Start Monitoring FreeMost mentions never tag you. You're missing all of them.
The Hacker News thread about your product. The Bluesky reply comparing you to a competitor. The Lobsters post where someone is asking for exactly what you built. None of them tagged you. None of them showed up in your notifications. They happened, got traction, and moved on without you.
The platforms your audience actually uses. The ones your current tools don't cover.
Generic social listening tools were built for Twitter and Instagram. Messijo covers Bluesky, Hacker News, and Lobste.rs, the places where developers discover tools, share frustrations, and ask for recommendations. Reddit support is coming soon.
Keyword matching finds the signal. Lenses cuts everything else out.
Most monitoring tools send you every mention that contains your keyword, including noise, spam, and posts that have nothing to do with you. Lenses is different. Describe what you actually care about in plain English: "people frustrated with [competitor]" or "posts asking for a tool like mine." Lenses uses AI to classify every mention before it reaches you, so your alerts are relevant, not relentless.
Alert the right person, the right way.
Some mentions need a Slack ping the moment they go live. Others belong in a weekly digest. Some should trigger a webhook that logs to your CRM or fires an automation. Messijo delivers to email, Slack, Discord, SMS, and webhooks so every mention reaches the right person in the format that works for them.

Google Alerts only covers indexed web pages and misses Bluesky, Hacker News, and Lobste.rs entirely. It also does not catch real-time posts or untagged mentions on social platforms.
Messijo monitors those communities directly and delivers alerts the moment a match appears, with Lenses to filter out the noise before it reaches you.
Messijo delivers alerts via email, Slack, Discord, SMS, and webhooks. You can mix and match. Route urgent mentions to Slack and lower-priority ones to a weekly email digest. Webhooks let you push mention data into your own tools or automation pipelines.
We currently support listening for keywords on BlueSky, HackerNews, and Lobste.rs. We plan on adding other platforms as we grow. Feel free to let us know which additional platforms you would like us to support.
Mention and Brand24 focus on mainstream social platforms like Twitter and Instagram. They do not cover Bluesky, Hacker News, or Lobste.rs, which is where developers discover tools and talk about products like yours.
If your audience is on those platforms, those tools are missing most of your mentions.
Lenses are AI-powered filters you set up in plain English. Instead of getting every mention that contains your keyword, you describe the intent you care about: “people frustrated with [competitor]” or “posts asking for a tool recommendation.”
Lenses classifies each mention before sending an alert, so you only hear about the ones that matter.
