As answered by people managing GTOKiller and ContextForge.dev.
GTOKiller's answer
GTOkiller is an exploitative solver, not a GTO solver. GTO solvers compute strategies against a theoretically perfect opponent that doesn't exist in real games. GTOkiller computes the strategy that maximizes EV against the way your player pool actually plays, measured with Mass Data Analysis across millions of real hands. The exploitative layer is applied to the entire game tree simultaneously, and every deviation is auditable: you see the GTO baseline, the real population frequencies, and the exploit side by side.
ContextForge.dev's answer:
ContextForge is memory that lives at the MCP layer, so it works across every AI coding agent at once — Claude Code, Cursor, GitHub Copilot, ChatGPT, and Windsurf — not just one. Save a decision once and any client recalls it later with semantic search. It goes beyond a note store: automatic git sync turns your commits and PRs into searchable knowledge, plus task tracking, snapshots, and team sharing — all through a single MCP server you add with one command.
GTOKiller's answer
GTOkiller was built by a small team of poker players and engineers in Spain who kept running into the same wall: hours of solver study that real opponents simply didn't respect. If the pool doesn't play GTO, a strictly better strategy must exist. They built the engine to compute it: mass data analysis over millions of real hands, turned into full-tree exploitative strategies with every number visible.
ContextForge.dev's answer:
ContextForge was born from a simple frustration: AI coding agents forget everything the moment a session ends. Every new conversation meant re-explaining the same architecture, naming conventions, and past decisions. ContextForge was built to give AI agents a permanent, searchable memory through the Model Context Protocol — so knowledge is captured once and reused forever, across sessions and projects. It even dogfoods its own memory to help build itself.
GTOKiller's answer
Compared to GTO solvers (GTO Wizard, PioSOLVER, GTO+): they teach you to play against an opponent that doesn't exist. Their exploitative features rely on manual nodelocking, which is theoretical, biased by your own assumptions, and limited to one node at a time. GTOkiller applies real population data to the full tree automatically, at roughly half the price of GTO Wizard's top tier.
ContextForge.dev's answer:
Most memory tools are tied to a single agent or are just a key-value store. ContextForge is MCP-native, so it's portable across all your AI tools; it adds git sync so your codebase history becomes searchable context automatically; and it includes team features (shared spaces, collaborators) that solo-memory tools lack. Setup is one command, there's a genuine free-forever tier with no credit card, and paid plans start at just $9/month.
GTOKiller's answer
A proprietary solving engine and a Mass Data Analysis pipeline processing millions of hands per pool, served through a web app built on Next.js and Google Cloud.
ContextForge.dev's answer:
Next.js 16 (App Router), React and Tailwind CSS for the dashboard, hosted on Vercel. Supabase (PostgreSQL) with pgvector powers the semantic vector search, and Deno edge functions serve the API. Embeddings use OpenAI text-embedding-3-small. The MCP client is a Node.js package (contextforge-mcp) on npm, implementing the Model Context Protocol.
GTOKiller's answer
Individual online cash game professionals and regulars across Europe, North America and Latin America
GTOKiller's answer
Online cash game regulars at low and mid stakes (NL10 to NL100) who already study with solvers but feel their study doesn't translate into winrate, because their pools don't play anything close to GTO. Today the population data covers GG Poker NL10 to NL50; since leaks depend more on the stake than on the site, players at the same stakes on other sites use it as a close proxy.
ContextForge.dev's answer:
Software developers and engineering teams who use AI coding assistants — Claude Code, Cursor, GitHub Copilot, ChatGPT, Windsurf — and are tired of re-explaining their project, architecture, and conventions every session. It fits solo developers working across multiple projects as well as small teams that need shared, persistent context.
