I Built an AI Coat of Arms Maker for Custom Crests and Fantasy Emblems

I’ve always liked the visual language of heraldry: shields, animals, symbols, colors, banners, and mottos that can tell a whole story in a single image. The problem is that creating a good coat of arms from scratch usually takes either design experience or a lot of time. So I built Coat of Arms Maker, an AI-powered tool that turns a plain-language description into an original heraldic design in s...

A 50-capability map for governed web crawling and AI agents

Giving an agent “web access” sounds like one feature. In practice, it is a stack of separate decisions: How does the system discover URLs? Which destinations can it contact? Does it need a browser, or is static HTTP enough? What turns the response into agent-ready data? Where are request, byte, depth, and time limits enforced? What evidence comes back with the extracted content? Treating all o...

When is it safe to open the microphone? Building a realtime voice agent on Twilio

Wiring up a phone agent looks like a weekend project. Twilio Media Streams gives you a WebSocket with raw audio, you push it into a streaming STT, you feed the transcript to an LLM, you stream the reply into a TTS and send the bytes back. A few hundred lines. It works on the first call. Then you listen to a recording and the agent is talking to itself. Agent: "Hello, how can I help you?" STT:...

Programmatic SEO in 2026: How to Scale by Role and Market for AI Search (AEO)

TL;DR: Traditional Programmatic SEO (pSEO) is dead in 2026. To survive Answer Engine Optimization (AEO) and Generative Search, brands must build “Role x Market” page matrices enriched with proprietary “Deep Web” data. By combining localized compliance data, persona-specific pain points, and robust JSON-LD schema, companies can create pages that AI search engines are forced to cite, driving high-in...

Nobody Designs for 2G. Here's What Building in Kenya Taught Me About "Fast" Websites

Most performance advice online assumes a baseline that doesn't exist for most of the world. Fast wifi, a recent phone, a stable connection. Lighthouse scores optimized for conditions half the planet doesn't have. I build web products for businesses in Kenya. A meaningful share of my users are on 3G, sometimes 2G, often on a budget Android phone with limited storage and a browser that hasn't seen ...

Can a Cheap Model Beat a Frontier Model? Rebuilding Recursive Language Models with Codex

Large language models have enormous context windows now. That does not mean they use all of that context reliably. As prompts grow, models can miss details, lose track of relationships, or produce plausible summaries instead of doing the exhaustive work a question requires. The Recursive Language Models (RLM) paper proposes a different interface: keep the large context outside the model, expose i...
