Launch week: every idea card is free.Get Pro

SaaS ideas, mined from what people actually complain about.

Every idea comes from real Reddit posts, was researched against today's competitors, and survived an independent skeptic before it made the list.

Lost Notes in Notion

Users struggle to quickly capture, organize, sync, and retrieve information in Notion and similar knowledge tools, causing lost notes and broken workflows.

In their words

Vorrei un sistema che riesca a comprendere il contenuto del vault nel suo insieme.

r/IA_Italia on Reddit

has anyone found a reliable way to get .enex files into Notion without losing notes or pulling your hair out?

r/Notion on Reddit

I have a Notion system I built for my work that I have been using. I just want to turn that into an app and automate my process.

r/codex on Reddit

The failure mode isn't that the model writes badly. It's that nothing sits between the model and the filesystem.

r/ObsidianMD on Reddit

A run touches 10+ files and I'm left opening each one to check it didn't mangle anything.

r/ObsidianMD on Reddit

I haven't really found a good solution that lets me have a realtime CRDT-style sync that has the same permission system as Linux does for users.

r/selfhosted on Reddit

if something goes wrong, the native version history is a mess to dig through for specific database rows

r/Notion on Reddit

It turned into a chaotic internal wiki because nobody maintains the structure.

In practice it's been cumbersome to set up, and weeks in we're still not at the point of actually using it day-to-day.

r/LLMDevs on Reddit

Also a heavy obsidian user and use cc for vault management and essentially a custom search and insight into my notes and writing project (2 books, no ai writing, but help organizing).

r/hermesagent on Reddit

give it transcribed text --> it summarizes it --> stores it in a way that later queries can easily find this information

r/ClaudeCode on Reddit

Not being able to use Claude or codex anymore to write or update pages is a real deal breaker for me.

Hacker News

plain markdown in folders works great at 20 files and turns into its own kind of clutter at 500

Notion and PKM users

Where they talk

  • r/Notion
  • r/ObsidianMD
  • r/ClaudeCode
  • r/SaaS
  • r/SideProject
  • r/PKMS
  • r/LLMDevs
  • r/hermesagent

Tools they use today

  • Notion
  • Obsidian
  • Claude
  • Claude Code
  • Codex
  • OneNote
  • Claude Cowork
  • Logseq

Why those fall short

  • Electron renderers never idle; rich content and sync keep repainting
  • information ends up scattered everywhere, sorting through it becomes overwhelming
  • Logseq DB alpha lacks features; Obsidian has no native database file support
  • Notion mobile is fiddly; separate apps require mental syncing
  • Requires a community plugin for everything and still does not look nice
