Captions is an editor where AI edits your video in a chosen style and adds a lot of new stuff to it. Dubl does something different: it builds the video only from what you said, using the takes you picked.
If you want music, sound effects, B-roll and transitions picked by AI. If you need translation and dubbing into other languages, AI avatars, eye contact correction, horizontal video, or editing on Android, in a browser or on a Mac. Captions simply does a lot more here.
If you shoot a talking head line by line, several takes of each, and want to quickly turn the best takes into a clean vertical video. The AI puts your lines in order by meaning, and only what you actually said makes it into the video.
| What we compare | Dubl | Captions |
|---|---|---|
| Pick the best of several takes | Takes of each line are grouped, the best one gets a star, switch in one tap | Not listed |
| A video made only of your takes | AI orders your lines by meaning; the draft uses only your takes and adds nothing of its own | AI Edit makes many edit decisions in the chosen style; manual edits are possible |
| Teleprompter | Yes, on iPhone | AI teleprompter |
| Auto captions | Yes | Animated styles, many languages |
| Cut pauses | Threshold from 0.3 to 5 seconds | Yes |
| Remove unwanted words | Tap a word in the transcript | Filler words removed automatically |
| Auto zoom | Smooth zoom-in on every line | AI Zoom |
| Cleaning noise from your voice | “Voice only”: the AI removes noise right on your phone | Yes |
| Music, sound effects, B-roll | No | Picked and generated by AI |
| Translation and dubbing, avatars, eye contact | No | Yes |
| Aspect ratios | Vertical only | Vertical and horizontal |
| Where it runs | iPhone; Android coming soon | iPhone, Android, web and Mac |
Captions is built around AI editing. You upload a video, pick a style in AI Edit, and the app places cuts, zooms, B-roll and sound for you. From there you can add captions, music, a translation into another language or even an AI avatar.
Dubl is simpler and more focused. You shoot your video line by line, several takes of each. AI transcribes your speech, groups the takes by line and puts a star on a strong one. It orders the lines by meaning, and all you do is pick takes. Nothing you didn't say will show up in the video.
If your video needs more than clean speech, Captions has a much wider toolkit:
Dubl has none of this — it's focused on building a talking video from your takes.
If you record one long take and are happy to let AI do the edit, Captions may be the better fit. If you shoot line by line and redo the ones that didn't land, that's exactly what Dubl is made for.
In Captions: upload a video → pick an AI Edit style → review what AI put together → tweak by hand, add captions, music or a translation → save.
In Dubl: record lines with the teleprompter or pick videos from your gallery → AI builds a draft from the best takes with pauses already cut → swap takes where you like and hide an extra line → tap away unwanted words, add stickers → save a vertical video.
Build the talking part in Dubl: pick the best takes, hide extra lines, cut pauses and unwanted words. Save the video to your gallery, then open it in Captions if you want to add music, sound effects, B-roll or a translation.

For talking videos shot in takes, yes — but it works differently. In Captions, AI edits the video in a chosen style and adds its own elements. Dubl builds the video only from your takes and orders the lines by meaning, adding nothing of its own.
No. Dubl has no music, sound effects, B-roll, translation or avatars — though “Voice only” removes noise from your voice. For those, it's easy to finish the video in another app.
This isn't listed on Captions' official pages. In Dubl it's the core idea: takes of each line sit together, and the best one has a star.
Dubl runs on iPhone right now, with Android coming soon. Captions is on iPhone, Android, web and Mac.
Get Dubl, shoot a couple of takes and see what comes out.
