Pros & cons
Fellou
Pros: Agentic browser with first-class memory of past task trajectories, not just URLs visited.
Cons: New entrant with limited track record; sustainability depends on funding traction.
Microsoft Edge Copilot Mode + Journeys
Pros: Journeys timeline memory — cross-tab, cross-session reconstruction of research arcs — is more sophisticated than competitor history features.
Cons: Edge browser lock-in; Microsoft account required to retain Journeys across devices.
