03Studio

A script, not a text box.

Leelo splits what you paste into lines, one per speaker. Each speaker gets a voice, each line gets directed, and the timeline underneath is the mix you export.

Cast: As many speakers as the scene needs, each with their own voice.
Direct: Pace, emotion and emphasis line by line. Teach it how to say a name once.
Mix: Voices, music and sound effects on their own lanes, with levels you can hear.
Export: One file, loudness set for podcasts, audiobooks or broadcast.

06Dubbing

Same video. Same voice. Their language.

Upload a video or paste a link, pick the languages, and Leelo translates and re-voices it, keeping each speaker's own voice. Open the result in the Studio to adjust any line.

In: A video or audio file, or a link to one.
Out: The dubbed video, the audio alone, and an editable script per language.
Cost: Paid in the same credits as everything else, with the cost shown before you start. Failed dubs are refunded.

11Questions

What people ask before they sign up.

Yes. Every account starts with 1,000 free credits, with no card needed. That's about 1,000 words, roughly seven minutes of narration in a standard voice, enough to try every tool. The free credits are given once, when you sign up, and don't renew. The free plan is for personal use; paid plans add commercial use, credits every month, more storage and files that are kept for longer.

One word read by a standard voice is one credit. Premium voices cost 1.5 credits a word and your own cloned or designed voices 5. Everything else is priced in the same credits: transcription 40 a minute, clean-up and the voice changer 1,300 a minute, and sound effects 20 a second. The app always shows the cost before you start anything expensive.

Yes, on any paid plan and on lifetime deals: videos, ads, courses, podcasts, audiobooks, apps and products. Audio made on the free plan is for personal use.

Your own, or the voice of someone who has given you permission. Cloning asks you to confirm that consent every time, and cloning someone without it, or using a voice to impersonate or deceive, is against our terms and gets the voice removed.

Monthly credits don't: each month starts again at your plan's amount. Credit packs are different. They're bought once, spent after your monthly credits, and last 12 months.

Yes. Cancel from Billing in the app whenever you like. You keep your plan until the end of the period you've paid for; after that the account goes back to the free plan, or to your lifetime deal if you have one, with everything you've made.

Cloning always asks for the speaker's consent.
Commercial use on every paid plan.
Failed jobs give their credits back.
Payments by Stripe. We never see your card.
