Microsoft 365 Copilot lists at $30 per user per month, billed annually, on top of the Microsoft 365 seat itself. To turn it on you also need Entra ID, an active E3 or E5 tenant (or Business Standard and above), and a working plan for Semantic Index rollout. For a 200-person team, the maths lands close to $70K a year before anyone has typed a prompt. That price tag has pushed a lot of IT leads to re-open the shortlist. This roundup covers seven Microsoft Copilot alternatives for business that we compared on the criteria that actually matter to a buyer: SSO, data residency, admin console depth, seat pricing, and how each one handles the SharePoint and Teams context that Copilot’s demo leans on.
We looked at each option on Android too, since a growing share of frontline and travelling users read messages on their phone before they touch a laptop. Every app below ships a real Android client, not a web wrapper, and each has a distinct answer to the “how much of Microsoft do we need to keep” question.

Why teams look past Microsoft 365 Copilot
The complaint is rarely about the model. GPT-5 through Copilot is the same model most of the alternatives ship. The friction sits around it.
The all-or-nothing tenant requirement is the most quoted reason on the r/sysadmin and r/msp threads we read. Copilot’s Semantic Index only indexes content the user already has access to, which is correct behaviour, but it also means the value is bounded by whatever your SharePoint permissions look like today. Teams with sprawling permission inheritance report Copilot returning empty answers on questions where the human knows the file exists. Rebuilding permissions before rollout adds weeks.
Seat cost per active user is the second issue. Copilot licences are per-seat, not per-active-user. IT leads report an activation rate of 30 to 60 percent inside the first quarter, which means the effective cost per weekly user often lands north of $60. Most Microsoft 365 Copilot alternatives on this list bill by seat too, but several accept mixed licensing where only the heavy users get a paid seat and the rest use a lighter tier.
Data residency in the EU. Copilot processes prompts through the tenant’s Microsoft 365 Boundary, and Microsoft published EU Data Boundary coverage for Copilot in 2024, but auditors in France and Germany still flag the reliance on OpenAI-hosted inference for parts of the pipeline. Buyers who need “processed and stored inside the EU by an EU entity” push toward Mistral or a private-deployment vendor.
Slow answer for coding and structured work. On code review, spreadsheet reasoning, and long-document analysis, Claude Sonnet 4.5 and GPT-5 (via ChatGPT Enterprise) consistently beat Copilot in our tests, especially when the input is longer than roughly 40 pages. Copilot’s context window is smaller than the raw model would allow, which is defensible for a productivity assistant but painful for legal review.
Governance depth. Copilot’s admin experience is spread across Microsoft 365 admin center, Purview, and the Copilot Control System. It works, but if you want one console with retention, audit log, DLP, and prompt policies in the same place, three of the alternatives below (ChatGPT Enterprise, Claude Enterprise, Perplexity Enterprise) do it cleanly.
The alternatives
1. ChatGPT Enterprise — best if you have already standardised on OpenAI
ChatGPT Enterprise is the direct swap for teams that liked what Copilot’s GPT-5 model does but not the surrounding Microsoft ecosystem. Unlimited GPT-5 access, longer context than the consumer tier, SAML SSO, SCIM provisioning, domain verification, SOC 2 Type 2, and the “we don’t train on your data” clause in the contract are the reasons IT teams pick it. The Team tier at $30 per user per month gets small teams to the same features minus a few Enterprise controls. GPT-5 in Enterprise is also what powers ChatGPT’s Deep Research, Advanced Voice Mode, custom GPTs, and Connectors for SharePoint, Google Drive, and GitHub.
Where it falls short: No native SharePoint permissioning depth. Connectors expose folders and sites, but you cannot rely on granular ACL inheritance the way Copilot does inside Microsoft 365. Also, OpenAI does not publish list price for Enterprise, so buyers report seat pricing anywhere from $40 to $80 depending on volume and commitment.
Pricing:
- Free: No enterprise tier free
- Paid: Team $30/user/mo (min 2 seats); Enterprise custom, typically $60/user/mo at 150 seats
- vs Copilot: Comparable or slightly more expensive at Enterprise; Team is cheaper if you skip the M365 Copilot admin add-ons
Migrating from Microsoft 365 Copilot: Prompts move over cleanly. Users lose Loop and Word/Excel co-authoring depth; they gain Deep Research and unlimited GPT-5. Plan two weeks to rewire SSO, provisioning, and Connector permissions.
Bottom line: Pick ChatGPT Enterprise if you are already standardised on OpenAI, want the strongest research and coding output, and can wire your own connector story. Skip it if your value case depends on native SharePoint permissioning.
2. Claude for Enterprise — best for regulated writing and long-document analysis
Claude for Enterprise by Anthropic is the most quietly popular pick inside law firms, banks, and consultancies in our conversations. The Enterprise tier ships a 500K-token expanded context (from Claude’s already-large 200K default), Projects for pinning a chat to a persistent set of documents, SSO, SCIM, audit logs, and role-based access. It is FedRAMP High authorised on Anthropic’s government offering and holds ISO 27001, ISO 27701, SOC 2 Type 2. Data is not used to train models, and Enterprise contracts include IP indemnity. Sonnet 4.5 handles long-document reasoning and tonal consistency better than any other model in the group, which matters when the deliverable is a 60-page memo, not a chat reply.
Where it falls short: No native image generation (you can use it with tool-use to call other models, but out of the box no). Web search is available but lags Copilot’s Bing-grounded answers on freshness. No built-in Word or Excel co-authoring; the workflow assumes users upload documents and Claude returns edited versions.
Pricing:
- Free: Individual free tier available (Team seats not free)
- Paid: Team $30/user/mo (2-seat min); Enterprise custom, typically $60/user/mo
- vs Copilot: Comparable price at Enterprise; better for pure text work, weaker on inline document co-authoring
Migrating from Microsoft 365 Copilot: Users export SharePoint documents they need Claude to reason over and upload to a Project. Sensitive content can flow through Anthropic’s zero-retention API. Two-week rollout is realistic for a 200-seat team.
Bottom line: Pick Claude for Enterprise if the work is writing, analysis, and code review over long documents in a regulated setting. Skip it if you need image generation or heavy Office file editing baked in.
3. Google Gemini for Workspace — best if you already run Google Workspace
Google Gemini for Workspace is the natural equivalent for teams on Google Workspace. Gemini in Docs, Sheets, Gmail, Meet, and the newer Vids all mirror what Copilot does inside the M365 apps. The Enterprise bundle uses the same identity and admin controls as Workspace, so no separate SSO or DLP rollout. Business tier includes Gemini 2.5 Pro access, generation quotas in Docs and Slides, Take Notes for Me in Meet, and NotebookLM Enterprise (which handles source-grounded briefing better than Copilot Notebook). Data stays in the Workspace tenant and is not used for training.
Where it falls short: Only compelling if Workspace is already your directory. Ripping out Microsoft 365 to install this is a strictly bigger project than swapping Copilot for a chat-only alternative. The Business tier caps some enterprise controls (customer-managed encryption keys, Vault ediscovery for Gemini activity) behind Enterprise.
Pricing:
- Free: Trial only inside Workspace
- Paid: Business Starter with Gemini from $8.40/user/mo (limited AI); Business Standard $17/user/mo; Business Plus $26.40/user/mo. Standalone Gemini add-on starts $22.80/user/mo on top of an existing Workspace seat
- vs Copilot: Cheaper at Business Standard; comparable at Enterprise; requires Workspace commitment
Migrating from Microsoft 365 Copilot: Not a swap, a platform move. If Workspace is not already the standard, this is a 6- to 12-month project, not a two-week Copilot cutover.
Bottom line: Pick Gemini for Workspace if the org is already living in Docs and Gmail. Skip it if switching directories is out of scope.
4. Perplexity Enterprise Pro — best for research-heavy teams that need cited answers
Perplexity Enterprise Pro is the pick for teams where “where did that number come from” is a real question. Every answer ships with clickable citations, and the Enterprise tier adds Spaces (shared research libraries), Deep Research (an autonomous multi-source report generator), SSO, SCIM, SOC 2 Type 2, and file-level references. Analysts, consultants, and journalists we spoke to use it in place of a mix of Google, ChatGPT, and Copilot, then paste cited output into their real deliverable. The Pro tier gives access to GPT-5, Claude Sonnet 4.5, Sonar (Perplexity’s own model), and DeepSeek-R1 through one seat.
Where it falls short: Not a document co-authoring tool. If your Copilot use case is “rewrite my Word draft in place”, Perplexity does not do that; it produces new text you paste back. Also no image generation, and Enterprise pricing scales fast at 100+ seats.
Pricing:
- Free: Yes, with daily quotas on advanced features
- Paid: Perplexity Pro $20/user/mo; Enterprise Pro $40/user/mo (annual, min 25 seats)
- vs Copilot: Cheaper per seat; different value shape (research, not co-authoring)
Migrating from Microsoft 365 Copilot: Straightforward. Users get citations that Copilot never surfaced, and the SSO/SCIM story mirrors ChatGPT Enterprise’s setup. Plan a week.
Bottom line: Pick Perplexity Enterprise Pro for research-first teams that need to defend where an answer came from. Skip it if you were paying for Copilot to write inside Word.
5. Le Chat Enterprise — best for EU data residency and sovereign deployment
Le Chat Enterprise by Mistral AI (rebranded Vibe by Mistral in the consumer app) is the answer to auditors who want a European vendor and European infrastructure. Mistral is French, hosts inference on EU-based infrastructure, and offers on-premise deployment for regulated buyers via Le Chat Enterprise. The product ships Mistral Large, Codestral for coding, image understanding, web search with citations, and Canvas for structured writing. SSO, audit log, and admin console are included at the Enterprise tier. For a French bank, a German utility, or any public-sector procurement that lists “sovereign hosting” as a requirement, this is the option that clears the box.
Where it falls short: Model quality on long-context reasoning still trails Claude Sonnet 4.5 and GPT-5 in our tests, though Mistral Large 2 has closed the gap significantly and Codestral is competitive on coding. Ecosystem is smaller (fewer integrations than ChatGPT Enterprise or Copilot).
Pricing:
- Free: Le Chat has a free consumer tier
- Paid: Le Chat Pro €14.99/user/mo; Team €24.99/user/mo; Enterprise custom, on-prem quoted from ~€50K/year
- vs Copilot: Cheaper for a chat-only equivalent; on-prem is the differentiator for regulated buyers
Migrating from Microsoft 365 Copilot: Two rollout paths. Cloud is a normal SSO/SCIM setup, one to two weeks. On-prem takes longer (typically six to eight weeks) but survives EU data-residency audits that Copilot’s boundary story struggles with.
Bottom line: Pick Le Chat Enterprise if the RFP has “EU hosting” or “on-premise option” as a hard requirement. Skip it if raw model quality matters more than sovereignty for your team.
6. Notion AI — best if your knowledge base is already in Notion
Notion AI takes a different angle. Rather than compete with Copilot on general reasoning, it answers questions about your Notion workspace with the pages you already wrote as context. Ask “what’s our current PTO policy” or “what did engineering ship in Q2”, and it cites the exact page and block that answered. Business tier (which includes AI) also unlocks unlimited AI usage, private team spaces, SAML SSO, audit log, and workspace analytics. For teams whose docs, wikis, and OKRs already live in Notion, this delivers a big share of what Copilot promises against SharePoint but without the SharePoint permissions maze.
Where it falls short: Only as good as your Notion hygiene. Missing or stale pages produce confidently wrong answers. Also, no general-purpose chat outside the workspace context, no image gen, no code interpreter.
Pricing:
- Free: Notion free tier, no AI
- Paid: Business $20/user/mo (includes AI); Enterprise $35/user/mo (adds SAML, SCIM, audit log)
- vs Copilot: Roughly half the price at Business; different value shape (workspace Q&A, not app-embedded co-authoring)
Migrating from Microsoft 365 Copilot: Not a swap. The winning move is running Notion AI on your Notion workspace and keeping a cheap Team ChatGPT seat for general chat. Total per-user cost still lands under Copilot for many teams.
Bottom line: Pick Notion AI if the org already treats Notion as its knowledge base. Skip it if your docs live in SharePoint and moving them is off the table.
7. Poe for Business — best if the team wants model choice on one bill
Poe for Business by Quora bundles GPT-5, Claude Sonnet 4.5, Google Gemini 2.5 Pro, DeepSeek-R1, Mistral, and a long list of specialised bots behind a single subscription. The Team tier at $20 per user per month gives shared bots, workspace admin, and centralised billing. For teams that cannot commit to one model vendor or that want power users to pick the right model per task, this is the pragmatic answer. Poe also lets you build custom bots on top of any model, which some teams use to enforce prompt policies before an answer reaches a user.
Where it falls short: Not a compliance-first product. SSO exists on Team, but audit logging and DLP are lighter than ChatGPT Enterprise, Claude Enterprise, or Le Chat Enterprise. Best treated as a productivity subscription, not a governance platform.
Pricing:
- Free: Yes, daily credit allotment
- Paid: Pro $19.99/user/mo; Team $20/user/mo (2-seat min)
- vs Copilot: Cheaper; different value shape (model choice, not app integration)
Migrating from Microsoft 365 Copilot: Fast, since Poe is chat-only. A week to move users. Retain a small Copilot footprint if inline Word and Excel authoring is non-negotiable for a subset.
Bottom line: Pick Poe for Business if the team’s biggest complaint is “I want to try a different model this week”. Skip it if procurement needs a compliance-first vendor.
How to choose
Pick ChatGPT Enterprise if standardising on OpenAI is fine and the priority is raw model output plus a clean admin console.
Pick Claude for Enterprise if the work is regulated writing, legal review, or long-document analysis and Anthropic’s IP indemnity plus 500K context matter.
Pick Google Gemini for Workspace if the org already runs Workspace. Do not switch directories to get it.
Pick Perplexity Enterprise Pro if the value case is “I need to cite my sources” and no one is drafting inside Word anyway.
Pick Le Chat Enterprise if the RFP names EU sovereignty or on-prem as required.
Pick Notion AI at Business tier if your knowledge base already lives in Notion. Pair with a cheap chat seat for anything outside the workspace.
Pick Poe for Business if the team wants model choice more than they want procurement-grade governance.
Stay on Microsoft 365 Copilot if the licence is already sunk, your SharePoint permissions are clean, and inline Word, Excel, and Outlook drafting is where the value lives. It works well when the plumbing is already in place. It just does not work well as a first AI purchase for a team not already deep in Microsoft 365.
FAQ
What is the cheapest Microsoft Copilot alternative for business?
Notion AI at Business tier ($20 per user per month, includes AI) is the cheapest full-featured option if your team already runs Notion. Poe for Business at $20 per user per month is the cheapest chat-only alternative. Perplexity Pro at $20 per user per month is the cheapest cited-research option. All three land at roughly a third the cost of Microsoft 365 Copilot before Microsoft 365 seat licences are factored in.
Is there a free alternative to Microsoft Copilot for teams?
Not for enterprise governance. Free tiers exist for ChatGPT, Claude, Gemini, Perplexity, Le Chat, and Poe, but none ship SSO, SCIM, audit log, or contractual “no training on your data” clauses at the free level. For piloting inside a small team without procurement involvement, Perplexity’s free tier is the most usable of the group because it still returns citations.
Which Copilot alternative is best for EU data residency?
Le Chat Enterprise by Mistral is the most defensible pick for a “processed and stored in the EU by an EU entity” requirement. Anthropic and OpenAI both offer EU-region deployments through their API and enterprise contracts, but Le Chat’s story is cleaner for auditors because Mistral is a French company running EU infrastructure end to end.
Can I use these Copilot alternatives with SharePoint and Teams?
Partially. ChatGPT Enterprise’s SharePoint connector reads content the connected user has access to. Perplexity Enterprise supports SharePoint through its file-import flow. Claude for Enterprise uses uploads and its API for programmatic ingestion. None of them replicate Copilot’s native SharePoint Semantic Index depth. If that specific integration is the reason you bought Copilot, keeping a small Copilot footprint alongside another chat vendor is often the pragmatic answer.
How long does a Copilot migration take?
For a chat-only swap (ChatGPT Enterprise, Claude Enterprise, Perplexity Enterprise, Poe Team), plan one to two weeks including SSO wiring, provisioning, an internal announcement, and a prompt-library port. For a platform-scale move (to Google Workspace with Gemini), plan six months minimum. For an on-prem deployment (Le Chat Enterprise), plan six to eight weeks including hardware or private-cloud sizing.
