I love integrating into spreadsheets. Super easy to use. Reminds me a bit of mailmerge.

I don't have much experience with modern finetuning, but isn't it highly technical. How many layers do you want to change? What is the learning rate? Does that need to be visible to the user? How many examples are needed in practice

Finetuning is technical, but OpenAI hides things like layers, learning rates, and uses LoRA under the hood. You just upload examples - usually around 50.

But even that’s too much for most business users. Choosing input/output fields, generating and validating JSONL still feels like coding. That’s why we built PromptRepo: it turns finetuning into a guided, no-code workflow using spreadsheets.
