EDITORIAL PICK

Le Chat

FreemiumAI chatconversational ai

Le Chat is Mistral AI's conversational assistant, built by the leading European AI lab. The free tier gives real access to flagship Mistral models plus image generation, a code interpreter, and 40+ connectors, soft-capped around 25 messages a day on the best models. Pro is $14.99/mo (students $5.99), and developers get one of the cheapest frontier APIs via La Plateforme with a free experiment tier. Its EU base makes it a credible GDPR and data-sovereignty pick for businesses that can't send data to US providers.

Microsoft Copilot

FreemiumAI chatconversational ai

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.

Freemium · Family $12.99/mo, Premium $19.99/mo. No direct consumer API (build via Azure OpenAI). As of June 2026.

● EDITORIAL VERDICT · BIGBANGINDEX

Le Chat edges Microsoft Copilot on aggregate — 86 vs 81.

The best free-tier value among the challengers and a credible EU privacy play -- just a strong second-tier model, not a frontier-beater. Microsoft Copilot still wins for buyers who prioritise generous free tier (voice, think deeper, deep research all free). Both tools are independently scored — the right pick depends on which dimensions matter most for your workflow.
