Hi HN,

I’ve been working on an OCR pipeline specifically optimized for machine learning dataset preparation. It’s designed to process complex academic materials — including math formulas, tables, figures, and multilingual text — and output clean, structured formats like JSON and Markdown.

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 preprocessing for RAG or fine-tuning tasks

Sample outputs and real exam-based examples are included (EJU Biology, UTokyo Math, etc.) Would love to hear any feedback or ideas for improvement.

Hello,

I built this project mostly through vibe coding—it’s designed for people who don’t have time to monitor the crypto market daily.

The software lets you add all the cryptos you want to monitor (including your portfolio) and sends you a daily newsletter with updates, AI suggestions, trading signals, and analysis. You can also easily set price alerts.

On the dashboard, you can chat with the AI about the cryptos you’re following.

One of my favorite features is the “suggest a new token” tool—it uses news to recommend tokens, and sometimes the suggestions are surprisingly interesting.

Let me know what you think! It’s free to monitor up to 5 cryptos.

Have a great day!

We've developed PokemonGym, an open-source benchmark that uses Pokemon gameplay to evaluate LLM capabilities in tool use, information extraction, and reasoning.

The benchmark features 387 carefully designed milestones (reaching locations, catching Pokemon, earning badges) with assigned difficulty scores to create a standardized evaluation framework.

Our initial testing revealed an interesting performance gap: amateur human players require ~400 steps to catch their first Pokemon, while Claude 3.7 needs ~450 steps - suggesting AI models are approaching human-level performance in this domain.

The benchmark will soon be available on benchflow.ai with a simple API for testing your own agents and models.

GitHub repo: https://github.com/benchflow-ai/pokemon-gym

We're looking for collaborators interested in improving the harness or running experiments with different models.
