Similar systems

Other browser-agent memory in the catalog, ranked by inbound references.

  • Browserbase T1

    Cloud browser infrastructure for AI agents. Headless Chromium sessions with persistent cookies, localStorage, session recording — agent workflows carry state across runs. Memory at the session/automation tier rather than conversational.

  • Brave Leo T2

    Privacy-focused integrated assistant. Memory is user-curated: explicit facts and preferences persist across all sessions, stored locally with no server retention. Agentic browsing experiment (Brave Nightly Dec 2025) takes multi-step actions inside sites referencing those preferences.

  • Dia (Atlassian) T1

    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.

  • 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.

  • Perplexity Comet T1

    AI-native Chromium-based browser. Assistant operates across tabs and sessions; persistent memory of preferences; multi-step agentic tasks without leaving the browser. Memory is opt-in and server-side; enterprise memory tier separately available.
