WOWLY- Your AI Agent Apr 02, 2026 1,300 Views

Perplexity’s Comet Assistant now remembers user preferences and past interactions, enabling smarter, context-aware responses and greater control over privacy and data. The upgrade marks a leap toward a personalized, transparent, and productive AI assistant.

Perplexity has rolled out a major upgrade to its Comet Assistant, embedding a built-in memory layer that remembers user preferences, interests, and past conversations. This enhancement transforms the assistant from a task-oriented chatbot into a context-aware, personalized AI companion, capable of evolving with each interaction and delivering smarter, more tailored responses over time.

Personalization Powered by Memory:

Comet Assistant now retains key details across conversations, making future answers more relevant and efficient. The memory layer synthesizes preferences automatically, so users no longer need to repeat context for ongoing projects or recurring tasks.
Memory works seamlessly across all available AI models, allowing users to switch between different reasoning engines without losing their accumulated context. This “context portability” ensures that your personal knowledge base grows alongside new features and models.
Users maintain full control over their data: memory can be switched off, individual memories can be managed or deleted, and privacy settings allow disabling data retention for model improvement.

Enhanced Productivity and Transparency:

The upgraded Comet Assistant can participate in complex, multi-step projects, such as trip planning, research, or shopping, remembering preferences like budget, dietary needs, or travel style for a more cohesive experience.
New transparency features let users see exactly what the assistant is doing in real time, with a sidecar panel revealing its reasoning and actions. This step-by-step visibility boosts trust and allows users to intervene or approve tasks at every stage.
Stronger safeguards ensure Comet pauses for high-risk actions—such as logging in or making purchases—and asks for explicit permission before proceeding, mirroring the judgment of a trusted human aide.

User-Centric Privacy and Control:

All user data and session histories are stored locally, with no telemetry sent to Perplexity’s servers, ensuring enterprise-grade privacy and compliance with major regulations.
Memory remains inactive in incognito mode, and users can choose privacy modes tailored to their comfort level, including strict, standard, and local-first options.
