About

Seylo

Read full description

Seylo is a workspace for everything a project gathers: the pictures and pages you found, the notes and prompts you wrote, the files, and what was decided. Open a project on your phone and keep working on it. SAVE FROM ANY APP Press Share and choose Seylo. A page in Safari, a pin, a video, a photo, a passage you selected: it goes into the project you pick. A page keeps its address, so you can open it again. TAKE IT OR WRITE IT Take a photo, choose some from Photos, paste a link or write a note, straight into a project or one of its spaces. KEEP WORKING ON IT Rewrite a note, approve a draft, move things between spaces, add pictures to a note, and save any picture to Photos. A LIBRARY OF WHAT WORKED Keep the references you reuse across projects in one Library, grouped by theme, and mark which ones worked and which did not. EVERYTHING REMEMBERS WHERE IT CAME FROM The prompt behind the picture, the brief behind the prompt. Seylo keeps the line between them, so a project explains itself later. THE SAME PROJECTS ON YOUR COMPUTER On seylo.co each project is a map you can lay out and share. Seylo works with a Seylo account.
