Are After Effects Caption Plugins Free? What Free Tools Can Do and What You Pay For

Short answer: some are, most good ones aren't

After Effects has a big ecosystem. Some plugins and scripts are free, often made by a single developer in their spare time. Others are paid, usually as a one-off licence or a subscription. Caption tools sit in both camps.

The useful question isn't "is it free?" but "what do I need it to do?" If you caption one short video a month, a free workflow can be fine. If captions are part of every job, the hours add up quickly.

What you can do for free

Free transcription

Open-source speech recognition models, Whisper being the best known, can be run on your own computer at no cost. With some setup on the command line, they produce a transcript with timings, often as an SRT file. Many editing apps and video platforms also generate captions automatically, and most let you download them as SRT.

Free scripts that bring subtitles into After Effects

There are free scripts that read an SRT file and create text layers with the right in and out points. For clean, static subtitles this works. You get one layer per subtitle line, and you style it like any other text.

After Effects on its own

After Effects has excellent type tools: text animators, range selectors, expressions, effects. You can build any caption animation imaginable by hand. What it doesn't have is a built-in way to turn speech into timed captions, so the transcript has to come from somewhere else.

Where the free route runs out

• Word timing. Most free subtitle workflows give you timing per line, not per word. Word-by-word reveals and karaoke highlights need to know when each word is spoken. Without that, you're placing markers by ear.
• Animation per word. A subtitle line is one text layer. Making each word pop, bounce or change colour as it's spoken means splitting lines, setting keyframes and keeping everything in sync. On a one-minute clip that's around 150 words.
• Revisions. Change the font and every hand-built line has to be checked again.
• Setup and upkeep. Running a transcription model yourself means installing it, keeping it working after system updates and converting its output. A free script that stops working in the next After Effects version has nobody to fix it.

None of this makes free tools bad. They're honest about what they are. If static subtitles are all you need, a free SRT script is a perfectly good choice, and we'd tell a friend the same.

What you actually pay for in a caption plugin

1. Transcription that's built in

Cloud transcription costs real money to run, per minute of audio. That's why many caption tools sell credits or minutes. Local transcription costs nothing per minute, but someone has to package the model so it installs and runs without a terminal.

2. The animation system

This is the bulk of the work: turning a list of words and timings into layers that animate cleanly, re-space when fonts change and stay editable afterwards.

3. Styles

Good presets take a designer time to build and test with short words, long words and two-line phrases.

4. Maintenance

After Effects updates every year. Operating systems change. Transcription engines improve. A paid tool is partly a promise that it keeps working next year.

How Captyne prices it

We built Captyne as motion designers, so we priced it around how motion designers actually work. There's no free plan, but every plan starts with a 7-day free trial, so you can caption real projects before you pay anything.

• Starter, $9/month or $75/year. Unlimited offline transcription, your own OpenAI, Groq or AssemblyAI key, 5 minutes a month of Managed API transcription, 1 device.
• Individual Pro, $15/month or $126/year. 3 hours a month of Managed API, AI Decide and AI Stacking, full Marketplace access including buying and selling presets, 2 devices.
• Studio, $35/month or $294/year. 8 hours a month of Managed API, 5 devices.
• Enterprise. Contact us.

Paying yearly saves about 30%, and you can cancel any time.

Offline transcription is unlimited on every plan

This is the part we care about most. On every plan, including Starter, Offline / Local transcription runs Whisper Large v3.1 on your own computer with no minute limits, and your audio never leaves the machine. It needs supported hardware: an NVIDIA RTX 20-series or GTX 16-series card or newer on Windows, or an Apple silicon Mac. If your computer doesn't qualify, the Managed API works on any machine and uses your plan's minutes, or you can bring your own key and pay that provider directly.

Ways to spend nothing extra

• Already have subtitles? Import SRT / VTT turns them into animated captions without using any transcription minutes.
• Transcribed it before? Captions are saved with the project, and transcribing the same audio again with the same settings reuses the earlier result.
• Free presets. The Marketplace has free presets alongside paid ones, and you can always build your own.

A quick way to do the maths

Price is easier to judge against your own time than against other tools. Think about the last captioned video you made the free way. How long did the transcript take to clean up? How long did the timing and animation take? Then put a rough hourly rate on that time, even if it's only what you'd charge a client.

If captioning a short clip by hand takes you an afternoon, a monthly plan usually pays for itself on the first job. If you caption a couple of static subtitle files a year, it probably doesn't, and that's fine. There's no prize for paying for software you don't need.

Also count the hidden costs: the revision that means rebuilding lines, the client name you misheard, the script that broke after an update the week of a deadline.

So, free or paid?

Use a free workflow if you need static subtitles occasionally and don't mind some setup. Consider a paid plugin when captions are a weekly job, when you need word-level animation, or when a client revision shouldn't cost you an evening. Either way, try before you decide. That's what the trial is for.
