FineTuner lets you train your own AI on your content (PDFs, websites, YouTube videos...) without writing a single line of code. Generate a high-quality dataset, fine-tune your model (GPT or Claude), and deploy it via API ready to use in minutes.

👋 Hey Product Hunt!
I’ve always dreamed of an AI that could absorb my own content and speak in my exact voice. Two months ago I finally asked Cursor:
“Can you write a script that automates fine-tuning GPT-4o on my own content?”
That innocent prompt kicked off an 8-week rabbit-hole:
100+ workflows tested, 16-hour days, $250 in OpenAI bills, countless Docker tantrums.
I’m a low-code guy, so I had to learn real backend stuff on the fly—async Python, routing, deployments, the lot. Every time the AI “almost” worked, dopamine kept me glued to the screen.
Yesterday the last bug finally gave in. The result is Finetuner:
⚡ What it does ⚡
Point it at your Docs, PDF, YouTube, websites — anything.
In minutes you get a fully fine-tuned GPT-4o (or Claude) that speaks exactly in your voice.
No YAML rituals, no JSON wrangling. Just upload, click, done.
🛠 Why it’s different 🛠
Built 100 % with Cursor. Yes, the same AI that writes the code now teaches your model.
Handles the whole pipeline: data scraping ➜ cleaning ➜ training ➜ validation ➜ ready-to-use API.
Works for clones (“Tweet like Steve Jobs”) or personal brands (your unique tone).

I’d love feedback from the PH community: features you’d want, edge-cases you’re worried about, or horror stories from your own fine-tuning adventures. Drop a comment or DM me. Happy to share the gritty details of building a “real” app entirely with AI.
Thanks for hunting, and may the (Force) fine-tunes be with you!

Impressive tool for simplifying AI model fine-tuning! The ability to use personal data sources like PDFs and YouTube videos without coding is a game-changer. Quick question: How does FineTuner handle data privacy and security, especially when dealing with sensitive information? Congrats on the launch!

@patpijanowski Thank you so much! 🙏 Really appreciate the support!
Great question.
When you upload content to Finetuner:
Your data stays private: we don’t store it beyond what’s strictly necessary for fine-tuning.
No data is used to train any global model everything stays isolated and tied to your fine-tuned instance.
We're also working on on-premise / self-hosted options for teams with stricter compliance needs.
That said, if you're handling very sensitive information, feel free to reach out happy to walk through how we’re approaching encryption, storage and access control.
Thanks again for the thoughtful question and the support!
Really like the idea and congratulations on the launch. Do you have any ideas on how much time it saves a company compared to training with code?

Really cool concept! Love that FineTuner lets you fine-tune models without code. As someone in the creative field, I’m curious - can I use this to build a personalized assistant that helps me generate better prompts for AI art or storytelling projects? Would love to explore that use case!
Impressive! Fine-Tuner makes it incredibly easy to build custom AI chatbots without any coding.
