Build what the marketis asking for.
Building the wrong thing costs you months; finding out costs minutes. Describe your idea and ShouldBuild reads what your market already wrote — reviews, threads, complaints — and comes back with a verdict: build it or don't, with the quotes to prove it.
No surveys. No cold DMs. No three months of building to find out.

Arturo, what are you building?
Describe it in a couple of sentences. We'll find your competitors, read what their users say, and tell you if it's worth building.
A mobile app to log strength workouts at the gym. It records your sets, weights and reps, and suggests weekly load progression. For people who train on their own and currently track everything in phone notes or Excel.
Real reviews from where your market actually talks — sources matched to your idea type
The problem
Most products start with a guess.
You think you've found a good idea. You build it. You launch it. And then you find out what the market actually wanted.
The usual way
With ShouldBuild
ShouldBuild helps you listen before you build.
The system
The market is always talking. ShouldBuild keeps you listening.
Research once and it's stale by launch day. ShouldBuild turns market signals into a continuous loop: discover, validate, decide, build, watch — and back again.

No idea yet? The market keeps a list.
Type a market. ShouldBuild reads Reddit, the app stores, Hacker News and the open web, and hands you the gaps nobody is serving — each one backed by real complaints.
Market to scan
Openings found
Offer a highly customizable and extensive exercise database with advanced filtering and easy custom exercise creation.
Implement a transparent and user-friendly pricing model, prioritizing one-time purchases or a very low subscription.
Should you build it?
Build it
Build it. The category is crowded with competent loggers, but the complaint that repeats on every platform — people drop off around week three and no app even notices — is the one nobody has solved. Enter on retention plus a genuinely generous free tier and you are competing where the leaders are not.

Signals
Based on 270 real signals — every quote links to the post it came from.
Market problem #1
Existing apps have limited exercise databases, requiring users to manually create many custom exercises.
“I miss a lot of exercises in the app. I had to create many custom ones myself, which is time-consuming and inconvenient.”
Your friends said it's a great idea. Ask people who pay.
Describe your idea and get a verdict you can argue with: the real problems, who you're up against, and whether this is worth your next three months.
Turn research into decisions, not another report.
Save what matters from any report onto one board and sort it by decision: undecided, exploring, or straight to your backlog.
Undecided
Users are frustrated with high subscription costs and prefer one-time purchases or generous free tiers.

The part a chat can't do
A complaint out on the web becomes a task in your backlog. Two clicks.
This is where ChatGPT stops. It answers, you close the tab, it's gone. Here what you learned becomes what you build — and the next analysis knows you did it.

Week after week
Then see if the market agrees with what you built.
Every week, ShouldBuild re-checks competitors, prices, ratings and new complaints — and shows you whether the problem you set out to solve is actually moving.

ProductWhat changed since last week
- +83new complaints about pricing
- +2competitors entered the market
- −0.3average rating of the leader
- +1opportunity that just opened up
- Every run is compared against the previous one, so nothing repeats itself.
- What you already built is remembered — the next report won't tell you to build it again.
- The evidence stays put: quotes, links and dates you can open months later.
You don't just research the market. You learn from it.
And then you do it again.
New complaints reveal new opportunities. Opportunities become decisions. Decisions become products. Products change the market.
ShouldBuild isn't a tool you use before launch. It's the system that keeps your product connected to the market.
For founders who'd rather validate than guess.
Whether you already have an idea or you're hunting for the next one, ShouldBuild gives you the market evidence to decide what deserves to be built.

Not another research tool
Research tells you what's happening. ShouldBuild tells you what to do next.
Go from raw market signals to a decision, a backlog and weekly feedback — without stitching five tools together.

Don't build first. Know why you're building.
