Understanding Your Score (0-100)

Post Volume (0-50): How many users requested something similar

Idea Similarity (0-50): How closely existing solutions match your concept

A high post volume with low idea similarity suggests an underserved market opportunity.

Startup validation software that shows its evidence

Most AI idea validators can critique a pitch. Trend Seeker checks whether similar problems and requests already appear in real market data, then lets you inspect the matches yourself.

Evidence before opinion

Read the community posts, podcast discussions, app reviews, and other demand signals behind the score instead of relying on an unsupported AI verdict.

One idea validation platform

Compare matched demand, related business ideas, search momentum, and competition without stitching together separate research tabs.

Built for specific startup ideas

Describe the customer, problem, and product clearly. Semantic matching finds related language even when users do not phrase the problem exactly as you do.

Idea validator questions

Trend Seeker turns your idea description into a semantic search query, matches it against 147,919 market signals, and scores the strength and similarity of the evidence. The result shows the requests, nearby validated ideas, related search trends, and available competition data behind the score.

Yes. You can run free validations without creating an account, subject to a daily limit. Free results include a validation score, matching market signals, similar ideas, and available market context. Pro adds unlimited checks and AI-generated analysis.

The platform matches ideas against evidence from Reddit, podcasts, job ads, Google Trends, Apple App Store and Google Play reviews, other public product reviews, launch sources, and online communities.

Yes. The validator works best when you describe a specific problem, target customer, and proposed solution. It is useful for SaaS, micro SaaS, mobile apps, AI products, and service businesses where people discuss the problem online.

Trend Seeker is a demand-evidence alternative: it searches real market signals instead of assessing only the text of your idea. AI-only tools can still be useful for brainstorming, so many founders combine both approaches before interviewing customers or running a landing-page test.

When related data is available, the result shows tracked Google Trends queries, opportunity scores, market characteristics, and competitors from the closest validated ideas. These are comparable-market indicators, not claims that your exact idea has already been proven.
