Comparison
Side-by-side of two AI assistants tools. Summaries are original; pricing shown is each vendor's public model, not a quote.
Microsoft Copilot brings AI assistance directly into Word, Excel, Outlook, and Teams. Its value is highest for offices that already live in Microsoft 365 and want drafting and summarizing inside those apps.
Pricing: Per seat — Per-user add-on for Microsoft 365; see vendor pricing page.
Category: AI assistants
Free trial: Not advertised
Perplexity is an AI answer engine that cites its sources, which makes it useful when an operator wants a quick researched answer they can verify rather than a black-box response.
Pricing: Freemium — Free tier plus a paid Pro plan; see vendor pricing page.
Category: AI assistants
Free trial: Yes
