Microsoft Edge is sunsetting its year-old Copilot Mode, replacing it with a trio of AI capabilities that can analyze open tabs, tap into browsing history, and operate under stricter privacy controls. The change, announced May 13, 2026, marks a strategic retreat from a broad, always-on AI assistant to a more modular and consent-driven model—one the company claims better aligns with user expectations around transparency and control.

The move arrives as browsers compete intensely on AI integration, with rivals like Chrome and Brave pushing their own intelligent features. Edge’s Copilot Mode, launched in mid‑2025, attempted to unify AI assistance directly into the browser frame. But early feedback exposed friction: many users found its omnipresence intrusive, and enterprise administrators balked at the default inclusion of browsing data in AI reasoning.

The Short Life of Copilot Mode

Copilot Mode debuted as a sidebar‑integrated copilot that could summarize pages, answer questions about on‑screen content, and even perform actions such as filling forms. It relied on a persistent connection to Microsoft’s cloud AI, processing the current page’s text and images to offer contextual help. Within weeks, privacy advocates raised concerns about whether the feature could inadvertently share sensitive information—particularly when users visited banking sites or internal corporate portals.

Microsoft attempted to address these worries with configuration toggles and enterprise policies, but the damage was done. Forum discussions on sites like Windowsforum.info and Reddit’s r/MicrosoftEdge captured a recurring sentiment: “Why would I let an AI read every page I open? The old Copilot sidebar was bad enough, but this feels like a privacy landmine.” Despite usage nudges and interface refinements, adoption plateaued, and IT admins began disabling the feature via group policy.

In a blog post accompanying the May 13 announcement, Microsoft’s Edge team admitted that “Copilot Mode was a bold experiment, but user trust demands more granular control. We’re retiring it in favor of features that let you decide exactly when and how AI gets involved.” The retirement takes effect via an automatic update (Edge 136.0.3220.0) rolling out over the next two weeks; users who still have Copilot Mode enabled will see it replaced by the new components.

What’s Replacing It: Cross‑Tab AI and History Access

The three new features—Cross‑Tab Reasoning, History‑Aware Assistant, and Per‑Session AI—are designed to be independently activated and each requires explicit opt‑in. They appear as distinct buttons in the Edge toolbar and sidebar, each with its own permission prompt.

Cross‑Tab Reasoning

Cross‑Tab Reasoning allows the AI to analyze the content of all open tabs to answer questions that span multiple pages. For example, a user shopping for a laptop could ask, “Compare the specifications of the three models I have open,” and Edge would pull data from each tab’s product page to generate a side‑by‑side comparison. Technical documentation suggests the feature uses on‑device summarization for each tab, sending only condensed vectors to Microsoft’s servers for cross‑referencing, though full page text may still be transmitted in certain queries.

The feature only considers tabs within the same window and won’t peek into private (InPrivate) windows, guest profiles, or application‑isolated tabs. After hearing early tester concerns, Microsoft also added a “tab exclusion” list where users can mark tabs—like their email or healthcare portal—as off‑limits to AI.

History‑Aware Assistant

Perhaps the most ambitious—and controversial—new capability is History‑Aware Assistant. When enabled, the AI can search your local browsing history (up to the last 90 days of full URLs and page titles) to answer retrospective queries. Think “Find the recipe I viewed last Tuesday” or “What was that research paper about battery technology I opened last month?”

Microsoft emphasizes that any history access is transient: “Edge never uploads your full history to the cloud. Queries are processed locally to match against your history database, and only the selected result snippet is sent to the AI if you choose to summarize it.” Additionally, the feature excludes history entries from InPrivate windows and respects Microsoft Edge’s built‑in password manager separation, ensuring credentials are never included.

Enterprise administrators gain new policies to disable history access entirely or force it to remain off by default, addressing compliance departments that flagged even local processing as a potential risk under data retention regulations.

Per‑Session AI

Replacing the always‑listening Copilot Mode, Per‑Session AI is a lightweight assistant that can be turned on for a single browsing session. It offers page summarization, Q&A about the current tab, and text rewriting, but its memory evaporates when the session ends. This approach mirrors Safari’s transient AI mode and avoids the “spooky” feeling of a persistent companion.

Per‑Session AI runs with minimal permissions and does not require history or cross‑tab access, making it the easiest feature for privacy‑conscious users to adopt. Microsoft says it will be the default recommendation during onboarding.

Privacy at the Forefront: New Controls

Accompanying these feature releases is a revamped privacy dashboard within Edge settings. Labeled “AI & History Controls,” it provides a single pane to manage every AI‑related data flow:

  • A master toggle to completely disable all AI features.
  • Individual switches for Cross‑Tab Reasoning, History‑Aware Assistant, and Per‑Session AI.
  • A “Data processed” counter showing how many prompts and how much text have been shared with Microsoft’s servers over the past 30 days, broken down by feature.
  • A one‑click “Clear all AI data” button that wipes locally stored inference vectors, query history, and AI‑generated content snippets.
  • Granular site‑by‑site AI exclusion settings, which replace the previous binary allow/block list.

Early test builds also introduce a “Privacy Label” on AI‑generated answers: a small badge that indicates whether the response drew from local tabs, browsing history, or the public internet. If both tabs and history were used, the label shows a combined icon, and hovering reveals which specific sources contributed.

These controls will ship in the same Edge 136 release that retires Copilot Mode. Users updating from an older version with Copilot Mode enabled will be guided through a one‑time setup screen asking them to choose which, if any, new AI features to activate.

How It Works: Technical Underpinnings

Under the hood, Edge’s new AI features leverage a combination of on‑device and cloud models. Microsoft’s documentation reveals that Per‑Session AI and the initial summarization step for Cross‑Tab Reasoning run on the local device using a compact version of the Phi‑4 model, optimized via ONNX Runtime. This allows quick, private analysis of page content without sending every keystroke to the cloud.

When Cross‑Tab Reasoning or History‑Aware Assistant need to access the tab set or history index, a local service—dubbed “Edge AI Broker”—handles the request. The broker keeps all sensitive data on disk and only transmits an anonymized query vector to Microsoft’s cloud for final reasoning. Microsoft claims to have achieved a >95% recall rate for “Find that page” history queries within 500ms on a mid‑range laptop, relying on a hybrid BM25 and embedding search over a SQLite database that’s updated in real time as you browse.

For enterprise customers, all cloud calls can be routed through Microsoft’s Azure OpenAI Service on their own tenant, satisfying data residency and compliance requirements. Group policies allow IT to specify whether AI features use the consumer cloud endpoint, a tenant‑isolated endpoint, or are completely blocked.

The Competitive Landscape

Edge’s pivot arrives as the browser‑AI arms race intensifies. Chrome’s “Help Me Write” and “Tab Organizer” rely on Gemini models, while Brave’s Leo AI assistant emphasizes on‑device privacy with a local LLM. Even Firefox has begun experimenting with AI‑powered search via a partnership with Hugging Face. By offering modular, consent‑driven features, Microsoft hopes to attract users who want AI assistance without sacrificing the boundaries they expect from a browser.

Analysts note that the previous Copilot Mode put Edge at a disadvantage because it bundled too much into one opt‑out package. “People aren’t afraid of AI, they’re afraid of AI that they can’t control,” said Dr. Elena Torres, a UX researcher specializing in AI transparency. “Edge’s new approach mirrors what users have been screaming for: granular permissions, clear indicators of when AI is active, and a simple off switch.”

User and Industry Reaction

Early feedback on the Windowsforum.info community has been cautiously optimistic. One longtime Edge user wrote: “I disabled Copilot Mode day one because I couldn’t trust what it was reading. With the new system, I’ll probably turn on Per‑Session AI for work research and leave the rest off. It’s a fair trade.” Another commenter from an IT department noted, “The new GPOs for history access are a lifesaver. We can finally deploy Edge with AI features and not get flagged during a compliance audit.”

However, not all responses are positive. A handful of power users lament the loss of Copilot Mode’s unified interface, arguing that juggling three separate AI tools adds complexity. “Instead of one button, now I have three blinking icons in my toolbar. And I have to remember which one reads my history versus just the page. They’ve swapped a privacy problem for a usability problem,” posted a user on Twitter.

Microsoft seems to anticipate such criticism. The blog post promises upcoming “smart recommendations” that will automatically suggest the most appropriate AI tool based on detected workflow patterns, and a future update will allow grouping the AI buttons into a single flyout menu.

What’s Next for AI in Edge

Microsoft’s roadmap hints at deeper AI integration that still respects user consent. By late 2026, Edge is expected to support AI‑generated “smart collections” that can group related tabs, bookmarks, and history entries into a shared contextual space—again, only when manually triggered. There’s also talk of a “scheduled AI assistant” that can periodically summarize your open tabs and deliver a digest to your notification center, but only during designated work hours that you define.

For now, the retirement of Copilot Mode and the introduction of these three new features mark a maturing phase for AI in browsers. The message from Redmond is clear: AI is a tool, not a companion. And the tool should work only when you pick it up.

Microsoft has set up a dedicated feedback hub for the new AI features, where users can vote on upcoming privacy controls and feature requests. They promise to publish bi‑weekly transparency reports detailing how much data each feature processes and any incidents of unintended access—a move that may set a new standard for AI transparency in consumer software.

Edge’s 136 update is available starting today via Windows Update, with automatic rollout completing by May 27, 2026. Users can manually trigger the update from the Edge’s “About” page or download the latest installer from the Microsoft Edge Insider website.
