  1. 1. Infinall AI

    Captions in the AI Editor listen to a clip and add timed subtitles in one of six animated looks, run on your computer without uploading your audio, and use no credits. Infinall Chat writes post copy using your Brand Brain, and the Social Hub calendar counts caption characters for each platform and blocks scheduling until every platform fits. Transcribe turns an audio or video file of up to 50 MB into timed text and uses credits.

    Watch out: The AI Editor needs a laptop or desktop with a screen at least 1024 pixels wide, so you cannot caption videos on a phone. Connecting social accounts so posts publish by themselves is Pro only.

  2. 2. CapCut

    CapCut is a photo and video editor for web, desktop and mobile that adds automatic captions to videos in multiple languages. It has ready-made Reels and TikTok templates, and the mobile app exports up to 4K at 60fps.

    Watch out: App Store reviewers say features that used to be free keep moving behind the Pro paywall.

  3. 3. VEED

    VEED edits, subtitles, transcribes and translates video in the browser, with styled automatic subtitles and a brand kit for colours, fonts and logos. All paid plans include unlimited subtitle generation, subject to a fair use limit of 50 hours per month.

    Watch out: An App Store reviewer said auto captions missed words even when the speech in the clip was clear.

    4.8 on the App Store for the VEED Lite app from 19,975 ratings (checked 2026-10-29)

  4. 4. Captions

  5. 5. Later

    Watch out: A Google Play reviewer said the app failed to post to Instagram and lost the whole post.

  7. 7. Loomly

    Loomly generates captions, visuals and post variations tailored to each platform, ready to schedule. Starter covers 12 social accounts and 3 users with approval workflows and roles.

    Watch out: A Google Play reviewer said the mobile post editor has no auto-save and duplicates text while typing.

How to choose

Start by deciding which caption you need most. Subtitles burned into or attached to a video are made from speech, so the tool has to listen well and let you fix words quickly. Post captions are the text under an image or video, so the tool has to write in your brand voice and fit each platform's limit.

For video subtitles, test accuracy on your own footage, not a demo clip. Take one 60 second clip with real background noise, caption it in two tools, and count how many words you have to fix. Then check the export: VEED and CapCut work on many formats, and in the Infinall AI Editor captions become normal text clips you can restyle or retime.

For post captions, pick the tool where you already schedule. Writing in Later, SocialBee or Loomly saves copying text between apps. If you run several brands, check how the tool keeps each brand's voice: Infinall AI uses a saved Brand Brain per brand.

Then look at the bill. Per-seat and per-profile pricing grows fast for agencies. Count your seats, profiles and posts per month before you compare plans, and try the free plan or trial on a real week of posts.

What a social media manager needs from a caption generator

A manager writes and checks captions for several accounts every week, so the tool has to save repeated work, not add steps.

Accurate subtitles. Most short videos need on-screen captions. Check that names, product terms and numbers come out right, and that fixing a word is quick.

Brand voice. Post captions should sound like the brand, not like a template. Tools that store brand details, such as a brand kit in VEED or a Brand Brain in Infinall AI, cut down on rewrites.

Platform limits. Instagram allows a maximum of 2,200 characters in a caption. The Infinall calendar counts characters for each platform you pick, warns you when you go over and blocks scheduling until every platform fits. Use the free Instagram caption character counter to check a draft before you post.

Approvals. If a client or a manager signs off on every caption, Later Growth, Loomly and SocialBee Accelerate list approval workflows.

Free caption generator options compared

If budget is tight, these are the free routes:

  • Infinall AI: 1,000 credits every month with no card. Subtitles in the AI Editor run on your computer and use no credits, and importing an SRT or VTT file is free. The Let AI pick the look switch is a paid step and shows its price before you use it. Transcribe uses credits.
  • CapCut: free to try online with no credit card required.
  • VEED: free to start, with unlimited subtitle generation on paid plans.
  • Captions: a free version with basic trimming, transitions and some media library assets.
  • Later, SocialBee and Loomly: no free plan, but each offers a free trial.

For post captions specifically, Infinall Chat Auto replies are free with a fair use limit of 6 messages a minute, 60 an hour and 300 a day.

Captioning a video in Infinall AI

Open the AI Editor on a laptop or desktop and add a clip with speech in it. Turn on captions and pick one of six animated looks. The first time, the editor downloads a speech model of about 40 MB, which your browser keeps afterwards. Every caption becomes a text clip you can edit, restyle or move on the timeline. Export the video, which uses no credits, and add it to the Social Hub calendar with its post caption.

If you need a written transcript instead, for a blog post or show notes, use Transcribe on a file of up to 50 MB. Infinall AI is not the right pick if your team captions on phones: CapCut, VEED Lite or Captions fit that better.

Frequently asked questions

What is the best caption generator for videos?

For short vertical videos edited on a phone, CapCut adds automatic captions in multiple languages. VEED suits teams subtitling a lot of video in the browser. On a computer, the Infinall AI Editor makes timed subtitles for free, without uploading your audio.

Is there a free caption generator for video?

Yes. In the Infinall AI Editor, making subtitles from a clip uses no credits on the Free plan, and only the optional Let AI pick the look switch costs credits. CapCut and VEED are also free to start; check their pricing pages for what each free plan includes.

What is the best caption generator for Instagram posts?

If you schedule in Later, SocialBee or Loomly, use the AI caption writer built into that tool. If you want captions written from your saved brand details, Infinall Chat uses your Brand Brain, and the calendar checks each caption against the platform limit before scheduling.

Does Infinall AI post the captions for me?

It can. Posts on platforms with a connected account publish by themselves, and connecting accounts is a Pro feature. On Free you still plan and schedule the post, and Infinall sends you a reminder at the time.
