Primary use cases

Lead discovery from public threads

Search many communities in one run, rank posts for buying intent and fit, then open the threads worth replying to first - without tab-hopping.

  • One workflow across the sources your plan includes (e.g. Reddit, X, Hacker News, GitHub, and more)
  • Intent and sentiment on each result so urgency floats to the top
  • Manual search for deep dives; saved history on paid plans
Explore use case

Idea validation & demand signals

Use Trending Problems and cross-community search to see what people complain about before you commit engineering time.

  • Trending Problems for category-level demand signals
  • Cross-platform themes with sentiment and intent
  • Fast feedback from real conversations, not surveys alone
Explore use case

Brand & competitor conversations

Find where people talk about your product, solution, or competitors - then read the same intent signals on every result.

  • Brand, alternatives, and competitor names in one ranked workflow
  • Triage praise, risk, and opportunity with intent on mentions
  • No separate “social listening” silo
Explore use case

Auto Search & digests

On paid plans, **Auto Search** runs **scheduled passes** using the **phrases, sites, and cadence** you save for **your brand** in **Settings**; optional **digest alerts** notify you in connected channels when there are **new** high-signal posts since the last digest.

  • Your brand bundles keywords/phrases, platforms, and how often Auto Search runs
  • Automatic Auto Search runs do not consume manual search quota
  • Optional digest channels where your plan supports them
Explore use case

Content from real buyer language

Mine threads for phrases, objections, and themes your audience already uses - then feed SEO, landing pages, and campaigns.

  • Cross-platform themes instead of a single-site echo chamber
  • Exports where your plan allows for stakeholder updates
Explore use case

MVP validation from pain threads

Listen for feature gaps, workarounds, and “I wish” moments where power users vent - then prioritize what ships next.

  • Pain and feature-adjacent language from search
  • Intent signals separate idle chatter from motivated users
  • Competitive context when buyers compare tools in-thread
Explore use case

Competitor & switching intent

Mine “alternatives to X” and switching threads for positioning, comparisons, and ethical outbound.
