Designed for the web

The page you are reading and Nella, side by side.

  • Chat in the side panel

    One click on the Nella button, or Alt+Shift+N: Nella opens next to the page, without switching tabs.

  • Summarize this page

    The key points of the open article in one click, or a question about the page: “What does the author conclude?”.

  • Any selected text

    Right-click, Nella: explain, translate, rephrase, or fix spelling and grammar.

  • Nothing is read unless you ask

    The page text is only taken when you ask for it; form fields and passwords, never.

The same everywhere

Everything Nella does, here too.

The same account, the same conversations and the same plan on all your devices: what you start on one continues on the other.

  • Chat and write

    Emails, letters, summaries, outlines: describe what you need and Nella writes it in your language.

  • Build websites and apps

    Nella writes the code and shows the result live, in an isolated frame. Included in every plan, starting with a Free account.

  • Web search with sources

    For news and recent facts, Nella searches the web and cites its sources.

  • Files and photos

    Attach a document or a photo: Nella reads it, summarizes it or answers your questions about it.

  • Memory

    Your name, your work, your preferences: Nella remembers them from one conversation to the next.

  • Projects

    Group the conversations about one topic so you can pick up each piece of work where you left it.

  • Dictation and read aloud

    Speak instead of typing, and have answers read aloud.

  • Six languages

    English, French, Spanish, Portuguese, German and Arabic, with a right-to-left layout in Arabic.

  • Guest mode, no account
  • One account on all your devices
  • No ads
  • Mandatory security updates
