Richer service experiences,
with an avatar that talks.

Examples
Use cases
01
Whistleblowing intake
The avatar asks in order; the reporter just answers
For an anonymous reporter, a face is easier to talk to than a blank form. Intake never stops, even at night.
Question 2 of 6
Roughly when did this happen, as far as you know?
02
Customer support desk
The same answer, spoken with a face
Your chatbot keeps generating the answers. A face on screen makes the wait feel shorter.
03
First-round interviews
The avatar reads each question; the candidate answers
Changing the questions is just editing a script. Interviewers stay out of first-round screening.
2:00 left
Tell us about the hardest piece of work you have done and how you got through it.
04
Digital signage
A voice on the store or facility screen with today’s guidance
Change the message without re-shooting. It can speak what matters right now: congestion, today’s notice, the next event.

05
Reception and visitor guidance
The person on screen asks and guides them through
Change the script and the reception changes. Other languages use the same avatar.

- Internal consultation desk
- The avatar listens and hands the gist to HR
- Harassment or evaluation concerns are easier to raise with a face that is not a person.
- Internal FAQ and help desk
- The answer you already have, read aloud
- Answer generation stays as it is. avacast only takes the "read it aloud" part.
- Training and e-learning
- Rewrite the script and the video is new on the spot
- No filming or editing to order for every revision.
How it works
How to get started
- 01
Sign up
Sign up with Google or email and issue a key in the console right away.
- 02
Integrate with your site
Use the API key on your server and receive a short-lived token for the browser. The API key never reaches the browser.
- 03
Add the conversation
Hand the token to the SDK and video arrives over WebRTC. Then just send the text you want spoken.
- Drops into any website
- Load one script and point it at an element. Your server makes a single API call.
- Pick an avatar
- Nine presets of different genders and ages. The voice changes to match the avatar.
- 9 languages
- Japanese, English, Chinese, Thai, Spanish, Vietnamese, Portuguese, Italian and Slovak. The same avatar speaks them all.

How we handle your data
Spoken text is never used for training
We keep the character and second counts needed for billing and delete the text after a retention period. Designed for sensitive content such as whistleblowing.

We measure the time from opening a session to closing it, per second, and sum it monthly. How many sessions are open at once is not billed by itself.
Only the excess is billed by usage and added to that month’s invoice. The rate differs by plan and is lower on higher plans.
No. avacast only speaks the text you send. Keep using whatever you already have for generating answers and recognizing speech.
No. You can set a monthly cap on connected minutes; once reached, the API returns 402 and nothing more is billed.
