SeyloWho it's for
Seylo for copywriters
Copy goes through rounds: the brief, the first drafts, the notes back, the headline that finally landed. Seylo keeps every round in one project per client, with the approved version kept apart from the drafts.
What a client gathers
The brief, the product's own pages, the competitors' headlines, every draft and every note from the client. One project per client, a space per job, and the approved copy kept apart from the drafts, so the final version is always the one marked final.
Mark the line that matters
Highlight a sentence in a brief or a draft and it stays marked: the promise the client cares about, the phrase that has to survive every round. Anyone reading the project, your AI included, sees those lines first.
A swipe file that grows
Add to an existing note instead of starting a new one, from the browser or from the chat. One list of headlines that worked, kept in one place, rather than twenty scattered ones.
Your AI writes from the brief
Connect Claude or ChatGPT and they read the brief, the marked lines and the approved copy before they write a word. Ask for ten subject lines and they arrive in the project as drafts, linked to the brief they came from. Connecting your AI is part of Pro.
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.
