Railbird: Describe a hand from memory and get GTO solves + analysis

Hey everyone,

Some of you might have seen my old Reddit post earlier this year about a proof-of-concept AI hand review tool I was building. Since then, I’ve basically rebuilt the whole thing from scratch and wanted to share an update + get feedback from the community because a lot has changed with the app since then.

The project is called Railbird – it allows you to paste/upload a hand history from poker rooms or just describe it from memory

Here are some highlights of the current features:

1. Instant NL Hand Analysis

You can either:

• paste a full hand history (PT4 / HM3 / most standard rooms), or

• just describe a spot in plain English

Railbird will:

• rebuild the hand + game contexts (stacks, positions, board, actions)

• pull GTO-backed strategy from my solver corpus for supported stack depths

• explain those numbers in an easy to digest way so you don't need to memorize solver charts

Examples of things you can type:

“6-max 100bb, CO opens 2.5x, I’m BTN with AKo. 3-bet to 8bb or flat and play post?”

“BTN opens 2.5x, I 3-bet from BB with AKs, flop K72r, turn 5 – did I over-bluff river?”

The aim is to review that one annoying hand after a session without digging through trees or node selectors.

2. Session Reviews in “Story Mode”

You can also upload a full HH file, Railbird builds a complete review:

• 🕒 Timeline view: each hand becomes a short “story card” so you can skim the session and jump to the key pots.

• 📈 Dedicated solver panel: frequencies / EV / ranges live in their own panel, separate from the explanation text.

• 💬 Coach chat: you can ask follow-ups on any decision (e.g. “Why this combo prefers bluffing” / “What’s my defending range?”) inside the review flow.

⸻

Current coverage:

• 🏆 MTT: 20–100bb

• 💵 Cash: 50–150bb

Right now:

• Limped pots are handled by the LLM using heuristics, I plan to add support for these spots soon.

• Multi-way spots are approximated

The whole idea is to bridge the gap between memorising solver outputs and actually understanding why solver prefers certain lines, in a way that can be turned into real-time intuition at the table instead of just memorizing solver output.

Future:

I'm currently working on a desktop app that will automatically imports your hands and allow you to pick the hands/sessions you want to analyze. Do send me a DM if this is something you'd like to test on!

I'd love to hear your feedback on:

- Is it easy to understand what you were supposed to do in the app?

- If the analysis feel useful / trustworthy and smooth?

- Feedback on the explanations: Is it deep enough?

- Ideas for what would make this a tool you’d actually use daily

Thanks guys, happy grinding!

Describing a hand from memory is a great idea for live players. Most of my live hands only exist in my head. One question: how does Railbird handle a description that's slightly wrong? From memory I'm usually sure about my cards, the board and the big bets, but not about exact stack sizes or who limped. Does it ask follow-up questions, or does it just assume defaults?
