Post to all social media at once, with one place to review

1. 01Write once. One caption (it becomes the YouTube description), one set of images or video.
2. 02Pick channels. Select any combination of your connected accounts.
3. 03Adjust per platform. Each platform has its own settings tab — Instagram, TikTok direct-post settings, YouTube privacy, LinkedIn visibility — so one post can behave correctly on four networks.
4. 04Choose when. Save a draft, schedule it for a date and time, or post now. Queued and drafted posts can be edited before publishing.
5. 05Watch the calendar. Week and month views show posts as colored cards by state — queued, draft, published, error. Click a card to edit it or see why it failed.

Per-platform variants through AI. The web composer defaults to one shared caption and media. Through AI Connect, an agent can create a different caption and media for each target in a single request.

Saving sources

Save from Instagram, TikTok, YouTube, LinkedIn and X through the iOS and Android share sheet or by pasting a public post link. Enriched saves include available captions, transcripts, summaries, hooks, on-screen text and format for later search. Free includes 100 lifetime enrichments; saved links and searches are unlimited.

AI agents

Claude, ChatGPT, Claude Code, Codex, Cursor, Windsurf, Raycast, Zed and any MCP-capable agent can search your saves, plan and schedule posts, and read analytics. See the Claude guide, the ChatGPT guide and the AI Connect docs.

Developer surfaces

MCP (19 tools), CLI and API, with OAuth sign-in or scoped keys. See /mcp, /cli, /api.

• Your inspiration lives next to your calendar. Save a Reel, search it later by meaning, and schedule a post built on it without switching apps.
• Analytics aren't trapped in each app. Compare accounts and rank posts across Instagram, TikTok, YouTube and X in one place; history windows are 7, 30 or 90 days by plan.
• Your AI can run the whole loop. The same integrations are available to Claude or ChatGPT: "schedule a week from my saved hooks" is one prompt.
• Review before scheduling. Every post shows on the calendar as draft, queued, published or failed, with the reason if it failed. Your AI confirms before publishing unless you've approved it in advance.

If you need Facebook, Pinterest, Threads or 30 networks, pick Buffer, Metricool or Postiz. If your posts start from videos you saved and you want your AI to handle the loop, FavStash fits.
