Full review →What is Microsoft Copilot?
Microsoft Copilot embeds AI directly into the applications where knowledge workers spend their day. In Word, it drafts documents, rewrites sections, and summarizes content. In Excel, it analyzes data, creates formulas, and generates charts from natural language. In PowerPoint, it builds entire presentations from a prompt or document. In Outlook, it summarizes email threads, drafts replies, and surfaces action items. In Teams, it transcribes meetings, generates summaries, and answers questions about discussions you missed. Rather than switching to a separate AI tool, Copilot works alongside you in familiar Microsoft interfaces. The free Copilot Chat tier includes web search and is available to everyone. The standalone Copilot Pro plan ($20/mo) has been retired for new subscribers; its perks, priority access to the latest models and Copilot inside the Office desktop apps, now ship in Microsoft 365 Premium ($19.99/mo or $199.99/yr). Microsoft 365 Copilot ($30/user/mo add-on, annual commitment) sits on top of a qualifying Microsoft 365 plan and provides the full enterprise experience with Microsoft Graph integration, meaning the AI understands your organizational context, documents, emails, and calendar. It is the clear choice for organizations already standardized on the Microsoft stack. The tool is best suited for Microsoft 365 power users and enterprise teams. It offers a free tier alongside paid plans (Free · M365 Premium $19.99/mo · Copilot add-on $30/user/mo), making it accessible for individuals and teams alike.
What is Perplexity AI?
Perplexity AI reimagines search as a conversation. Instead of returning a list of links, it reads multiple sources in real-time and synthesizes a comprehensive answer with inline citations, every claim linked to its source. This makes it the most trustworthy AI assistant for research, fact-checking, and staying informed on current events. The free tier supports unlimited Quick Search queries and up to 5 Pro Search queries per day. Perplexity Pro ($20/mo or $200/yr) unlocks unlimited Pro Search with GPT-5, Claude, Gemini, and other advanced models, plus file upload analysis and API access (billed separately). Max ($200/mo) adds Perplexity Computer access and advanced reasoning models. Focus modes narrow searches to academic papers, YouTube videos, Reddit discussions, or writing assistance. Collections allow organizing research into shareable projects. Perplexity is particularly valuable for journalists verifying claims, researchers surveying literature, students writing papers, and professionals who need sourced answers rather than AI-generated opinions. Unlike ChatGPT and Claude which generate responses from training data, Perplexity grounds every response in live web data, making it far less likely to hallucinate on factual queries. The tool is best suited for researchers needing cited AI answers. It offers a free tier alongside paid plans (Free · Pro $20/mo or $200/yr · Max $200/mo), making it accessible for individuals and teams alike.
