How we researched and ranked AI personal assistants
Last updated: November 9, 2026
What we count as an AI personal assistant
For this guide, an AI personal assistant is software that helps one person manage everyday information and tasks: answering questions, drafting, planning, handling email and calendars, and in more advanced products, taking actions for you. We included general assistants (ChatGPT, Gemini, Claude, Copilot), device and voice assistants (Siri AI, Alexa+), a browsing assistant (Perplexity Comet) and specialist schedulers and follow-up tools (Motion, Reclaim, Lindy).
Sources
- Each vendor's official product pages, pricing pages, help centers and announcement posts, read on November 9, 2026.
- Prices were recorded as displayed for the US. If a page blocked automated reading, as ChatGPT's and Perplexity's main pricing pages did, we used the vendor's own documentation pages or help-center content instead.
- We do not use invented statistics, reviews or user counts. Marketing performance claims, such as productivity percentages, were not used in ranking.
Ranking criteria
- Breadth of help: questions, writing, planning, voice, and the ability to work across your apps.
- Personal context: memory, and access to your email, calendar and files when you allow it.
- Ability to act: scheduled tasks, background agents and app actions, with approval controls.
- Reach and fit: the platforms supported and how well it fits a common ecosystem (Google, Microsoft, Apple, Amazon).
- Accessible pricing: whether there is a useful free tier or a reasonable entry plan, and how clear the usage limits are.
- Availability: whether features are generally available or still rolling out by region or plan.
General assistants rank higher because they serve more of a typical person's needs. Specialists rank lower because their scope is narrower, but they can be the right first choice for a specific problem.
What we did not do
- We did not test the products hands-on or run benchmarks.
- We did not accept payment for placement. Rankings are editorial.
- We do not have private data on reliability or accuracy. Features and limits change often, so confirm on the official sites.
