Frequently Asked Questions
What is Sonar?
Sonar scans Reddit and Hacker News every 4 hours for posts where people are asking for tools, apps, and solutions that don't exist yet. Each signal is scored by engagement, recency, and willingness-to-pay indicators.
Where does the data come from?
We monitor 18 subreddits (like r/startups, r/SaaS, r/selfhosted, r/programming) plus Reddit's search API and Hacker News via the Algolia API. All data comes from publicly available posts.
How is the demand score calculated?
The score (0-100) combines upvotes, comment count, post recency, and willingness-to-pay signals (phrases like "I'd pay for" or "shut up and take my money"). Higher scores indicate stronger validated demand.
What's the difference between Free and Pro?
Free gives you 10 signals per day with basic filters and up to 25 saved signals. Pro ($19/mo) unlocks unlimited signals, unlimited saves, CSV export, and priority support.
How do I cancel my subscription?
You can cancel anytime from your Stripe billing portal. Your Pro access continues until the end of your billing period. No cancellation fees.
What are conversation types?
Each signal is classified as a Solution Request (someone looking for a tool), Pain Point (someone frustrated with the status quo), or Money Talk (someone discussing pricing or willingness to pay).
How often is data updated?
Every 4 hours. We scan all monitored subreddits and search queries, score new posts, and clean up signals older than 90 days.
Can I export the data?
Pro users can export filtered signals as a CSV file. Click the 'Export CSV' link in the filter bar on the feed page.
