Voilà AI Assistant
Voilà AI Assistant
Voilà is a browser-extension assistant that opens on top of whatever page you are on, so you work in one window instead of switching to a separate AI site. It summarises the current page, article or YouTube video, rewrites, translates, shortens and fixes grammar in text you have selected in any input field, drafts and answers email inside Gmail, and — on the top tier — answers questions about uploaded documents, spreadsheets, PDFs and images. It also does web-grounded search with sources, generates images, and keeps a library of saved and pre-written prompts. Companion desktop apps for Windows and macOS plus mobile apps run on the same subscription. The value here is the shortcut, not the model underneath: it suits people who write inside other companies' interfaces all day, such as sales, support and recruiters.
