Microsoft Copilot
Microsoft Copilot is ChatGPT-class AI baked into Windows 11, Edge, and Microsoft 365, running on GPT-5-era OpenAI models in 'Smart mode.' The free tier is unusually complete -- voice, Think Deeper reasoning, Deep Research, image generation, memory, and web search. The standalone 'Copilot Pro' was discontinued; paid Copilot now comes bundled into Microsoft 365 plans (Personal $9.99, Family $12.99, Premium $19.99). Its superpower is native OS and Office integration; its weakness is brand confusion and no dedicated consumer API.
Meta AI
Meta AI is the assistant Meta has placed everywhere -- WhatsApp, Instagram, Facebook, Messenger, Threads, a web app, and Ray-Ban Meta glasses -- powered by its open-weight Llama 4.5 models. For most people it's free and reaches them inside apps they already use, which is its single biggest advantage. A paid tier (~$7.99/mo) entered testing in mid-2026, so the 'free forever' framing is starting to erode. It's fine for casual chat and image generation but trails ChatGPT, Claude, and Gemini on hard reasoning and coding, and there's no first-party consumer API.
Microsoft Copilot edges Meta AI on aggregate — 81 vs 73.
ChatGPT baked into Windows with a genuinely strong free tier -- but there's no standalone paid Copilot anymore, just Copilot bundled into Microsoft 365. Meta AI still wins for buyers who prioritise unmatched distribution across meta's apps and ray-ban glasses. Both tools are independently scored — the right pick depends on which dimensions matter most for your workflow.
