Weightless AI

Free AI assistant in a floating window: fixes and rewrites your text in the page, summarises, translates. 8 engines, local AI.

Weightless AI puts an AI assistant in a floating window, opened with a shortcut (Alt+W, ⌥ Option+W on Mac) on any page, without leaving what you are doing. Free, no account to create, no middleman server. WRITE IN YOUR PAGES • Right-click in a text field (email, form, social network…) → “Weightless AI: rewrite”: fix, rephrase, shorten or change the tone. The text is replaced in place, in its original language, with an Undo button. • “Insert” button: the assistant’s answer is written right where your cursor is. READ AND UNDERSTAND • Summarise the open page, up to 100,000 characters with an online engine. • YouTube videos: on a video, Gemini watches it (picture and sound) and pulls out the key moments, each with a link to the right instant. • Compare 2 to 4 open tabs in a table: prices, features, strengths and weaknesses. • Right-click a selection → “Weightless AI: analyse”: summarise, translate, explain or reply to it by email. • Attached images and PDFs, built-in web search with clickable sources. • Translation into practically any language. TAKE ACTION • New “Actions” button under every answer: the AI spots appointments, tasks, reminders, addresses and contacts in the conversation and shows them as cards. • One click, and each item goes to the right place: the event opens already filled in in your calendar (or as an .ics file), the task in your task manager, the address in your maps service, the contact as a .vcf card. Several time slots suggested? A card prepares a date poll. • Reminders at the time you choose, shown as a Chrome notification, kept on your device. • Also by right-clicking a text: “Weightless AI: analyse › Find actions”. • Parcels: in a shipping email, the carrier and tracking number are found; one click opens the official tracking page, with a reminder on delivery day. • Nothing is saved without your click: the extension has no access to your accounts. THE ENGINE OF YOUR CHOICE Eight AI engines to choose from, one per tab. By default: Gemini, with a free key. You can also connect other online services with your own key, or use a local AI running on your computer: in that case, nothing leaves your device. READY IN TWO MINUTES If your computer runs Gemini Nano, the AI built into Chrome, the assistant works straight away, with no key at all. Otherwise, it guides you to create a free Gemini key in Google AI Studio, with no credit card, and paste it right into the window: it is checked instantly. MADE YOURS Preset personas to change the tone in one click, your standing instructions, your own “/” commands and favourite prompts, your colours, light or dark theme. Interface in 9 languages. EVERYWHERE An independent window that stays open when you switch tabs, up to 5 conversations side by side, Alt+W shortcut even on Chrome’s internal pages. Fully usable by keyboard, works with screen readers. Designed for Chromebooks, where it reopens at startup. Markdown or PDF export. YOUR DATA Weightless AI has no server: it collects nothing, contains no trackers and sells nothing. Your keys and conversations stay on your device. The content you submit is sent only to the AI provider you choose, solely to produce the answer; the list of providers is in the privacy policy. With a local AI, nothing leaves your device. With the free Gemini key, Google may use your requests to improve its products: for confidential text, prefer the local AI. The extension only reads a page when you ask it to, and only accesses all websites if you explicitly allow it. Optional sync through your own Google Drive, in a private folder reserved for the extension, which never accesses your other files. A rewrite that differs markedly from your text (a link, address or number that was not in it) is never put into the page automatically: you read it first.
