Flyzio monitors Reddit for threads where your product belongs, writes contextual replies that sound like you wrote them, and posts safely — so you stay focused on building.

“Got two signups from a single comment on r/personalfinance. Never would have found that thread manually.”
“I spent 3 hours a week on Reddit before this. Now it takes 10 minutes to review and approve queued replies.”
“The safety limits are what sold me. I was terrified of getting shadowbanned. Haven't had a single issue.”
Three steps from install to organic growth.
Add the keywords your audience uses and the subreddits they hang out in. Flyzio scans them every hour and surfaces threads where your reply adds real value.
Flyzio generates a contextual reply draft for each matched thread. You read it, tweak the wording, and approve — or let it run on schedule.
Score, upvotes, and reply count tracked for 7 days after posting. See exactly which comments land and which threads drive signups.
Built for founders who want organic traction without living on Reddit.
No Reddit API keys required. Posts are made through your logged-in Chrome session — indistinguishable from a real person browsing.
3 replies/day, 90-minute minimum gaps between posts. These limits are hardcoded — not a setting you can accidentally disable.
Replies are generated fresh from the thread content, your product description, and your voice settings. No templates, no copy-paste.
Score and reply count tracked for 7 days after posting. See which comments drove traffic and which subreddits convert best.
Every scan, every queued reply, every post — logged locally and optionally synced. Build your growth audit trail from day one.
Monitor up to 20 subreddits at once. Hot-keyword scoring puts the highest-intent threads at the top of your queue.

I built RetireRangers to help German ETF investors with retirement planning. The problem was nobody knew it existed. I didn't want to run ads. I tried posting on Reddit manually but it felt spammy and took hours.
I ran Flyzio for one week. It found 205 relevant threads across r/Finanzen, r/personalfinance, and r/ETFs. I posted 3 replies — each one read and edited before posting. One got upvoted and drove 4 profile visits. That week we got our first organic sign-up from Reddit, directly tracked back to a comment.
Read the full breakdown →The extension posts through your existing logged-in Reddit session using normal browser actions — not the API. This is the same as you typing a reply yourself. The built-in rate limits (max 3 replies/day, 90-min gaps) keep velocity low. We've been running this on a live account for weeks with zero issues.
Flyzio reads the thread title and top comments, then generates a reply tailored to that specific conversation using your product description and voice settings. Every reply is unique to the thread — no templates. You always review before anything gets posted.
No. Flyzio uses your browser session, not the Reddit API. You just install the extension, log into Reddit normally, and Flyzio handles the rest.
Niche communities where people ask for recommendations tend to convert best — r/personalfinance, r/SideProject, r/Entrepreneur, niche hobby/interest subs relevant to your product. Broad subs like r/technology rarely convert well.
Lead data and settings are stored locally in your browser's IndexedDB — on your own machine. Activity can optionally sync to our backend when you have a license key, but that's opt-in. You can export everything as a JSON file at any time.
Free to install. No card required. Takes 2 minutes to set up.
