What you get

Plans, tracks, writes β€” and gets better every time you use it.

πŸ“…

Plans

GrowPost builds your posting plan: what to write, where, and when β€” timed to your own clock, not a generic best-practice guess.

πŸ”Ž

Tracks

Your keywords, subreddits, and X accounts are watched around the clock. Every relevant thread or tweet arrives as a ready-to-paste reply.

✍️

Creates

Every post and reply is written for you β€” specific to the thread, in your voice. No templates, nothing that reads like a bot.

🧠

Adapts

Tell it what to change β€” "focus more on r/Notion", "stop mentioning pricing" β€” in plain English, and it remembers going forward. Not a fixed set of rules, a strategy that learns from what actually worked.

How it works

We find, draft, and learn. You post.

πŸ”­

1. GrowPost watches

Continuous monitoring of your subreddits, keywords, and X accounts. New threads and tweets are scored for relevance the moment they appear.

GrowPost does this
✍️

2. GrowPost drafts

Each opportunity arrives with a ready-to-edit reply shaped by what's actually worked for you before β€” not a fixed template β€” and flags subreddit rules like "I will not promote".

GrowPost does this
πŸ™‹

3. You post

You review, tweak and post from your own account. Real replies from a real person β€” the only kind Reddit and X actually reward.

You do this

Why manual posting wins

Bots get banned. Generic tools get ignored.

πŸ€– Auto-posting & template tools

  • Accounts flagged and suspended by Reddit's antispam
  • Same generic script for every product, never adjusts
  • Subreddit rules ignored β€” posts removed by mods
  • Your brand attached to spam you never reviewed

πŸ‘€ GrowPost

  • You post from your own account, on your terms
  • Drafts written per thread, edited by you
  • Learns from what's worked and adjusts as you go
  • Subreddit rules surfaced before you reply
