Ultrathink is your
personal knowledge base
Capture every thought.
Organise the way you want.
Search and recall with natural language.
Ultrathink allows you to capture almost any type of information, and store it in your own personal private knowledge base. From notes, to links, files, audio, screenshots and more. Once stored you can augment, enhance, search, sort and order any way you wish.
Everything you need to capture knowledge
Capture knowledge and information with our browser extension, desktop widget, and mobile web app. Android and iOS native apps coming when people ask for them.
One-click capture from everywhere
Capture any part of a webpage or link, grab files and documents from your desktop, notes and thoughts, and anything on your phone.
Organise with the fluidity of thought
Ultrathink allows you to view and sort knowledge your way. Grids, Kanban boards, freeform canvas. Multiple ways to see and arrange your knowledge.
Customise projects, tasks and knowledge
Out of the box Ultrathink sorts your thoughts into distinct entities, but you can customise them to suit your way of working. In fact you can customise almost all aspects of the app.

"I made Ultrathink for myself, as an internal tool. But people quickly started asking me to let them try it out, and it snowballed from there."
"You can really shape Ultrathink to work the way you work. Strip it down and just collect links and notes. Or go full organised with your own projects and tasks."

"I have ADHD and this tool feels like it was made just for me. I like to write everything down, Ultrathink helps me do that. Then I just search and sort to pore over stuff."
