Preflight
Social scheduler that checks every post before it leaves
Preflight schedules one post to 12 networks (YouTube, TikTok, Instagram, Facebook, Threads, LinkedIn, Pinterest, Bluesky, Mastodon, Telegram, Discord, Tumblr) and checks it against each network's real rules first: text length counted the way the network counts it, file size, video length, ratios. Clients approve posts from a link, no account needed. REST API and an MCP server for Claude and ChatGPT on every plan, Free included.
Hi, I'm Adam, I built Preflight. I kept watching scheduled posts fail halfway through a list of networks: a Bluesky post over 300 graphemes, an Instagram picture in the wrong ratio, a TikTok video longer than the creator's account allows. The scheduler said "scheduled" and the network said no, usually at 3 a.m.
Preflight runs the same check in the composer, the REST API and the MCP server, using each network's real rules (counted the way the network counts), before anything is sent. It publishes to 12 networks, clients can approve posts from a link without an account, and Claude or ChatGPT can schedule through the MCP server on every plan, including Free.
Things you can try without signing up: the free tools (character counter, video checker, image compressor, aspect ratio checker) and the open dataset of network limits under CC BY 4.0. We also publish a dated tracker of rule changes on the networks, with sources.
I'd love to hear which network's rules have burned you most. I'll answer every comment today.
