Which AI assistants work well as a desktop app on Windows?

Last verified 2026-10-15Paid placement never changes our picks.

Short answer

As of October 2026, start with ChatGPT if you want chat, an agent and coding in one Windows app, Microsoft Copilot if you already work in Microsoft 365 apps, and Ollama if you want models running on your own PC. The catch: several agent features reach Mac first, so check what works on Windows.

    Windows x64 download on the home page. Commercial-use terms were not readable on the pages we checked.

Prices come from each tool's fact block. "See pricing page" means we have not confirmed the number on the official pricing page in the last 30 days, so we do not show one.

How to choose

  • If you already use an assistant → install that vendor's own Windows app (ChatGPT, Claude, Gemini, Copilot and Perplexity all publish Windows downloads, and chats sync with web and mobile).
  • If you want a pop-up shortcut over your work → Gemini (Alt+Space, configurable) or Claude's Quick Entry; Perplexity offers a floating task bar.
  • If you want the agent to work with files on your PC → ChatGPT Work (local files and desktop apps with your permission) or Perplexity (folders you approve); Gemini and Perplexity list some of these features as Mac-first.
  • If your files must stay offline → Ollama, LM Studio or Jan (they run models on your own hardware; the cloud apps need an internet connection, and local speed depends on your GPU and memory).
  • If budget matters → every cloud app has a free account level; the newest agent features usually sit on paid plans, so compare on each vendor's page the day you buy.

How we checked

  • 7 of 7 picks have a Toolsfine fact block.
  • 7 of 7 picks had their pricing checked on the official site in the last 30 days.
  • 1 of 1 models also suggested ChatGPT.Panel: Claude (2026-10-12).

"Not checked" means we could not open that directory's page; it does not mean the tool is missing there.

Where sources disagree

  • Fairness disclosure: Claude is built by Anthropic, the maker of the model that drafted this page; held to the same standard. Anthropic rows use the same fields and plain wording as the others, and ranks follow the reader's situation, not preference.
  • ChatGPT plan access and prices: chatgpt.com/pricing lists limited Work access on desktop for Free while a help article reserves Work for eligible paid plans; plan amounts did not render, so no ChatGPT price is shown.
  • Claude agent features on Windows: Claude's download page lists Windows x64, Arm and Microsoft Store installers, but the former Cowork page we read named only a macOS download. Confirm before relying on agent features.
  • Mac-first features: Gemini lists screen sharing, dictation and local folders as macOS today, and Perplexity's installed-app control is Mac-only. Neither gives a Windows date.
