The real question
Do you need to find an idea, or prove one works?
Most comparisons treat these tools as competitors, but that framing is wrong. They solve different problems at different points in the process.

Fair assessment
What IdeaBrowser does well
IdeaBrowser has built a real idea-discovery platform with a lot of thought behind it.
The catalog
2,000+ pre-researched ideas with market sizing, competitor context, execution outlines, and trend signals. Each entry represents real research condensed into an actionable format.
Greg Isenberg's ecosystem
Built by the host of The Startup Ideas Podcast (ex-Reddit, ex-TikTok advisor). Pro bundles a new 7-day accelerator every month, live with the team, plus events and 600+ tool deals. The brand is real.
Daily idea cadence
The Idea of the Day creates a habit loop: one fresh idea with a full walkthrough, every day. For founders in browsing mode, that cadence works better than a static list.
The pricing reveal
Can IdeaBrowser validate your own idea?
Since October 2026, IdeaBrowser’s pricing page sells one plan, Pro at $1,499/yr, and it is the only way in.
TierPriceValidate your own idea?
Free
$0
No. Daily Idea of the Day only (24hr access).
ProMinimum for your idea
$1,499/yr
Yes. 20 deep-research reports a year on your own ideas, plus 'Should I Build This' and 'Roast This Idea' playbooks over MCP. No source links in the output.
Starter ($499/yr) and Empire ($2,999/yr) left the pricing page in October 2026. Existing Starter members can still upgrade to Pro from the page. Both plans are still listed in the page’s JSON-LD. Checked 12 October 2026.
With Preuve AI: $59 one-time for a full source-linked report on any idea.
No annual commitment. No tier gates. That is about 25x less than IdeaBrowser Pro for a comparable validation report.
What Preuve AI does differently
Live source scanning
60+ sources searched in real-time. Crunchbase, Google Trends, Reddit, Product Hunt, and G2 are in the mix, pulled live rather than from training data.
Verifiable claims
Click any data point to see where it came from. Every competitor, funding round, and demand signal links back to its origin so you can check the claim yourself.
Honest scoring
Only 17.5% of ideas earn a go verdict. Six scoring frameworks run against live data, so the score reflects what the market actually shows rather than what a founder wants to hear.
Investor-ready deliverables
$499 package with pitch deck, investment memo, 18-month financial model, and competitive teardown. Built for due diligence, not brainstorming.
Interactive dashboard
Shareable link with 21 interactive sections. Filter competitors, drill into market data, and share specific sections with co-founders or investors.
Competitor intelligence
Actual competitors with their funding history, current pricing, and traction numbers pulled live. Not a list of names generated from an LLM's training data.
The verdict
Who should use which tool
This is not an either/or. IdeaBrowser helps you find the idea worth building, and Preuve runs the evidence check once you have one.
Best for most founders
Choose Preuve AI if
- You have a specific idea and need evidence it will work
- You want source-linked proof you can verify yourself
- You need investor-ready deliverables for fundraising
- You want honest scoring that tells you when to pivot, not just what sounds good
→ Most founders start here
Choose IdeaBrowser if
- You don't have a specific idea yet and want to browse opportunities
- You want daily inspiration with trend context and market signals
- You want a monthly 7-day accelerator and a builder community
- You follow Greg Isenberg and want access to his ecosystem
→ Best for finding an idea to build
Use both? Browse IdeaBrowser to find an idea worth exploring, then run it through Preuve AI to see if the data actually backs it up before you spend a weekend building.

FAQ
Common questions about Preuve AI vs IdeaBrowser
Is IdeaBrowser worth $1,499 a year?
IdeaBrowser Pro ($1,499/yr) is now the only plan on its pricing page. It bundles 2,000+ pre-researched ideas, 20 deep-research reports a year on your own ideas, 22 playbooks that run inside Claude, ChatGPT, Cursor and Codex over MCP, and a new 7-day accelerator every month. If you are in discovery mode and will use the catalog, the playbooks and the accelerator, that bundle is what you pay for. If you already have an idea and need to validate it, Preuve AI delivers source-linked validation for $59 one-time.
Can IdeaBrowser validate my own startup idea?
Yes, with the Pro membership ($1,499/year), now the only plan on its pricing page. Pro includes 20 deep-research reports a year on your own ideas, the same deep research that powers its Idea of the Day. However, the output does not link claims to their sources. Preuve AI validates your idea for $59 one-time and links every data point to one of 60+ live sources so you can verify the evidence yourself.
How does IdeaBrowser research your own idea?
Pro ($1,499/yr) includes 20 deep-research reports a year on your own ideas, the same deep research that powers the Idea of the Day. An MCP connector brings that research into Claude, ChatGPT, Cursor and Codex, where 22 playbooks such as 'Should I Build This', 'Roast This Idea' and 'Competitive Analysis' pressure-test the idea. Reports sit in your Hub project workspace. The main limitation: claims are not linked to their data sources.
How does IdeaBrowser compare to Preuve AI?
They solve different problems. IdeaBrowser is an idea discovery catalog: browse 2,000+ pre-researched ideas, get daily trend reports, and use AI to generate new concepts. Preuve AI is an idea validation engine: paste your specific idea and get a source-linked report with viability score, up to 15 competitors with real funding data, market sizing, and 3 pivot directions. IdeaBrowser helps you find an idea ($1,499/yr). Preuve helps you prove one works ($59 one-time).
Does IdeaBrowser have a free tier?
IdeaBrowser offers a free Idea of the Day: one curated startup idea with a walkthrough, available for 24 hours. Accessing the full database, trend reports, or AI tools requires the $1,499/yr Pro membership. Preuve AI offers a free scan that returns a viability score, top risks, and 2 competitor previews.
