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.

Forgotten Saved Content

People save articles, links, and media across scattered tools but can never find or revisit them later, so saved content becomes a forgotten pile.

In their words

Right now I am paying $22 / month between Recall, Raindrop, Notebook LM and Overcast to achieve all of this.

r/ProductivityApps on Reddit

Possibility for a setting to **enable offline caching** on all (or as much as possible) of the content on Karakeep, instead of selecting manually which ones to saves, would make me switch immediately!

r/selfhosted on Reddit

the core problem isn't storage, it's retrieval and actually acting on what you saved

r/SaaS on Reddit

I use newsreaders every day. When I find one I like paying even €10-20 is absolutely reasonable if I get what I need from it.

r/iOSProgramming on Reddit

I want to be able to check if I have the card on the app, then go get it within a few mins if I need it.

r/ManaBoxApp on Reddit

I want it to easily search my photos for "car" or "me" just like Apple or Google Photos does, but locally and privately.

r/hermesagent on Reddit

Most of them never get opened again. And when I do come back to them, I often can’t remember whether I already read them, why I saved them in the first place, or which project they were supposed to help with.

r/PKMS on Reddit

I'm starting to think the problem isn't the tools. It's the capture-to-retrieval gap.

r/PKMS on Reddit

RSS Viewer that creates an RSS feed from websites that don't offer RSS. This is a critical missing function for me

r/freesoftware on Reddit

any books we put up there get sun damaged so we don’t put product in the windows anymore

r/Barnesandnoble on Reddit

half the time I know I already wrote a great prompt for a specific task but can't find it when I need it

r/Entrepreneurs on Reddit

I’ve built a system to work around this, allowing me to filter words and patterns while ignoring the filter if an item comes from a certain URL or contains specific words or tags.

r/rss on Reddit

a personal auto-mark-as-read is absolutely essential

Hacker News

Almost all screenshots I take are in some way 'bookmarks' of something I want to read at a later stage. I often forget about them.

Knowledge workers and content savers

Where they talk

  • r/rss
  • r/PKMS
  • r/SideProject
  • r/chrome_extensions
  • r/selfhosted
  • r/ProductivityApps
  • r/Libraries
  • r/SaaS

Tools they use today

  • Notion
  • RSS
  • Goodreads
  • KOReader
  • Obsidian
  • Raindrop
  • Audiobookshelf
  • Instagram

Why those fall short

  • index must be redone by hand after every revision
  • no typo tolerance; feedback feature does not work
  • readers fire all feeds at once; no staggering or sequencing support
  • Each misses features; UI/UX complex and overwhelming
  • web view poor for mobile audiobooks; icons and theming limited; no two-way stats sync
