Test your idea before you spend months building it.
You have an idea, and AI tools can turn it into working software faster than ever. The risk is spending months building something nobody wants. ProductLobster runs the work a senior product manager would do first: it researches who would actually buy it, sizes up the competition, shapes the solution, and hands you a clickable prototype plus a build-ready plan — pausing at three points for you to make the big calls.
Free during beta. No credit card required. No product management experience required.
Seven stages. Three checkpoints. About an hour, and you can step away anytime.
It runs in the background, so you can step away and come back when a checkpoint needs your call. Each stage adds to your product's memory, and every later stage builds on it.
- 01
Customer research
Who are your customers, really, and what would make them switch to you? ProductLobster works from real evidence, not generic personas.
- 02
Competitive analysis
Who else is solving this, and how? You get a clear map of the competition — what they do well, who they serve, and where the gaps are.
- 03
Customer demand analysis
Would people actually switch, and where is the demand strongest? ProductLobster weighs what pulls customers toward your idea and what holds them back, then helps you pick the segment to aim at first.
Checkpoint 1 — Target Segment - 04
Strategic framing
What is the one thing worth building, and what are you saying no to? ProductLobster forces the hard choices into a clear strategy you can act on, and you lock the job worth solving.
Checkpoint 2 — Job Worth Solving - 05
Solution design
A focused solution scoped to what matters: what's in, what's out, and where the risky unknowns are. Every part traces back to the evidence.
- 06
Clickable prototype
A working, clickable prototype — up to six screens, on desktop or mobile — built from your strategy, not a generic template. Refine any screen by chatting with it.
Checkpoint 3 — Solution Shape + Prototype - 07
PRD generation
A build-ready plan grounded in everything above, where every requirement traces to a decision you made. Hand it to an AI builder or an engineering team with confidence.
What you walk away with.
- A customer segment worth aiming at, backed by real evidence
- A competitive map showing where the gaps are and where the bar is set
- A clear read on whether customers would actually switch, and what it would take
- A strategy with explicit yeses and explicit nos
- A focused solution design: what's in scope, what's out, and where the risks are
- A clickable prototype you can share with customers and stakeholders
- A build-ready plan an AI builder or engineering team can act on
- Your Product Brain, seeded with the whole decision trail and ready to compound
