Comment Forge

Generate Reddit-native comments that sound like a real person wrote them. Powered by a real Reddit comment corpus and a 7-dimension QA pipeline that catches AI fingerprints.

What It Does

Feed it a post title, body, and existing comments. Get back a natural reply that:

• Matches the thread tone using corpus-informed few-shot prompting
• Passes AI detection via 7-dimension QA scoring (naturalness, value, subtlety, tone, detection risk, length, AI fingerprint)
• Strips AI tells with deterministic anti-AI cleaning (em-dashes, smart quotes, 50+ AI vocabulary swaps)
• Adds subtle humanness with smart typo injection (40% chance, max 1 per draft, never on product names)

Two Modes

Value-First: Pure tactical advice. No product mention. Great for building karma and credibility.

Product-Drop: Mention a product naturally in the reply. Auto-fit scoring determines if the product fits the thread (1-10 score). If it doesn't fit naturally, falls back to value-first.

Pipeline

1. Corpus Sampling - Stratified, score-weighted real Reddit comment examples
2. Fit Scoring - Classify thread intent, recommend mode (optional, for product-drop)
3. Draft Generation - Corpus-informed few-shot prompting via Gemini or OpenRouter
4. QA Pipeline - Score, revise, re-score loop (3 attempts for product-drop, 7 for value-first)
5. Anti-AI Cleaning - Deterministic post-processing strips AI vocabulary, em-dashes, smart quotes
6. Human Touch - Smart typo injection for believable imperfections
