Perplexity Computer Breaks Into Word, Excel, and Outlook

Perplexity Computer now runs as a native side panel in Word, Excel, PowerPoint, and Outlook for every paid Perplexity seat. Microsoft listed the add-ins on May 28, 2026, 24 days after Computer arrived in Teams, so the same storefront that hosts Copilot now also distributes a rival agent into those four apps.

The panel drafts in Word, writes into Excel models, builds decks, and composes Outlook mail from threads and attachments. It is a Marketplace install, not a Microsoft SKU, and it bills against a Perplexity plan.

Microsoft’s Store Now Hosts Copilot’s Rival

Copilot is still the assistant Microsoft sells inside those apps, grounded in tenant mail, files, and chats. Perplexity’s bet is different: available inside Microsoft Word, Excel, PowerPoint, and Outlook, Computer routes each job across 20+ models and pulls live web research plus connected files, then writes back into the open document.

That is why the listing matters more than the feature sheet. An IT admin can assign the add-in the same way they assign any other Office plugin, which means a second agent can sit on the canvas Microsoft reserved for its own product. Aravind Srinivas, Perplexity’s chief executive, put the claim in one line the day the add-ins went live.

The louder problem on the analyst side is not the sidebar chrome. It is an agent that writes into a real workbook whose named ranges, custom calendars, and DCF conventions were never designed for a multi-model passer-by. Copilot still has Graph grounding and a default place in the ribbon. Computer has to earn the same files through Marketplace, Entra, and a second invoice.

What Computer Does Inside Each App

Perplexity split the work by surface rather than shipping one generic chat box. Excel was already in a native side-panel beta when the Teams app launched on May 4, and the May 28 drop extended that pattern to the rest of the core Office set.

WHERE THE PANEL WRITES IN PLACE

The canned jobs Perplexity published are finance and legal work, not autocomplete. A three-statement model from a 10-K in SharePoint, a board deck whose charts come from named Excel ranges, and a negotiation draft that proposes tracked changes against a standard template are the examples on the launch note.

SAMPLE JOBS PERPLEXITY PUBLISHED

• Word redline: Prep a negotiation draft by comparing the latest mark-up with the standard template, proposing tracked edits, and building an issues list with fallback clauses.
• Excel model: Build a three-statement model from a 10-K pulled through SharePoint, with cited line items and a cross-workbook check against last quarter’s file.
• Renewal brief: Draft a customer brief in Word from a Salesforce record, two QBR decks in SharePoint, and the deal channel in Teams, with every claim cited.
• Board deck: Create a PowerPoint update from the finance workbook, charts taken from named ranges, each figure cited back to the source sheet.
• Call prep: Prep tomorrow’s negotiation in Outlook from the last six counsel threads, attached redlines, and a SharePoint playbook, with open issues attached.

SharePoint, OneDrive, Salesforce, FactSet, and Snowflake sit in that path, and Perplexity says Computer can also bring your own warehouse sources under existing access, retention, and audit rules. Citations are the company’s accuracy pitch: every answer and every figure is supposed to carry a source before anyone pastes it into a client file.

Three Marketplace Listings, One Sign-On

There is not one Office button. Perplexity published three Microsoft Marketplace products, and a single Perplexity sign-in then follows the user across the apps that got installed. Teams still takes an @mention of Computer in a chat or channel once that listing is in the tenant.

THE THREE LISTINGS TO INSTALL

• Word, Excel, PowerPoint: One Computer for Microsoft 365 product covers the three authoring apps from a side panel.
• Outlook: A separate Outlook add-in handles mail, briefs, and scheduling, and the listing says drafts and calendar invites need approval before anything is sent.
• Teams: The May 4 listing remains the chat and channel entry point, listed as Perplexity Computer in Microsoft Teams.

After you open the host app, you launch Computer from the sidebar, or you @mention it in Teams, and you sign in once. Office usage then follows the credit limits on the Perplexity plan, so an upgrade or downgrade changes how much panel time you have without a second product to relearn. The Marketplace pages also warn that an extra purchase may be required, because a Microsoft 365 seat does not include Perplexity.

Who Pays for the Extra Office Agent?

Computer in those apps is bundled into Perplexity’s paid tiers, not into Microsoft 365. Free Perplexity users do not get the panel. Shops that already buy Copilot keep paying Microsoft for that add-on if they want Graph-grounded Copilot in the same windows, then pay Perplexity again if they want Computer’s model routing and web-cited research on top.

PAID SEATS THAT UNLOCK THE ADD-INS

That stack is the mixed part of the launch. Perplexity gets distribution inside the apps people already have open. Microsoft still sells Copilot and still runs the store, the admin center, and Entra. The person who loses exclusive hold on the side panel is Copilot, and the person who pays twice is the tenant that wants both agents on the same workbook.

The 40 Percent Who Already Lived in Office

Perplexity’s own usage picture, not a third-party audit, is what it used to justify native add-ins. Before the plugins, people were already asking Computer for PowerPoint files and then pasting them by hand.

THE USAGE PICTURE PERPLEXITY CITED

• Microsoft-format output: Nearly 40% of Computer users had generated an output in Microsoft formats over the prior 30 days, then still had to copy it into PowerPoint and the rest.
• Labor-equivalent tally: Perplexity said Computer had performed more than $4.4B in labor-equivalent work by the May 28 launch, a company metric, not a revenue figure.
• Connectors: Teams can attach SharePoint and 400+ other files and apps so the panel is not limited to the open document.
• Executives: Perplexity said about 92% of C-levels on the product use Computer weekly, which is why the Outlook brief and Excel model examples read like staff work for a principal.

Killing that paste step is the product. A cited three-statement model that lands in the workbook you already have open is a different object from a chat transcript you retype into cells. It is also how Computer stops being a research tab and starts being another author of the file.

Entra, SSO, and the Review-Before-Send Rule

None of this installs itself across a tenant. Admins pull the plugins from Marketplace and assign them to users or groups in the Microsoft 365 admin center, the same flow they already use for other add-ins. Connector permissions and app registrations go through Microsoft Entra, so SharePoint, Outlook, and Teams access stays under IT, at least on paper.

Microsoft has been building its own shared memory for enterprise agents in the same tenant, which means a shop that already turned on Copilot can end up with two agent stacks reaching the same mail and files. Perplexity’s counter is controls, not a claim that the panel is Microsoft-native.

WHAT IT TAKES TO SWITCH THE PANEL ON

• Identity: Enterprise-grade access includes SAML SSO, audit logs, and admin controls that can enable Computer, pick allowed models, and manage connectors.
• Training: Perplexity says enterprise data is never used to train the underlying models and, on the product FAQ, remains within the tenant boundary by design.
• Human review: Users can review a change before Computer makes it; Outlook drafts and calendar invites stay parked until someone approves the send.
• Sensitive actions: The later Windows app, which talks to the same Office files, alerts before it sends mail or deletes a file, and it creates files in a sandbox with an audit trail.

That still leaves a trust decision the listing cannot close. Computer can read mailboxes, attachments, SharePoint libraries, and licensed data feeds, then write into the live file. Citation helps a reviewer check a number. It does not decide whether a second vendor should see the deal channel in Teams.

After May the Agent Left the Sidebar

The Office add-ins were the moment Computer stopped handing back a file you had to paste. The Microsoft push did not freeze on May 28. Perplexity kept adding surfaces that still touch Word, Excel, Outlook, and Teams, which is why a May plugin story still moves.

HOW COMPUTER ENTERED MICROSOFT APPS

1. May 4, 2026: Ships as a Teams Marketplace app for paid Perplexity seats, with @Computer in chats and channels, while the Excel side panel is still in beta. Perplexity cites Microsoft’s figure of more than 350 million Teams users.
2. May 28, 2026: Opens native add-ins in Word, Excel, PowerPoint, and Outlook, with one Perplexity sign-in across the installed apps.
3. July 28, 2026: Personal Computer for Windows starts on Windows 10 and 11 for Pro, Max, and Enterprise seats, so the same agent can create or edit local Word and Excel files on the PC. Perplexity by then put its labor-equivalent tally at more than $9.4B.
4. Late August 2026: Perplexity also lets people mail work to computer@perplexity.com, so Computer can read a thread and attachments and reply in that thread with Excel files, PDFs, and decks.

On August 25, Cameron Stow, who works go-to-market at Perplexity, still listed Microsoft 365 apps alongside Windows, Mac, iOS, Android, web, Slack, Teams, and Comet as places Computer runs. The May listings remain the in-app path: a Marketplace add-in, a side panel, and a tenant admin who has to want a second agent on Copilot’s desk.

Frequently Asked Questions

Which Perplexity Plans Include Computer in Microsoft 365?

Pro, Max, Enterprise Pro, and Enterprise Max all include the Office add-ins, and Computer credit use follows the same per-tier limits already on the account, so an upgrade or downgrade changes Office panel time without a new setup. Free Perplexity does not include the plugins, and a Microsoft 365 license alone is not enough.

How Do Microsoft 365 Admins Deploy the Add-Ins?

Admins install the plugins from Microsoft Marketplace and assign them to users or groups in the Microsoft 365 admin center. Connector administration, including permissions and app registrations, is handled through Microsoft Entra, and insight dashboards, audit-log configuration, data-retention controls, and SCIM are documented as opening only with 50 or more members or at least one Enterprise Max user in the organization.

Does Perplexity Train on Outlook Mail or Word Files?

Perplexity says enterprise data is never used to train the underlying language models, that actions are logged and auditable, and that this is meant to keep customer data owned by the customer. Enterprise Max is also listed with SOC 2 Type II, end-to-end encryption, and granular access controls on top of that no-training rule.

Is Perplexity Computer Available in Outlook on Mac?

Yes. Perplexity says Outlook is supported across web, the new and classic Outlook experiences, and Mac, which is why it claims most Microsoft 365 environments are covered even when a shop has not finished moving off classic Outlook. Word, Excel, and PowerPoint run through the separate Office plugin listing rather than that Outlook package.

Do You Need a Paid Teams Plan for Computer in Teams?

Yes. Perplexity’s Teams setup note says a paid Microsoft Teams plan is required for the Computer integration, in addition to a paid Perplexity seat. The Teams listing is a third Marketplace product, so installing the Word, Excel, and PowerPoint add-in does not by itself put @Computer in a channel.
