Genspark.ai unveiled what it calls the world’s first web browser to run more than 150 generative artificial-intelligence models entirely on a personal computer, eliminating the need for cloud processing, company officials said.
The free Windows and Mac application, dubbed the GenSpark AI Browser, processes popular open-weight models such as GPT, DeepSeek and Gemma on device, allowing users to generate text, analyze pages and summarize video even when offline, the San Francisco startup said in a blog post . Company videos released this week show the software embedding an AI “super agent” into every site, capable of scraping data, comparing products and downloading research papers automatically .
Privacy is a key selling point. Because calculations happen locally, “user data never leaves the machine,” GenSpark said . The browser also ships with ad blocking, one-click migration from Chrome or Edge and an “autopilot” mode that can open tabs and compile research without human clicks .
The launch caps a rapid pivot for GenSpark, which shifted from an AI search engine to agent-based tools in April and reported $36 million in annual recurring revenue after 45 days, according to a June investor update . The 20-person firm has since rolled out an AI designer for brand assets and a mobile “super agent” app on Google Play .
Tech blog TestingCatalog, which first reported the browser’s release, called the product “a big step toward privacy-centric AI for everyday users” .
GenSpark did not disclose how it will fund the heavy on-device inference workloads, but said future revenue will come from a marketplace for premium models and plug-ins.
