La Subtituleta is a FREE extension for Windows and Mac that transcribes Spanish with AI, translates your captions into many other languages, and puts them straight onto your Premiere timeline.
Free · No subscription · Bring your own API key
Acronyms, technical terms, regional slang and proper names. Fewer manual fixes.
Edit them the way you always have. With Reflow Lines, re-cut the lines for another format in seconds.
It identifies each speaker. Ideal for interviews, shows and multi-voice videos.
It generates data that Claude or ChatGPT can work with. For example, you can create motion graphics with the data La Subtituleta generates (video in Spanish).
You connect your own API, and every provider gives you free credit to get started. More than enough to subtitle a whole season. No credit card needed.

“…it works great, the number of corrections compared to Premiere's transcription drops enormously, and it manages to recognize all or almost all of the acronyms and concepts mentioned in the course, even with just one model connected…”
“…it understands Spanish much better, and what I like most is that the transcripts come out as JSON, because it's ideal for clipping with AI.”
“…it's very good, it solves exactly the issues I had with Premiere. What I liked most is the API options: they're varied and give enough credits. Thanks for sharing this app.”
“I tried La Subtituleta! It works wonderfully.”

Yes, La Subtituleta is free forever. What can cost money is the AI provider you pick, but they all give you free credit to start: roughly 200 to over 600 hours of audio with AssemblyAI, Speechmatics and Deepgram, and about 2.5 hours per month with ElevenLabs.
It's a password the AI provider gives you so La Subtituleta can send your audio to them and get the text back. You get it yourself, for free, by creating an account with the provider (usually your email or Google login is enough). It's a long code you copy and paste once into the extension's gear menu, and it stays on your computer. It's personal: don't share it with anyone, not even me.
Not to get started. No provider asks for one to get the API key and use the free credit. Later, if you run out of credit, they may ask for one (see below).
The credit from AssemblyAI, Speechmatics and Deepgram is a one-time starting credit per account and doesn't renew (ElevenLabs does, every month). When it's gone: AssemblyAI asks you to add funds or turn on billing, Speechmatics asks you to add a card and moves to pay-as-you-go, and Deepgram moves to pay-as-you-go. It costs roughly USD 0.20 to 0.40 per hour of audio. You never pay La Subtituleta anything.
Test it and measure it: transcribe a couple of videos, check how much credit you used in your provider's dashboard, and work out the cost per hour. If you use it every month, compare it to the hours you now spend fixing captions by hand. You can also spread the work across several providers.
Yes. You need Premiere Pro 2024 or later. The app isn't signed by Apple yet, so macOS will ask you for an extra confirmation (it's explained above, in the install section). If you try it, tell us your Premiere and macOS versions, and whether your Mac is Apple Silicon or Intel.
It works. La Subtituleta detects the video's language on its own and, if you want, translates the captions into many other languages (English, Portuguese, French, German, Italian, Japanese, Chinese, Korean and more).
The API detects when the speaker changes, but it can't know what each person is called. You enter the names in the order they appear (Speaker 1, Speaker 2…) and that information is stored in the JSON.
For now La Subtituleta is available for Premiere Pro, on Windows and Mac. Nico Russo wants to keep it that way: Premiere is the program he uses every day, and that's how he builds and improves it. The key is that tools should be made by the people who use them. If you use DaVinci and want to collaborate with Nico (testing, helping launch it and keep testing it from time to time), write to nico@nicorusso.com.
The most common error is “API 401: Invalid credentials”: it means the key isn't valid or belongs to a different provider. Delete it in Settings, save, paste a valid key again and check that the selected model belongs to the same service. Try again with a short video. If it keeps failing, write to us with the service and model you're using, and don't send your API key.
La Subtituleta has no servers of its own: it doesn't receive or store your audio. To transcribe, the audio goes straight from your computer to the AI provider you chose, and each provider has its own terms of use and confidentiality. If you work with confidential material or under an agreement with your client, read the provider's policies before uploading and use your own judgment.
So you don't spend hours fixing captions. It understands acronyms, regional slang and proper names, cuts lines the way an editor would, separates speakers and gives you a JSON to work with your AI. And you choose the engine.
Write to nico@nicorusso.com with a screenshot and the exact error text, your Premiere version and your operating system. Don't send your API key.
