One Feed.
Every Signal That Matters.

The average aspiring solo founder spends 3–5 hours a week scrolling YouTube, Reddit, and Twitter just to find viable idea signals — and still misses most of them because they're scattered across formats. Kairox replaces those 5–8 manual tabs with a single ranked feed updated in real time, structured around your skills and budget from the first scroll.

1
Radar scans around the clock
Kairox monitors YouTube, Twitter/X, Reddit, indie newsletters, and podcasts 24/7. No account linking, no saved searches, no RSS setup required.
2
Signals get a momentum score
Each emerging idea receives a live score from 0 to 100, calculated from cross-platform mention growth, engagement rate, and recency — so you can tell a genuine trend from a one-day spike.
3
Set your filters once
Choose your skills (no-code, copywriting, dev), startup cost bracket, niche, and solo-friendliness threshold. Your feed narrows from 140+ weekly ideas to the handful that match your actual life.
4
Evaluate an idea in 30 seconds
Open any card for a plain-English summary, clickable source links, effort estimate, startup cost bracket, and tagged revenue models — then save it to your personal idea board.

Score 84.
Zero Products Built Yet.

Most "trending" signals you find manually are already crowded, already peaking, or just noise. Kairox's momentum score is the first tool that tells you the difference: a score that's climbing steeply with zero dedicated products found is a genuine early-mover window — not a one-day Twitter spike. When "Niche AI resume tools for nurses" hit 84 and nobody had shipped yet, that was the window. Kairox finds it before you ever would have opened a tab.

Finally Built for
the Solo Founder.

Google Trends tells you a keyword is popular — not whether it's a business you can build. Exploding Topics tracks what's rising — but skips the effort level, revenue model, and whether you'd be the only person in the space. Twitter search floods you with noise and zero context. Kairox is the only aggregator built from day one around the solo founder's real constraint set: your skills, your budget, your two free hours on a Monday.

"I have maybe two free hours on a Monday. Before Kairox, I'd spend one of them just scrolling — YouTube rabbit holes, Reddit threads, Twitter noise. I set my filters once: No-code, copywriting, budget under $200, Health & Wellness. The full feed of 140 weekly ideas collapsed to 9 in seconds. The top result was a niche wellness habit tracker for shift nurses — momentum score 73, up 28 points in a week, zero products in the space. I bookmarked it and validated in r/nursing by Thursday."
From 140 weekly ideas down to 9 precisely matched opportunities. Moved from research to validation in the same week.

Every Tool You Were
Duct-Taping Together.

Solo founders currently juggle 5–8 browser tabs, 3–4 newsletter subscriptions, and a dozen saved searches — and still miss the trends that matter because no single source shows them all together, scored, and filtered to their constraints. Kairox replaces that entire fragmented stack with one cohesive system: from live radar to weekly digest to personal bookmarking board.

📡
Multi-source radar
Continuously scrapes YouTube, Twitter/X, Reddit, indie newsletters, and podcasts for emerging business signals — no account linking or RSS setup required.
🔥
Live momentum score
A 0–100 score per idea, recalculated from mention velocity, engagement rate, and recency — so you can tell genuine early ramp from a single viral tweet.
🃏
Structured idea cards
Every trend packaged as a 30-second scannable card: plain-English summary, clickable source links, effort level, startup cost bracket, and revenue model tags.
🎯
Smart filtering
Filter by required skills, startup cost bracket, niche, and solo-friendliness score. Set it once — your feed updates instantly to your actual constraints.
📬

Every Monday, the top 5 momentum ideas land in your inbox with a one-paragraph executive summary each — for the solo founder who only has time to read over coffee.
