About Biosai

Biosai is an AI coach for dating and relationships.

The site runs in English, German, Spanish and French and lets you start without paying, with a Premium subscription that unlocks unlimited coaching, photo evaluation and bio generation.

Editorial verdict

Pros & cons of Biosai

low confidence

Biosai covers more of the dating process than an opening-line generator: replies, reading signals, profile photos and first-date prep, by text or voice. It is cheap to try, but nobody is named behind it and Premium is billed in euros with a daily option, so check which interval you are signing up for.

Pros

  • Covers replies, mixed signals, profile photos, bios and first-date prep in one app
  • Voice coaching mode as well as text
  • Can be started without paying, with a free trial on Premium

Cons

  • No company name, founder or country found on the site or in its terms
  • Premium is priced in euros only, with daily and weekly intervals that cost far more over a month
  • Advice quality on sensitive relationship situations cannot be verified from the site

Best for

  • People wanting coaching across a whole dating interaction, not just opening messages
  • Users who would rather talk a situation through by voice than type

Not for

  • Anyone needing to confirm who runs the company before sharing private conversations
  • Users who want a fixed USD price shown up front

Watch out: The subscription screen offers daily, weekly, monthly and yearly billing; at EUR 1 a day the daily option costs double the EUR 15 monthly plan.
