Which AI video tools say anything about subtitles?
Four do. Descript exports SRT or VTT files, HeyGen returns SRT and VTT captions for translated videos, and Kapwing lets Pro users download an SRT. SceneMixer leaves captions off the video on purpose, so text is added at the platform. The other 24 say nothing. From 4 source pages, read 2026-09-25; no maker pays to be listed.

Inclusion rule. A tool is listed when its own documentation states what the question asks. Order. Tools in alphabetical order.
Subtitle files keep text out of the picture, so it can be switched on, corrected and translated without a new render.
Burned-in captions are the alternative, and they freeze one language into the file; that is the reason SceneMixer gives for leaving them off.
