Two notes disagree about the rent you were quoted. Which one wins? Without dates, you are guessing. Without sources, you cannot tell a firsthand record from a rumor you pasted. Without the original audio, you cannot check whether the transcript misheard ‘fifteen’ as ‘fifty’. Provenance is what turns stored text into checkable memory.
A fact without a date cannot be ordered
Most real questions about your history are questions of sequence: what did I decide last, which quote came after the inspection, had I already been warned? Dates are what let a newer note supersede an older one. A system that displays content without chronology invites you to act on superseded information.
The source tells you how much to trust it
A thing you said in a voice memo, a screenshot of someone else’s claim, a forwarded link—these carry very different weight, and the difference is the source. Knowing that a note came from your own dictation versus a shared article changes what ‘my notes say X’ actually means.
Originals let you audit the machine
Transcription mishears names and numbers. Text extraction misreads photos. These errors are rare but land precisely on the details that matter most—figures, dates, medications. The original recording or image is your audit trail.
- Keep the original attached to every derived text, permanently.
- Mark uncertain transcription instead of guessing silently.
- Before acting on a number, a name, or a dosage—replay the source.
Answers inherit these requirements
When an assistant answers from your notes, the same three standards apply: the answer should show which notes it used, from when, and let you open each one. An answer that cannot show its provenance is an opinion about your memory, not a report of it.
When to actually verify against the source
Verification takes fifteen seconds and nobody does it habitually, so it needs a trigger rather than a virtue. Replay or reopen the original before acting whenever the answer contains:
- A number that will be spent, quoted, or committed to—prices, rates, quantities, dosages.
- A proper noun you will use in front of the person it belongs to.
- A date that determines whether something is late.
- A claim about what someone else agreed to, especially if it might be disputed.
- Anything transcribed in a noisy environment, where the error rate is highest exactly when you notice it least.
What provenance does not buy you
A date proves when a note was written, not when the event happened. Someone recording a conversation two days later produces a note whose timestamp is accurate and whose chronology is wrong, and no system can detect the difference. Where sequence genuinely matters, the note has to say when the thing occurred, not rely on its own metadata.
A source proves origin, not truth. A screenshot faithfully preserves a claim that may have been false when it was made, and knowing it came from a support chat tells you who said it—not whether they were right. Provenance narrows what you have to trust; it does not eliminate the judgment.
And keeping originals is not free. Audio and images are the bulk of any real archive, and an app that promises to keep every original forever is making a storage commitment worth checking before you rely on it. Ask what happens on the free tier, and whether export includes the media or only the text derived from it.
Store every memory with its birth certificate: a date, a source, and the untouched original. Verification you cannot do is trust you should not give.
