Questions, answered.

The useful details about what Signl watches, how it qualifies people and where they go next.

What is Signl?

Signl is a social listening engine for LinkedIn. It follows the conversations your market takes part in (your own posts, your competitors’, and the creators your buyers follow), picks out the people showing buying intent, checks each one against who you sell to, finds a verified work email and writes a reason to reach out and an opening line grounded in what they said. It keeps listening in the background, and works from the Signl inbox or from Claude, ChatGPT, Grok or any agent that speaks MCP.

What can I watch?

Add a LinkedIn profile, post or search, or an X account or search. Signl collects public comments and replies, plus reactions and reposts, then keeps watching each source for new people in the background.

How does Signl decide who is worth contacting?

Signl compares each person with your ICP: what you sell, the roles and companies you target, where you sell and the offers you can lead with. The people who fit arrive with a confidence score, the reason they matter, likely intent and a grounded opening line.

Does Signl send messages for me?

Today, Signl prepares, qualifies and routes people, and your connected outreach tool sends the message. Review people in the Inbox and send them yourself, or use Autopilot rules to route the right people to your existing sales workflow. Coming soon: send LinkedIn connection requests and messages from your own account, directly from Signl, inside the hours you choose.

Can my AI agent use Signl?

Yes, it was built for that. Signl is a remote MCP server, so Claude, ChatGPT, Grok, Cursor and any agent that speaks MCP can add sources, ask who engaged this week and why they fit, write and edit first messages, and send people to your tools, without leaving the conversation. Connecting takes a minute: paste one URL and sign in. You can also use the Signl app on its own.
