Try Passim free for 14 days

You get the whole library and the citator, inside Claude, ChatGPT, or another supported AI.

$29 a month or $299 a year per person after your trial, plus tax.

You’ll need a card to start, but you won’t be charged during the 14 days. Your plan renews automatically unless you cancel before the trial ends.

How it works

  1. Sign up with your email.We’ll send you a code. There’s no password to remember.
  2. Pick monthly or annual.Add your card through Stripe. New accounts pay nothing today. If your firm already covers you, we’ll recognize your email and skip this step.
  3. Add Passim to your AI.We’ll walk you through it for ChatGPT, Claude, or another assistant. Then ask your first question.

On a firm or company AI account, your administrator may need to turn on Passim first.

  • Claude: every plan. On Team and Enterprise, an Owner has to add it first under Organization settings, then Connectors. Set it up on the web or desktop and it’ll be on your phone the next time you sign in.
  • ChatGPT: Plus, Pro, Business, and Enterprise, though availability can vary by region and workspace. On Business and Enterprise, an admin manages it under Workspace settings, then Plugins.
  • Gemini: personal Google accounts only, in the U.S., 18 or over, in English, with Keep Activity on. Add it on the Gemini website and it works in the phone app. Google says people may review these chats, so keep client facts out.
  • Perplexity: Pro, Max, and Enterprise. On Enterprise, an administrator has to allow custom connectors first. Add it on the web.
