Ask in Claude, ChatGPT or Gemini

No API key? You can still get AI help with your notes, using an AI app you already have.

Highlight a passage, or use the ask box under a lecture, and choose ↗ Ask in Claude / ChatGPT / Gemini.
Tentaku shows you exactly what it will copy — your question and the notes — and you can edit it. Nothing happens until you press Copy & open.
Tentaku puts that text on your clipboard and opens claude.ai, chatgpt.com or gemini.google.com in your browser.
Paste, read it over, and press send there yourself. Tentaku never sends anything and never reads the reply.

For Claude, you can tick an option to open the Claude app with just your question filled in (up to 1,000 characters); your notes stay on the clipboard, never in the link. Without the Claude app, claude.ai opens in your browser instead.

Whatever you send there goes to that service under your own account, and its terms and privacy settings apply — including whether it uses your chats for training. Tentaku never sends anything for you. Privacy

Still stuck? Email help@tentaku.app — include which tab you were on and what you pressed.
