¿Por qué confiar en esta guía?
I’ve used Captions AI for eight months and tested every feature covered here.
This tutorial comes from real projects — not marketing copy or vendor screenshots.
Captions AI is one of the most popular AI video editing apps available today.
But most people only ever touch auto-captions and stop there.
Captions make videos more engaging for viewers watching with the sound off.
Creating a finished clip here takes minutes, not an afternoon.
This guide shows you how to use Captions AI end to end.
Paso a paso, con capturas de pantalla y consejos profesionales.
Tutorial de IA para subtítulos
This How to Use Captions AI tutorial walks through every feature in order.
It starts at your first upload and ends at export.
Subtítulos AI
Record, edit, and caption video in one app. Captions AI writes your subtitles, cuts the filler words, and translates clips into multiple languages. Start free — no editing experience needed.

Here’s what the app looked like on my first project:

Ingresa tu email y elige una contraseña.
✓ Control: A confirmation message lands in your bandeja de entrada.

Captions AI runs on iOS, Android, and any desktop browser.
Install the mobile app if you film on your phone.
Log in, and the dashboard opens on the projects page.

Paso 3: Completar la configuración inicial
Pick your main language and your usual video format.
Then set your default caption style in settings.
✅ Hecho: Estás listo para usar cualquiera de las funciones a continuación.
How to Use Captions AI Creators
Creadores de IA lets you turn a script into a finished video using a stock presenter.
Aquí te mostramos cómo usarlo paso a paso.
Step 1: Open the Creators tab
Hacer clic Creadores de IA on the left of the dashboard.
You will see a grid of licensed presenters on screen.
Step 2: Pick a creator and paste your script
Choose a face that fits your audience and your business.
Paste your script into the text box, then select a language.
Así es como se ve:
✓ Control: The preview updates with your changes.
Paso 3: Generar y revisar
Hacer clic Generar and wait while the audio is processed.
Watch the draft, then trim any line that runs long.
✅ Resultado: A finished talking-head video with auto-captions burned in.
💡 Consejo profesional: Write in short sentences. The AI handles pacing better, and the captions stay under 40 characters per line.
How to Use Captions AI Shorts
Pantalones cortos de IA lets you cut one long recording into several short clips ready to post.
Aquí te mostramos cómo usarlo paso a paso.
Step 1: Upload your long video
Hacer clic Upload and select a file from your computer.
A podcast, seminario web, or interview recording all work here.
Step 2: Let the AI find the hooks
The tool scans your audio and ranks the strongest moments.
Each suggested clip gets a score and a draft caption.
Así es como se ve:
✓ Control: The preview updates with your changes.
Step 3: Export the clips you want
Select your favourites, then export each one as a separate file.
✅ Resultado: Five to ten vertical clips sized for a YouTube channel or feed.
💡 Consejo profesional: Check the first three seconds of every clip. A clean hook matters more than the rest of the edit.
How to Use Captions AI Editor
Edición de IA lets you edit video by deleting words from the transcript.
Aquí te mostramos cómo usarlo paso a paso.
Step 1: Open the transcript panel
Haga clic en el Transcripción icon beside your project.
Every spoken word appears as editable text.
Step 2: Delete the words you do not want

Correct any name or jargon the AI misheard.
The caption on screen updates as you type.
✅ Resultado: An edited cut with no gaps, silences, or stray “um” moments.

Aquí te mostramos cómo usarlo paso a paso.
Step 1: Record your training clip
Start by following the on-screen prompts and reading the sample text aloud.

✓ Control: The preview updates with your changes.
Step 3: Type a script and generate
Paste new text and your twin says it in your own voice.

Step 3: Save it as a preset
Name the style and save it for your next project.

Aquí te mostramos cómo usarlo paso a paso.
Step 1: Open the audio panel
Select your clip, then click the audio tab.
Step 2: Enable noise removal
Toggle it on and let the file process for a few seconds.
Try playing the before and after to compare.
Así es como se ve:

Step 1: Import the video
Drop your file into a new project and wait for the transcript.

✓ Control: The preview updates with your changes.
Step 3: Translate and export

Extra languages expand your reach to viewers who never speak English.
✅ Resultado: Captions in multiple languages, plus a subtitle file for your YouTube channel.
💡 Consejo profesional: Export an SRT alongside the burned-in version. YouTube reads that file as closed captions and indexes the text.
Consejos y atajos profesionales de IA para subtítulos
After eight months with Captions AI, these are the habits that saved me the most time.
They help you work far more efficiently on every project.
Atajos de teclado
| Acción | Atajo |
|---|---|
| Play or pause the preview | Espacio |
| Split the clip at the playhead | Cmd / Ctrl + B |
| Undo the last edit | Cmd / Ctrl + Z |
| Export the current project | Cmd / Ctrl + E |
These shortcuts alone cut my editing time roughly in half.
For example, splitting a clip by hand costs three separate clicks.
Características ocultas que la mayoría de la gente pasa por alto
- Espacios de trabajo: Keep client projects in separate workspaces so brand presets never mix.
- Keyword emphasis: Bold one or two words per caption to hold attention on small screens.
- Batch translate: Generate the same video in several languages before you publish anything.
- Notas del orador: Paste your notes into the script field and the teleprompter reads them back.
Here are the benefits that show up fastest in real work:
Errores comunes que debe evitar la IA de subtítulos
Mistake #1: Publishing captions without reading them
❌ Incorrecto: Trusting the first pass and posting straight to your YouTube channel.
✅ Derecha: Treat AI captions as a first draft. Fix names, jargon, and punctuation before you publish.
Mistake #2: Cramming too much text on screen
❌ Incorrecto: Four lines of tiny text sitting over busy graphics.
✅ Derecha: One or two lines, 37 to 40 characters each, in high-contrast colors.
Mistake #3: Ignoring the accessibility side
❌ Incorrecto: Burning in captions only, so no subtitle file ever reaches viewers.
✅ Derecha: Export an SRT too. Closed captions meet WCAG 2.1 and make videos accessible to more people.
Solución de problemas de IA para subtítulos
Problem: Captions are out of sync with the audio
Causa: The timeline shifted after you trimmed a clip.
Arreglar: Open the transcript, select the caption, and drag its edge back onto the spoken line.
Problem: Names and technical words come out wrong
Causa: The AI misreads jargon, brand names, and strong accents.
Arreglar: Edit the text directly, then add repeat offenders to your custom dictionary.
Problem: Export fails or the file will not upload
Causa: The project is too long for your plan, or the render was interrupted.
Arreglar: Trim the video, lower the resolution, and export again on a stable connection.
📌 Nota: If none of these help, contact Captions AI support from the settings page.
¿Qué es Captions AI?
Subtítulos AI is an app that records, edits, and captions your video in one place.
Think of it as a studio, an editor, and a subtitle escritor sharing the same screen.
The team ships a new feature most months, so check the release notes.
Mira este breve resumen:
Incluye estas características clave:
- Creadores de IA: Script-to-video with licensed presenters and voices
- Cortos de IA: Automatic clip finding for long-form recordings
- Edición de IA: Transcript-based editing that removes filler words
- Gemelos de IA: Face and voice cloning for text-to-video
- Personalización de vídeo: Caption styling, presets, and brand controls
- Generador de avatares con IA: Prompt-based custom avatars and voices
- Contacto visual con IA: Gaze correction for scripted recordings
- Eliminador de ruido de fondo: One-click noise and echo removal
- Subtítulos automáticos: Automatic captions, translation, and SRT export
AI captioning works in two passes.
First the app transcribes your audio into text, then it times each caption to the words.
One note on scope: this handles video, not still photos.
Image captioning in AI is a separate job, so use an image tool for that.
