Hi Product Hunt! 👋

I built Nevatal because I kept pasting the same "act as a proofreader / translator / summarizer" prompts into a blank chat box. Nevatal gives each job its own focused form instead.

What's inside:

• 17 tools — Prompt, Explainer, Writer, Rewriter, Proofreader, Summarizer, Copywriting, Email Builder, Social Caption, Idea Generator, Translator, Sentiment Analysis, Document AI (chat with a PDF), Image Generation, Data Analysis (CSV → insights and charts), Data Formatter and Batch Runner

• Bring your own key — OpenAI, Google Gemini or OpenRouter. You pay your provider's rates; Nevatal adds nothing on top

• No account — your key is encrypted before it leaves the browser and held in an httpOnly cookie

• Free courses — six self-paced courses, 18 lessons, no key needed to read

• Self-hostable — MIT-licensed, two Docker images and a compose file

Document AI and Image Generation need a Gemini key; the other tools work with any of the three providers.

It's a personal, open-source project. Feedback on which tool to add next is very welcome!
