Small, sharp AI skills for Claude and ChatGPT.
Each skill does one thing remarkably well — designed for a specific niche, sold for impulse-buy money, installed in a single command. No bloat, no subscription required.
What's a Skill Tree skill, exactly?
Not a chatbot. Not another AI subscription. Each skill is a small, permanent tool you install once into your AI — and it just knows how to do that one specific job from then on.
A focused, packaged tool
A skill is a small file pack — instructions, templates, domain references, refusal rules — that teaches your AI how to do one specific job remarkably well. Designed for a specific niche, not a general assistant.
Lives inside your AI
Install once and your Claude Code or ChatGPT gains the ability. Just describe your task in plain English — the skill activates automatically and produces a polished result.
Yours forever
Buy once, use as many times as you want, on as many of your devices as you want. No per-use fees, no subscription required — unless you want the all-access plan for the whole catalog.

Things people ask before buying.
What exactly am I buying?+
A small AI tool — a SKILL.md file plus bundled references — that you install into Claude Code or set up as a ChatGPT Custom GPT. It's permanent. You buy it once and use it every time you need that specific job done.
Do I need to know how to code?+
No. The install is a single command you paste into your terminal. After that, you talk to Claude or ChatGPT in plain English — the skill activates automatically when you describe what you need.
What if I don't use Claude Code?+
Every skill ships with both a Claude package AND a ChatGPT Custom GPT package. The ChatGPT version is a 2-minute setup (paste instructions + upload knowledge files) and works the same way.
Can I just write the prompt myself?+
You could. Most people don't — partly because the bundled references (templates, examples, domain checklists) are the real value, and partly because once it's a skill, you stop having to think about the prompt at all.
What if the skill doesn't work for my specific case?+
Email support@skilltree (link in footer) and we'll either fix the skill, refund the purchase, or both. Skills are versioned — when we ship updates, you get them.
Why subscribe instead of buying skills one at a time?+
If you'd install 3 or more skills in a year, the $19/mo plan saves you money — and the catalog keeps growing. New skills auto-unlock as we ship them.
