Perplexity Comet

Incomplete, delayed and not restorable: 'Export my data' delivers a ZIP of threads by email without instructions, connectors or logic, and Perplexity documents no import.

• GDPR Compliance at Perplexity

Threads come through the account export and browsing data sits in the local profile, but assistant instructions, model routing, connector credentials and executable logic stay with Perplexity, as does anything that identifies the agent.

• Local Data & Device Storage
• GDPR Compliance at Perplexity

The browser runs locally, but the Comet Assistant's inference and agent logic run on Perplexity's servers. No exportable agent runs on an open-source runtime.

• Comet Data Privacy & Security FAQs

Assistant identity is the Perplexity account, and nothing lets others verify it is the same agent without Perplexity.

• Comet Terms of Service

The Assistant needs a Perplexity account and servers, and features are gated by plan, so the provider can disable or degrade it.

• Comet Terms of Service

Memory, connectors, background assistants and agentic browsing are Perplexity-hosted services that do not survive a move to another model provider.

• Comet memory
• Comet now available for everyone, background assistants

Local browsing data uses Chromium's on-device storage (largely SQLite and JSON), which ordinary tools can read. Assistant memory and threads sit in Perplexity's cloud in undocumented formats.

• Local Data & Device Storage
• What is Comet's Browser Engine?

Perplexity does not show owners the Comet Assistant's system prompt or the tool instructions it adds to the model context.

• The New Comet Assistant

Queries sent to the Assistant are processed and kept by Perplexity, crash reports and IP data are collected, and consumer data is kept for model improvement by default. Provider-held data therefore exists outside owner-inspectable state.

• Perplexity Privacy Notice
• Data Collection at Perplexity

The Assistant sidecar shows its reasoning and steps as it works, and threads persist in the account, but no complete record of every action and tool call is documented as available to the owner or leaving with the export.

• Comet Assistant puts you in control

The Assistant's executable logic is proprietary and server-side. Owners can save prompts and shortcuts but cannot read the agent logic.

• Comet Terms of Service

Perplexity says it does not send prompts or conversation content to advertisers, and it confirmed in 2026 that it is winding down its ads programme (sponsored follow-up questions). Owners cannot see or switch off how merchant and publisher partnerships affect ranking, and web-page content can inject instructions, as Brave's prompt-injection research showed.

• Agentic Browser Security: Indirect Prompt Injection in Perplexity Comet

No durable record of every consequential Assistant action is documented, nor that an action which cannot be recorded does not proceed.

• Comet Assistant puts you in control

Threads and local history can be deleted without a trace, and no other way to detect changes to an action record is documented.

• Self-Serve Data Deletion

Perplexity does not document whether the Assistant, which operates the browser, can alter or delete records of its own actions such as threads or history.

• Comet Data Privacy & Security FAQs

There is no audit trail of Assistant actions. Only threads, through the account export, and local browser history can be read.

• GDPR Compliance at Perplexity

No record of the Assistant's exchanges with other agents or services is documented that could be matched against a counterpart's record.

• The New Comet Assistant

Comet is built on open-source Chromium, but Comet and its Assistant are proprietary and have no published reproducible builds.

• What is Comet's Browser Engine?
• Comet Terms of Service

Owners can see their settings but not the effective server-side configuration, such as system prompt, routing and model versions.

• What advanced AI models are included in my subscription?

The Assistant acts through the owner's web sessions and Perplexity-held connector grants; recipients have no way to verify a message came from this agent under the owner's authority.

• Managing Comet Assistant permissions

No action record with checkable integrity exists, so nothing can be verified with open tools.

• Comet Data Privacy & Security FAQs

Agent state is split between the local profile and Perplexity's cloud, where memory and configuration are not fully exposed, so the owner cannot verify whether the whole state changed.

• Comet memory

Owners can set personalization preferences and memories that shape responses. They cannot read or rewrite the Assistant's system instructions.

• Comet memory

Saved memories can be viewed, searched, filtered, deleted or turned off in Settings. Content-level editing and provider-side derived data are not fully exposed.

• Comet memory
• Introducing AI assistants with memory

Owners can create reusable prompts or shortcuts, and custom skills in the separate Perplexity Computer product. The Assistant's executable logic cannot be changed.

• Custom Skills, Model Council, and Voice Mode in Computer

Owners can allow or prohibit history access, navigation and site interaction, and can block specific sites. Pro, Max and Enterprise users can add custom remote MCP connectors.

• Control what Comet Assistant can use
• Computer for Pro subscribers, Computer for Slack

Paid plans can pick among Perplexity-hosted models, for example Claude Sonnet or Opus for the agent. Local or open-weight models are not supported, and Free users cannot choose.

• What advanced AI models are included in my subscription?

Model selection, custom connectors and parallel background assistants are limited to paid tiers.

• What advanced AI models are included in my subscription?
• Comet now available for everyone, background assistants

Owners can block sites and disallow site interactions for the Assistant, and connector access needs approval. There is no documented control over recipients or channels, and whether site blocks are enforced outside the model has not been independently verified.

• Control what Comet Assistant can use

Owners can have the Assistant ask before acting, per task or always. It pauses before logins and purchases, but the sensitive-action pause depends partly on the Assistant recognizing the action, and an 'Always Allow' mode removes confirmations.

• Managing Comet Assistant permissions
• Comet Assistant puts you in control

The Assistant has a Stop button, and Perplexity documents that users can stop the agent at any time or pause its access.

• Comet Assistant puts you in control
• Control what Comet Assistant can use

Browsing data stays local by default, but crash reports and IP data are sent even in Incognito. 'AI Data Retention' for model improvement is enabled by default on Free, Pro and Max, which is opt-out rather than opt-in.

• Comet Data Privacy & Security FAQs
• Data Collection at Perplexity

Passwords and payment methods stay in the local browser, and Perplexity says the Assistant does not access them. Connector grants such as Gmail are held by Perplexity, can be revoked, and do not travel with the owner.

Account deletion is self-serve, and Comet's help center describes permanent erasure after 30 days. The July 2026 privacy notice replaced its 30-day commitment with retention 'as long as reasonably necessary'.
