FAQ
What is WhichSub?
A free tool that shows which subreddit (and time) brings you the most traffic, with AI-written captions. You post on Reddit yourself; we measure what actually works.
Do you post to Reddit for me?
No. You post manually, as you already do, and use our tracking links. This keeps your account safe (no automation against Reddit's rules) and lets us measure your clicks.
How does the tracking work?
Each subreddit gets a unique short link that redirects to your destination and logs the click. Your dashboard then ranks subreddits by clicks and best times.
Do I need an OnlyFans or Fansly account?
You just need a destination URL — your OnlyFans, Fansly, or link-in-bio. That's where the tracking links send people.
Where do I put the tracking link on Reddit?
In a comment on your post, or in your Reddit profile's link. Use each subreddit's specific link so we know where the clicks come from.
Can WhichSub see my Reddit or OnlyFans password?
Never. We don't ask for them. We only need your public destination URL.
Is it free?
Yes — the core (tracking, analytics, AI captions) is free. A premium tier with revenue insights and unlimited AI is coming.
Can you tell me which subreddit makes me money?
Not exactly yet — Reddit doesn't pass identity to OnlyFans, so 1:1 dollar attribution isn't possible. The free tier shows clicks; the upcoming Pro correlates your imported earnings with click sources.
Is my data private?
Yes. Your posts and stats are only visible to you, and the database is locked down so no one else can read it.
What are the 'best times to post'?
From your click timestamps we show the hours and days your audience is most active — in your own local time. Tap a day to drill into its hours.
