Visit site ↗Alternativestop 21% of December 2025

What it does

Free, professional dataset annotation tool for editing bounding boxes in images. Supports Pascal VOC XML, YOLO, JSON formats. It lets users load a local folder of images and their XML annotation files (Pascal VOC or custom formats) directly in the browser without uploading anything to a server. Inspect and edit bounding boxes, adjust class labels, delete images, create missing XMLs with configurable mappings, and save changes back to the original files.

    OCR pipeline for ML training (tables, diagrams, math, multilingual)2025 · github.com · ▲170

Some features: • Multi-stage OCR combining DocLayout-YOLO, Google Vision, MathPix, and Gemini Pro Vision • Extracts and understands diagrams, tables, LaTeX-style math, and multilingual text (Japanese/Korean/English) • Highly tuned for ML training pipelines, including dataset generation and…

    Open-source .docx editor library for building document appsMay 2026 · github.com · ▲107

    We are working on an open-source .docx editor library for apps that need to edit Word documents in the browser. We just shipped 1.0. A lot of existing approaches convert .docx into HTML and lose document semantics along the way. Our editor parses OOXML directly and uses its own rendering+layout engine to produce paged documents with html/css. Edits round-trip back to .docx, so you’re always editing the document, not its representation. The core rendering engine is framework agnostic, with React and Vue ui adapters on top. It’s Apache 2.0. Happy to answer questions.

    Community, All the HN belong to you. This is an archive of hacker news that fits in your browser. When I made HN Made of Primes I realized I could probably do this offline sqlite/wasm thing with the whole GBs of archive. The whole dataset. So I tried it, and this is it. Have Hacker News on your device. Go to this repo (https://github.com/DOSAYGO-STUDIO/HackerBook): you can download it. Big Query -> ETL -> npx serve docs - that's it. 20 years of HN arguments and beauty, can be yours forever. So they'll never die. Ever. It's the unkillable static archive of HN and it's…
