What this page is
This page quotes r/secondbrain's rules as ThreadFox read them on 2026-10-13. The quoted text is the community's; the verdict above is our reading of it. Conditions often decide whether a post fits (a required thread, flair, posting day, account age or karma), and r/secondbrain's current rules on Reddit always win over this page.
Free, for a specific product: a researched Reddit plan by email (communities whose rules fit your post, quoted and dated), or ThreadFox Lite, read-only tools an AI assistant can use to read a community's current rules itself, through your own Chrome (Claude Code: claude mcp add threadfox-lite -- uvx threadfox-lite). For an assistant that also writes and posts within each community's rules, the ThreadFox kit is $49 once.
Want to post here? Get ThreadFox ($49): your AI (Claude Desktop, Claude Code or Codex) reads a community's current rules, writes one post that fits and posts once from your own Chrome. No Claude? We'll post for you ($49 per 30-day campaign). Free: a Reddit launch plan for your product, ThreadFox Lite or the posting checklist by email.

- its rules on Reddit
The Official sub-reddit for Second Brain. A place to discuss tools and methods to create and deploy networks of AI-agents that handle the context in our lives. Sub-reddit was created 10 years ago, but the initial mission was always to have a software that maps the way you think and work.
What its rules say about promotion
Products must have free-tier
If you built some tool you want to share with the community, there must be at least basic features that are not behind a credit-card wall. This is a community of people already using second brain tools, and the conversation should be focused at getting feedback for your product rather than finding paid customers.
No affiliate links
No affiliate links or 'refer-a-friend' codes. Only codes that offer the community free trial or free discounts to your product will be tolerated.

What the written rules don't show
- Unpublished minimums. Many communities remove posts from new or low-karma accounts through AutoModerator settings that are not on the rules page, often before a moderator sees them.
- Reddit's own filters. Reddit's site-wide spam filters can remove posts from accounts that mostly share links to their own site, in any community.
- The community's norms. Many communities see themselves as peers, not an audience: post where you already take part, and make the post worth reading without the link.
Let your AI read the rules before it posts.
ThreadFox reads a community's current rules, writes a post that fits them, posts once with Reddit's Brand affiliate tag and checks it stayed up. The free ThreadFox Lite reads rules too.
