Outlier vs Microsoft Copilot: local Mac AI vs Microsoft's cloud

Fair warning: I built Outlier, so I'm an interested party. I've tried to write the Copilot half the way I'd want a competitor to write about me — every number below comes from Microsoft's own pages, linked at the bottom, and anything I couldn't confirm I left out rather than guessed.

What Microsoft Copilot actually is

Copilot is two different products sharing one name.

The first is the consumer app — free on the web, Windows, macOS, iOS and Android; the Mac App Store lists it as "Free · In-App Purchases," with upgrades to Microsoft 365 Personal and Premium offered inside. It's a capable chat assistant, but Microsoft is blunt about the ceiling: the free version can't access your documents or email and doesn't work inside Word, Excel or Outlook. Only subscribers get "deep integration with documents, emails, spreadsheets, calendars and more." The Mac build lags a little too — Copilot Pages and Deep Research aren't available in it.

The second is Microsoft 365 Copilot, the paid per-seat add-on for organisations — the thing that makes Copilot different from every other chatbot. Before answering, it grounds your prompt against Microsoft Graph (mail, chats, files, calendar, meetings), scoped to what your Entra ID account can already see, then "sends the grounded prompt to the LLM" in Microsoft's datacentres. As of July 2026 that model can be OpenAI's GPT-5.6 family; Anthropic's Claude models are available too, with Anthropic onboarded as a Microsoft subprocessor.

Worth knowing if you're budgeting: Copilot Pro, the standalone $20/month consumer plan, is gone. Microsoft says it "is no longer available for purchase" and support for existing subscribers ends 1 August 2026; Microsoft 365 Premium is the replacement.

What Outlier is

Outlier is a native Mac app for Apple Silicon (M1 or later, macOS 12+). You download it, it downloads a model, and everything after that runs on your machine — no account, no caps, nothing uploaded, works with Wi-Fi off.

Seven tiers, from Nano (4B, 2.37 GB, needs 6 GB RAM) through Core 27B to a 397B-a17b Plus tier that streams experts from SSD. Nano and Lite are free forever, no account. Pro is $20/month or $149/year for all seven, lifetime from $99. Core 27B matched Claude Opus on 98.9% of rubric checks across 54 prompts, and measured about 45% on a blind slice of SWE-bench Verified.

What Copilot actually costs per year

Consumer pricing as of July 2026: Microsoft 365 Personal is $9.99/month or $99.99/year for one person. Family is $12.99/month or $129.99/year for up to six. Premium is $19.99/month or $199.99/year for up to six, and includes Office with Copilot built in, up to 6 TB of storage, and agents like Researcher in Word and Analyst in Excel. Eligible existing subscribers are offered a promotional $99.99 first year.

Two catches. Personal only gets "higher usage than free for select Copilot features" — you're still metered. And on Family and Premium the AI features go to the subscription owner only; the other five people don't get them.

On the work side, Microsoft 365 Copilot is $30.00 per user per month paid yearly, or $31.50 on monthly billing with an annual commitment. That's $360 a seat a year, and it's an add-on, not a replacement: "a separate license for a qualifying Microsoft 365 plan is required" — E3/E5, Business Standard/Premium, Office 365 E1/E3/E5 or similar. Copilot Business, the small-business SKU, lists at $21.00/user/month, promotionally $18.00 on annual commitment between 1 July and 30 September 2026, first year only; $25.20 on monthly commitment.

One free path many people already have: Copilot Chat, the web-grounded version, is included with an eligible Microsoft 365 commercial subscription. Work-grounded chat — anything reading your tenant's data — needs the paid licence.

Where Microsoft Copilot genuinely wins

Plenty, and I'd be lying if I softened this.

• It reads your actual work. Graph grounding across Exchange mail, Teams chats and meetings, SharePoint, OneDrive and your calendar is something a local Mac app can't replicate. Outlier can't see any of it.
• Frontier models, no hardware bill. GPT-5.6-class models and Claude run in Microsoft's datacentres, so an old laptop gets the same answers as a Mac Studio. Outlier's quality is bounded by your RAM — Plus needs 64 GB.
• Web-grounded answers. Copilot Chat searches the live web. Outlier has no web search at all.
• Everywhere you are. Windows, Mac, iOS, Android and browser, conversations following you between them. Outlier is Apple Silicon Mac only — no Windows, no Linux, no mobile app, no sync.
• Voice and images. Copilot supports voice conversations, and Microsoft's hosted model list includes Black Forest Labs' FLUX image model. Outlier is text in, text out.
• Enterprise governance. Purview eDiscovery, retention and DLP over Copilot interactions, Conditional Access, MFA, per-group control over which AI providers users reach, plus GDPR, ISO 27001, HIPAA and ISO 42001 coverage and EU Data Boundary status. I'm one person in Grand Rapids; I can't offer that.
• Legal indemnity. The Copilot Copyright Commitment means Microsoft defends a commercial customer sued over Copilot output and pays resulting judgments, provided the guardrails were used. Outlier gives you no such backstop.

If your work lives in Microsoft 365 and the answer depends on last Tuesday's Teams thread, Copilot is the right tool and nothing local competes.

What happens to your data

Commercially, Microsoft's written position is strong: "Prompts, responses, and data accessed through Microsoft Graph aren't used to train foundation LLMs," stored interaction data is encrypted and also excluded from training, and Copilot has opted out of Azure OpenAI abuse monitoring, which includes human review of content. That's a better contractual floor than most cloud vendors put in writing.

The consumer side is weaker, and it's opt-out. Microsoft's privacy statement says it may use your data "to develop, train, and fine-tune our AI models, including large language models," and that "in some markets, this data can help train our AI models in Microsoft Copilot unless you opt out." The switches sit under Settings → Privacy. Opting out covers past, present and future conversations and propagates within 30 days — but it doesn't exclude them from use for "advertising, digital safety, security, and compliance purposes." History is kept 18 months by default. Some users are excluded automatically: work account holders, signed-out users, under-18s, and users in several countries including Brazil, South Korea and Vietnam.

Your queries may also not stay in your country. Microsoft says LLM calls route to nearby datacentres "but also can call into other regions where capacity is available during high utilization periods," and customers outside the EU "may have their queries processed in the US, EU, or other regions." Anthropic's models in Copilot are excluded from the EU Data Boundary, so EU/EFTA and UK tenants have them off by default.

Outlier's half of this is short because there's nothing to configure: the model runs on your Mac, so there's no prompt to route, no region, no retention period, no toggle to find. That's the whole pitch — and also why Outlier can't do the things listed above.

Side by side

Who should pick which

Pick Microsoft Copilot if your organisation runs on Microsoft 365 and you want answers grounded in your real mail, files and meetings; if you need compliance certifications, eDiscovery and admin control; if you need Windows, Android or a phone in your pocket; if you want the live web, voice or image generation; or if your hardware couldn't load a 27B model.

Pick Outlier if the material genuinely can't leave the machine — client files, source code under NDA, medical or legal drafts — and a contractual promise isn't the same as data never moving. Or if you work offline, or you're tired of metering, or $149/year against $360/seat/year plus a base licence changes the maths. It's Mac-only and text-only with no web search and no mobile app, and I'd rather you know that before you download than after.

One deployment note before you buy seats. Copilot surfaces whatever a user technically has permission to see, which in most tenants is more than they were meant to find. Microsoft's stopgap, Restricted SharePoint Search, is capped at 100 sites, is explicitly "not a security boundary," and is being retired — new enablement is blocked from 31 July 2026. Fix permissions first. Microsoft also notes responses "aren't guaranteed to be 100% factual."

Plenty of people run both, which is the sane answer for most Microsoft shops: Copilot for anything needing tenant data or the live web, Outlier for the confidential work and the plane rides.
