Perplexity adds Personal Computer macOS app to run autonomous agents: what changed

Perplexity has released Personal Computer, a new macOS application that embeds its Perplexity Computer architecture directly on users’ devices so persistent, agentic workflows can run locally on Macs and Mac mini. The company says the app is available for download to all users today and that the older Perplexity Mac client will be deprecated in the coming weeks—a shift that lets teams keep long-running automation and background processing on a personal device rather than exclusively in the cloud.

The product supports more than 400 connectors to third — party services and can pair with Perplexity’s Comet browser to operate web-based tools even when a direct connector is not available. That pairing enables agents to bridge local context and web workflows: agents can drive browser — based interfaces through Comet while still leveraging local files and applications for tasks that require on-device context. Perplexity lays out practical use cases for Personal Computer: compiling research briefs from folders of PDFs and open browser tabs; comparing documents and summarizing differences; assembling drafts from notes scattered across multiple native apps; and cross — referencing local CSVs against web sources. The system is positioned to produce live dashboards instead of static outputs and to route key decisions to humans while handling connective, repeatable work autonomously.

The company frames this release as the next step in an evolution from its original answer engine through the Comet web-agent work to a model — agnostic, agentic harness that orchestrates models, files, and tools. Perplexity describes the engineering effort as focused on reliable outcomes rather than one-off demos, moving core compute and orchestration closer to where users actually perform work to reduce friction for tasks that depend on local context and extended background processing. On distribution and billing, Perplexity notes the macOS app is available for direct download now but is not yet listed in the App Store. Computational credit usage for agent work is tied to Perplexity’s Pro and Max subscriptions where applicable. The company recommends users switch to the new app promptly because the legacy Mac client will be phased out soon.

For always‑on scenarios, Perplexity highlights the Mac mini as the best option: a central device can host teams of agents 24/7 while other Apple devices are used to initiate tasks or approve human‑in‑the‑loop steps. The combination of local execution, Comet — based web orchestration, and Perplexity’s sandboxed servers is presented as a way to keep long‑running jobs quiet in the background and surface results only when human attention is required.
