Toolglade’s take

A polished, mobile-first video tool for creators — great for captions, dubbing, and quick talking-head edits, less so for cinematic generation.

About Captions

Captions is an AI-powered video creation and editing app focused on talking-head and social content, offering auto-captions, editing, eye-contact correction, dubbing, and AI avatars.

Captions is an AI video studio built for creators making talking-head and social content. It automates the fiddly parts of short-form video — accurate animated captions, cutting filler words, eye-contact correction, background edits, translation and dubbing, and even fully AI-generated presenter avatars. It's available on mobile and desktop with a freemium model. Rather than competing with cinematic generators like Sora, Captions focuses on turning a phone recording (or a script) into polished, publish-ready social video quickly, which makes it popular with marketers and solo creators.

TL;DR

Captions (captions.ai) is an AI-powered video creation and editing platform offering automatic subtitles, AI avatars, dubbing, and expressive video generation through tools like Mirage Studio, AI Creator, and AI Twin. It targets creators, marketers, and businesses, with a free plan and paid tiers at $9.99/month (Pro), $24.99/month (Max), and $69.99/month (Scale), plus custom Enterprise pricing. It emphasizes mobile-first, AI-driven short-form video production.
