# Fourth Feed

> Fourth Feed is a directory of AI video tools (video generators, avatars and lip sync, editors, dubbing, lyric and music videos, faceless shorts, video model and data APIs) with pricing, free credits, traffic and agent-readiness (llms.txt, official MCP registry, public API), published as plain data for people and AI agents.

## How the data is made

- Only AI video tools are listed: tools that generate or edit video, and what you need to make one (video model APIs, video platform data APIs, voiceover, dubbing, music for video).
- A site is listed only if it has an llms.txt, or a home page with a title or meta description. Sites that block automated visitors are skipped.
- Summaries are written by Fourth Feed in its own words. Titles and descriptions marked "From the site" are shown as the site published them.
- Prices and free tiers are recorded only when the tool’s own page states them. Traffic and revenue name their source and month.
- Referral codes are our own; we get credits or a commission when they are used. A comparison that links to a product we make says so next to the link.
