Built for Reddit-safe marketing

How SubDude works

Four tools that work together: analyze the subreddit, score your draft, rewrite it to sound native, then follow a custom playbook.

Subreddit Analyzer

Know the rules before you break them.

SubDude fetches live subreddit data — rules, sidebar, enforcement history — and runs it through a deterministic scoring engine to give you a precise promotion risk score across 5 dimensions.

  • Promotion tolerance score
  • Link tolerance score
  • Account trust expectation
  • Enforcement strictness
  • Topic relevance fit
Draft Scorer

Catch issues before Reddit does.

Paste your post draft and SubDude runs it through a 4-layer risk analysis: spam detection, contribution quality, trust signals, and context depth — before blending with AI classification.

  • Spam score
  • Contribution signal score
  • Trust & founder language detection
  • Context depth score
  • Specific line-by-line warnings
AI Rewriter

Sound like a Redditor, not a marketer.

When your draft scores too high, our GPT-4.1 rewriter transforms it into Reddit-native language — removing CTAs, adding questions, softening founder language — while keeping your core message intact.

  • Removes promotional tone
  • Adds contribution signals
  • Softens founder language
  • Preserves your message
  • Shows before/after diff
Promotion Playbook

A strategy, not just a score.

Get a full custom playbook for any subreddit — posting frequency, best times, content types, karma-building tactics, and real example posts you can copy and adapt.

  • Posting frequency guide
  • Best times to post
  • Phrases that work vs. get banned
  • Sample post templates
  • Karma-building strategy

How the scoring works

We never rely solely on AI. Our pipeline is deterministic-first, AI-enhanced.

Deterministic first

Rule engine runs before AI — never rely on a language model to read actual subreddit rules.

Blended scoring

60% deterministic + 40% AI for reliable, explainable scores that improve over time.

pgvector embeddings

Subreddit data is embedded and stored in Supabase pgvector for semantic similarity lookups.

Context-aware rewrites

Rewrites use the actual subreddit name, rules, and warnings — not a generic prompt.
