Deepinder Goyal, founder of Zomato and vice chairman of Eternal, has unveiled Dark.ai, a new AI chatbot designed to keep users' conversations private. The service will use end-to-end encryption, which Goyal says will prevent even the company from reading users' chats.
Dark is expected to launch globally by the end of 2026.Goyal shared details about the upcoming service in Eternal's Q2 FY27 shareholder letter. He said Dark is being developed for people who want to use AI to discuss sensitive personal matters, explore confidential business ideas or conduct research without worrying about who might access their conversations.
The chatbot has already been used internally by Eternal's team for a few months. However, the company has yet to announce a firm public launch date.What is Dark.ai and how is it different from ChatGPT?Dark.ai is an AI chatbot, similar in its basic purpose to ChatGPT and Google's Gemini.
Users will be able to interact with AI, ask questions and explore ideas. Its main difference, according to Goyal, is its approach to privacy.https://t.co/EBCxtHEFZH – from the house of Eternal.
Coming soon. https://t.co/6j4ZJVJ5Ly— Deepinder Goyal (@deepigoyal) October 21, 2026AI services such as ChatGPT and Gemini offer privacy settings that let users manage how their conversations are used, including whether they can be used to improve AI models. However, turning off model training does not necessarily mean that conversations are never stored or accessed for other permitted purposes.
Dark aims to address this concern through end-to-end encryption. Goyal said the company would not be able to read users' conversations, even if it were forced to do so. "The uncertainty and the lack of trust we have with large AI companies limits the power of AI in our lives," Goyal wrote in the shareholder letter.He believes privacy concerns can prevent people from asking AI assistants sensitive questions about their health, finances and relationships.
Researchers and founders may also hesitate to share early-stage ideas if they fear that confidential information could become accessible to others.Dark.ai features Dark will run fine-tuned versions of advanced open-weight AI models on Eternal's own infrastructure. Open-weight models allow developers to adapt existing AI models rather than build everything from scratch.The platform's main features include End-to-end encryption.
The company basically says that the conversations will be encrypted to prevent the company from reading them, according to Goyal. Goyal's letter also talks about Encrypted memory, a memory management system controlled by users will allow the chatbot to retain context across sessions without giving the company access to their conversations.Eternal also says it is adapting advanced open-weight models to deliver high-quality answers.
Goyal said the models are being trained to prioritise what they believe is true rather than merely pleasing users. The company plans to publish benchmark results later.Dark is aimed particularly at founders, researchers, scientists, businesses and government organisations that handle sensitive information.
However, its privacy-focused approach could also appeal to ordinary users who want more confidentiality when discussing personal matters.When will Dark.ai launch?Eternal hopes to launch Dark globally by the end of 2026. The service is currently being tested internally, and details about its public availability, pricing and supported features are still awaited.- Ends
