App Idea: A Personal Knowledge Management Tool That Organizes Notes by Intent
A capture tool that requires a quick 'what I'll use this for' tag at the moment of saving, so scattered notes and quotes stay retrievable and actionable.
How do you organize all the random things you learn?
I keep running into one problem where I save a lot of small bits of information, but later I can’t really find or use them. A line from a book, a good Reddit comment, something from a podcast, a work tip, a random idea I had during the day. It all feels useful at the moment, but then it ends up scattered across screenshots, notes, bookmarks, and memory. Recently, I’ve been trying a small change. Instead of saving things by where I found them, I try to save them by what I might use them for. Work ideas.Things to try.Things to write about.Questions I want to think about later. It’s not a perfect system, but it makes the notes feel less like a messy pile and more like something I might actually come back to. Curious how other people deal with this. Do you have a system for organizing random information, or do you mostly just save things and hope you can find them later?
The problem, in the searcher’s words
I save a lot of small stuff — a line from a book, a good comment on reddit, a podcast tip, a random idea I had in the shower — but later I can never find it or actually use it. It's scattered across screenshots, bookmarks, notes apps, and my own memory.
The problem isn't capturing, it's that none of it is tied to a reason. I save things because they feel interesting in the moment, not because I know what I'll do with them, so it all turns into a pile I never revisit. By the time I go back, I can't even remember why I saved it.
I've started trying to save things by what I'll use them for (work idea, thing to try, thing to write about) instead of by where I found them, but it's a manual habit, not a system, and it falls apart when I'm in a hurry.
What the thread shows
At least three distinct users independently describe the same failure mode — capturing information without a reason attached, then being unable to use it later — and converge on similar fixes (intent tags at capture, single inbox, organize only on reuse).
“Instead of saving things by where I found them, I try to save them by what I might use them for.”
“I like the idea of adding a note at the time of saving to explain why I wanted to store it away for later. Half the time I reflect on materials I've saved and can't remember what I wanted to do with it.”
“Nothing gets organized when I capture it. Everything goes into the same inbox, and I only organize it if I actually come back to it later.”
“A saved note without a task attached can easily become digital clutter.”
Target customer
Who
Knowledge workers, writers, and lifelong learners who habitually save quotes, tips, links, and ideas from books, podcasts, and social media
Context
They hit this problem days or weeks after saving something, when they try to find or reuse a note and either can't locate it or can't remember why they kept it.
What to build
- Quick-capture input for text, links, and screenshots
- Mandatory or one-tap 'intent' field at time of save (e.g. work idea, thing to try, thing to write about, question to think about)
- Single default inbox with no forced upfront categorization
- Search and filter by intent tag and keyword
- Simple resurfacing view showing uncategorized items to revisit only when needed
Build note — Could layer on top of existing note apps via API/export rather than building a full standalone editor; OCR would be needed for screenshot capture; core differentiator is the intent-tagging step, not storage itself.
Later, if it lands
Who’s already out there
General-purpose workspace for notes, databases, and docs, often used as a personal knowledge base
Gap: Requires users to manually build and maintain their own organization system; nothing prompts 'why did I save this' at capture time, so notes still pile up unsorted.
Local markdown note-taking app built around linking notes together
Gap: Optimized for linking and structure after the fact, not for capturing intent at the moment of saving; still leans on the user to organize.
Syncs and resurfaces highlights from books, articles, and podcasts
Gap: Good at collecting and resurfacing highlights but doesn't ask what the highlight is for, so it solves capture, not the 'now what' problem the thread describes.
Demand read
Two commenters beyond the OP independently describe the same recurring pain and adopt informal workarounds, suggesting the problem is real and recurring, but nothing in the thread indicates anyone would pay for a tool to solve it.
Worth digging into before you build
4 to considerNo idea is a sure thing at this stage — these are open questions worth checking yourself, not a verdict against building it.
Generic Idea
Note-taking / personal knowledge management is a saturated category (Notion, Obsidian, Evernote, Readwise already dominate it); differentiation is unproven.
Weak Demand
No pricing statements, paid-tool mentions, or explicit willingness-to-pay language anywhere in the thread.
Thin Source
Several comments were removed by moderators or deleted, leaving a small, partially intact comment section (18 comments, many stripped) to support the page.
Other
A user (trenno) explicitly accused the OP's replies of sounding AI-generated, and mods removed multiple thread comments for being AI-generated/spam; reviewer should verify the authenticity of OP's quoted statements before publishing.
