Memory that compounds

Each Computer task is a scoped workflow delegated to subagents across 19 models. The next task starts fresh, without inherited context.

Vellum builds a structured, persistent memory of your work, people, and patterns automatically. Every conversation makes the next one sharper, and that memory follows you across every surface.

Data privacy

Computer is fully cloud-hosted by Perplexity. Data is processed across the 19 orchestrated models under Perplexity's data and provider policies.

Vellum is available as both Vellum Cloud and a native Mac app on your own machine, and Vellum never has access to your data on either path. Credentials live in an isolated vault the model never sees, so prompt injection cannot exfiltrate keys.

Frequently asked questions

When should I choose Vellum over Perplexity Computer?

Choose Vellum if you want a persistent personal AI assistant that builds memory of your work and people over time, runs proactively in the background, and shows up across native Mac app, iOS, web app, voice, email, Telegram, and Slack with one shared memory. Vellum runs on a Free Base plan with Pro from $50/mo, while Perplexity Computer requires a Perplexity Pro plan at $20/mo or Max at $200/mo.

When does Perplexity Computer make more sense than Vellum?

Perplexity Computer is Perplexity's cloud-based agent orchestrator that coordinates 19 different AI models to run multi-step workflows in the background. If you already pay for Perplexity Pro or Max and primarily want to delegate research-heavy, multi-model workflows like competitive intelligence reports or end-to-end content production, Computer's orchestration pattern covers that workload well.

How much do Vellum and Perplexity Computer cost?

Perplexity Computer is included on Perplexity Pro at $20/mo and Perplexity Max at $200/mo, with Computer for Enterprise on Enterprise Max priced custom. Vellum offers a Free Base plan, plus Pro from $50/mo with pay-as-you-go credits, configurable compute and storage, and your assistant's own email and subdomain.

How does memory work in Vellum vs Perplexity Computer?

Vellum builds a structured, persistent memory of your work, people, and patterns automatically across every session, shared across native Mac app, iOS, web app, voice, email, Telegram, and Slack. Perplexity Computer operates per task: you describe an outcome, the orchestrator delegates to subagents across 19 models, and each task is scoped. There is no persistent personal memory layer that compounds across Computer tasks.

What integrations do Vellum and Perplexity Computer support?

Vellum connects to 50+ services through managed OAuth with one-click setup, including Google Workspace, Slack, Notion, GitHub, Linear, X, and Telegram. Perplexity Computer connects to 400+ apps via OAuth, including Gmail, Outlook, Slack, Notion, Salesforce, Snowflake, and Databricks. Vellum's set is curated for personal-assistant workflows across consumer and prosumer tools, so the connectors that ship are the ones that show up in daily use.

Does Perplexity Computer work on iPhone or only desktop?

Perplexity Computer is currently available through the Perplexity web app on desktop and through Slack. There is no native iOS or Mac app for Computer specifically. Vellum ships as a native Mac app, an iOS app, and a web app, with voice, email, Telegram, and Slack surfaces, all sharing the same memory.

Where does my data live with Vellum vs Perplexity Computer?

With Vellum, your data lives on Vellum Cloud with per-customer isolation, encryption at rest, configurable retention, and custom LLM credentials so model API keys stay under your control. Vellum never has access to your data on any deployment path, whether you run the native Mac app on your machine or use Vellum Cloud. With Perplexity Computer, data is processed in Perplexity's cloud across the 19 orchestrated models under Perplexity's data and provider policies.

Is Vellum or Perplexity Computer better for non-technical users?

Both target non-technical users. Vellum is built for every human, with a native Mac app, an iOS app, and a web app, plus voice, email, Telegram, and Slack, all syncing one persistent memory. Computer runs inside the Perplexity web app and Slack on paid Perplexity Pro or Max plans, where users describe research and execution workflows for the orchestrator to deliver. Vellum is the broader fit for ongoing personal AI that follows you across surfaces and remembers what you're working on.

Can I run Vellum or Perplexity Computer on my own machine?

Vellum runs as a native Mac app on your own machine, with iOS, web app, voice, email, Telegram, and Slack surfaces in sync. If you want continuous 24/7 background work without keeping your laptop open, Vellum Cloud handles it on the Pro plan from $50/mo with pay-as-you-go credits, configurable compute and storage, and your assistant's own email and subdomain. Perplexity Computer is cloud-only and runs entirely in Perplexity's infrastructure. There is no self-host option.

Can I use Vellum and Perplexity Computer at the same time?

Yes. They serve different jobs. Some people use Vellum as their always-on personal assistant across surfaces and use Computer when they want a high-budget multi-model research workflow delivered as a finished output. Most people consolidate on one over time once they see how Vellum's persistent memory and multi-surface presence cover the day-to-day.

What's the difference between Vellum's memory and Perplexity Computer's subagent workflows?

Vellum's memory is structured, persistent, and assistant-managed: it builds up an understanding of you across every conversation, surface, and action, and that memory is the same whether you reach the assistant from Mac, iOS, web app, voice, email, Telegram, or Slack. Computer's subagent workflow is task-scoped: you describe an outcome, the orchestrator decomposes it, subagents execute across 19 models, and the workflow ends. Future tasks start fresh, without inherited context.
