Metin2 Captcha Solver

Answers in-game anti-bot challenges, with OCR for the rest.

Windows 10 & 11 Private servers

What the captcha solver does

Servers interrupt long sessions with a captcha to catch bots, and an unanswered one ends the run. STMod answers the challenges it recognises on its own, and for the rest there is an OCR Groq captcha solver that reads the image and types the answer.

Before you start

STMod runs inside your Metin2 client: the launcher starts the game and attaches the bot, so its tabs appear as a panel in the game window. You need Windows 10 or 11, the client of a supported server and the AIO runtimes.

Every account can claim a free 24-hour Premium key once, then a 1-hour key daily, so you can test this on your own server before paying anything.

  • "No captcha solver" noticeShown next to the CH Changer box when your server uses a challenge STMod does not recognise — so you know before you leave it running.
  • OCR Groq captcha solverA launcher-wide option that solves server-side captchas through the Groq API. Not available on official servers.
  • Your own API keyNeeds your own free Groq key, pasted under Plugins → Groq API key, which also shows whether the solver is running.
  • PremiumThe checkbox can be ticked on a free account but does nothing without an active subscription.

Every option documented in full on the STMod wiki.

How to set up the captcha solver

  1. Get a free API key from Groq.
  2. In the launcher, open Plugins → Groq API key and paste it in.
  3. Tick OCR Groq captcha solver on the launcher's main window.
  4. Check the plugin page again — it reports whether a key is configured and the solver is running.
  5. Watch for the No captcha solver notice in game, which means your server's challenge is not recognised.
Automation is against the rules of every Metin2 server and accounts do get banned. STMod has detectors and an HWID switcher, but the risk is yours. Use an account you can afford to lose.

Captcha Solver FAQ

Does STMod solve Metin2 captchas?
It answers the challenges it recognises automatically, and the OCR Groq solver covers server-side captchas it does not.
Do I need my own API key?
Yes, your own free Groq key. Keep it to yourself — nobody from STMod will ever ask for it.
Does it work on official servers?
No. The OCR Groq captcha solver is not available on official GameForge servers.
