FineTuner trains your own AI on your content (PDF, YouTube videos, websites...) 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.
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!
Been waiting for something like this. Tried FineTuner today. Genuinely impressed. Took me 2 minutes to spin up a custom AI trained on my own PDFs.
Impressive! Fine-Tuner makes it incredibly easy to build custom AI chatbots without any coding.
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!
The promise of “PDFs → fine-tuned GPT in minutes” is huge for teams drowning in proprietary docs. 🙏
I’m already picturing a growth-ops use case: feed FineTuner our brand guidelines and PDF case studies, then deploy a chat assistant on our landing page that speaks in perfect “house voice.” Before I green-light it, a staging area where I can preview live answers, tweak prompts, and one-click promote to production would be invaluable—way cleaner than our current RAG workaround.
Any plans for pay-as-you-go credits so everyone can experiment without a full subscription?
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?
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!
