The AI rewrote his 2010 student game in a new language and ported it to Android
The AI with Opus 5 rewrote his 2010 student C game in Common Lisp with SDL2 and OpenGL renderers, running great on Linux and Windows, then ported it to Android as well.
A random mix from the whole library. Shuffle for a new set.

He used AI 4 Argon in Antigravity CLI to run his network and system administration. It bought the domain and set up the full infrastructure, with hosting for a landing page, email, DNS, SSL certificates and hardening.
The AI built him a custom browser with the DNS override feature he always wanted
The AI created a custom Firefox build with a curl --resolve style SSL and DNS override feature he wanted.
LLM renderings and machine code produced his one-off flat-pack furniture
Uses an LLM to generate furniture renderings and CNC gcode, cut and assembled IKEA-style one-off custom furniture.
The AI runs my Bluesky queue in Postiz. I approve every draft.
He plans his Bluesky posts in a self-hosted Postiz and has connected it to the AI through MCP. He can ask the AI to list the queue and add new drafts, and he approves the drafts himself.
69-year-old's three daily the AI routines: a midnight cross-AI journal, a morning briefing and a secretary compliance audit
A 69-year-old Japanese diarist who describes himself as not good with computers runs three daily routines on the AI: a 'Nightly the AI Summary' at 00:08 that compiles his day (including what he consulted the AI about), a morning briefing that organizes his schedule, and a compliance audit of the AI secretary itself. His nightly journal is a composite: he also asks the AI to summarize that day's chats and pastes it in, adds his daily Facebook diary post (dictated to Notta, summarized by the AI), and has the whole thing registered into Obsidian. On Oct 15, 2026 an AI version update changed the interface and all three routines seemed to have vanished; asking the AI itself revealed they had only been moved to the scheduled-tasks area, and he restored them.
This only partly worked. Worth knowing before you try it.
The AI helped me design a monitor mount and I printed it to fit
He wanted a control monitor to fit under his screen and follow the angle and shape of his Stream Deck. He uses AI with reference photos to get the base shape, adjusts sizes after measuring with a caliper, printed a quick baseplate to test the fit, and fixed a 1mm clearance problem with the lock after more measuring.
Watch my other agents and email me when one of them fails to send
Kranda's Monday and Wednesday sprint reports are sent by agents, so he had the AI build a watchdog whose only job is to notice when one of those emails does not go out and email him what happened. He says the watchdog exists mainly because the AI’s device permission issues make silent failures a real risk.
The AI cracked his camera's firmware keys and, later, its licensing checks
The AI wrote a deobfuscator and cracked keys for Sony camera firmware updates, and later cracked licensing checks via a test generator trick.
The AI builds a full AI grader for a teacher grading 100+ papers a week
Liang Gou wrote no code himself: he directed the AI to design and build a complete grading app for his wife, a high school math teacher grading 100+ papers a week at 3 to 5 hours per test. The rubric engine reconstructs a rubric from a single graded example, its eval bank comes from real AP Calculus AB free-response exams, two models cross-check grades, and the agent tested the app itself in a browser before deployment.
