AI Caption review
A web captioning tool with flexible styles and subtitle workflows, plus watermarked free exports.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
AI Caption is a browser-based tool for creators and small teams making social videos, tutorials, or product demos. It transcribes spoken audio, aligns captions to speech, and can render them into exported video. Its Basic and Dynamic styles, along with controls for position, shadow, font, weight, and color, suit creators who want to adjust caption appearance without leaving a web workflow. It supports vertical, square, and landscape footage; uploads can be up to 5GB, with duration limits tied to source resolution.
The caption workflow extends beyond rendered video. AI Caption provides browser-based SRT and VTT editing, conversion between those subtitle formats, and translation that preserves subtitle timing. Creators can choose from 21 Basic and 9 Dynamic presets, then export H.264 MP4 with captions burned into the picture. Project history and generation status help track work in progress. This combination makes it relevant for people who need both a publishable video and editable subtitle files; it is less suited to buyers looking for a broader editing suite or a product outside the web.
The Free plan includes 20 registration credits for testing caption quality, but exports on free accounts carry a watermark. Pro offers recurring credits and weekly creator exports, while Ultimate raises the credit allowance for high-volume publishing; both are available with monthly or yearly billing. One-time credit packs are another option for campaign bursts, and those credits do not expire. The pricing page does not provide numeric prices, so buyers should review the current offer before choosing a paid plan. Pick AI Caption for flexible caption styling and subtitle handling; consider alternatives if watermark-free free exports or a non-web platform are essential.
