Real, useful tools I have built and use myself. This is what the skills I teach actually produce.
A few show what is possible: finance, memory, a full app, a team of agents at work. One of them you can build yourself right now, free.
Each one solves an actual problem.
A live stock dashboard that runs on your own machine: real-time prices, charts and per-company fundamentals for the names you follow. The view a desk analyst keeps open all day.
For anyone who follows the markets. Runs locally, no data leaves your computer.
A private folder of plain files your AI reads at the start of every session, so it remembers your projects, your decisions and your context. The folder is the brain; Obsidian is one way of looking at it.
For anyone tired of re-explaining their work to AI every single time.
A full voice app I built from scratch: you speak, it teaches you Spanish in real time, corrects you as you go, and tracks what you have learned across sessions.
For proof that this ships real, working software, not just clever prompts.
A live dashboard that watches a whole team of AI agents work one job at once, their checks landing in real time.
For anyone who wants to see what serious AI delegation actually looks like.
No account, no cost, no GitHub. Copy the prompt, paste it to Claude, and watch it build a real tool in one go.
A clean drag-and-drop task board (To do / Doing / Done) that lives in a single file on your computer and works forever, offline, with nothing to sign up for. Proof that useful does not have to mean complicated.
Paste it to Claude (in the VS Code extension, which needs a paid plan, or the app). It builds the whole thing from scratch and remembers your tasks in your browser. The safest one to start with.
Small parts, not full builds: plain-text files that give your AI a head start. Download one, drop it in your project folder, edit the bits in brackets.
Tells the AI who you are and how to work in a project. Drop it at the top of a folder and the AI reads it automatically.Reach for it when you keep repeating the same context every chat.
A simple brief for handing a task to your AI: goal, context, what done looks like, how to check it.Reach for it when a task is big enough that explaining as you go makes a mess.
A reusable instruction the AI can run again and again. Rename it, edit the steps, save it in your skills folder.Reach for it when you type out the same multi-step request more than once.
A one-page README plus a folder layout for a notes vault your AI can read as shared memory.Reach for it when you want your AI to remember your work across sessions.
The shelf keeps growing. A few I am lining up:
I also share the thinking and building skills I lean on every day: deep-thinking, red-team, PRD, build. Paste one into any chat and it works. Free AI Skills → Or browse the whole resource library →
I teach this one to one and build with teams. Book a free chat, tell me what you are trying to do, and we get a real tool working on your actual work. Prefer to say hello first? Connect on LinkedIn.
