Sintra Studio Review
Script-first AI voice studio: you write the script, it voices it
Verdict: Sintra Studio suits people who write their own scripts and want a simple, podcast-shaped editor and a free allowance that does not expire. Skip it if you need voice cloning, music in the export, direct publishing to podcast apps or episodes written for you.

What Sintra Studio Is
Sintra Studio (sintrastudio.com) is a browser-based AI voice studio for scripted podcasts and YouTube narration. You write the script, mark who is speaking, give each speaker a voice, and export an MP3. It is the opposite of tools that write the episode for you: the words stay yours.
The editor works line by line with a timeline. You assign one voice per speaker, add timed pauses and preview music, and you can regenerate a single line; lines you have not changed cost no credits. Credits are metered per character, and Sintra Studio's own conversion puts about 1,500 words at about 10 minutes of audio, so the 10,000 free credits cover roughly one short episode. Exports are loudness-normalized MP3 with selectable bitrate and mono or stereo, and they contain the voices only: add music in a separate editor and upload the finished file to your podcast host, whose RSS feed then reaches Spotify and Apple Podcasts. Free voices are offered in English and five other languages. The product is in public beta, and its site states that it has no customer roster or testimonials yet; its trust page lists synthetic-voice disclosure, user ownership of content and GDPR.

API access is listed for Enterprise only. Sintra Studio does not publish a Pro price, so we cannot state a cost per finished minute for paid plans. Whether the free plan allows commercial use is not stated on the pages we reviewed; check Sintra Studio's terms before publishing for revenue.
Prices checked: October 5, 2026 on the vendor's pricing page.

Score Breakdown
Sintra Studio has no score yet. We only publish a score from a logged test under our scoring rubric, and we have not run the protocol on it. Until then it is not ranked against other tools.
Who Should Use It
Writers and solo creators who already have a script and want voiced audio without recording.
