Unsearchable Scattered Notes
People struggle to quickly capture, organize, and later retrieve notes that end up scattered, duplicated, and unsearchable across tools.
In their words
It's really restricting my ability to continue using RemNote for serious studying despite trying to ignore it
I would absolutely pay for a simple, fast outliner that finally nails this.
creation has to be instant, more than a second or two to jot a thought and I stop using it.
It takes too many non-intuitive clicks to move around and find what I'm looking for. This makes me lose flow.
not being able to pin pages to stay open would be my biggest pain point
I brought the app because I thought that the feature of "App-aware notes" can be easily edited while I work on the active window, and periodically glance at the gutter where I put the notes on. But it didn't.
You spend so much time maintaining the filing cabinet that you never actually use the information to build anything new.
sync that works across devices, hosted in the EU, nothing to self-host or configure
It is honestly pretty trash compared to what I think I could vibecode in a day or two and be far more useful for me.
open app → wait for sync → find the right database → new entry → wait for properties to load. By then the thought is gone.
opening the app, writing it done and closing it SORT OF throws me off the flow
future-me can't find it because (a) it's in one of five places and (b) I've already forgotten the exact word I used
every corporate laptop I've had for the last 10 years prohibits app store and icloud storage
Every blog post I publish started as a note in a different app, and the handoff is where the draft usually dies.

- RemNote
Why those fall short
- Maintaining the filing cabinet replaces actually using the information
- merge conflicts, forgetting to push, mobile no-go, babysitting a database
- mobile editor bugs, no WYSIWYG, too many containers, no real-time sync
- AI and team features clutter; Obsidian needs many extensions
- Still must decide which database/template before capturing; multiple databases break simple inbox
