Notes, tasks, projects and an AI that understands all of it. One system.
EngineerOS is an AI-native workspace that captures everything — notes, tasks, projects, and daily entries — in one connected system. It uses semantic search to find what you need, an AI assistant with citations to source notes, and a knowledge graph that reveals hidden connections. All data lives in your own Supabase project.

The model
Six objects. Every artifact.
EngineerOS is built on six core objects: User, Workspace, Project, Task, Note, and Daily Note. Everything else is derived from them, so nothing ever lives in a dead end.
Notes that read like documents
Markdown in, rendered pages out. Headings, code blocks, tables, and task lists all styled the way your docs deserve.
Architecture notes
{ supabase: "postgres" }
{ frontend: "next.js" }
Search everything with Cmd K
Notes, tasks, projects, and tags in one palette. Type, hit Enter, move on.
A kanban that keeps up
Drag cards between Backlog, Todo, In Progress, and Done. Positions persist, priorities stay visible.
BACKLOG

A daily note that shows up
One note per day, auto-created on first visit. Morning goals, journal, wins, and problems, in a fixed order.
Projects that hold it together
Tasks, notes, timeline, and resources under one roof, with progress you can see at a glance.
Capture before it evaporates
One dialog, two keystrokes. It becomes a note, a task, or sits in the inbox until you triage it.
Everything is linkable
Link a note to a task. File a note under a project. The graph is already there waiting for you.
Every note and task is indexed automatically. Ask questions in plain English, follow citations back to the source, and watch your knowledge graph grow as you write.
Semantic search, not just keywords
Ask in plain English. The index finds the right note even when you don't remember the exact words.
AI assistant with citations
Ask questions about your workspace and get grounded answers with links back to the exact notes they came from.
Knowledge graph
See how your notes connect via wikilinks and task links. Filter by project, drag nodes, and discover hidden relationships.
Automation rules
Recurring tasks create themselves. Quick captures auto-triage by keyword. Yesterday's unfinished work rolls over to today.
The board
One workspace. Zero context switching.
Every project, task, note, and daily entry lives in the same place. Drag a card, type a note, search across it all, and never re-open a tab to remember what you were doing.
