Microsoft Copilot Overview: an In-App Sidekick in Word, Excel and PowerPoint - Strengths, Limits and Costs

In Word, selecting text brings an overlay (writing suggestions, visualise as a table, make formal - three variants, Insert below or Replace). In Excel it answered "videos with above 10 comments" across A1:P469 and ignored a total row on its own. In PowerPoint "create a thank you slide" added bullets he did not want, so he deleted them - the human stays the briefer and reviewer. One Word request returned "sorry something went wrong".

Strengths named: native in Microsoft 365, zero learning curve, context-rich (files, chats, emails, calendar). Weaknesses: unusable inside Notion or Slack, organisational cost, a personal plan at INR 689/month with roughly 60-70 credits ("used up in a week" for a heavy user), no custom-GPT store and limited agent customisation.
