Pros & Cons

M
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.

Pros

  • Reviewers repeatedly praise its natural-sounding voices and its handling of interruptions and topic changes in multi-turn calls.
  • PolyAI claims around 90% end-to-end call resolution on its largest deployments and 99.994% trailing uptime.
  • Compliance is strong for regulated industries: SOC 2 Type 2, ISO 27001, PCI DSS, GDPR, and US, UK, EU and APAC data residency.
  • Managed pricing bundles maintenance, model upgrades, integrations and 24/7 support.
  • One agent can serve voice, SMS, WhatsApp, web chat and email.
  • G2 reviewers describe support as responsive during implementation.

Cons

  • The platform has no public price, so buyers must go through a sales-led quote.
  • Some users report occasional lag or slow responses.
  • Reviewers want deeper voice analytics and reporting.
  • It can struggle with complex or unusual interactions.
  • It relies on underlying telephony providers rather than bundling a full phone system.
