The Copilot Windows app is the easiest AI assistant to launch on a fresh PC because Microsoft pins it to the taskbar by default. The friction shows up after the first prompt. The app nudges toward an Edge tab for long answers, asks for a Microsoft account when you try to save a thread, and pushes the 365 upsell every time you ask it to summarise a Word document. For people who just want a chat window that opens, reads files, and writes code, the bundled Copilot is more of a wrapper than a finished assistant.
We tested seven Microsoft Copilot alternatives on Windows and macOS, focused on what desktop users actually need: a native window that launches with a hotkey, file uploads without a paid plan, and answers that do not silently route through Bing.

Why people leave Microsoft Copilot
The first complaint we hear is the account wall. The free Copilot Windows app loads, but the second you try to do anything persistent, like saving a chat, generating an image at higher resolution, or running a longer reasoning task, it asks for a Microsoft account, then for 365. Users on r/Windows11 routinely point out that asking the assistant to read a local file routes the request through OneDrive, which the app prefers over the local file picker.
The second complaint is the model. The free Copilot pulls from a smaller GPT variant that ships fewer tokens per turn, and the long-form answers get clipped without warning. Switching to GPT-5 or o-series reasoning requires Copilot Pro at a monthly fee that lands close to ChatGPT Plus and Claude Pro, with worse context controls.
The third is the Edge handoff. Click on a citation and Copilot opens a new Edge tab, even if Chrome is the default browser. The Windows 11 release notes acknowledged this, but the fix is staged.
The 7 best Microsoft Copilot alternatives for desktop
ChatGPT — best overall Copilot replacement
The ChatGPT desktop app is the most direct Copilot swap on Windows and macOS. The native window launches with a global hotkey, attaches to a screen region or window without uploading the whole desktop, and runs voice mode without opening a browser. The free tier covers GPT-5 mini, image input, file analysis, and limited image generation. Paid Plus unlocks the full GPT-5, longer context, and Projects for grouping related chats.
Where it falls short: Free usage caps reset every few hours and the warning lands mid-response. The desktop app does not yet match Claude on long document handling.
Pricing:
- Free: GPT-5 mini, capped image and file uploads
- Paid: Plus subscription, Team and Enterprise tiers above
- vs Copilot: comparable price, larger context window and stronger code output
Migrating from Copilot: No formal importer. Most users copy active threads manually. ChatGPT can read the same DOCX, PDF, and XLSX files Copilot reads without 365 sign-in.
Download: ChatGPT desktop
Bottom line: Pick ChatGPT if you want a polished, well-supported Copilot replacement that does not push a browser.
Claude — best for long documents and writing
Claude has the largest practical context window on this list, which matters as soon as you drop a 100-page PDF or a long codebase into the chat. The native Windows and macOS apps include a global hotkey, screen capture, and Projects for keeping reference files attached across sessions. Claude’s writing is more measured than Copilot’s and rarely hallucinates citations.
Where it falls short: The free tier is tighter than ChatGPT on daily messages. Image generation is not native, image input is supported but not the focus.
Pricing:
- Free: limited daily messages with the latest Claude model
- Paid: Pro subscription, Team and Enterprise above
- vs Copilot: similar price, much better for long context and editing work
Migrating from Copilot: Copy your useful prompts into a Project, attach reference docs once, and Claude keeps them in context across new chats.
Download: Claude desktop
Bottom line: Pick Claude if you write, edit, or read long documents on the desktop and want fewer hallucinations than Copilot.
Google Gemini — best if you live in Workspace
Google Gemini does not ship a standalone Windows app, but the Chrome PWA installs to the Start menu, runs in its own window, and reads Drive, Gmail, and Calendar without an extra sign-in if you are already logged into Workspace. The 2.5 Pro tier is strong on reasoning and the free 2.5 Flash tier handles everyday Copilot tasks.
Where it falls short: No Windows-native client, so the experience is a browser window with the Chrome chrome stripped. Local file handling still goes through Drive first.
Pricing:
- Free: Gemini 2.5 Flash with daily limits
- Paid: Google AI Pro and Ultra plans, bundled with Drive storage
- vs Copilot: cheaper at the entry tier when you count storage
Migrating from Copilot: Gemini reads Office formats natively when stored in Drive. Re-prompts mostly carry over without edits.
Download: Google Gemini
Bottom line: Pick Gemini if Workspace is your daily driver and you do not need a native window.
Perplexity — best for research with sources
Perplexity is built around web search, which makes it the natural Copilot replacement for anyone who used the bundled assistant mainly as a “summarise this topic and cite sources” tool. The desktop apps for Windows and macOS run as a native window with a sidebar of past threads. Pro Search runs deeper retrieval and lets you pick between Claude, GPT-5, and open models.
Where it falls short: Free usage caps Pro Search at a small number of queries per day. The writing tone is functional rather than polished.
Pricing:
- Free: standard search, limited Pro queries
- Paid: Perplexity Pro subscription
- vs Copilot: comparable price, far better citation quality
Migrating from Copilot: No importer needed. Perplexity threads are public-by-default but you can flip them private in settings.
Download: Perplexity desktop
Bottom line: Pick Perplexity if you mostly used Copilot to look things up and wanted to trust the answers.
Le Chat — best EU-hosted option
Le Chat from Mistral runs Mistral Large, Codestral, and Pixtral models in a clean native window on Windows and macOS. The free plan is unusually generous, with multi-turn chat, file attachments, and image generation included. Servers are in the EU, which matters for organisations covered by GDPR or working with sensitive documents.
Where it falls short: The model catalogue is smaller than ChatGPT and Perplexity. The desktop app is still maturing.
Pricing:
- Free: chat, search, image generation, file handling
- Paid: Pro for higher limits and faster models
- vs Copilot: free tier is materially better
Migrating from Copilot: Re-paste prompts. Mistral models follow direct instructions well and need less prompt scaffolding than Copilot.
Download: Le Chat
Bottom line: Pick Le Chat if data residency matters or you want the most generous free tier on this list.
DeepSeek — best open-weight alternative
DeepSeek ships open-weight reasoning and coding models that run through deepseek.com or self-hosted with a small inference stack. Desktop usage is via the web app or third-party clients like Chatbox and Cherry Studio that wrap the API. The reasoning model handles multi-step problems competitive with paid Copilot tiers, at a fraction of the cost.
Where it falls short: No first-party desktop client. Some regions throttle access. The web UI is functional but lacks Copilot’s voice mode.
Pricing:
- Free: web chat
- Paid: API usage billed per token
- vs Copilot: cheaper for heavy users, especially via API
Migrating from Copilot: Best handled through a desktop wrapper like Chatbox that supports custom endpoints.
Download: DeepSeek
Bottom line: Pick DeepSeek if you want strong reasoning at near-zero cost and do not mind a web-first interface.
Poe — best for multi-model access
Poe from Quora puts ChatGPT, Claude, Gemini, Mistral, and a long list of community-built bots behind one desktop window for Windows and macOS. A daily compute allowance covers casual use; heavy use rolls into a subscription. The single-window approach makes it easy to side-by-side a question across three models.
Where it falls short: Latest models often land later on Poe than on the first-party apps. File handling is more restricted on the free tier.
Pricing:
- Free: daily compute points across models
- Paid: monthly subscription with a larger allowance
- vs Copilot: similar price, more model variety
Migrating from Copilot: Recreate a few favourite prompts as Poe bots so they are one click away.
Download: Poe desktop
Bottom line: Pick Poe if you switch between models often and want one app instead of four.
How to choose
Pick ChatGPT if you want the closest Copilot replacement with the smallest learning curve and the best desktop polish. Pick Claude if your work is reading and writing long documents on the desktop. Pick Gemini if your data already lives in Drive, Gmail, and Calendar. Pick Perplexity if you use the assistant mainly to research and cite. Pick Le Chat if EU data residency or a strong free tier is the deciding factor. Pick DeepSeek for heavy reasoning at low cost. Pick Poe if you bounce between models. Stay on Copilot only if you are deep in Microsoft 365 and value the Office side panel integration above everything else.
