Vibe coding (Andrej Karpathy) in Jupyter with Mito-AI - the Cursor for data scientists. My top 8 Tips

Published: February 25, 2025

Mito-AI: In the same league as Cursor, Flowise, Lovable, n8n - a powerful and well designed tool. A few weeks of vibe coding with Mito-AI in Jupyter, and I'm hooked.

Efficiency Boost

Smooth UI/UX and fast responses. No more copy-pasting code or tabbing through windows - used to break the flow. Cursor like experience. Still a Colab fan, but now defaulting to Mito-AI.

Vibe Coding - Andrej Karpathy on X. Excerpts:

"There's a new kind of coding I call 'vibe coding'… I barely touch the keyboard, just talk to Composer with SuperWhisper… I accept all suggestions… Copy-paste errors, usually that fixes it… I just see stuff, say stuff, run stuff, and it mostly works."

My top tips for using Mito-AI Copilot

1. Use vibe (voice) coding - Win + H (Cmd + H for Macs). If it's not working, go to Settings → Voice Activation Privacy → Turn on access.

2. One chunk at a time - avoid having it do too many things in one prompt. Much faster overall.

3. No need to copy-paste sample data - Mito-AI auto-detects dataframe schemas.

4. Refer to previous messages - has full conversation history. e.g: "You know you did that date extraction from that zip file name… do the same thing for this CSV."

5. Install with or without Mitosheet - pip install mito-ai mitosheet adds a nice visual spreadsheet view…but works without Mitosheet also. Try both. I like with Mitosheet.

6. Open Source / Pricing - Free tier (500 messages/month). Premium ($20/month) for unlimited completions + premium models + greater functionality. OR use the base version on an open-source basis with your API key - using this now. If usage increases, I'll move to premium.

7. Setting API key –

   • Session level (PowerShell): command: $env:OPENAI_API_KEY = "sk-proj…your-open-ai-key" … then start notebook from SAME terminal (command: jupyter-notebook)

8. Modeling - analysis - automation: validations critical - Need to ask the right questions, validate results, sometimes check the code. Best part - tools like Mito-AI & Cursor make this super-efficient too.
