Notes · Tasks · Projects · Daily
Your work is already
connected.
Your tools aren’t.
EngineerOS keeps notes, tasks, projects, and daily entries in one indexed system. Ask a question in plain English and get an answer with citations back to the note it came from.
Free to start. Data lives in your own Supabase project.

The model
Six objects. Everything else is derived from them.
User, Workspace, Project, Task, Note, Daily Note. Nothing you write lands in a dead end, because there are no dead ends to land in.
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.

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.
The AI layer
Indexed as you write, so the answer knows where it came from.
Every note and task is embedded automatically. Ask in plain English, follow the citation back to the source note, and watch the graph fill in behind you.
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.
no black box
Most AI notes tools ask you to
trust the answer. This one shows its work.
Two features exist purely because a confident wrong answer is worse than no answer — and because you should never have to take either on faith.

ask as of a date
Pin a question to any past date and the assistant answers from your notes as they were written then. When a note changed since, the citation says so — and anything it can’t reconstruct is named, never quietly answered from today’s text.

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.
