Built for creators who write their own scripts
Sintra Studio is for YouTube creators who make explainers, tutorials, education, history and documentary, commentary and reviews. You do the research and the writing; the voice reads it. It isn’t built for churning out templated videos at volume, and YouTube’s monetization policies don’t reward that kind of channel anyway.
What you get
- Narration in minutes. Paste a script, pick a voice and generate. No booking a voice actor, no waiting for a recording slot.
- No microphone, no retakes. If a word comes out wrong, respell it and regenerate that one line.
- One consistent voice. Use the same narrator in every video, so your channel always sounds like itself.
- Ready for your editor. Export an MP3 and drop it on your video editor’s timeline.
Why you can trust what you hear
- Hear it before you sign up. The generator above reads your own words, free, with no account.
- A real voice library. The free plan includes our Free voices in English and five other languages. Premium voices from a licensed library come with the Pro plan.
- Your scripts stay yours. You keep ownership of everything you write.
- An honest beta. Sintra Studio is in public beta. We don’t have testimonials or customer logos yet, and we won’t invent them. Voice cloning isn’t available yet.
10,000 free credits, no card, no expiry
The Starter plan is free and includes 10,000 voice credits with no credit card. One credit is one character. Regenerating lines you haven’t changed costs nothing, and credits never expire, so there’s no monthly clock running on your free plan. See all plans.
What happens after you register
- 1. Confirm your email. Your 10,000 credits are added once your email address is verified.
- 2. Paste your script and pick a voice. Generate, listen, and regenerate any line that needs it.
- 3. Export and add it to your video. Download the MP3, place it in your editor, cut your visuals to it and upload.
Questions
- Do I need an account to try a voice?
- No. The generator on this page plays up to two sentences in an English male or female voice without signing up. Downloading that sample takes a confirmed email, and it’s meant for testing, not publishing. For full scripts and more voices, register free for the Starter plan.
- What do 10,000 free credits cover?
- One credit is one character of generated speech, spaces included. 10,000 credits cover about 1,500 words of script, roughly ten minutes of narration at 150 words per minute. Regenerating a line you haven’t changed is free, and credits never expire.
- Can I clone my own voice?
- Not yet. Voice cloning isn’t available in Sintra Studio today, so you pick a narrator from the voice library. Using the same library voice in every video still gives your channel one consistent sound.
- Does Sintra Studio sync narration to my video?
- No. Sintra Studio makes the narration audio. You export it as an MP3 and place it on your video editor’s timeline, then cut your footage to it.
