Trendalyse is an AI market research tool grounded in real Google Trends search interest, using SerpApi, with insights by DeepSeek Flash. The product appeared on Show HN on 7 November 2026. You can read the launch thread at https://news.ycombinator.com/item?id=50406012.
What it is
Market research often starts with a guess about what people want. Trendalyse starts with what people actually search for. It pulls real Google Trends search interest through SerpApi, then uses DeepSeek Flash to turn that data into insights a team can act on.
Users can compare up to five topics side by side, explore related queries, and export CSV data for further analysis. The tool also helps shape a focused, testable hypothesis, so a research question becomes something the team can check against the real world.
Trendalyse includes a research guide to help users get useful results from the tool. It also keeps its framing honest: search interest is not purchase intent. A topic can trend without anyone wanting to buy, so the official site advises taking the hypothesis to real customers before acting on it.
Using Trendalyse requires your own SerpApi account, since the Google Trends data comes through that service.
