SiliForm
An AI form builder that asks one question at a time in a conversational style, and can flag responses that look faked or AI-generated.

Description
Anyone who's run a survey or lead form knows the two problems that never go away: people abandon long forms, and some of the answers you do get aren't honest — or aren't even human. SiliForm tries to fix both by turning a form into a conversation, asking one question at a time and adapting the next one based on what you just answered, while quietly watching typing patterns and paste behavior to flag responses that look faked or AI-written.
Technically, you describe the form you want in plain language and SiliForm generates a conversational flow from it, with 48 built-in templates as a starting point. It supports voice input and resumable drafts, integrates for free with HubSpot, Zapier, Google Sheets, and webhooks, and the free plan genuinely allows unlimited forms and responses — quality scoring, AI-response detection, drop-off analytics, and UTM tracking are reserved for the $19/month Pro plan, which also includes a 14-day trial with no card required.
💬 Our review
The short version: SiliForm's real differentiator isn't the conversational format — plenty of form builders do that — it's the behavioral detection layer that tries to catch fake or AI-generated responses before they pollute your data, which is a genuinely new problem worth solving as AI-written form spam becomes more common.
The free plan is unusually generous for the category: unlimited forms and responses is more than Typeform or Jotform typically give away, which makes it easy to actually test the product before paying anything. The one-question-at-a-time format with dynamic follow-ups does tend to improve completion rates versus a wall of fields, and voice input is a nice touch for accessibility. The real gate is that the AI-detection feature — arguably the whole reason to pick SiliForm over Typeform — sits behind the Pro tier, so free users get the conversational UX but not the fraud-catching part that makes it distinctive. Worth it once fake or bot-driven form submissions are a measurable problem for you; if you just want a nicer-looking form, the free tiers of established players do that too.
