Optimised for: programmatic browser session persistence
Anti-fit: not for end-users; developer infrastructure only
Pros & cons
Pros
Most developer-friendly path to remote browser agents — memory is structured around session replays, not chat history.
Cons
Infrastructure-tier product; not useful directly to end users without an agent layer on top.
Claims & capabilities
$40M Series B (June 2025) at $300M valuation. $67.5M total. 50M+ sessions in 2025. 1,000+ paying customers.

The Browser Company's AI-native browser; Atlassian acquired The Browser Company for $610M cash (announced 2025-09, closed 2025-10-21). Stores summaries and preferences locally; opt-in @history feature references up to 7 days of browsing as context. History/chats/bookmarks encrypted local-first.
- Fellou T1
Silicon Valley. Spatial agentic browser with explicit Agentic Memory layer learning from history and notes for instant recall of past research sessions. Operates on logged-in accounts (Quora, X, etc.); runs tasks while user is idle.
- Microsoft Edge Copilot Mode + Journeys (now Copilot in Edge) T1
Copilot Mode retired 2026-05-13; its features now ship as Copilot in Edge. Journeys clusters browsing history into topic cards on the new tab page (desktop, and US mobile); Copilot long-term memory can reference past chats and browsing history with user controls; agentic 'Browse with Copilot' (formerly Copilot Actions) for US Microsoft 365 Premium.
- Opera AI (formerly Aria) T2
Memory feature stores user-declared preferences and facts; injected into future prompts. Understands current tab content; manages open tabs contextually. Memory off by default, end-user controlled, stored alongside the prompt rather than the LLM.
