Everything your
project becomes.

Your notes, files, references and AI conversations. One place to keep your project moving.

Start your projectSee Seylo in action

Every reference.Every decision.One project.

Kept together, so the work does not have to be reassembled every time you come back to it.

Not forty chats and a desktop full of screenshots.

Every answer, file and image you save lands in the project it belongs to.

Save it from the page you’re on.

Select a passage on any page, right-click an image you found, or take a screenshot of what is on screen. The Seylo browser extension files it into the project and space you choose, without leaving the tab.

Add to ChromeWorks in Chrome, Edge, Brave and Arc

Save it on your phone.

Share from TikTok, Pinterest, YouTube, Safari or any other app, pick Seylo, and it goes into the right folder of your project.

No Drive folder, no download, no upload. It is in the project on every screen, and your assistant reads it over MCP.Seylo for iPhone is coming to the App Store.

Save it from your AI.

Settle something with Claude and tell it to update the project. New work and new decisions go straight in. A change to something already settled waits for you.

Claude
Updating Studio website in Seylo

Done. The brainstorm is in Research and the courtyard is now part of the plan. The look was already settled, so I left the new one as a suggestion for you.

Then let your AI work with everything you collected.

Open ChatGPT, or any assistant you connect. It reads the whole project, the pictures from your phone and the pages from your browser included, and saves what it makes back into it.

ChatGPT
Reading Studio website in Seylo

Here is your week: seven posts, each built from something already in the project. I saved it to Seylo so every tool can pick it up from there.

  • TueThe courtyard at five in the afternoonfrom your phone photos
  • WedOne house, from sketch to wallsfrom your brief
  • and four more days

Your AI reads what you approved.

An assistant hands you five image prompts, or three headlines. Approve the ones that worked: two of them, or all five. Every tool you connect is handed those as the ones the project signed off, with the rest kept separate as work in progress.

Exterior image prompt5 from ChatGPT

  • 1A low-rise home at dusk, windows lit from inside.
  • 2Close crop of the limestone wall and oak door in morning light.
  • 3Wide shot from the garden, long shadows.
  • 4The terrace on a grey day, one chair pulled out.
  • 5The facade in rain, reflections on the stone.

Until you approve them, every connected tool sees five drafts and no answer.

Find it again.

Search by what you mean, not the exact words. Each result comes back with its space and where it came from.

Whatever you’re making, it gets a project.

A dissertation, a launch, a seed round or a codebase: its sources, drafts and decisions sit together in one place, and every AI tool you connect reads the same project.

A few things to know.

  • Connected AI tools can read a project, create the spaces work is filed into, save new material into a space and rewrite existing content in place, and the previous version is kept. They cannot move something you already saved into another space, and they cannot confirm a decision. You do that.

  • No. Keep your notes, files and references in Seylo on their own. Connect AI tools when they help with your work.

  • Save passages, images and screenshots from any page with the browser extension, or add files directly. Choose the project each one belongs to. An iPhone app for saving from your phone is on its way.

  • Use supported tools such as Claude, ChatGPT and Cursor with your Seylo projects. Follow the connection instructions for the tool you use.

  • Pro adds AI connections, search by meaning and higher limits. The plan comparison shows what's included.
