Guides & engineering notes
Deep dives on LLM-assisted development, AI model pricing, privacy-first engineering, and how to get the most out of Repo2Txt.
How to prepare your repo for LLMs (and why it matters)
A practical guide to cleaning up your codebase before pasting it into Claude, Gemini, or ChatGPT. Tips on what to include, what to exclude, and how to stay under the context limit.
AI model pricing compared: which LLM is cheapest for your codebase?
Real, verified pricing for 12 latest AI models (Gemini 3 Pro, Claude Opus 4.5, GPT-5.5, DeepSeek V3.2). We break down cost per call, round-trip estimates, and best-value picks for different codebase sizes.
Why client-side tools are the future (and how to verify ours)
Most "AI tools" upload your code to a server. We don't. Here's why client-side architecture matters for developer trust — and how you can verify our claims with your browser's DevTools.
Building Repo2Txt: engineering notes on a 100% client-side tool
How we built a fast, privacy-first codebase exporter that runs entirely in the browser. Covers the File System Access API, binary detection heuristics, gitignore parsing, and performance optimizations.
