What is personal knowledge in Rio?
A document you wrote — a note, a spec, a people profile — in the same account as your tasks and calendar, so Rio can find a passage and use it in the next reply.
Why a second brain fails
Tools that only store text still leave you as the retrieval engine. You hunt for the note, then paste a chunk into chat. The useful shape: the same assistant that captures a task can locate the paragraph that said why the task exists.
Wiki vs working memory
| Personal wiki | Rio documents | |
|---|---|---|
| Written for | A future you who browses | A secretary who can search and open |
| Linked to work | If you remember to link | Same account as tasks and calendar |
| Edit from chat | Usually no | Proposed edits you accept — never silent overwrite of the whole doc |
| Best for | Long-lived reference | Context the next conversation needs |
Bottom line: keep a wiki if you like gardening pages. Use Rio when the next question should hit the note without you hunting.
How Rio uses what you wrote
Store it, find it, read a window — not the whole book.
- Store — notes and documents live in the database.
- Find — search is meaning plus text, so a vague question can still hit the right page.
- Read a window — Rio opens a bounded stretch of the doc. Size must never make a valid edit impossible.
Who this is for
For people who already write things down and then cannot find them when it is time to act.
