Parchwell
In development · for macOS

Private AI for the documents you can't upload.

Parchwell reads the files on your own Mac and answers questions about them — citing the page each answer came from. The AI runs on your machine. Your documents never leave it.

No signup form, no tracking on this page. Just an email address if you want one.

Runs on your MacThe model, the search index and the answers — all local.
Every answer cites its pageClick a citation, the document opens where the answer came from.
Says "I don't know"Chosen for refusal behaviour. A model that invents a capital city will invent a payment amount.
A log you can hand an auditorFingerprinted and chained, so an entry can't be edited without it showing.

Built for people whose files can't go to a chatbot

The tools that are good require giving up the data. The tools that keep the data aren't good. Parchwell exists because that trade shouldn't be necessary.

Bookkeepers & accountants

Receipts, statements and returns for clients who never agreed to have their finances uploaded anywhere.

Lawyers

Privilege doesn't survive a paste into a chatbot. Ask across a matter's documents without anything leaving your Mac.

Clinicians & care providers

Patient records carry obligations that don't pause because a tool is convenient.

Anyone under an NDA

Contracts, board packs, diligence rooms — material you're contractually forbidden to hand to a third party.

How it works

Four steps, none of which involve uploading anything.

Make an engagement

A container for one piece of work — a client, a matter, a case. Each keeps its own documents and its own privacy setting.

Add your documents

Point it at folders on your Mac. Parchwell reads and indexes them locally, encrypted at rest.

Ask, or generate

Ask questions in plain language, or generate a briefing, a data table, a chart or a timeline from the sources.

Check the answer

Every claim carries a citation. Click it and the document opens at that page. Counts and totals are computed from your files, not guessed by a model.

Privacy you can check, not just be promised

"It's local" is easy to say and impossible for a buyer to verify. Parchwell is built so a sceptic — or a compliance officer — can check every claim on this page.

  • No account, no server, no telemetry. There is nothing on our side to breach, because there is no our side. We couldn't read your documents if we wanted to.
  • Encrypted at rest. The index — which holds the text pulled out of your documents — is encrypted with a key held by your Mac. A stolen laptop yields nothing.
  • A verifiable audit log. Every document indexed, question asked and answer given — recorded, fingerprinted and chained. Export it for a compliance review.
  • A screen that shows everything stored — and erases it. Real paths, real sizes, then a re-scan of the disk to prove it's gone.

Being straight with you: Parchwell is still in development and not yet for sale. An optional "cloud assist" mode is planned for harder questions — when it ships, your documents still won't leave: the on-device AI will write a masked summary, with names and numbers replaced, and only that will go out. It will be off by default, chosen per engagement, and every summary sent will be shown to you and recorded in the audit log. Until it exists, everything happens on your Mac.
