Current Focus

What you can open now: the browser tools, Sayo, CrossAgent Lab, and this site.

SayoLive Spoken English practice built around core verbs, real-life scenes, and another try in a new scene. Say it yourself first, then look at the hint if you get stuck.

Docs & in progress

These pages explain the idea. The repos are still private, so you get a write-up, not a demo you can run.

Agent WorkstationPrivate docs A write-up of a multi-agent workflow. The repo is still private. This page explains the design; it is not a public demo. Agent WorkflowDocsPrivate repo Ebook FactoryPrivate docs A write-up of a Markdown-to-ebook pipeline. The repo is still private because it may contain real book material. PublishingDocsPrivate repo

AI / Agent Engineering

GitHub experiments around tool calling, browser automation, RAG, and research workflows. You can open the repos. They are not products you can use.

MCP Screenshot InverterExperimental An MCP + Puppeteer experiment for browser screenshots and tool-calling workflows. MCPPuppeteerBrowser Crawler AI ChromeExperimental A Chrome extension experiment for collecting public Twitter / X content for AI-assisted research and creator-operation workflows. Chrome ExtensionResearchCreator Ops RAG Search APIReference A forked / reference-based RAG backend learning experiment, useful for learning and internal exploration but not positioned as an original flagship project. RAGBackendReference

Frontend Infrastructure

This is the engineering base: schema-driven UI, frontend knowledge archives, and older experiments that still explain how I think about systems.

schema-renderExperimental A schema-driven UI rendering experiment for dynamic frontend interfaces. It belongs to low-code, dynamic forms, admin systems, and frontend architecture abstraction — not AI by itself. Schema UILow-codeFrontend Frontend MapArchive A historical frontend knowledge archive covering JavaScript, TypeScript, Vue, and frontend engineering. It records the engineering base behind my current AI and full-stack experiments. FrontendJavaScriptTypeScript Frontend Engineering ArchiveArchive Earlier frontend engineering experiments and notes, including front-end-architecture, component-doc, shared-state-management, simple-hmr, and webpack-build.

Creator & Media Tools

Experiments for content production and video editing. The cover tool you can open is above. These are repos, not finished products.

AIContent OpsXiaohongshu CapCut Audio Subtitle AlignExperimental A creator-workflow experiment for aligning audio and subtitles in editing pipelines, especially useful when turning AI-generated or edited media into short-form content.
