Built for work where a wrong answer has consequences.
A verifiable AI coworker that coordinates multiple agents and real tools to read your files, run the analysis, and cite the source behind every claim, across legal, financial, research, and coding work.
One account across Perch AI Web, Desktop, and the CLI. Same memory, same sourced answers.
Citation proof
The source stays attached.
Every claim points back to the material Perch actually read. Unsupported lines get marked or removed before they reach the final draft. You can check every reference yourself.

How it works
Reads first. Delivers through your browser.
Perch starts by reading the files in your folder. Then it works inside the apps you are already signed into: creating docs, writing emails, opening calendar invites. Every action leaves a receipt you can check.
Folders, email, calendar, docs, sheets, decks, Slack, Notion. If it runs in your browser, Perch can work there.
Two ways it works
Two working styles. Same workspace.
Use Saffron when the folder needs pressure and judgment. Use Quill when the draft needs structure, sources, and taste. Switch when the work changes.
Saffron · Operator
Run the AP audit on March vendor payments.
Checking invoices, bank exports, and vendor names across the folder. I am matching by amount first, then date drift.
Found a duplicate payment: INV-88421 processed twice on March 8 and 10, $94,890 each (Greenfield Materials).
Quill · Writing Companion
Write a memo on personal jurisdiction.
Reading first. What jurisdiction analysis are you running? Federal or state?
Federal. Minimum contacts test.
Draft's in the canvas. The argument I'd watch is the second section: Walden applies harder here than Calder. Want me to tighten it?
