Local Whisper pipeline beats paid Korean transcription services

We were paying for Notta to transcribe Korean meetings. The Korean accuracy on technical terms was consistently bad — we were spending more time fixing transcripts than just writing notes by hand. So we built a local Whisper pipeline. Turns out it beats the paid service on Korean accuracy. 📚 Full writeup: https://treesoop.com/blog/whisper-transcription-local-korean-stt-2026 🔧 GitHub: https://git...

How to Defend Your AI Agent Against Prompt Injection

Your AI agent is an attack surface. Every tool connection is a potential blast radius multiplier. Every document it processes is an untrusted input channel. Here's how to lock it down before something goes wrong. The Problem Prompt injection is what happens when an attacker embeds instructions inside content your agent is supposed to read as data. The agent can't reliably tell the difference — i...

Stop burning tokens on DOM noise: a Playwright MCP optimizer layer

If you've used Playwright MCP for AI browser automation, you know the pain. Every page navigation dumps the full DOM tree into the model context. Simple flows like "order 5 items from this shop" can burn hundreds of thousands of tokens on navbar/sidebar/footer noise that has nothing to do with the task. We built a small MCP layer that sits in front of Playwright and only forwards the relevant bit...

ai-news-mcp: 17 AI trend sources auto-scraped, served via MCP

Keeping up with AI news means scraping the same sources as everyone else — HackerNews, Reddit (r/MachineLearning, r/LocalLLaMA), ArXiv, GitHub Trending, Dev.to, Lobsters, and about 10 more. Everyone builds their own version. Seems silly. So we built one and open sourced it. 📚 Full writeup: https://treesoop.com/blog/ai-news-mcp-17-sources-auto-scraping-2026 🔧 GitHub: https://github.com/treesoop/a...

Why I built ragwise: pip-installable RAG with hybrid search, streaming, and agent tools by default

Why I built ragwise: pip-installable RAG with hybrid search, streaming, and agent tools by default

I spent a weekend integrating a RAG pipeline into a client project using LangChain. By Sunday evening I had 200 lines of boilerplate, a requirements.txt with 47 packages, and retrieval quality that was noticeably worse than I knew it could be. Not because LangChain is bad. Because I'd made the same mistake everyone makes: I left dense-only search as the default. Dense search misses exact keyword...

Why I built procscope instead of just using Tracee or Falco

If you work in cloud security, you are probably exhausted by the acronym soup of eBPF tools. From Sysdig's Falco to Aqua's Tracee and Isovalent's Tetragon, the market is flooded with "Kernel-Level Observability" daemons. So why on earth did I write procscope? Because enterprise EDRs are built for fleets, not for incident responders. The Signal-to-Noise Problem When I get paged becaus...

Introducing hwp-mcp: Korean document support for Claude via MCP

Korean office documents (.hwp / .hwpx) are everywhere in Korean government, enterprise, and legal workflows. Until now, Claude, ChatGPT, and Cursor couldn't read them natively — a real blocker for anyone building AI systems for Korean organizations. We (TreeSoop) just released hwp-mcp, an open source MCP server that fixes this. 📚 Full writeup: https://treesoop.com/blog/hwp-mcp-korean-document-ai...

How Voice Data Travels: With Internet vs Without Internet 📞🌐

A developer's deep dive into what actually happens when you make a phone call So you're building a voice call feature in your app. You pick up a library, maybe WebRTC or a third-party SDK, and things just... work. But then a question hits you mid-implementation: "Wait — how is voice data actually being sent? And how is this different from a regular phone call?" That exact thought led me down...

Hot take: most "AI-powered" products are just regular products with an API call in the middle

That's not a diss. It's where most teams start. But there's a real gap between wiring up an LLM and actually building a system that learns from its environment, adapts to changing conditions, and doesn't quietly rot the moment your data drifts. This is where product engineering starts to matter, especially when AI systems move from experimentation to production. AI-driven product engineering is ...
