LiquidUser vs Octolens
Octolens is social listening for B2B software teams: brand, competitor and buying-intent mentions across many platforms, filtered by AI and routed to Slack, email, webhooks or MCP. Vercel, PostHog and Supabase are named customers.
Octolens tracks the keywords you give it across many platforms. LiquidUser starts from your website and looks for people describing the problem you solve.
Where each one is better
What Octolens does better
Octolens labels every mention with an AI relevance level (high, medium or low), tags such as buy intent, bug report or competitor, and sentiment. It covers far more places than LiquidUser, including Reddit, LinkedIn, GitHub, Stack Overflow, YouTube and, on Scale, podcasts and newsletters. Seats are unlimited, and the API, webhooks and MCP come with every plan.
Pick Octolens if a team needs brand and competitor monitoring across many platforms and has a team budget.
What LiquidUser does that Octolens doesn't
- It starts from your website instead of a keyword list, and shows what it understood with the page behind each claim.
- It maps each conversation to the claim on your own site it matches, with the page it came from, so you can check the fit in seconds.
- Every person comes with a reply draft or brief that you post yourself, from your own account. Nothing is ever sent for you.
- Memory carries your corrections, competitors and known customers across days, so tomorrow's list starts from what you taught it today.
