Show HN: Axiom – structural OCR for handwritten STEM notes (www.useaxiomnotes.com)

Axiom has announced a groundbreaking structural OCR tool specifically designed for handwritten STEM notes, enabling users to convert their math, physics, and chemistry notes directly into clean LaTeX and Markdown formats. Unlike traditional OCR solutions, which can struggle with mathematical notation and often rely on pixel-based recognition, Axiom utilizes structure-aware recognition to preserve the logic and integrity of written equations. This innovative approach not only eliminates the need for retyping but significantly reduces the risk of errors that can arise from standard transcription methods. The significance of Axiom lies in its focus on long-term accessibility and data ownership. By outputting in LaTeX and Markdown—universal, plain-text formats that remain readable over decades—the tool ensures that scientific notes can be easily reorganized and searched without losing precision. Users benefit from a pay-per-page pricing model, which avoids recurring subscriptions and protects their data privacy with a local-first approach that retains no information. Axiom aims to safeguard the permanence of digital notes in an era where proprietary formats and subscription services often threaten the lifespan of critical academic work.
