PeakGTO is the cheapest No-Limit Hold’em GTO solver on the market right now, and for tournament grinders below mid-stakes it pays for itself inside two months.

The tool is built by PokerCoaching.com, the training brand of two-time WPT champion Jonathan Little. It launched in October 2025, and our team added it to the broader poker tools we track the day it went live.

Our review is the result of 30 days of using the tool in our daily routine across MTTs and 100bb cash. We tested it against the same spots in GTO Wizard and PioSolver.

What Is PeakGTO?

PeakGTO is a cloud-based study tool for No-Limit Texas Hold’em. It provides pre-solved GTO spots within the following five modules: The Library, The Trainer, Drills, Drill of the Day, and Poker ELO.

It runs on any browser without installation and supports eight-max tables. It covers both MTT and cash game formats. GTO is an unbeatable strategy, even against a perfect opponent.

Professional poker players produce solutions using three industry-standard engines. Preflop work uses the Holdem Resource Calculator and MonkerSolver, and postflop work uses PioSolver.

If you want a wider primer on solver mechanics before diving in, our GTO and solvers explainer covers the fundamentals.

PeakGTO Pricing

PeakGTO offers three tiers: a free plan, a $79/mo monthly plan, and a $59/mo annual plan (billed yearly at $708 total).

The annual plan saves you $240 per year compared to paying monthly. Both paid plans eliminate daily usage limits and allow you to use every module as much as you want.

Free Tier Limits

The free tier never expires and includes 10 Library spots per day, 10 Trainer spots per day, 10 Drills per day, and 1 Drill of the Day. The ELO score works on the free tier as well, so progress tracking is not gated.

Breakeven Math for Grinders

PeakGTO costs $708 per year on the annual plan. If the tool removes 0.5 BB/100 of EV-loss from your game (a conservative gain for a solver-naive player), an NL50 grinder playing 30,000 hands per month recovers the subscription cost in roughly two months of normal volume. At NL100, the breakeven hits in roughly four weeks.

PeakGTO Solver Data Quality

For any solver buyer, peak GTO data accuracy is the single most important question, and it publishes specific numbers for every engine in its stack.

The preflop data is solved using Holdem Resource Calculator (HRC) and MonkerSolver, with HRC convergence below CI = 5 and ICM data below CI = 2.

CI stands for Convergence Index and measures how close a solve sits to a true Nash equilibrium, where lower values are more accurate.

Postflop Engine

The software uses PioSolver for every postflop spot, with all data run through CFR (Counterfactual Regret Minimization) based modeling.

Exploitability falls between 0.25% and 0.5% of pot depending on tree size, with the tightest solves on shallow stack-to-pot-ratio boards.

Exploitability measures how much an opponent can gain against a strategy if they play perfectly. It is expressed as a percentage of the pot, and anything under 1% is considered tournament-grade.

Database Scope

As the table below breaks down, coverage is deepest for MTT preflop and narrows across the other three categories.

The Four PeakGTO Modules in Action

PeakGTO divides the study process into four main modules and uses an ELO scoring system. Each module focuses on a different aspect of GTO learning, ranging from basic lookup to active recall.

The Library is a pre-solved spot browser. You select the position, the action sequence, the stack depth, and the board, and it instantly returns the full GTO output.

This replaces a custom PioSolver simulation that would otherwise take several minutes on a desktop computer.

The Trainer is the active recall engine. You set the parameters and click start. Then, PeakGTO presents you with random matching scenarios while showing your EV loss per decision in real time.

EV-loss is the BB difference between your chosen action and the GTO-optimal action.

For inline math during study, our poker equity calculator pairs naturally with the Trainer.

PeakGTO vs GTO Wizard, GTO Lab, and PioSolver

PeakGTO is not the only solver on the market in 2026, and the buy decision depends on what you compare it to.

The shortlist is GTO Wizard (the category leader on depth), GTO Lab (the ICM-focused option), PioSolver (the legacy desktop heavyweight), and Octopi Poker (the most beginner-friendly).

PeakGTO wins on price and learning curve, especially for MTT players who want preflop coverage down to 2bb.

GTO Wizard wins on raw depth, with multi-way 3-way solves shipped in 2025 that PeakGTO has not yet matched. PioSolver still wins for high-stakes pros who need to build custom solves with their own bet trees.

Our 30-Day PeakGTO Study Workflow

PeakGTO works best with a fixed weekly schedule, rather than being opened on impulse.

We tested the tool across 30 days of MTT and NL100 cash games grinding on CoinPoker and GGPoker, tracking ELO and EV-loss across roughly 24,000 hands. The workflow below is what produced our largest weekly ELO jumps.

The single highest-leverage habit was the daily 15-minute Drill of the Day, which works on the free tier and never runs out.

The Saturday Library deep-dive on the two specific seats we played most last week consistently surfaced 2 to 3 patterns we had been butchering for months.

Post-session review is where most players drop the workflow. After every grinding session we pulled the three hands with the worst EV-loss and replayed them inside the Trainer module.

This converted hand-history regret into measurable EV recovery within one week.

Can you use PeakGTO for your poker room?

PeakGTO is a study-only tool, and every major poker room treats solver use during play as bannable.

Real-time assistance (RTA) is the term for any tool that feeds GTO answers to a player during a live hand. PeakGTO’s own terms of service explicitly prohibit using the app while seated at any cash game or tournament.

The risk is real and the penalty is severe. Account suspension, fund forfeiture, and permanent bans across all linked accounts are the standard outcomes when an operator detects RTA usage.

Detection methods include session-timing analysis, mouse-movement profiling, and second-screen forensics on shared networks.

PeakGTO Limitations You Should Know Before Subscribing

PeakGTO covers a narrow slice of poker very well, and a clear-eyed look at the gaps will save buyers from a refund request 30 days in.

The biggest single limitation is game variety: PeakGTO is No-Limit Hold’em only and has no PLO, PLO5, Short Deck, or mixed-game coverage on its public roadmap.

Format coverage is the second gap. It solves 8-max only, which is a clean fit for live MTTs but mismatched for 6-max online cash regs.

The same range structures broadly transfer, but pot-share frequencies shift enough at 6-max that the data is not a direct one-to-one.

Cash game players also lose depth coverage past 100bb. Live $5/$10 regs running 250bb effective on a soft table will not find their exact spot inside the postflop database.

Conclusion: Who Should Subscribe to PeakGTO in 2026?

PeakGTO is the right buy for a specific profile and the wrong buy for everyone else. The cost is low enough that the decision comes down to game choice and stake more than budget.

Buy the annual plan if you grind MTTs with an average buy-in of $5 or higher, or play NL100+ cash, or run live $2/$5 and higher.

Use the free tier if you play below NL25 cash or under $2 ABI MTTs, because the daily caps cover what you can realistically absorb. Skip PeakGTO entirely if your main game is PLO, Short Deck, or any mixed format.
