When an assistant answers from your own notes, the stakes are different from ordinary chatbot errors. A wrong answer here rewrites your past: a commitment you never made, a decision you actually reversed. Trust in a personal AI is not a feeling—it is a checklist, and it has four items.
Visible sources
Every claim should point to the notes that support it—openable, with dates and excerpts. Sources do more than prove the answer; they scope it. Seeing that a conclusion rests on two notes from January tells you what the system does not know as clearly as what it does.
Honest chronology
Personal history is full of reversals: plans changed, quotes revised, opinions updated. A trustworthy answer respects sequence—quoting the March decision means also surfacing the June note that overturned it. The most recent relevant evidence defines the current state; everything older should be presented as history.
Assumptions labeled as assumptions
Sometimes the notes do not fully answer the question, and a helpful system bridges the gap with inference. That is fine—if the seam is visible.
- ‘Your notes say X’ must mean the notes actually say X.
- ‘Probably Y, based on…’ marks inference doing the work.
- ‘Your notes do not cover this’ is a complete and honest answer.
- Conflicting evidence is shown as a conflict, not silently resolved.
Correctability that sticks
You will catch mistakes—a misattributed quote, a stale conclusion. Trust survives only if the correction has somewhere to go: fix the record, and future answers reflect the fix. An assistant that repeats an error you already corrected has demonstrated that verification is pointless—and verification is the entire basis of the relationship.
Before relying on any answer about your own history, run the checklist: can I see the sources, is the newest evidence on top, are guesses labeled, and will my correction stick? Four yeses make a memory. Anything less is a fluent guess.
