Rane

Rane positions itself as a custom AI assistant layer for the browser. Rather than a single general-purpose chatbot, it focuses on assistants you configure yourself: you decide what data each one should learn, connect sources such as websites, PDFs and Notion pages, and let the assistant build long-term memory around that material. The result is a tailored co-pilot that answers in the context of your own knowledge rather than generic training data.

Distribution happens through the Chrome Web Store, where the extension is published by the owner of rane.ai. Once installed, assistants can be invoked on any website, so research, drafting and question-answering happen inside the tabs you already work in instead of a separate app. For teams, Rane supports sharing assistants with the whole organisation or with selected coworkers, and switching between specialised assistants is designed to be a single click.

Security and privacy are explicit selling points. Rane states that its custom assistants integrate with your data and tools securely, and it advertises SOC 2 Type II, ISO 27001 and ISO 27701 certifications along with a privacy-by-design approach. Because the product is sold through direct contact rather than a published self-serve price, teams evaluating it should expect a sales conversation before rollout. Note that the Chrome listing's published extension version dates from late 2023, so verify current capabilities and pricing directly with the vendor.
