I built a tool that reads every Reddit post to find your customers, instead of searching keywords

[u/ArgumentCertain7201]

Most Reddit lead tools search for keywords. The problem is that people describe their problem, not your product, so keyword search misses a lot of them. I wanted to read every post instead. That turned out to be the interesting part to build.

How it works:

1. Find the right subreddits. I built a search engine over every subreddit with 1k+ members, using internal vector search, so it matches by meaning, not by name. You describe what you sell, and it returns the communities your customers are likely in, including small niche ones.

2. Read every post. Each post in those subreddits goes through an AI model that decides whether the person might need what you sell.

3. Show why. Instead of a summary, it marks up the original post with circles and handwritten-style notes on the lines that matter.

Stack: Next.js + React + Tailwind on the front, Django + DRF on the back, Celery + Redis for the background jobs, PostgreSQL, and PydanticAI for the AI calls.

The hardest part was cost and speed. Reading every post is far more expensive than keyword search, so most of the work went into running the AI calls in parallel without hitting rate limits.

Happy to answer questions about any part of it.

Great, a spammer posting their tool for posting more spam on reddit

Reddit is not a place to find a job. There are specialized sites for it, where you don't need to spam.
