About
Social Line is an AI social listening platform that tracks what real people say about your brand, product, or competitors across X, Instagram, Facebook, LinkedIn, Reddit, TikTok, and Threads.
Type one keyword and get a ranked queue. Searches run on your schedule, from every 5 minutes to daily, in any language. Every mention arrives scored for sentiment, eight emotions, intensity, and estimated reach, so the post that needs a reply today rises to the top instead of getting lost in a timeline.
Key features
- 7 platforms in one feed: X, Instagram, Facebook, LinkedIn, Reddit, TikTok, Threads
- AI scoring on every mention: sentiment, emotion, intensity, and reach
- Works in any language, scored in the language it was written in
- Triage queue: mark mentions Open, Done, Follow up, or Irrelevant
- Auto-categorization, 14-day trends, and a 0 to 100 reputation score
- Boolean keyword modifiers for precise matching
- In-dashboard AI assistant
- MCP server: every dashboard action is exposed as a tool, so the AI agent you already use can create keywords, run searches, and read scored mentions directly
Use cases
- Brand monitoring and reputation management for small brands, cafes, D2C shops, and startups
- Competitor tracking and campaign monitoring for marketing teams and agencies
- Lead discovery, such as catching people who post that they are looking for a flat, a service, or a product
- Crisis and disaster response for public agencies. During the September 2026 floods in Bihar, India, Social Line surfaced a rail bridge closure from Hindi and English posts before the railway confirmed it.

I was trying to guess why they churned… I was saying: one yes/no question — did you churn because of pricing? And people started to answer: yes, yes I did, because of that.
Email every churned user with a single yes/no guess — reply rate hits 100%
Cancellation popups produce generic, useless answers. Email each churned customer personally with one specific yes/no hypothesis based on their profile and use case. The reply rate is near 100%, and the resulting mental model is what cuts churn.
Lower priced apps have way better retention than higher price apps... it's like when it's like oh it's only 20 bucks and yeah I'm still kind of using it here and there it's like it's a way different decision if it's 20 bucks versus 40 versus 60 versus 100.
Lower-priced apps retain far better — price high only if you can prove the value
SOSA 2025 retention-by-price data is stark: the cheaper the subscription, the lower the renewal friction. A $20/yr app survives casual usage; a $100/yr app does not. The lesson isn't to undercharge — it's that your price has to sit on the right spot on the demand curve, and most apps haven't tested it. If you're charging premium, you need to be delivering Ladder-level retention to justify it.
There's a play for whatever you're stuck on.
