Easy Ollama Modelfile editor

🦙 Easy Ollama Modelfile Editor

Take the hassle out of editing Ollama model files.
This tool lets you open, edit, and duplicate modelfiles for any Ollama-based model directly from your PC — no more typing long command-line strings just to tweak parameters.

With simple drop-down menus, editable text fields, and a built-in System Key Reference, it makes modifying models fast and beginner-friendly. Perfect for customizing existing models with new personalities, system prompts, or behavior adjustments.

⚙️ What It Does:
• Edit and save modelfiles for any Ollama-compatible model
• Quickly duplicate and customize models (e.g., edit Gemma3 modelfile and save as a new variant)
• View and tweak system parameters with a handy reference guide

🚫 What It Does Not Do:
This tool is for editing and generating model variations, not for training or creating entirely new LLMs from scratch.

I built this for my own projects to experiment with different model “personalities” and prompt structures — and now it’s available for anyone who wants the same convenience.

Note: Your original model remains untouched; the editor creates a new, separate version when you save changes.
