## What is ergosum?

Ergosum is your second brain. Write notes the way you would in Notion — and an AI memory layer remembers everything, so your knowledge is always one question away.

Notes that become memory                                                                                                                 
Write in a clean block editor — text, bullets, todos, markdown. Every page you create joins your personal knowledge base.
                                                                                                                                            
AI that actually remembers you                                
Most AI chats forget the moment you close them. Ergosum's AI carries context across every conversation — it knows what you've written,   
what you're working on, and what you've decided. Ask "what did I think about X last month?" and get an answer.                           
                                                                                                                                         
Recall, not search                                                                                                                       
Stop hunting through folders. Ask in plain language and get back the exact note, idea, or decision you're looking for.
                                                                                                                                          
Structured when you want it, fluid when you don't                                                                                        
Nested pages, workspaces, private and shared spaces. Use it like Notion when you need structure. Let the AI do the organizing when you   
don't.                                                                                                                                  
                                                                                                                                         
Built for thinkers                                                                                                                       
Students, founders, researchers, writers — anyone whose work lives in their notes. Light, dark, and Catppuccin themes. Page history. 
Sharing.                                                                                                                                 
  
Cogito, ergo sum. Your thoughts, remembered.
