COMPARISON
Tellfully vs TypelessForm
Both add voice to the form already on your website, and with both, the visitor checks the answers and presses your submit button. TypelessForm fills every field it can from one spoken sentence, at a low price per fill. Tellfully holds a short conversation that asks about missing details, which suits longer quote and inquiry forms.

At a glance
| Compared | TypelessForm | Tellfully |
|---|---|---|
| What it is | A voice widget that fills HTML form fields from one spoken sentence. Built by Webappski.[1] | An optional voice assistant for supported website forms. Visitors speak or type, answer follow-up questions and review the answers. |
| How the visitor uses it | Clicks a microphone button and speaks once. Every detected field fills in a single pass.[1] | Opens the assistant and explains what they need. The assistant asks about anything your form still needs, then shows the answers. |
| Missing details | Fills the fields the visitor mentioned. In TypelessForm’s own accuracy test, nothing was invented for fields nobody mentioned. We didn’t find a description of follow-up questions.[1] [4] | Asks a follow-up question about details your form still needs, before the visitor reviews. |
| Review and submit | The visitor reviews and edits the filled fields, then submits. The widget “doesn’t click or submit.”[1] [3] | The visitor reviews the answers, Tellfully fills your form, and the visitor uses your original submit button. Email addresses and phone numbers are confirmed on screen. |
| Your form and delivery | Works on your existing form with no backend changes.[1] | Works on your existing supported form. Its usual delivery stays in place. |
| Field types | TypelessForm’s pages differ. Its home page lists text, email, phone, date, select and textarea fields, and its AI-agents page adds checkboxes; Webappski’s product page says it fills text inputs and text areas only and skips dropdowns, checkboxes and radio buttons. It recommends forms of about 20 fields or fewer.[1] [2] [3] | Text, email, phone and number fields and text areas. Dropdowns, radio buttons and checkboxes when the choices match your form. File uploads, payments, signatures, passwords and consent checkboxes stay with the visitor. |
| Languages | 25 interface languages. Spoken input isn’t limited to them.[1] | You choose the conversation language, or let it follow the visitor. Test the language you need before visitors see it. |
| Voice processing | OpenAI models transcribe speech and map it to fields. TypelessForm says audio is discarded once the response returns and OpenAI doesn’t keep it; OpenAI keeps the transcript text, field descriptions and filled values for up to 30 days for abuse monitoring.[1] | Google Gemini processes live voice. Tellfully doesn’t offer audio recording. See our privacy notice. |
| Setup | Get an API key and add one script tag. Lists React, Vue, Angular, WordPress and plain HTML sites.[1] | Connect your form, test a conversation, publish, then add one snippet to the page with your form. Custom forms may need developer help. |
| Pricing | A free pilot of 200 form fills (one time, no card). Then €29, €99 or €199 a month for up to 800, 3,000 or 10,000 form fills (its site also calls them form submissions), on 5, 10 or 20 domains. Paid plans are billed by invoice.[1] [2] [3] | A free trial, with no card required and no automatic subscription. Pilot pricing is $49 per month; launch prices are still being finalized. See pricing. |
| Stated limits | Not built for health information, payment card data or government ID numbers, because audio goes to a US-based AI provider.[1] | Doesn’t support forms embedded from another service in an iframe, or Typeform, Tally, Fillout or Jotform forms. Doesn’t dispatch emergency help, and we don’t recommend it for medical or legal intake. See compatibility. |
What they have in common
Both add an optional voice step to a form you already have, so you don’t rebuild the form or change where submissions go. Neither submits the form for the visitor. Both let the visitor check and edit what was filled in, and both leave sensitive fields like passwords and card numbers alone.[1]
Where they differ
One sentence, or a short conversation
TypelessForm is built around a single spoken sentence: speak once, and the fields fill together.[1] That’s quick when a visitor knows what the form wants, like a name, an email and a date.
Tellfully expects the visitor to explain the request in their own words, then asks about what’s still missing. A homeowner might say “there’s a leak around our skylight,” and the assistant asks when it started or how old the roof is. That takes longer than one sentence. It’s meant for forms where the details matter to whoever follows up.
Checking contact details
Both include a review step. Tellfully adds one thing for email addresses and phone numbers: the visitor confirms them on screen, because a misheard character means nobody can reply. Agreeing out loud doesn’t count.
Price
TypelessForm’s plans start at €29 a month for up to 800 form fills, after a free 200-fill pilot.[1] Tellfully’s pilot pricing is $49 a month, and launch prices are still being finalized; see pricing. If your form is short and you expect many fills, compare the two on your own monthly volume.
