Move your team from Microsoft Copilot to Perplexity.
Each person gets a short interview, then a personalized step-by-step guide showing exactly where their saved work, prompts, and projects land in Perplexity — and the few things that need a manual step, walked through. You send one invite; nobody becomes the help desk, and nothing in Microsoft Copilot is changed or cancelled. Want to see where you’re paying for both first? Run the free audit.
Copilot custom engine agents (hosted on Azure) can autonomously execute multi-step workflows, call external APIs, write to CRM/SharePoint, and post proactive messages in Teams; Perplexity Comet is a Chromium-based AI browser whose assistant takes actions on web pages (navigating, filling forms, adding items to cart, reading/writing Gmail and Google Calendar). To shift web-based autonomous tasks from Copilot to Perplexity: install Comet (Mac/Windows/iOS/Android), describe the goal in plain language in the side panel, and authorize Gmail/Google Calendar connectors if the task involves email or calendar actions — Comet will navigate and act on pages directly. To shift back to Copilot: redeploy tasks as declarative agents via M365 Agent Builder with the relevant API actions, or use custom engine agents for tasks requiring Azure-hosted orchestration and Teams integration. Comet is best for web-browsing automation; Copilot agents are best for M365-integrated workflows.
- Warning: Comet's free-tier agent runs in the browser with the user present; the Max plan's background assistant runs multi-task jobs in parallel without the user watching, which is the closer equivalent to Copilot's proactive messaging agents.
- Warning: Copilot custom engine agents require Azure hosting and engineering effort to build; Comet requires only a natural-language goal in the side panel, making the bar to automation dramatically lower on the Perplexity side.
- Warning: Perplexity Computer (credit-metered, separate from Comet's free in-browser mode) handles longer-running agentic tasks; Max users receive 10,000 monthly credits, but credit consumption per task is not published, making cost unpredictable for heavy users.
Both products offer a conversational AI chat interface with web-grounded responses. Copilot Chat is accessed at Microsoft365.com, the M365 Copilot app, or Teams; Perplexity is accessed at perplexity.ai or its mobile apps. To shift daily research and Q&A tasks from Copilot to Perplexity: start using Perplexity's default Search for quick questions and Pro Search for multi-step queries; Deep Research produces structured long-form reports comparable to Copilot's summarization of M365 content. To shift back from Perplexity to Copilot: sign in at Microsoft365.com and use Copilot Chat (web) for general queries, or upgrade to the M365 Copilot add-on to ground responses in your organization's emails, files, and calendar events. Note that Perplexity always pulls live web sources and shows citations; Copilot Chat (without the add-on) also uses web search, but the add-on version grounds responses in your private M365 data instead.
- Warning: Copilot Chat grounded in M365 data (emails, SharePoint, calendar) requires the Microsoft 365 Copilot paid add-on; the free-tier Copilot Chat in M365 uses only web search, making it functionally closer to Perplexity's free tier.
- Warning: Perplexity always shows numbered citations for web sources; Copilot does not consistently surface citations in its UI, which matters for users who need source verification.
- Warning: Deep Research (the Perplexity equivalent of a long-running research task) is capped at approximately 20 queries per day on Pro; there is no direct equivalent cap in Copilot, but usage is metered per the M365 Copilot license seat.
Copilot supports declarative agents (built with Agent Builder or the M365 Agents Toolkit) that run on Copilot's orchestrator with scoped instructions, actions, and data connectors; Perplexity's nearest equivalent is a Space configured with Custom Instructions, attached files, and a chosen model, which acts as a reusable persona. To migrate a custom Copilot agent to Perplexity: copy the system prompt/instructions from the agent definition into a Space's Custom Instructions field, upload the relevant knowledge files to the Space, set the preferred model, and share the Space URL with teammates. To shift back from Perplexity to Copilot: export the Space's custom instructions and file list, recreate them as a declarative agent in M365 Agent Builder, and deploy to Teams or Outlook. There is no automated export path between the two platforms — migration is a manual copy-and-recreate process.
- Warning: Copilot declarative agents can call external APIs and trigger Power Platform flows; Perplexity Spaces have no equivalent action/API-calling capability — they are purely retrieval + generation assistants.
- Warning: Copilot agents deploy to Teams, Outlook, Word, Excel, and PowerPoint as first-class surfaces; Perplexity Spaces are accessed via the Perplexity web app or a shared URL with no native integration into Microsoft 365 apps.
- Warning: There is no public marketplace for Perplexity Spaces as there is for Microsoft 365 agents; sharing a Space shares the URL but not an installable package, limiting discoverability within an org.
Copilot automatically grounds every prompt in the user's Microsoft 365 data (emails, OneDrive/SharePoint files, calendar, Teams messages) via Microsoft Graph — no manual configuration needed. Perplexity grounds responses in connected external services via its Connectors feature (Gmail, Google Calendar, Outlook, Notion, GitHub, Linear, Google Drive, OneDrive, SharePoint, Dropbox, Box). To shift an org-data-grounded workflow from Copilot to Perplexity: enable the relevant connectors at perplexity.ai/account/connectors (or perplexity.ai/enterprise/app-connectors for Enterprise), authorize each service, then reference connected data in queries (e.g. 'Summarize my unread Gmail threads about Project X'). To return to Copilot: remove Perplexity connector tokens in its account settings; Copilot's Graph grounding re-activates automatically when the M365 Copilot add-on is active. Overlap note: both products can connect to OneDrive/SharePoint and Outlook, so files and email context can be sourced from the same underlying store on either platform.
- Warning: Copilot's Graph grounding is automatic and covers all M365 data the user has permission to access; Perplexity connectors must be individually authorized and only read the specific services enabled — there is no automatic, comprehensive organizational data sweep.
- Warning: Perplexity's file-store connectors (Google Drive, SharePoint, OneDrive, Dropbox, Box) are gated to Enterprise Pro and Max plans; Pro users only get the core productivity connectors (Gmail, Google Calendar, Notion, GitHub).
- Warning: Copilot uses the Microsoft Graph Semantic Index for conceptual retrieval; Perplexity connectors use real-time retrieval without an equivalent semantic index layer, so deep cross-document concept matching may be weaker.
Copilot embeds document AI inside Word, Excel, and PowerPoint (drafting, rewriting, summarizing, formula generation); Perplexity lets users attach files to any thread or a persistent Space and ask questions against the content. To migrate a document-review or summarization workflow from Copilot to Perplexity: upload the PDF, DOCX, XLSX, or PPTX to a Perplexity thread (up to 10 files, 40 MB each on Pro) or pin files to a Space for repeated use, then prompt for summaries, comparisons, or extracted data. To shift back from Perplexity to Copilot: open the file directly in Word, Excel, or PowerPoint and use the Copilot pane (ribbon) for inline drafting, rewriting, and chart generation. Thread uploads in Perplexity auto-delete after 7 days; move recurring files to a Space to persist them.
- Warning: Copilot's document AI is tightly integrated with the Office editing surface — it can rewrite, transform, and generate new content inside the document; Perplexity can only read and analyze attached files, not write back to them.
- Warning: Perplexity Pro file uploads are rate-limited (approximately 10 per day as of 2026, though the exact cap is unpublished); high-volume document review workflows may hit this ceiling.
- Warning: Thread-uploaded files in Perplexity expire after 7 days; for persistent document knowledge bases, files must be explicitly added to a Space, and Space file limits vary by plan (50 files on Pro, 500 on Enterprise Pro).
Copilot Chat sessions live within Microsoft 365 surfaces (Teams, M365.com, Outlook) and conversations are tied to the Microsoft 365 user account and accessible from any M365 surface; Perplexity organizes threads and files into Spaces — named, topic-scoped workspaces with custom instructions, model preferences, and file repositories. To shift project-based knowledge work from Copilot to Perplexity: create a Space for each active project, set Custom Instructions to define the context (e.g. 'You are assisting with the Acme contract renewal'), upload relevant documents, and invite teammates as contributors. Pin threads from research sessions to keep all work grouped. To move back: export Perplexity threads (PDF or Markdown) to OneDrive/SharePoint for reference, then continue work in Copilot Chat or the M365 apps where your files already live.
- Warning: Perplexity Spaces have a file cap that varies sharply by plan (50 files on Pro, 500 on Enterprise Pro, 5,000 on Enterprise Max); teams with large document libraries will hit limits quickly unless on Enterprise.
- Warning: Copilot Chat history is siloed to the Microsoft 365 account and not easily exported in bulk; there is no one-click export-all for Copilot conversations comparable to Perplexity's per-thread PDF/Markdown export.
- Warning: Perplexity Spaces support viewer and contributor roles but lack the granular permission model available in SharePoint/M365; sensitive organizational content should be shared with care on Perplexity.
