The reality check before the build.
Paste your idea. SignalCheck asks the questions you haven’t answered, finds the competitors you haven’t clocked, and tells you what to validate in the next seven days.
What lands in your inbox, 2–3 minutes after you paste.
You're not building a meal planner. You're building behavior change for people who already know what to eat — and that's a different product, a different price, and a different channel.
“Honestly every app just tells me to eat less carbs. I need something that knows my body responds weird to oats but fine to pasta.”
Who pays — the diabetic or their insurer?
B2C this is a £9/mo app competing with free logger apps. B2B, it's a £20M health-plan integration play. These are different companies.
- 1DM 10 people in r/diabetes_t2 who posted about frustration with existing apps. Ask what they'd pay for. Don't show a mockup.
- 2Email 3 diabetes educators. Ask if they'd recommend a tool like this — or if their patients already have something.
- 3Read the last 30 days of Nutrisense App Store reviews. Find the 3 most repeated complaints.
From paste to brief in three moves.
No forms. No frameworks. You see the research happening live.
One paragraph. Rough is fine. The messier it is, the more there is to challenge.
Questions generated live from what you wrote — the ones a senior PM would ask across the table.
Watch research run in real time. Then a sharp brief lands — competitors, evidence, the moves for this week.
Why not just ask ChatGPT?
Fair question. General AI tools are built to agree with you. SignalCheck is built for one job.
- Trained to agree — praises your idea
- Doesn’t dig Reddit, app stores, or live competitor pages
- Hands you ten options, no direction on what to actually do
- Generic frameworks — Porter’s, SWOT, blah
- Pushes back where a senior PM would
- Live research across Reddit, reviews, and competitor sites
- One brief with the 7-day moves that matter
- Tuned for pressure-testing product ideas. Nothing else.

FAQ
How long does a run take?+
Two to three minutes. You see the research happening as it runs — that’s the point.
Is my idea private?+
Yes. Your ideas aren’t shared, sold, or used to train anything. Your brief is yours.
What if I don’t agree with the brief?+
Good. The brief is the start of the conversation, not the end. The point is to give you something sharper to think against.
Who is this for?+
Founders, indie hackers, and PMs with a paste-box full of ideas and no way to pressure-test them. If you’ve ever built something for three months and found out it already existed — this is for you.
