Questions & Answers

As answered by people managing StackMail and LumiGap.

What makes your product unique?

LumiGap's answer:

LumiGap is not just a poker tracker or a note-taking app. It is an AI vision workspace for poker table recognition: capture the table from your screen, recognize cards, stacks, bets, names, board and pot, correct the results, build datasets, train custom models, and export structured table state for research workflows.

Why should a person choose your product over its competitors?

LumiGap's answer:

Most poker tools focus on hand histories, solvers, or finished analytics. LumiGap focuses on the recognition pipeline itself: screen capture, OCR, Core ML, table-region mapping, annotation, custom datasets, model testing, and export. It is for users who want to build and improve their own AI-powered poker research workflow.

How would you describe the primary audience of your product?

LumiGap's answer:

LumiGap is for advanced poker players, coaches, poker researchers, ML builders, data-driven analysts, and macOS users who want to recognize poker table state visually, create custom datasets, and train models for their own layouts and research needs.

What's the story behind your product?

LumiGap's answer:

LumiGap started from a simple gap: serious poker work often depends on screenshots, manual notes, hand histories, and tools that cannot easily be adapted to your own table layouts or model experiments. LumiGap was built to turn visible table states into structured data, datasets, and custom AI recognition workflows.

Which are the primary technologies used for building your product?

LumiGap's answer:

Native macOS stack: Swift, SwiftUI, ScreenCaptureKit, Vision OCR, Core ML, local data storage, annotation tools, dataset converters, external detector support, and live export APIs.

Who are some of the biggest customers of your product?

LumiGap's answer:

  • Advanced poker players
  • Poker coaches
  • Poker researchers
  • ML dataset builders
  • Computer vision experimenters
  • Strategy analysts
  • macOS users building custom recognition workflows
