In their own words
Captions
Captions is an AI video platform for creating and editing videos from footage or prompts. AI Edit can apply cuts, captions, music, and formatting to uploaded material. The service offers automatic transcription, more than 100 caption styles, and translation into over 100 languages. Users can dub videos into more than 30 languages with a cloned version of their voice. Prompt to Video creates talking-head videos from scripts using built-in actors or an AI Twin. The platform is aimed at creators, marketers, and developers making materials such as ads, listing videos, and podcast clips. Its Mirage API generates content from scripts, image references, or actor IDs and uses credit-based billing. The free plan costs nothing and includes no AI usage credits, one caption template, and basic editing tools. Max costs $24.99 a month and includes 500 monthly credits; Frontier plans provide higher credit allowances. Unused credits can roll over for up to two extra months, capped at three times the monthly allowance. Captions is available on Android, iOS, and web, with an API offering.
Diffusion Studio
Diffusion Studio is an AI video editor that pairs an infinite canvas with a timeline to organize connected scenes. It describes itself as an editor for agents and people, with edits written to a codebase that coding agents can read, change, and render. Controls cover timing, position, scale, layout, effects, audio mixing, filters, Bezier curves, spring easing, and motion presets. Agents can analyze footage, edit and animate scenes, generate video, images, audio, and sound effects, transcribe, localize, add captions, and export. The site lists integrations with Claude Code, Codex, Cursor, VS Code with Copilot, Antigravity, Gemini CLI, Devin (Windsurf), and other agents that support MCP. Every plan includes unlimited exports up to 4K without watermarks, and exports do not consume credits. The web editor, desktop app, dapi CLI, and skills are open source under MPL 2.0. It is available on web, Windows, macOS, Linux, and API. Free includes 50 one-time credits; Pro is $19 a month, billed annually, with 2,500 credits monthly.
