Capabilities

Intelligence, not just data.

AI Signal Classification

Every post auto-classified into Pain, Request, Praise, Question, or General. Plus intent detection: buying signals, competitor switching, and alternative-seeking behavior.

Competitor Intelligence

Track up to 10 competitors across Reddit. Monitor mention volume, sentiment shifts, top complaints, and praise. Get AI-generated insight reports on strengths and weaknesses.

Revenue Signals

Surface high-value posts: buying intent, churn interception, and users actively seeking alternatives. ICP matching scores every post against your ideal customer profile.

Trend Tracking

Track keywords across subreddits over 30, 60, and 90 days. Sparkline visualizations, volume change percentages, and automatic spike/drop alerts when topics surge.

Audience Groups & Monitoring

Organize subreddits into audience groups. Set keyword monitors with intent-based filtering. Get Chrome notifications when new matches appear—hourly, daily, or weekly.

Founder Brief & Digests

AI-scored opportunity items ranked by tier. Scheduled email digests with top insights, competitor shifts, and trending threads. Export to CSV, PDF, or Markdown.

Built different

Privacy-first. No API keys. No compromises.

On-Device AI

Gemini Nano runs classification directly on your machine. Your data never leaves your browser. Cloud AI (Gemini Flash) available as an opt-in upgrade for deeper analysis.

Zero API Keys

Works directly on Reddit pages you visit. No Reddit API approval, no developer accounts, no rate limits to manage. Install and go.

Bring Your Own Keys

Plug in your own OpenAI, Anthropic, or Mistral API keys for classification. Use your existing quota. Works on every plan, including free.

4-Tier AI Cascade

Gemini Nano (on-device) → Gemini Flash (cloud) → Your own keys (BYOK) → Heuristic fallback. Classification always works, even offline.

02

Browse & Extract

Visit any subreddit and pull posts directly from the page. Or search across subreddits from the side panel. AI classifies everything automatically.

03
