Compare what you spend on manual customer interviews today with what Diaform Pro costs. The math speaks for itself.
Everything you need to know about Diaform plans, usage caps, and how billing works when you scale AI-led interviews.
The 14-day Trial plan is built for fast experiments—150 AI-led conversations per month, 2 live agent, up to 6 scripted questions, and 30,000 knowledge tokens so your interviewer knows what it's talking about. You also keep a branded share link on *.diaform.io.
Starter unlocks 150 monthly interviews, 2 simultaneous projects, 1 workspace seats, 10 questions, and 30,000 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. Starter expands that to 1 seats so product, research, and success teams can co-edit projects, 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.
Every paid plan offers an annual billing option that saves you roughly two months compared to paying monthly. You can toggle between monthly and annual billing on this page before choosing a plan. Annual subscriptions are billed once per year, and the per-month equivalent is shown on each card so you can compare easily. If you need a custom enterprise agreement, reach out to hello@diaform.io.
14-day Trial lets each project store up to 30,000 tokens of knowledge so follow-up questions stay grounded in your product facts. Starter raises that to 30,000 tokens, making room for long-form briefs, onboarding decks, and FAQ docs without trimming context.
