A Reddit Marketing Tool That Stays Under the Radar
Most Reddit marketing tools get detected eventually. They use automation patterns that Reddit's anti-spam systems are trained to catch — paste events in comment boxes, robotic cursor movement, cookie-less API calls.
Karma Builder takes a different approach. Instead of trying to automate your entire presence, it gives you AI drafts that you review and approve. When you click "Type It," the extension types each character one at a time — with realistic QWERTY timing, occasional typos that get backspace-corrected, and mouse movement that follows natural Bezier curves. To Reddit, it looks exactly like a human typing.
This matters whether you're a marketer building brand presence, an agency managing client accounts, or a founder growing a community. Reddit users are notoriously hostile to obvious marketing — but they respond to genuine participation. Karma Builder helps you do the second one at scale.
Getting Started
Install from the Chrome Web Store
Click "Add to Chrome" on the Chrome Web Store listing. The extension installs in a few seconds — no restart needed.
Open any Reddit thread
Navigate to reddit.com and find a post or comment you want to reply to. Works on any subreddit, any thread depth.
Click the Karma Builder icon
The extension reads the thread context, generates three comment options, and lets you pick one. Edit if you want, then hit "Type It" to post.
What the Extension Includes
Full Thread Context
Reads the post title, body, parent comments, and existing replies before drafting anything. Every suggestion is anchored to the actual conversation.
Three Options Per Thread
Each generation gives you three drafts with different angles. Pick the best fit, or regenerate for a fresh set.
Four Tone Presets
Professional, Casual, Concise, or Friendly. Switch between them to match whatever subreddit you're in.
Stealth Interaction Engine
Simulates physical human interaction in real-time. Employs N-degree Bernstein trajectories, organic easing speeds, and orthogonal micro-tremors. Comments are typed key-by-key with realistic delays and typo corrections rather than pasted.
Posts & Comments
Works on top-level post replies, nested comments, and deep reply chains. The extension adapts to wherever you are in the thread.
Privacy-First
Your Reddit cookies and session stay separate from AI processing. Comment generation happens server-side through encrypted connections.
