Start free, learn fast, and scale to richer interviews when you’re ready. Every plan keeps the AI interviewer, public links, and automatic transcripts included.
Everything you need to know about Diaform plans, usage caps, and how billing works when you scale AI-led interviews.
The Free plan is built for fast experiments—20 AI-led conversations per month, 1 live agent, up to 4 scripted questions, and 20,000 knowledge tokens so your interviewer knows what it's talking about. You also keep a branded share link on *.diaform.io.
Pro unlocks 500 monthly interviews, 3 simultaneous agents, 3 workspace seats, 20 questions, and 75,000 knowledge tokens. Advanced analytics (conversation sentiment plus keyword/topic insights) are also included. Pricing is $29/month (regularly $49).
We start counting the moment someone starts a conversation via your unique /c/[conversationId] link. Follow-up probes, retries, voice inputs, and summaries stay inside that single conversation, so you only consume one credit per respondent.
Conversation credits reset on the first day of every billing cycle and do not roll over. This keeps forecasting simple and lets you right-size capacity—upgrade to Pro or contact us for a custom plan if you consistently hit the cap.
Yes. The Free plan includes 1 seat for the workspace owner. Pro expands that to 3 seats so product, research, and success teams can co-edit agents, review transcripts, and export summaries together.
We notify you in-app and via email as you approach the quota. Interviews in progress will continue through the end of the billing period, and you can either upgrade immediately, schedule a higher plan with our team, or pause new links until the counter resets.
Yes. If you need more than 500 conversations a month, custom analytics, or procurement paperwork, reach out to hello@diaform.io and we’ll scope an annual or enterprise agreement that matches your volume.
Free lets each agent store up to 20,000 tokens of knowledge so follow-up questions stay grounded in your product facts. Pro raises that to 75,000 tokens, making room for long-form briefs, onboarding decks, and FAQ docs without trimming context.
Start an interviewer in seconds, share the link, and let the AI handle the rest. No more chasing feedback. No more guesswork.
