Microsoft 365 Copilot drives AI adoption as firms explore alternatives

Microsoft 365 Copilot is an AI assistant integrated into Word, Excel, Outlook, Teams and SharePoint, answering natural‑language prompts to draft, summarize, analyze and automate routine tasks. It operates within a tenant’s security boundary, respects existing permissions, sensitivity labels and Data Loss Prevention rules, and routes requests across models from Microsoft, OpenAI and Anthropic.

Businesses consider Copilot for its productivity gains and built‑in security, but its use requires an add‑on license tied to a Microsoft 365 subscription and may face integration limits with on‑premises or hybrid email setups. As a result, vendors such as Thinkfree promote alternatives like the Thinkfree AI Office SDK, a web‑based office platform that can be deployed on‑premises, private clouds or hosted APIs. The SDK is vendor‑agnostic, integrates with any large language model, supports OOXML and ODF formats, and allows AI‑assisted document editing without moving data outside controlled environments.
