Haku

Haku offers a unique Mac control system for your computational agents, enabling interaction with native applications, Chrome, and Safari through a single MCP server. This system includes key features: • On-device element filtering for significant token reduction • Seamless control over native Mac applications and web browsers • Persistent learning through cached searches and task notes • Semantic code search across indexed repositories • Agent-driven demo and onboarding video creation Haku dramatically cuts down the "browsing bill" for your agents by filtering down web pages and applications to only the essential elements. This on-device processing takes milliseconds, transforming a typical Chrome action from consuming 50,000 tokens to under 7,500. This efficiency compounds over time, as Haku caches web searches and document lookups, ensuring that subsequent runs are cheaper and start with prior context. Agents can also leave notes on completed tasks, further reducing re-discovery costs for similar future assignments. The platform provides robust native Mac automation, allowing agents to drive applications like Mail, Calendar, Notes, Reminders, and Messages, as well as web browsers such as Chrome and Safari. It integrates with popular tools like Slack, Notion, Linear, and Figma, making complex, multi-application tasks seamless. For developers, Haku includes semantic code search, indexing repositories once and allowing agents to search by intent rather than tedious manual scanning. Built for developers and teams using computational agents with Claude Code, Cursor, OpenClaw, or any MCP client, Haku ensures fully local operation. It's ideal for those focused on optimizing resource usage and enhancing the capability of their agents, allowing them to create dynamic demos and onboarding videos without extensive human intervention.
