Deep integration with Microsoft 365 apps makes AI feel native, not bolted on
Excel formula generation from plain English is a genuine game-changer for spreadsheet users
Teams meeting summaries save hours of catching up on missed calls
Free tier includes GPT-4 and DALL-E 3 image generation with no account required
Enterprise-grade security and compliance inherited from existing Microsoft 365 infrastructure

Microsoft 365 Copilot at $30/user/month is very expensive on top of existing subscriptions
Quality varies wildly across apps - Excel is great, Outlook drafts are mediocre
Standalone chat experience is unremarkable compared to ChatGPT or Claude
Cross-app intelligence promised in marketing demos often falls short in practice
Requires Microsoft 365 subscription to unlock the most valuable features

Fully open-source core — self-host, customize, and own your chatbot infrastructure completely
Visual flow builder is best-in-class among open-source alternatives and rivals paid platforms
Code-first flexibility lets developers write JavaScript/TypeScript directly inside visual nodes
Active community with 12,000+ GitHub stars and regularly updated modules and templates
Self-hosted option means your data never leaves your servers — critical for regulated industries

Self-hosting requires Docker, PostgreSQL, and real DevOps expertise to maintain
Pricing jumps from free to $495/month with no affordable middle tier for small teams
Multilingual NLP requires separate training per language and varies in quality
Complex flows with 200+ nodes can develop performance and latency issues
Cloud version has fewer customization options compared to the self-hosted edition
