I built ThreadFit because Reddit is where customers actually show up. People with a real problem don't search for ads, they ask Reddit: "what do you use for this?" Those threads rank on Google and get quoted in AI answers for years. And someone asking for a recommendation is already halfway to buying.
The hard part was never knowing that. It was finding those threads in time, and replying without sounding like a spammer. So I built a tool that finds them, tells me why each one fits, and helps me write a reply I'd be happy to post under my own name.

"Won't I get banned for promoting on Reddit?"
Not if you do it the way Reddit expects: help first, disclose that it's yours, and follow each subreddit's rules. ThreadFit is built around exactly that.
- It never posts for youNo bots, no auto-comments, nothing done in your name. It only reads Reddit. You read, edit and post every reply.
- Rules before repliesEach subreddit's rules are read and shown, and drafts drop links where they're banned.
- A pace that looks humanA timer between replies, and a reminder when you've replied a lot in a short time.
- Disclosure built inEvery draft that names your product says plainly that it's yours.

Questions people ask
What does ThreadFit actually do?
It reads the newest posts in the subreddits you choose and across Reddit search, finds the ones where your product could genuinely help, scores each for buying intent, and drafts a reply. You edit the reply and post it yourself on Reddit.
Does it post or comment for me?
No, never. It has no way to post, comment or vote. Every reply is yours to read, change and post.
Do I need an AI key? Does it cost anything?
ThreadFit is free. For AI drafts you add your own key from Google Gemini, Groq or Anthropic Claude. Gemini and Groq have free tiers, and you can add more than one key so the next one takes over if one is busy.
Will I get banned?
Reddit bans spam, not helpful people. Answer the question first, say the product is yours, follow each subreddit's rules, and keep most of your comments free of self-promotion. ThreadFit shows the rules, adds the disclosure and spaces out your replies, but how you post is up to you.
Which browsers does it work in?
Chrome on a computer (it uses Chrome's side panel). Keep a reddit.com tab open and be logged in to Reddit.
Is it made by Reddit?
No. ThreadFit is an independent tool, not made, endorsed or sponsored by Reddit.
