Anthropic's non-technical desktop agent built on the Claude Code harness (no terminal required) that works over local folders, browsers (Claude in Chrome), and full computer use, with MCP connectors, Agent Skills, and plugins — expanded to web and mobile in July 2026 with cloud-run sessions for Max subscribers.
Credit-based all-in-one 'AI employee' workspace whose Super Agent mixes multiple frontier models with 80+ tools to produce slides, sheets, sites, and calls, and whose 2026 'Genspark Claw' gives each user a persistent cloud computer commandable from WhatsApp/Telegram/Slack/Teams.
Perplexity's Chromium-based agentic browser (free on all four platforms since April 2026) whose sidebar assistant reads pages and tabs and executes web tasks in the user's own browser, extended by 'Personal Computer' on Mac to local file editing, local computer use, and voice orchestration.
