Solving Reddit Automation: Browser-based agent with AI Vision

Hey everyone,

I wanted to share a project I’ve been running for a few weeks now. Most people who try to automate Reddit eventually hit a wall with the API or get banned almost immediately. I decided to take a different approach: Browser Automation.

How it works: Instead of calling endpoints, the script operates like a human user.

For Comments: It iterates through a list of subreddits, opens the latest post, and takes a screenshot. That screenshot is sent to an AI Vision model to "read" the context (images, code snippets, or text). The AI then generates a helpful response which the bot types out field-by-field.

For Posting: It analyzes the top 30 posts of a specific subreddit to understand the "vibe" and common flairs. It then generates an original post that fits the community standards.

The Results: I’ve been testing this in technical niches like Webflow, Blender, and Web Development. What surprised me most is that I’m actually getting "Thank you" replies. Because the AI has a deep understanding of the technical problems in the screenshots, it often provides better solutions than I could manually. I’ve been gaining Karma steadily every day without any flags from Reddit.

The Dilemma: While the tech works flawlessly, I’m still figuring out the best "real-world" application for this. Is it just a Karma-builder? A lead-gen tool? Or a way to provide automated support for specific products?

I’d love to hear your thoughts on whether you think this approach is sustainable and what kind of use cases you see for an automation that actually provides value to the readers.
