What it is
Fillout is a form, survey and quiz builder with deep database connections: it can read and update records in Airtable, Notion or Google Sheets, not just add new rows. It includes conditional logic, Stripe payments, appointment scheduling and signatures. The free plan is generous, and it fits teams that already run on no-code tools.
How to use it
- Connect your base in Airtable, Notion or Google Sheets and build forms that write to it.
- Update existing records with forms prefilled with each person's data.
- Take payments or bookings in the same form with Stripe and built-in scheduling.
- Build surveys and quizzes with conditional logic and pages.
- Send responses to your CRM, such as HubSpot.
What it's good for
- An agency using Airtable as its CRM that wants clients to update their own details.
- An online school that enrolls students, takes payment and books a welcome call in one flow.
- An ops team replacing Notion's native forms with one that has logic and validation.
Pros
- Reads and updates Airtable and Notion records, not just new rows
- Generous free plan with plenty of monthly responses
- Payments, scheduling and signatures inside the same form
Cons
- No Spanish-language interface
- Shines if you already use Airtable or Notion; simpler tools exist for standalone forms
- Removing branding or using a custom domain requires a paid plan
