and hopes
A closed library of NY primary law. The model cannot cite a document that wasn't retrieved, so a fabricated citation is structurally impossible.
A verification disclaimer
Verification you can watch: every quotation compared word for word with the source text, every citation checked against 5.1M official records back to the 1800s.
Fifty states, an inch deep
One jurisdiction, all the way down: DHCR bulletins and fact sheets, Housing Part decisions, ETPA, the Rent Stabilization universe no national tool stocks.
Knows the law, not your building
Mention a NYC address and the answer is grounded in that building's record: stabilization indicators, HPD violations, ownership, eviction history.
Stores your research as a feature
Stores nothing. Questions never touch our servers' storage, history lives in your browser, and documents you check are processed in memory. What we don't hold can't leak or be subpoenaed.

Answers an attorney can stand behind.

Ask in plain English. Casewise retrieves the controlling New York authorities (statutes, ten years of decisions, DHCR guidance, court rules) and drafts a structured answer where every assertion carries a citation. Quoted language is string-matched to the source, word for word, and the check is shown with the answer.

Check cites

Audit any filing in seconds, including theirs.

Paste a brief or upload a PDF or Word file. Every citation is verified: statutes and rules against the corpus, case law against a catalog of 5.1 million published citations. Real authority comes back with its case name and year. Fabricated authority comes back in red.

Building records

Analysis grounded in the actual building.

Mention a NYC address and the answer reflects that building's public record (rent-stabilization indicators, open HPD violations by class, the registered owner, eviction history), cited like any other source, linked to the underlying data.

Built for the work on your desk.

Holdover & nonpayment defense

Notice periods, rent demands, service windows, and the housing-part rules, with the controlling section quoted, not paraphrased.

Rent-stabilization questions

Guideline increases, IAI and MCI rules, Good Cause coverage, deregulation history, grounded in DHCR's own bulletins and fact sheets.

Habitability claims

The warranty's elements, the building's actual violation record, and a decade of Appellate Term outcomes on both sides of the ledger.

Designed for attorney confidentiality.

Your questions stay yours

Nothing you ask trains any model. We keep no central log of questions; research history lives in your own browser. No ad trackers, no cookie banners, nothing to opt out of.

Verification by construction

The drafting model can only cite sources retrieved for your question. Citations are mapped to real documents server-side; a fabricated cite cannot reach you. Quotes are matched character-for-character.

Primary sources, always

Every citation links to the official text: nysenate.gov, nycourts.gov, hcr.ny.gov. One click from answer to authority. Verify everything; the product is built to make that fast.
