I launched EconLens three weeks ago. A few early lessons have already changed how I think about the product.
First, people want specificity. The most popular queries are not “explain inflation” but things like “compare the 10Y–2Y spread to the 10Y–3M spread and tell me which is a better recession predictor based on historical data.”
Second, the file‑upload feature is more popular than I expected. Users are feeding in bank research PDFs and asking EconLens to fact‑check projections against live data. I did not build it for that use case initially—but it makes perfect sense.
Third, mobile usage is higher than desktop. I almost did not optimize for mobile. I am very glad I did.
Finally, the free tier converts better than I thought. People run two or three serious queries, realize that live data actually changes their analysis, and then upgrade.
It is still early and I am still fixing bugs every day, but the direction feels right. econlens.app.
