How it works.

River finds this month’s posts where people describe the problem you solve or ask what to use, reads each community’s rules and drafts a reply that properly helps before it says who you are.

  1. Say it the way customers do

    River drafts the phrases your customers use for the problem, from your calls, support mail and site.

  2. River combs the communities

    The last 30 days on Reddit, Hacker News, Indie Hackers, niche forums and your Slack and Discord groups.

  3. Helpful replies go up

    Three to six sentences each, posted one at a time after your yes and checked in the right thread.

What you get.

  • A Problem posts Sheet with every thread, the key sentence and why it fits
  • A disclosed, genuinely useful reply on each thread, never the same text twice
  • Messages only where someone invited one, plus a weekly check for new threads

A few things to know.

Will moderators take the replies down?

River reads each community’s rules first. Where promotion isn’t welcome the reply is pure help, and where a community bans AI-written comments, River leaves that thread for you to write.

Will it plug my product in every reply?

Only when your product really is the answer, and then it says you’re the founder. Links go in only where the community allows them.

What does it cost?

It uses your plan’s AI credit, like everything else in River. Replies go out from the Reddit, Slack and Discord accounts you already have.
