Hark vs Genspark: which one should you use?
Genspark packs a lot into its AI browser: an Autopilot Mode, a super agent, on-device models and a store of tools. Hark does three things in Chrome and tries to do them calmly.
Choose Genspark if you want a feature-rich AI browser with autonomous browsing, local models and hundreds of connected tools. Choose Hark if you want a light agent inside Chrome for email, forms and bookings, with an approval before final steps.

Platform vs tool
Genspark is building a platform: a browser, a super agent, an MCP store with hundreds of tools, and models that run on your own machine. That breadth is its appeal. Hark is intentionally a tool: one side panel, three modes, a handful of actions. If you want to explore what agents can do, Genspark gives you more to explore. If you want your Tuesday errands done, less surface is an advantage.
Local models vs a simple privacy promise
Genspark’s on-device mode keeps some work entirely on your computer. Hark does not run models locally; instead it limits what leaves your browser — only what you choose to send, only when you ask — and does not store your conversations on its servers.
