Pros & Cons
Google Gemini
Pros
- Many API models have a free tier, and Flash-Lite models cost from $0.10 to $0.30 per million input tokens.
- It is built into Gmail, Docs, Sheets, Meet and Drive for Workspace customers, starting with the €6.80 Starter plan.
- The Standard edition adds VPC Service Controls, customer-managed encryption keys and data-residency controls.
- The self-serve Business edition includes connectors to Microsoft 365, HubSpot and Jira as well as Google tools.
Cons
- Licensing is fragmented across Gemini Enterprise, Workspace, consumer AI plans and the API, and Plus has no public price.
- Users report unclear usage limits and silent downgrades from Pro to lighter models.
- Several API prices are scheduled to double in December 2026 and January 2027.
- Reviewers say third-party connectors to Salesforce, SAP and ServiceNow are less mature than Microsoft Copilot's.
Microsoft 365 Copilot
Pros
- Works directly inside Word, Excel, PowerPoint, Outlook and Teams, so users don't need to switch to a separate tool.
- Grounds answers in the organization's own email, SharePoint and OneDrive data, and respects the tenant's existing security and compliance settings.
- Teams meeting summaries with action items save time for meeting-heavy teams.
- Copilot Business brought the price for organizations with up to 300 users down to $21 from $30 while keeping the same functionality.
Cons
- It is an add-on, so the per-user cost comes on top of the base Microsoft 365 license.
- Reviewers report inconsistent output quality across the Office apps.
- Some users report daily usage or message limits.
- Overlapping product names (Copilot, Copilot Pro, Copilot Business) have led buyers to purchase the wrong tier.
