SeyloWho it's for
Seylo for founders
Before a launch ships it is spread over a dozen places: the brief in a doc, the screens in exports, the posts in a chat, the price in your head. Seylo puts the whole launch in one project, and every AI you use reads it from there.
What a launch gathers
The brief, the landing page copy, the posts for launch week, the screens, the competitor pages you studied and what early users told you. One project, a space for each, drawn as a map you can take in at a glance.
What you decided, written down once
Some things are settled: the price, the launch date, who it is for. Seylo keeps them as the project's state, one current value for each, with the older ones kept underneath. Change the price and every AI reading the project sees the new one. A suggestion that contradicts a decision waits for you instead of replacing it.
One context for Claude, ChatGPT and Cursor
Write the landing copy with Claude, the launch posts with ChatGPT, build the page in Cursor. All three read the same project, so the copy says the right price without being told and Cursor builds from the copy you approved. What they write comes back as drafts, linked to what it was made from. Connecting your AI is part of Pro.
Saved from wherever you are
A competitor's pricing page, a screenshot of an onboarding you liked, an answer from ChatGPT worth keeping: right-click it and choose Save to Seylo, or share it from your iPhone. It goes into the launch, not into a folder called Misc.
What it costs
Seylo is free for 3 active projects, with the Library and the browser extension included. Pro is $8.99 per month, billed annually, and is where connecting your AI tools and sharing a project live. The whole list is on the pricing page.
