What SiliForm is
SiliForm is a web-based form builder for creating conversational forms and evaluating submissions for fake, rushed, duplicate, or AI-written input. Users can describe a form to generate a draft with fields and question flow. Forms can present one question at a time, rephrase questions based on earlier answers, accept voice input, and autosave. Free-text checks can flag invalid or irrelevant answers and invite respondents to try again. Pro adds question-level drop-off and geography analytics, UTM tracking, AI response summaries, and response quality scoring. The Free plan includes unlimited forms and responses, basic analytics, and 100 MB of storage, with file uploads limited to 10 MB each. Pro offers 10 GB storage and priority support. It costs $19 a year with annual billing or $29 a month with monthly billing. New accounts receive a 14-day Pro trial without a credit card, then move to Free automatically. Free lists HubSpot, Zapier, and webhook integrations; a lead-generation page also describes Google Sheets delivery. Webhook requests time out after five seconds, and failed deliveries are not automatically retried.
