Subscription Auditor for Forgetful Brains is a startup idea for people with ADHD and consumers. People with ADHD pay for forgotten subscriptions for years because opening the bank app and decoding the charge list is itself an executive-function task. A thread in r/ADHD drew 31 upvotes and 39 comments between Sep 14, 2026 – Oct 14, 2026. People get by with Rocket Money and Bank app subscription lists, and that still leaves this job open. Hotness is 2.85, Simmering. Real but moderate pain. Some willingness to pay. The thread drew 31 upvotes and 39 comments. Crowded with decent tools. A few weeks of work. A first version is a moderate amount of work, about 3–4 weeks, priced under $10 a month and charged as a free tier and a paid upgrade. 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.

A way through
Connect read-only to the bank, auto-detect recurring charges, explain each service in plain language and start cancellation with one click.
MVP scope
- Give people with ADHD and consumers a way to do this in one sitting: A read-only bank connection that finds every recurring charge, explains it in plain English and cancels in one tap.
- Persist the result and show it again after a reload.
- State the empty case when there is nothing to show yet, with one next step.
- Charge later with a free tier and a paid upgrade, under $10 a month. The free path must finish the core job once.
- Ship the mobile app only. Leave Rocket Money to keep the jobs they already do well.

Questions
Is this idea already taken?
People already use Rocket Money, Bank app subscription lists. 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?
Moderate. A tight MVP is about 3 weeks (3–4 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 people with ADHD and consumers. Charge a free tier and a paid upgrade, 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.
