Today we shipped the biggest update to Niche Sonar since launch — a set of features built around one idea: make it effortless to go from "interesting problem" to "I could build this."

What's new

Like & Save on every opportunity. Tap ♥ to signal what resonates, or ★ to save a card for later. Your saves live on the new Favorites page.
Favorites that stick. Our rankings refresh every week, but a saved card keeps its full snapshot — so an opportunity you saved a month ago is still there exactly as you found it, even after the data moves on.
One-click AI solutions. On any saved card, hit Get Solution and you'll get a short, concrete product idea plus an honest difficulty rating (Easy / Medium / Hard) for shipping an MVP. It's meant to be skimmable in 30 seconds — a starting point for "what would I actually build here?"
A dev blog. You're reading it. Build notes and changelogs as we go.

A couple of engineering notes

Solutions are generated once, then shared. The first time anyone asks for a solution to a given problem, we generate it and cache it — keyed by a normalized version of the problem itself. Everyone who asks afterward gets that same answer instantly, with no second AI call. It keeps responses snappy and our costs sane, and it means popular problems effectively get a "community" answer.

Trial users get a real taste. During your 7-day trial you get 3 fresh AI solutions to try the feature properly; cached ones are always free to view. Paid plans are unlimited.

Knowing who's around, without sessions. We wanted lightweight "active users" stats, but our auth is stateless (JWT) — there's no session table to count. So we track a throttled "last seen" timestamp on activity instead, which powers both the daily summary and an at-a-glance "online now" number.

What's next

More signal on each opportunity, and deeper solution breakdowns for those who want to go past the 30-second version. As always — if there's something you want to see, tell us.
