The AI trap
Most companies pick an AI model before they've structured their knowledge.
A model only knows what you give it. If decisions live in inboxes, notes in personal drives and tasks in five tools, even the best model answers from fragments.
The usual order
- Choose a model
- Point it at scattered files
- Get generic, unreliable answers
The 
order
- Structure knowledge in projects
- Plug in Spark AI — or your own model via MCP
- Get answers grounded in your work
5DAYS is the tool that structures your knowledge. The model comes second.
The 5days stack
Each layer builds on the last
Every note, task, document, project, and recording your team creates — organized into one system, not scattered across five.
Knowledge
Everything your team has ever decided, discussed, or documented — pulled together from every source.
Execution
Decisions turn into tasks. Tasks turn into outcomes. Every task links back to its origin.
Collaboration
The shared space where knowledge and execution meet the people who make them real.
Ask anything. It knows everything.
Spark AI sits on top of your knowledge and execution layers. Its agentic mode retrieves, reasons, and acts — using only your data.
An open ecosystem
A public API and an MCP server. Connect 5DAYS to the AI you already use — every request respects your project permissions, so knowledge stays protected.
“We've tested tons of tools (Notion, Drive, Monday..) but 5days is the first one that actually connects the dots. We use it every day, both internally and with clients. Meetings, docs, tasks, all in one place.”

“5DAYS has been a total game-changer for me. Right out of the gate I could stash everything: meeting notes, docs, to-dos, even my calendar, in one clean, distraction-free spot. I use it every single day.”
