MyNotes for developers

A notebook with an API. Every script in your stack gets its own notebook; one curl per event; read all of them from your phone.

What MyNotes is — and isn't

MyNotes is the place to store digest outputs from your jobs — successful payments one after another, errors, failed deploys, daily summaries, AI session transcripts — anything you'd actually want to read on your phone. Raw firehose server output? Pipe it into a log aggregator (Datadog, BetterStack). MyNotes is the everyday highlights layer above that, plus any note you'd like to write by hand. Append-only mode protects accidental overwrites for log-style notes.

The pitch

Most notes apps want you to file things into a hierarchy. MyNotes' Dev tier inverts that for the engineering use case: the note is the channel. Closer to "Slack channels for bots" than "fancy notes app." A few examples of what people actually wire up:

claude-code — sublimate AI coding sessions via a slash command
cron-jobs-prod — hourly cron one-liner with the result
payments-product-X — Stripe webhook handler appends each event
failed-deploys — GitHub Action on red writes a one-liner
engineering-journal — shell alias j "fixed the auth bug"
agent-scratchpad — autonomous-agent working memory between runs

One curl, one event

Append by filename — no id lookup, no setup step, no per-bot Slack channel, no log aggregator to spin up:

curl -X POST https://mynotes.app/api/v1/notes/by-filename/cron-jobs-prod/append \
  -H "Authorization: Bearer $MYNOTES_API_TOKEN" \
  -d '{"text":"backup ok 2026-04-26 03:00"}'

The first call to a filename creates the note; every subsequent call appends a line. Idempotency keys protect against double-writes on retries. Bulk endpoints on the Dev-pro tier let you ship up to 50 notes per request. Full API docs at /docs.
