Verdict
Evidence: Editorial assessmentSintra Studio is a browser tool that reads a script you have written in AI voices and exports it as an MP3, for podcasts, YouTube narration and short intros. You assign a voice to each speaker and fix lines one at a time. It does not write scripts, clone voices or publish to Spotify. The free Starter plan gives 10,000 credits that do not expire. It is in public beta.
Not to be confused with Sintra AI (sintra.ai), an unrelated AI business-assistant product.

Who should use it
- Hosts who write every word of the episode before recording
- YouTube explainer channels that need narration under footage
- Podcast intros and stingers that must sound the same every week
- People who publish irregularly: free credits do not expire
Who should skip it
- You want AI to research and write the episode: try NotebookLM or Jellypod
- You need your own cloned voice: try ElevenLabs or Wondercraft
- You need music mixed into the final file (Wondercraft) or one-click distribution (Jellypod) today
How it works
You paste a script and mark who says each line, which works for solo shows, co-hosts and interviews. Each speaker gets a voice. When one sentence sounds wrong, you edit it and regenerate only that line, and unchanged lines are not charged again. The finished file is a single MP3 you upload to a podcast host or drop onto a video timeline.
Before signing up, you can test a voice on two sentences of your own text (male or female English voice; listening needs no account, downloading the MP3 needs a confirmed email).
For video, the same workflow produces narration to lay under footage; the provider describes this on its AI voice generator for YouTube page. Check the commercial-use terms before monetizing (see Limitations).
How the free plan compares
Never-expiring free credits are unusual. ElevenLabs' free credits reset monthly, and Wondercraft's free plan is 150 credits with a watermark (both checked 5 Oct 2026). Because Sintra Studio's paid prices are not public, you cannot yet compare the cost of a weekly show with competitors'. See AI podcast generators compared.
Limitations and risks
- Commercial use on the free plan is not stated in the Terms (checked 5 Oct 2026). The provider lists a "commercial licence" among paid features. Confirm with the provider before monetizing free-plan audio.
- No public paid pricing: Pro and Enterprise are "Contact sales".
- Beta: no customer reviews or case studies exist yet, so voice quality and reliability claims rest on the provider. aixjo has not run its own audio test yet.
- Voice-only export: add music in your editor.
- No voice cloning and no direct publishing to podcast directories.
- Not verified by aixjo: voice quality, the list of supported languages (the provider says English and several other languages), and the Pro credit allotment.

Common questions
Is Sintra Studio the same as Sintra AI?
No. Sintra Studio (sintrastudio.com) makes audio from scripts. Sintra AI (sintra.ai) is a separate company offering AI business assistants.
Is Sintra Studio free?
There is a free Starter plan with 10,000 credits, no card required, and the credits do not expire. Pro and Enterprise are paid, with prices on request.
How long a podcast can I make for free?
About 10 minutes, by the provider's estimate: 10,000 characters is roughly 1,500 words at about 150 words per minute.
Does it write the script?
No. It voices the text you provide.
Can I clone my voice?
No, not as of 5 October 2026.
Can it publish to Spotify or Apple Podcasts?
Not directly. You upload the MP3 to a podcast host, and the host's RSS feed reaches the directories.
Do I have to disclose AI voices?
In most cases yes. YouTube, Apple Podcasts and Spotify all have rules on synthetic voices or impersonation. Check each platform's current policy before you publish.
