Most civil disputes in the U.S. are money disputes too small for a lawyer and too stressful to ignore. Kashtab sits in the middle: it reads the letter, shows what others paid, gives both sides a private room, and compares sealed offers without ever revealing them.
Paste a demand letter. A rule-based reader finds the kind of claim, your deadline, the amount and the sender — each fact with the sentence it came from. Runs in your browser.
See what's publicly reported for letters like yours — with sources and sample sizes — and which terms usually move. No verdicts, no valuations.
Invite the other side with a link and a passphrase. Talk on the record with a tone check in the middle. Keep private notes on your side of the screen.
Each side enters its real limit in private. The room says only whether a deal exists — cash, close, or no. Up to six rounds.
The thing that makes these disputes drag on is the fear of naming a number first. In a Kashtab room nobody names it first — both sides seal a limit, the server compares them, and everyone learns one thing: whether there is a deal to find.
Illustration. The numbers are blurred because that's exactly what each side sees: nothing.
Any dispute where money — or money plus a fix — can end it.
We'd rather say it plainly than have you find out later.
Nothing here is legal advice. The reader explains what a letter says; it never tells you what your case is worth or what to do. When a matter needs counsel — harassment, discrimination, wages, safety, minors, criminal, government — it says so and stops.
Kashtab decides nothing and recommends no number. It's a neutral place and a neutral comparison. Both of you keep every right you had before you opened the room.
Replies, invites and offers leave from your own email with your name on them. No e-signature, no payments and no auto-drafted agreements yet — those are on the roadmap, not on the site.
Yes, during the pilot. Reading a letter is free and runs in your browser. Rooms and sealed offers are free. If that changes, existing rooms stay open.
Nowhere. The reader runs on your device; the text is not uploaded, stored or used to train anything. The only exception is the optional AI read, which sends the text once when you click, to Kashtab's server and to Anthropic's API, and stores nothing.
No. Your sealed limit is stored and compared on the server and never returned to anyone — not to the other side, and not to you after you seal it. The room only reports whether the two limits overlap, and which non-cash terms you both accepted.
Then you still have a dated record, your facts and your draft reply. Most demand-letter senders respond to a calm, documented reply — with or without the room.
Named public sources (court filings reports, defense-firm guides, statutes). They're labeled on every page. Kashtab publishes its own medians only after 20 matters close in a category — and says "n = 0" until then.
Not yet. The reader, the price data and the templates are built for U.S. law and U.S. letters.
