JSON to TOON Converter

What it does

As an indie developer building AI-powered tools, I've been frustrated with skyrocketing LLM costs. Every extra token from bloated JSON in prompts adds up fast – especially when working with structured data for GPT, Claude, Grok, or any large language model. That's why I created JSON to TOON (Token Oriented Object Notation) converter- a smart converter with real time preview, error detection for invalid JSON, handles large datasets, nested structures, and 100% client-side.

Convert JSON to TOON (Token Oriented Object Notation) online. Save up to 40% LLM token usage with real-time compaction, syntax highlighting, and offline support.

  Why write code if the LLM can just do the thing? (web app experiment)Nov 2025 · github.com · ▲436

  I spent a few hours last weekend testing whether AI can replace code by executing directly. Built a contact manager where every HTTP request goes to an LLM with three tools: database (SQLite), webResponse (HTML/JSON/JS), and updateMemory (feedback). No routes, no controllers, no business logic. The AI designs schemas on first request, generates UIs from paths alone, and evolves based on natural language feedback. It works—forms submit, data persists, APIs return JSON—but it's catastrophically slow (30-60s per request), absurdly expensive ($0.05/request), and has zero UI…

  22 GB of Hacker News in SQLite▲730

  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…
