Choose Syften if
Fast keyword monitoring across many communities, with filters and Slack delivery.
Watch out: Filtering is still keyword and rule based, so you write and maintain the filters that separate buyers from noise.
Choose Octolens if
AI relevance filtering across a dozen developer and social platforms, with an API, webhooks and an MCP server.
Watch out: Annual billing from $159/mo is a lot if Reddit is where your buyers are. You pay for coverage you may not use.
The short version
Good for teams that want reach across many platforms and are happy tuning filters by hand. Great for dev-tool companies tracking every platform. For Reddit leads alone, overkill.
Or skip both
If what you want is the posts where someone is asking to buy, Leadhoot scores every new post on Reddit, X and Threads 0–100 for buyer intent and sends only the high scorers to email, or Slack on Agency, within a minute.
