Choosing between GTO Wizard and PioSolver depends on whether you want to consume pre-calculated solutions or build your own. This comparison examines the fundamental differences between a cloud-based training platform and a local desktop specialist tool. It is based on official product information and verified third-party sources as of 18 October 2026. We have not performed independent hands-on testing for this report.
The short answer
If you want immediate access to solutions and a structured training environment, choose GTO Wizard. If you need to build custom decision trees to answer highly specific questions, choose PioSolver.
- The student or busy player: GTO Wizard provides an instant library and interactive trainer.
- The professional researcher: PioSolver offers total control over every variable and tree construction.
- The Mac or mobile learner: GTO Wizard works in any browser and has a free iPhone app.
- The hardware investor: PioSolver rewards a high-core-count Windows machine with speed.
What each one actually is
GTO Wizard
GTO Wizard is a cloud-based platform for studying Game Theory Optimal (GTO) strategy — the mathematically unexploitable way to play. It runs in a web browser on any operating system (Windows, macOS, Linux). The platform gives access to a pre-solved library the company says spans millions of spots across formats, stack depths and bet sizings, plus a trainer where you play against the AI and get reports on correct moves, mistakes and blunders, and hand-history analysis that shows where you lose EV (expected value — the long-term worth of your decisions). Since 31 March 2026 the Cash and Tournament formats have been merged into single subscriptions.
PioSolver
PioSolver is a specialist desktop application from PioSoft. It is local and Windows-only, and it is used to build and solve decision trees from scratch — a decision tree being the map of every possible action (check, bet, raise, fold) through a hand. Where GTO Wizard hands you answers, PioSolver gives you the laboratory to find them: you define the ranges (the hands a player is expected to hold), the board, the stacks and the betting sequences, and the software computes the equilibrium. It has no pre-solved library and no trainer — it is a tool for players who know exactly what they want to ask.
Price and commitment
The two products sit at opposite ends of the financial model: recurring subscription versus one-time ownership.
GTO Wizard (subscription)
- Free tier — a limited daily hand allowance (a third-party source reports around 10 hands per day).
- Starter — $49/month (monthly billing) or $39/month (annual). Since the 2026 update this tier includes weekly coaching sessions and 200+ hours of recorded coaching content.
- Premium / Elite / Ultra — $99 / $169 / $279 per month (monthly billing) or $79 / $139 / $229 per month (annual). Ultra adds custom 3-way postflop and an improved custom preflop tree builder.
Three years of Starter, for illustration: $49 × 36 = $1,764 on monthly billing, or $39 × 36 = $1,404 on annual.
PioSolver (one-time)
- Pro — €450 (plus applicable taxes): flop/turn/river solving with multiple bet sizes, the full PioVIEWER, up to 16 CPU cores, scripting; one year of updates included; two computers.
- Edge — €800 (plus taxes): adds heads-up preflop solving, up to 64 cores, custom hardware compiles, and unlimited moves between the two licensed computers.
Upgrades cost the price difference. The software price is fixed, but the ecosystem is not: solving is CPU-bound, so serious users invest in a high-core-count Windows machine, and complex trees consume real time on it.
What you get and what you don’t
| Feature | GTO Wizard | PioSolver |
|---|---|---|
| Immediate solutions | Yes — a large pre-solved library | No — you build every tree |
| Training mode | Yes — play the AI, get scored | No |
| Hand-history analysis | Yes — finds where you lose EV | No (import histories manually into your own trees) |
| Customization | Within the platform’s parameters | Total — every variable is yours |
| Platform | Web, any OS | Windows desktop only |
| Mobile | Free iPhone app (PokerArena) | No |
| Learning curve | Low to moderate | Steep (commonly described) |
Two honest notes. GTO Wizard’s scope includes tournament work — its study range covers ICM (Independent Chip Model) final tables as well as cash-game spots. And PioSolver’s “no hand-history analysis” is not quite the whole story: it simply has no built-in pipeline for it — a professional will build trees around real spots manually.
Hardware and platform
GTO Wizard — the cloud advantage. The computation happens on the company’s servers; your device needs a modern browser and a stable connection. That makes it the natural choice for Mac, Linux and low-power hardware, and the free PokerArena iPhone app extends study to the phone.
PioSolver — the local specialist. Speed is a function of your CPU: Pro uses up to 16 cores, Edge up to 64, and version 3.10 improved save-file loading and size. The licence is fixed, but the performance ceiling is your hardware’s — which is exactly the kind of control its users want.
Who should pick which
Pick GTO Wizard if:
- You want to start studying immediately, without building trees.
- You value structure: a library, a trainer, coaching content and hand-history analysis in one place.
- You are on a Mac, or you study on a phone sometimes.
- You prefer a subscription you can switch tiers on (or cancel).
Pick PioSolver if:
- You are doing specialist research — precise, unusual spots that a generic library will not contain.
- You want total control of trees, bet sizes, node locks and exploit lines.
- You already own (or will build) a high-core-count Windows machine.
- You want to own the software outright, with scripting for repetitive work.
Many serious players run both: the platform for daily study volume, the local solver for the questions the library cannot answer.
FAQs
Does GTO Wizard work on a Mac? Yes — it is web-based and runs in any modern browser, including on macOS and Linux.
Do I need a powerful computer for GTO Wizard? No. The heavy computation is done on the company’s servers; you need a browser and a stable connection.
Can I use PioSolver on a Mac? No. PioSolver is Windows-only.
Does GTO Wizard have a mobile app? Yes — a free iPhone app called PokerArena.
Does PioSolver include a training mode? No. It is a solving tool; there is no built-in trainer or pre-solved library.
Which is faster to an answer? Different kinds of fast. GTO Wizard returns pre-solved spots instantly. PioSolver’s solve time depends on your hardware and the tree — from minutes for simple spots to long sessions for complex ones.
