The honest answer

why the verdict is what it is

Writing and tagging is easy; the reason to build it is that plain Markdown on disk means you never have to migrate again. Sync is the only part to treat carefully.

What actually breaks

not "if". the specific failures.

  • Sync, which is the only genuinely hard part and the reason the paid tier exists
  • A file-sync service resolving a conflict by keeping both, so you accumulate 'note (conflicted copy)' files nobody merges
  • Search across thousands of notes, which is instant at a hundred and needs an index at ten thousand
  • Tags parsed from the text, where renaming a tag means rewriting every file that mentions it
  • Backlinks, which have to be indexed on write or recomputed on read, and neither is free at size
and then, at 3am

The honest failure is small and slow. You write on your laptop and your phone, syncing through a folder, and one afternoon both devices have an unsynced edit to the same note. The sync service does the sensible thing and keeps both, leaving a conflicted copy beside the original. You do not notice, because you were not looking at that note. Three months later there are nine of these, each holding a paragraph that exists nowhere else, and merging them is an evening of reading your own writing twice.

Is that you?

the verdict is a default, not a law

ship it if
  • Notes are Markdown files in a folder and the app is a view over them
  • Sync is a service you already trust, and conflicts are surfaced rather than hidden
  • It is yours, and the worst case is re-reading a duplicate
don’t ship it if
  • Notes live only in a database with no file representation
  • Conflicted copies are created silently and never surfaced
  • You are writing your own sync engine for this
  • Search is unindexed and the collection will grow past a few thousand

If you build it anyway

the checklist, then the prompt that enforces it

  1. Markdown files in a folder, one note per file. The format outliving the app is the entire reason this verdict is SHIP IT.
  2. Use an existing sync service rather than writing one, and actively detect conflicted copies so they surface instead of accumulating.
  3. Index for search on write. Scanning files works until it does not, and the transition is abrupt.
  4. Store tags in front matter rather than parsing them from prose, so renaming is a metadata change rather than a rewrite.
  5. Keep an append-only history or rely on version control, since a notes app is the only copy of thinking you cannot reconstruct.
  6. Make the app a view over the files, never the owner of them — anything you can only do in the app is a thing you lose with it.
the guardrail prompt
Before you build a Markdown notes app, apply these and push back if I ask you to break them.

1. Store one note per Markdown file in a plain folder, with metadata in front
   matter. Tell me this is why the project is safe: the format outlives the
   application, and the app is a view rather than an owner.
2. Do not write a sync engine. Use a file sync service I already have, and
   actively scan for conflicted copies — files matching the service's conflict
   naming pattern — and surface them prominently. Explain that these accumulate
   silently and each one holds writing that exists nowhere else.
3. Build a search index updated on write. Scanning files directly works for a
   few hundred notes and degrades sharply after that.
4. Put tags in front matter rather than parsing them from the body, so renaming
   a tag does not mean rewriting prose across many files.
5. Index backlinks on write, and define what happens when a link target is
   renamed or deleted.
6. Rely on git or an append-only history for versions. A notes collection is
   the one dataset I cannot reconstruct from anywhere else.
7. Never store anything in the database that is not also in the file. If a
   feature requires state the file cannot hold, tell me what I would lose by
   abandoning the app.
8. Out of scope unless I ask: real-time collaboration, publishing, encryption,
   mobile app, WYSIWYG editing.

their build prompt ↗

Or don’t build it

the boring option, and the way back out

just pay for it

$2.99 a month is essentially buying sync across Apple devices, which is the one hard part. If you have a sync service you already trust, building the editor over a folder of Markdown is one of the most durable projects on this list.

your exit plan, if you already built it

There is barely an exit to plan, which is the point — the notes are already Markdown files in a folder. Keep it that way and abandoning the app costs nothing but the view. Put the folder in version control and the history comes free.

Questions

Why are conflicted copies worse than a sync error?

Because they are silent and they look like success. The sync service did the safe thing — it kept both versions rather than choosing — but it filed the second one as a new file you have no reason to open. Errors get investigated; a spare file in a folder of hundreds does not, and the divergent paragraph sits there until you go looking.

Is one file per note really better than a database?

For notes specifically, yes, and it is why this entry is SHIP IT rather than DEMO ONLY. Plain files mean any editor opens them, version control works, sync services handle them, and abandoning your app costs nothing. A database gives you faster queries and takes the notes hostage — a poor trade for something you intend to keep for a decade.
