Do I need an account to use these?
No. Every tool on this page is fully usable without signing in, and the calculators write your inputs into the page URL so you can share any position or scenario as a plain link. The tools stay free — they exist so the math is available to anyone arguing about a hand.
What does a free account add?
The parts that need your data: hand and session tracking, analytics over your own results, and the Coach — skill drills, daily challenges, and quick spot analysis that adapt to how you play.
AI assistants can use the calculators directly: the MCP endpoint at pokerink.com/api/mcp and the REST API documented at pokerink.com/developers expose the same engines, no account needed.
