Microsoft Bot Framework vs Microsoft Copilot

Microsoft Bot Framework and Azure AI Bot Service provide tools to build, test, deploy and manage intelligent bots. The modular SDK includes tools and templates for bots that can use speech, understand natural language and handle questions and answers. Development tools work with a Connector service for messages and events, alongside Azure deployment and channel configuration. Client libraries are available for C#, JavaScript, Python and Java. Bots can connect to channels such as Microsoft Teams, Facebook and Slack, using Azure AI Bot Service channels or channel adapters; a visual flow builder, knowledge-base answers and human handoff are listed capabilities. The Free plan costs nothing and includes unlimited standard-channel messages and 10,000 premium-channel messages per month. S1 includes unlimited standard-channel messages, with no price listed. Microsoft says the SDK is no longer maintained and recommends the Microsoft 365 Agents SDK for new agent development. It also says Bot Framework SDK support tickets will no longer be serviced as of December 31, 2025.

Microsoft Copilot is an AI assistant available on the web, Windows, macOS, iOS, and Android. It supports web search, file uploads, image generation, app integrations, team workspaces, and AI bot generation. A free plan offers limited access subject to capacity and usage limits.

Paid plans provide increased usage for chat and visual AI assistance, with agentic AI usage limited on Premium and highest on Pro. AI-generated audio is English only.
