TL;DR verdict: Muse and Perplexity both cost $20 a month at the main paid tier, but they do different jobs. Muse is a personal agent that carries out tasks for you — browsing, forms, bookings and follow-up work on its own secure computer. Perplexity is a research engine that answers questions with cited sources. Pick Muse to get things done; pick Perplexity to get things explained and sourced.
Bottom line: If your day is drowning in admin, Muse is the pick. If your day is drowning in research questions, Perplexity is the pick. Many people will honestly only need one of them.

What is the main difference between Muse and Perplexity?
Muse, launched by Meta in September 2026 and powered by the Muse Spark model, is built to act. You give it a goal, it makes a plan, and it works on its own dedicated secure computer — researching options, filling in forms, and asking before sensitive steps such as sending an email or paying for something. It can keep working in the background after you close the app.
Perplexity is built to answer. Every response is grounded in web sources with citations you can check, and its paid tiers add Deep Research reports, a choice of leading AI models, file uploads, and Perplexity Computer credits for heavier agentic research work. It is a search and research product first, not a general personal assistant.
How do the free plans compare?
Both are genuinely usable for free, which is rare at this level. Muse is free within a usage limit, and Meta has positioned the free tier as enough for most everyday needs. Perplexity’s free plan gives you cited answers with limits on advanced Pro searches and no full Deep Research allowance. In practice, Muse’s free tier tests whether an agent fits your life; Perplexity’s free tier tests whether cited AI search beats your normal search engine.
What do the paid plans get you?
At $20 a month the value stories diverge. Muse Power simply gives you much more agent capacity — more room for longer, heavier task runs. Perplexity Pro gives you unlimited Pro Search, regular Deep Research runs, a model picker, file uploads and a small monthly API credit. Above that, Muse Maximum at $100 a month is the heavy-user agent tier, while Perplexity Max at $200 a month targets sustained research and Computer workloads. Students should note Perplexity’s Education Pro discount at $10 a month; Muse has no equivalent education tier.
Which should you pick?
Pick Muse if your bottleneck is doing: travel and booking research that ends in an actual reservation, inbox and admin chores, comparison shopping, and tasks you want finished rather than explained. Its WhatsApp presence also makes it the easiest agent to reach from your phone.
Pick Perplexity if your bottleneck is knowing: fact-checked answers for work or study, research reports with sources you can hand to someone else, and the freedom to switch between top models for different questions.
Pick neither upgrade yet if you are still casual about AI. Both free plans are strong enough to learn on for a month before you spend anything.
Frequently asked questions
Is Muse free to use?
Yes. Muse has a free tier with a usage limit, with Power at $20 a month and Maximum at $100 a month for heavier use.
How much does Perplexity Pro cost?
Perplexity Pro is $20 a month, or $200 a year. Max is $200 a month, and Education Pro is $10 a month for verified students and educators.
Can Perplexity book things and fill in forms like Muse?
Perplexity has added Computer features for multi-step research work, but task execution for everyday life — bookings, forms and purchases with approval — is Muse’s core design, not Perplexity’s.
Which one gives sources for its answers?
Perplexity does, by design: citations are its core product. Muse focuses on completing tasks and will show its work in its browser, but it is not a citation-first research engine.
