Pricing questions, answered
Everything you need to know about Diaform plans, usage caps, and how billing works when you scale AI-led interviews.
What does the Starter plan include?
Starter gives you 500 assistant messages per month, 1 live projects, 1 workspace seats, up to 6 scripted questions per conversation, and 30,000 knowledge tokens. It is the paid entry point for teams replacing manual customer calls with always-on interview links.
When should I choose Pro, and how much does it cost?
Pro is built for teams that need more throughput and collaboration. It includes 3,500 monthly assistant messages, 10 simultaneous projects, 5 seats, 15 questions per conversation, 30,000 knowledge tokens, advanced analytics, and branding removal. Pricing is $199/month.
What if I need more than the Pro plan?
Business is the next step up: 10,000 assistant messages per month, 50 projects, 15 seats, 50,000 knowledge tokens, custom domains, and branding removal. Pricing starts at $499/month, or $4,990 per year on annual billing (roughly $415/month with the 2-month discount). If you need tailored security, procurement, or higher limits beyond that, reach out for Enterprise.
How does the 14-day trial work?
Every new organization starts on the Trial plan for 14 days. During the trial you can use up to 250 assistant messages, launch 1 project on a branded *.diaform.io subdomain, and validate whether the workflow fits your team before moving to a paid plan.
How does Diaform count usage for billing?
For new workspaces, billing is based on assistant messages. Each time the AI sends a reply, one message is counted. Follow-up probes, retries, summaries, and longer conversations simply consume more assistant replies. Existing grandfathered workspaces may still remain on the older conversation-based model until they are migrated.
Do unused messages roll over each month?
Monthly message allowances reset on the first day of every billing cycle and do not roll over. This keeps forecasting simple and lets you right-size capacity, whether that means staying on Starter, moving up to Pro or Business, or reaching out for an Enterprise setup.
Can my team collaborate on the same workspace?
Yes. Starter includes 1 seats. Pro expands that to 5 seats, Business expands that to 15, and Enterprise can extend that further for larger teams.
What happens if I exceed my plan limits?
We notify you in-app and via email as you approach the quota. Messages already in flight will finish cleanly, and you can either upgrade immediately, schedule a higher plan with our team, or pause new links until the counter resets.
How does annual billing work, and how much do I save?
Starter, Pro, and Business can all be billed monthly or annually, and each card shows the effective monthly rate plus the annual total. Business annual billing is $4,990 per year, which works out to roughly $415/month with the 2-month discount. If you need a custom agreement beyond Business, reach out to hello@diaform.io.
How do knowledge uploads work across plans?
Starter and Pro let each project store up to 30,000 tokens of knowledge so follow-up questions stay grounded in your product facts. Business raises that to 50,000 tokens per project. If you need more than that, we can scope a higher-capacity Enterprise setup.
