About
I’m Lev. Online I’m ThatLev.
I make anime-style characters that personify AI models such as Claude, ChatGPT, Gemini and Grok, sell them as chat stickers, wallpapers and profile pictures here on thatlev.com, and build Mac apps including ThatPet, UltraNotch, StillOn and Kelvin.
The characters
Each character stands for an AI model people talk to every day, with the model’s name and version on her shirt. The main cast:
- Opus 5.5 (Claude Opus, Anthropic)
- Fable 5.1 (Claude, Anthropic)
- Astra 6 (ChatGPT, OpenAI)
- Flash (Gemini 3.8 Flash, Google)
- Argon (Gemini family, Google)
- Grok 4.6 (Grok, xAI)
- User-chan (the person typing the prompts)
The full list, with what each one looks like, is in Meet the cast. They come as chat stickers, wallpapers and profile pictures in the shop.
These are unofficial characters by Lev. ThatLev is not affiliated with or endorsed by Anthropic, OpenAI, Google, xAI, Moonshot AI, Alibaba, Z.ai, DeepSeek or Mistral AI. Model names belong to their owners.
The apps
I also build software, mostly small Mac apps for people who work with AI agents. Each has its own website:
- ThatPet: A desktop pet for Mac that reacts to Claude Code, Codex, Cursor and OpenCode.
- UltraNotch: Music, calendar, AI usage limits, sales and views in the MacBook notch.
- StillOn: Keeps a MacBook working with the lid closed so AI agents and builds keep running.
- Kelvin: MacBook battery care: charge limit, heat protection and power per app.
Everything else I am building, including the betas and the ideas still on a waitlist, is on the projects page. I write about how they work in my notes.
