Why Trust This Guide

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.

Step by step, with screenshots and pro tips.

Step 1: Create Your Account

Go to the Captions AI website and click Sign Up.

Enter your email and choose a password.

✓ Checkpoint: A confirmation message lands in your inbox.

Step 2: Download or Access the App

Captions AI runs on iOS, Android, and any desktop browser.

Install the mobile app if you film on your phone.

✓ Checkpoint: You can see the Create button on screen.

Step 3: Complete Initial Setup

Pick your main language and your usual video format.

Then set your default caption style in settings.

✅ Done: You’re ready to use any feature below.

How to Use Captions AI Creators

AI Creators lets you turn a script into a finished video using a stock presenter.

Here’s how to use it step by step.

Step 1: Open the Creators tab

Click AI Creators 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.

Here’s what this looks like:

✓ Checkpoint: The preview updates with your changes.

Step 3: Generate and review

Click Generate and wait while the audio is processed.

Watch the draft, then trim any line that runs long.

✅ Result: A finished talking-head video with auto-captions burned in.

💡 Pro Tip: Write in short sentences. The AI handles pacing better, and the captions stay under 40 characters per line.

How to Use Captions AI Shorts

AI Shorts lets you cut one long recording into several short clips ready to post.

Here’s how to use it step by step.

Step 1: Upload your long video

Click Upload and select a file from your computer.

A podcast, webinar, 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.

Here’s what this looks like:

✓ Checkpoint: The preview updates with your changes.

Step 3: Export the clips you want

Select your favourites, then export each one as a separate file.

✅ Result: Five to ten vertical clips sized for a YouTube channel or feed.

💡 Pro Tip: 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

AI Edit lets you edit video by deleting words from the transcript.

Here’s how to use it step by step.

Step 1: Open the transcript panel

Click the Transcript icon beside your project.

Every spoken word appears as editable text.

Step 2: Delete the words you do not want

Clicking a word selects it instantly in the transcript.

Highlight a filler word, press delete, and the matching frames disappear.

Here’s what this looks like:

✓ Checkpoint: The preview updates with your changes.

Step 3: Fix the wording

Correct any name or jargon the AI misheard.

The caption on screen updates as you type.

✅ Result: An edited cut with no gaps, silences, or stray “um” moments.

💡 Pro Tip: Run a search for “um” and “like” first. Removing those two words alone tightens most recordings by 10%.

How to Use Captions AI Twins

AI Twins lets you clone your own face and voice so you can post without filming.

Here’s how to use it step by step.

Step 1: Record your training clip

Start by following the on-screen prompts and reading the sample text aloud.

Good lighting and clean audio decide how real the twin looks.

Step 2: Wait for training

Your clip is processed in the background, usually within a few hours.

You get a message when the twin is ready.

Here’s what this looks like:

✓ Checkpoint: 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.

✅ Result: A reusable digital twin that can create videos from text alone.

💡 Pro Tip: Record your training clip in the same location and lighting you normally film in. The twin blends into your other content.

How to Use Captions AI Video Customizer

Video Customization lets you control how every caption looks so your videos match your brand.

Here’s how to use it step by step.

Step 1: Open caption settings

Click any caption on the preview to open the style panel.

All the styling elements sit in one place: font, size, and position.

Step 2: Set font, color, and position

Pick a font, then choose high-contrast colors so text stays readable.

Drag the caption box away from platform graphics.

Check how captions display on a phone before you move on.

Here’s what this looks like:

✓ Checkpoint: The preview updates with your changes.

Step 3: Save it as a preset

Name the style and save it for your next project.

✅ Result: A saved caption preset you can apply to every future upload.

💡 Pro Tip: Keep captions to one or two lines. Anything longer forces viewers to read instead of watch.

How to Use Captions AI Avatar Generator

AI Avatar Generator lets you build a presenter from a prompt and stay off camera.

Here’s how to use it step by step.

Step 1: Open the avatar generator

Click Create, then choose the avatar option.

Step 2: Describe the presenter you want

Write the age, style, and setting in one line of detail.

The AI returns several options in about a minute.

Here’s what this looks like:

✓ Checkpoint: The preview updates with your changes.

Step 3: Attach a voice and script

Select a voice, paste your script, and generate the video.

✅ Result: An original presenter you can reuse across an entire content series.

💡 Pro Tip: Generate three avatars and test each on one post. Engagement tells you which face your audience trusts.

How to Use Captions AI Eye Contact

AI Eye Contact lets you fix your gaze so you appear to face the camera.

Here’s how to use it step by step.

Step 1: Upload the clip you read from notes

Any recording where your eyes drift off camera works.

Step 2: Turn on Eye Contact

Find the toggle in the effects panel and switch it on.

The preview shows the corrected gaze straight away.

✓ Checkpoint: The preview updates with your changes.

Step 3: Adjust the strength

Lower the slider if the effect looks too intense.

✅ Result: A clip where you appear to hold eye contact with viewers throughout.

💡 Pro Tip: Keep your head still while reading. The effect corrects your eyes, not large head movement.

How to Use Captions AI Background Noise Remover

Background Noise Remover lets you remove hum, traffic, and room echo in one click.

Here’s how to use it step by step.

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.

Here’s what this looks like:

✓ Checkpoint: The preview updates with your changes.

Step 3: Set the level

Dial it back if your voice starts to sound thin.

✅ Result: Clean audio that also lifts caption accuracy on the next pass.

💡 Pro Tip: Clean the audio before generating captions. The AI mishears far fewer words when the room noise is gone.

How to Use Captions AI Auto-Captions

Auto-Captions lets you add captions to any video automatically and translate them into other languages.

Here’s how to use it step by step.

Step 1: Import the video

Drop your file into a new project and wait for the transcript.

Adding captions this way takes seconds instead of an hour.

Step 2: Review the caption text

Read every line and fix spelling, names, and punctuation.

Check that each caption appears and leaves in time with the audio.

Here’s what this looks like:

✓ Checkpoint: The preview updates with your changes.

Step 3: Translate and export

Pick extra languages, then export burned-in captions or an SRT file.

Extra languages expand your reach to viewers who never speak English.

✅ Result: Captions in multiple languages, plus a subtitle file for your YouTube channel.

💡 Pro Tip: Export an SRT alongside the burned-in version. YouTube reads that file as closed captions and indexes the text.

Captions AI Pro Tips and Shortcuts

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.

Keyboard Shortcuts

Action	Shortcut
Play or pause the preview	Space
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.

Hidden Features Most People Miss

Workspaces: 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.
Speaker notes: Paste your notes into the script field and the teleprompter reads them back.

Here are the benefits that show up fastest in real work:

Captions AI Common Mistakes to Avoid

Mistake #1: Publishing captions without reading them

❌ Wrong: Trusting the first pass and posting straight to your YouTube channel.

✅ Right: Treat AI captions as a first draft. Fix names, jargon, and punctuation before you publish.

Mistake #2: Cramming too much text on screen

❌ Wrong: Four lines of tiny text sitting over busy graphics.

✅ Right: One or two lines, 37 to 40 characters each, in high-contrast colors.

Mistake #3: Ignoring the accessibility side

❌ Wrong: Burning in captions only, so no subtitle file ever reaches viewers.

✅ Right: Export an SRT too. Closed captions meet WCAG 2.1 and make videos accessible to more people.

Captions AI Troubleshooting

Problem: Captions are out of sync with the audio

Cause: The timeline shifted after you trimmed a clip.

Fix: Open the transcript, select the caption, and drag its edge back onto the spoken line.

Problem: Names and technical words come out wrong

Cause: The AI misreads jargon, brand names, and strong accents.

Fix: Edit the text directly, then add repeat offenders to your custom dictionary.

Problem: Export fails or the file will not upload

Cause: The project is too long for your plan, or the render was interrupted.

Fix: Trim the video, lower the resolution, and export again on a stable connection.

📌 Note: If none of these help, contact Captions AI support from the settings page.

What is Captions AI?

Captions 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 writer sharing the same screen.

The team ships a new feature most months, so check the release notes.

Watch this quick overview:

It includes these key features:

AI Creators: Script-to-video with licensed presenters and voices
AI Shorts: Automatic clip finding for long-form recordings
AI Edit: Transcript-based editing that removes filler words
AI Twins: Face and voice cloning for text-to-video
Video Customization: Caption styling, presets, and brand controls
AI Avatar Generator: Prompt-based custom avatars and voices
AI Eye Contact: Gaze correction for scripted recordings
Background Noise Remover: One-click noise and echo removal
Auto-Captions: 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.
