Ask HN: What are tools you have made for yourself since the advent of AI?

A "Home Agent" setup, with customized special agents to manage various aspects of the house through home assistant, learning feedback from household users to try and tune everything at the right time.

Various MCPs for above.

A "remote claude code server", that gives project level overview and lets me run projects / develop on my home server rather than locally through my laptop. Supports ssh as well as a web UI (projects in a list, shell rendered using https://xtermjs.org/, with a tile overview when working on multiple projects to watch for turn ends.

Similar to above, I have a local version that auto launches a new project scoped podman container, passess through the work directory, installs CC/Codex/Grok into it and passess through the auth / config for each agent. Then dumps you into that shell with aliases to map each agent to that agent with a few special env flags to disable permission prompts, so claude = `claude --dangerously-bypass-permissions`.

An extensive MCP for Obsidian that gives agents access to use a lot of the more advanced Obsidian functionality, such as suggesting and installing plugins / configs / etc.

It's helped some of my daily productivity, but I still prefer to get my hands dirty with code most of the time rather than full prompt it.

I restore old non-functioning radios with nice design and good audio. I replace the old tech except the speakers with a raspberry add a mic array and package them with an easy to use ubuntu. whisper and the small gemma models made everything so much easier and private. I basically rewrite the whole backend with claude and created a nice first setup experience akin to other smartspeakers. It's amazing how good the sound is from these old speakers.

I've always used notepad++ with one single giant .txt file for taking notes with dividers separated for each day so I codified that practice into a desktop app

Just a super minimalist thing where each day is one .txt file with the newest one at the top and a lazy loading scrolling list with every note going back 5 years

Supports CTRL + F searching, backups, and a bunch of other QoL features/macros

Its kind of a revolution that with agentic coding everyone can have their own hyperspecific customized apps

A MacOS desktop app and a mobile app for instrumenting GPS routes.

Working on a web client and bouncer for Hotline, the old chat software from ~1997. Just want to chat with my peeps who still use Hotline, from the comfort of the browser I have on whatever machine, while some server maintains the persistent connection to the Hotline server for me. Like an IRC bouncer, but for Hotline.
