from Reddit

Your AI agent's Reddit research tool. Survived the API apocalypse that killed GummySearch. Compiles repeat analyses into pipelines that cost zero LLM tokens per run.

GummySearch died in November 2025 — 135,000 users, 10,000 paying customers, four years of work, gone overnight when Reddit revoked their commercial API access. Every replacement since is built on the same fragile foundation. RDK uses RSS: a 20-year open standard with no API keys to revoke. And once your analysis stabilizes, RDK compiles it into a deterministic pipeline that runs without any LLM tokens at all.
4 tools · 6 prompts · compiled pipes

Plus 6 MCP prompts that teach your AI agent how to score demand, map competitors, and plan outreach — executed by your own Claude / Cursor / Codex with full project context. And compiled pipes that pre-forge stable workflows into zero-cost DAGs.
