a notebook for software engineers

Remember the work that made you better.

Decisions, incidents, trade-offs, the things you shipped and what you learned from them. Captured as they happen and kept as a memory you can draw on for interviews, reviews and reflection.

The timeline: every experience, newest first, with drafts waiting for review.

One entrybecomes a few structured experiences, not a pile of notes.

Every answercites the experiences it was built from.

No audiois kept after transcription, in the browser or on the server.

How it works

01

Capture it while it's fresh

Write a few lines or record a voice memo after the meeting, the incident, the launch. The raw entry is kept exactly as you said it, and audio is never stored.

A new entry. Voice notes are transcribed for you to correct before saving.

02

Review what it becomes

Suggested experiences come back structured: the problem, what you decided, the alternatives, the result. Nothing counts until you confirm it, and your edits are never overwritten.

A confirmed experience, read like a short article.

03

Ask when it matters

Before an interview or a review, ask a question and get a short answer built only from what you confirmed, with numbered sources you can open.

An answer with its sources. Loosely related experiences are listed apart and never used.

“Instead of adding a dedicated broker, I proposed running the queue in Postgres, which we already operated. We haven't lost a job in six months.”

What it's for

Interviews

Have three real stories ready for “tell me about a time you…” instead of the one you remember under pressure.

Performance reviews

Write your self review from a year of evidence, not the last two weeks.

Promotion cases

Show scope and impact with dates, projects and results your manager can check.

One-on-ones

Bring the decision you made last month and what came of it.

Your memory, on your terms

Nothing counts until you confirm it

AI drafts stay drafts. Refinements only fill empty fields, and confirmed memories get proposals, never silent edits.

Grounded, with citations

Answers cite the experiences they come from. When nothing fits, it says so instead of stretching.

Audio is never stored

Recordings are transcribed and discarded. You always review the transcript before it becomes an entry.

Delete means delete

Removing a memory also removes what was derived from it, including past answers that quoted it.

The best time to write it down is today.

Future you will thank you for it, in the next interview and the next review.
