People search for alternatives when pricing shifts, a feature goes missing, an account gets stuck, or they just want a different option. Microsoft 365 Copilot carries a 4.71 rating from about 1.3M ratings, so any replacement has a high bar to clear. Every app on this list serves the same purpose as Microsoft 365 Copilot, which means you can move over without learning a new type of tool. We rank them two ways. Embedding similarity measures how closely each app matches Microsoft 365 Copilot by what it actually does, not by keywords alone. Live App Store ratings show how real users score each one right now. For every pick you get a short read on why it is similar and where it differs, so the right choice is clear before you tap download.
How we ranked these 10 alternatives
Embedding similarity
Every app in our database carries a dense vector embedding derived from its title, subtitle, full description, and category metadata. To find apps similar to Microsoft 365 Copilot, we compute cosine distance against every other app and surface the closest 60 candidates. The similarity score shown on each pick is 1 - distance/2 clamped to [0,1] — 100% means the embedding spaces are identical, 0% means orthogonal.
Re-ranking signals
We then re-rank the candidate set using current App Store rating and review-count signals so a 4.8-star app with 100,000 reviews ranks above a 4.5-star app with 200 reviews even when their embedding distance is similar. Apps that haven't shipped an update in 12 months are filtered out before re-ranking.
Refresh cadence
The similarity cache is recomputed weekly. Live App Store data (rating, review count) is verified every 6 hours.
