Universal Recall Search for Everything You Saved is a startup idea for knowledge workers and students. People constantly save useful information into folders, tags and bookmarks, but it never helps them find it again when they actually need it. A thread in r/productivity drew 55 upvotes and 49 comments between Sep 14, 2026 – Oct 14, 2026. People get by with Rewind/Limitless, Mymind, and Raindrop, and that still leaves this job open. Hotness is 2.75, Simmering. Real but moderate pain. Some willingness to pay. The thread drew 55 upvotes and 49 comments. Crowded with decent tools. Needs integrations or data deals. A first version is a hard build, about 5+ weeks, priced under $10 a month and charged as a subscription. The pain, the source, the alternatives, the scope notes, and the questions on this page are free to read and free to build from. The agent starter prompt is the paid part. The first slice is on the page. One credit unlocks the rest, to paste into a coding agent, download as Markdown, or send as a private link.

Market size · estimate
How big this could get
A bottom-up estimate for Universal Recall Search for Everything You Saved: real customer counts × a realistic price. Not a forecast.
$1.5B a year
16M workers · 10% of employed people in the US
$307M a year
3.2M workers · Mac and Windows users who find it online
$1.5M a year
16,000 workers · 0.5% of the reachable segment in three years
What that means
16,000 workers at $8/mo = $1.5M ARR
Low confidenceHow we estimated this
- Base: 163,000,000 employed people in the US.
- Has the problem: 10% (assume 40% are knowledge workers and a quarter of those save enough to need it).
- Revenue per worker: $96 per year ($8/mo).
- Reachable: 20% (Mac and Windows users who find it online).
- Three-year capture: 0.5% of the reachable segment.
TAM = customers with the problem × revenue per customer. SAM = the part an early product can reach. SOM = a conservative three-year share of SAM. Bars use a log scale. Shares marked “assume” are our judgment, not measured.

Or we build it
Your first version, shipped by our team.
A working product in your repo, built from this PRD. You own the code.
$1,000 scoping fee, credited toward the build.
Equity instead of cash is an application, not a checkout →Questions
Is this idea already taken?
People already use Rewind/Limitless, Mymind, Raindrop. Those options do not do the job in the solution above. The idea is free to build. Nothing here is an exclusive claim.
How hard is a first version?
Hard. A tight MVP is about 5 weeks (5+ weeks), assuming the regulated or partner-gated parts are stubbed. The paid prompt turns that into tasks.
Who would pay, and how?
The audience is knowledge workers and students. Charge a subscription, and test a price under $10 a month. Willingness to pay is one input to Hotness, not a promise that someone will buy.
Can I use the evidence?
Yes. Build the product. The thread title is a short excerpt with a link, not a quote we are putting in someone's mouth. Exact post dates and verbatim lines are added only after a manual check. Ideas are suggestions, not medical, legal, or financial advice.
