| Pros | - It is where you already work: Windows, Edge and Office, even with a Copilot key.
- In Word, Excel, PowerPoint and Outlook it genuinely saves time.
- Generous free version: chat, sourced web search, voice and images.
- Included in Microsoft 365 Personal and Family (60 AI credits a month).
| - Real-time access to what is being posted on X.
- Grok 4.7 is a frontier coding model with a competitive API ($2 / $6 per million tokens).
- Grok Imagine turns an idea into images and short videos in seconds.
- Premium ($30/month) bundles SuperGrok, Cursor Pro and X Premium+, previously about $90 combined.
|
|---|
| Cons | - Confusing plans and branding.
- In raw answer quality it usually trails ChatGPT, Gemini or Claude.
- Windows and Edge integration many find intrusive.
| - Serious content controversies and an open EU investigation (DSA).
- Not reliable as a fact-checker: it has endorsed viral hoaxes.
- Privacy failures (shared chats indexed by Google in 2025, repositories uploaded by Grok Build in 2026).
|
|---|
| Use cases | - People who already use Word, Excel and Outlook; companies in the Microsoft ecosystem; free, occasional use from Windows.
- In Word, ask for a draft based on a specific file (you can reference it with /): it will start from your own data instead of making things up and you only need to polish it.
| - Heavy X users, journalists and community managers following the news (always cross-checking); developers who use Cursor; creators of images and short videos.
- On X, reply to a post mentioning @grok to get the context, but treat it as a starting point: ask for sources and check them before sharing anything.

| Privacy and data | When signed in you can stop your conversations being used for training under Privacy > “Model training”. What you do with Copilot inside Word, Excel or PowerPoint on home plans is not used to train the base models, according to Microsoft. | Outside Europe, X uses posts and Grok interactions for training by default (turn off at x.com/settings/grok_settings). In the EU, X committed in 2024 not to use European users’ personal data for that training. |
