AI captions without watermark: what to check before you pay

What each tool says about watermarks

On most of the tools below, the watermark depends on which plan you are on. People who search for ai captions no watermark free usually want three things at once: no cost, clean video and correct words. A few tools below offer no cost and no watermark, but with tight limits, so decide which of the three you can give up.

Here is what each tool's own pages said about watermarks when we read them on 11 October 2026. We only list what the vendor wrote, and where a vendor's pages disagree with each other, we say so.

The 10-second test for any caption tool

Run this before you commit to a subscription or build a workflow around a tool. It takes about ten minutes.

1. Pick a 10-second stretch with a name, a number and fast talking, so the test covers the hard cases.
2. Export it with the plan, resolution and aspect ratio you will use for real, not the editor preview.
3. Play the file full screen on a phone, not in the editor preview.
4. Look at all four corners, then watch the last two seconds for an end card or outro. CapCut's own help page says template watermarks usually come from a default ending clip.
5. Read the captions against the audio, word by word. One missing not can reverse a sentence.
6. Check the file itself: is it 9:16 if you post to Shorts, Reels or TikTok, and does it open cleanly in the app you post from?

One more trap: a clip you downloaded on a free plan keeps its logo. Eklipse's help centre says old downloads keep the watermark unless you re-export, and Kapwing says a project exported with the watermark can be re-exported without it after you upgrade. Keep the project, not just the file.

No watermark is not the same as ready to post

W3C's accessibility guidance says automatically generated captions do not meet user needs unless someone confirms they are fully accurate, and that they usually need significant editing. It gives the example of a missing not making the captions contradict the audio. YouTube says the same about its own automatic captions: quality varies, so review and edit them.

So after the watermark test, read the whole clip once. Also decide whether you want the captions burned into the picture. The W3C describes open captions as always displayed and impossible to turn off. That suits short vertical video. If you want viewers to switch captions off, or you need a caption file, check that the tool exports one. VEED, Kapwing and Reap list SRT or VTT downloads on their pages.

Where KeyMo fits

KeyMo is built to cut long videos into vertical clips, not to caption a finished 30-second video. You give it a video of 5 minutes to 3 hours, up to 10 GB, by pasting a YouTube link or uploading an MP4 or MOV. It returns up to 15 clips at 1080x1920 and 30 fps, each captioned word by word in one of 12 styles, or with no captions. There is no watermark on any plan.

The honest limits: KeyMo has no free plan, so you cannot try it before paying. Starter is $12 a month for 300 source minutes and Pro is $29 a month for 900 (Rs 799 and Rs 1,999 for visitors in India). Link import fetches up to 1080p, and you confirm you own the video or have permission to use it. Details are on the pricing page.

If you have a podcast or interview to cut into captioned clips, KeyMo for podcast clips with no watermark is the closest fit. If you only need captions on a short video you already have, use one of the tools above, and compare their styles in our guide to the best auto captions apps.
