Multi-model AI sidebar and Gmail extension — one subscription across several model families

nily.aiAbout Nily AI
Nily AI is a multi-model assistant delivered mainly as a browser extension and sidebar, so it works on top of whatever page you are already on instead of asking you to move into a chat app. One subscription reaches several model families — the vendor lists ChatGPT, Gemini Pro, Perplexity, Bing Copilot and Mistral — which makes model comparison a normal action rather than a separate set of accounts. The surface is broad. There is a Gmail extension that composes and replies in over forty languages with tone control, scheduling links, auto-draft and a knowledge base. There is a sidebar copilot that chats with the current webpage, with PDFs, with YouTube videos and with images, plus web access and a code interpreter. There is a LinkedIn toolset with a post generator and a carousel generator. There is a summarisation layer for videos, documents, blogs and articles, with flashcard generation for study. A writing toolkit adds a document editor, image generation, a capture-and-ask vision mode and custom prompt engineering, and a coding set covers code explanation, HTML preview and Mermaid diagrams. The vendor reports over 300,000 users and publishes third-party ratings — 4.5 on G2, 3.9 on Trustpilot, 4.9 on the Chrome Store and 4.0 on Capterra — which is more transparency than most tools in this bracket offer.
