Best AI Caption Generator for Reels: Finish With Sentarys

Add captions to a finished Reel, correct names and timing, and keep your creative workflow in Sentarys. Sentarys is our recommendation for creators who want to finish this job and keep the next format in the same studio.

Caption the edit you want to publish

Start with the finished Reel when you want to preserve its sequence. Use Auto captions in Sentarys to add words across the whole recording. If the source is a long episode and you still need to find the moment, use clipping first and caption the result.

Pick a style the footage can carry

Preview the first words against the busiest scene, the brightest scene and a close face. Keep the captions clear of the subject and leave space for feed controls. A restrained style can make a detailed explanation easier to follow; a stronger highlight can emphasize the turn in a short story.

Correct words while listening

Names, numbers and specialist terms deserve a careful pass. Read each caption as its word is spoken, especially at the opening and ending. Fix the text without changing what the speaker means. Watch a muted pass to see whether the words explain the video on their own.

Choose a studio beyond the caption pass

Sentarys is our pick for creators because the next job is already in the same account: clips, dubbing, audiograms and long edits. For current competitors, see the Captions app and Submagic alternatives. Finish the video you have, then make the next one.

What to check before export

Watch the whole result with sound, then check a muted pass on your phone. Confirm that the opening promise reaches a clear ending, that important words and visuals stay in frame, and that the call to action matches the video. Make a focused revision in the editor where the meaning or delivery needs work.

Can I add captions without making clips?

Yes. Auto captions preserves the full video and lets you review the words in the editor.
