Microsoft Copilot vs ChatGPT: 2026 comparison

Microsoft Copilot and ChatGPT in brief

Microsoft Copilot and ChatGPT both offer a general assistant with free access for finding information and working with content. Their published feature lists emphasize different tasks. Copilot includes accessing connected services with permission and summarizing files. ChatGPT gives more detail on writing, spreadsheet analysis, image editing and voice conversations. Both list Web, mobile and desktop availability. The practical decision therefore rests more on your tasks, subscription requirements and data information than on the operating systems you use.

Microsoft Copilot : Microsoft Copilot helps people ask questions, search for information on the web, and generate images. It also summarizes files and accesses connected services when permission is granted.

ChatGPT : ChatGPT helps people write texts, search for information, and analyze files and tables. It also supports image creation and editing, voice conversations, explanations of concepts, and study revision.

Both meet the same need, which makes the comparison useful. We compare them on 10 verifiable criteria, using the same data as their profiles, collected from official sites.

Comparison table

Criterion by criterion

For each criterion: why it matters, each one's value and who has the edge. A criterion without data on both sides is not decided.

Free tier

A free tier lets you test the tool on your own examples before paying anything. Microsoft Copilot : yes. ChatGPT : yes. A tie on this point.

Entry price

The first paid plan, per month, gives the minimum cost of regular use; higher plans cost more. Microsoft Copilot : $9.99 per month. ChatGPT : $8 per month. Edge: ChatGPT.

Public API

An API lets you connect the tool to your software, an automation tool or an AI agent. Microsoft Copilot : not disclosed. ChatGPT : yes. Cannot be decided: data missing on one side.

Data export

Being able to get your content back avoids lock-in the day you want to switch tools. Microsoft Copilot : yes. ChatGPT : yes. A tie on this point.

Data hosting

Where data is stored matters for GDPR and client data: the EU or local processing make compliance simpler. Microsoft Copilot : not disclosed. ChatGPT : several regions. Edge: ChatGPT.

Interface languages

More interface languages make the tool easier to roll out across an international team. Microsoft Copilot : 9. ChatGPT : 60. Edge: ChatGPT.

Platforms

The more platforms (web, desktop, mobile, extension), the better the tool fits your daily routine. Microsoft Copilot : web browser, Windows, macOS, iPhone and iPad, and Android. ChatGPT : web browser, Windows, macOS, iPhone and iPad, and Android. A tie on this point.

Open source

Public code lets you audit the tool, self-host it and keep using it if the publisher changes course. Microsoft Copilot : no. ChatGPT : no. A tie on this point.

Track record

A tool launched several years ago has a longer history: less risk of sudden shutdown, more user feedback. Microsoft Copilot : launched in 2023. ChatGPT : launched in 2022. Edge: ChatGPT.

Recognition

The number of reference community lists citing the tool shows how well known it is among practitioners. Microsoft Copilot : cited in 1 list. ChatGPT : cited in 1 list. A tie on this point.

Our analysis

Microsoft Copilot, launched in 2023 by Microsoft Corporation, lists question answering, Web research, image generation and file summaries. Its ability to consult connected services with authorization may be relevant if your information is spread across services, although the record does not identify those services. ChatGPT, launched in 2022 by OpenAI OpCo, LLC, explicitly describes drafting, text improvement, spreadsheet analysis and explanations for studying. Both target general assistant needs, with substantial overlap in purpose. The useful distinction is between the workflows actually documented for each product; the supplied information does not demonstrate comparative effectiveness on any of those workflows.

Both products follow a freemium model and include a free offering. Copilot’s listed paid entry point is USD 9.99 per month through Microsoft 365 Personal, including higher Copilot limits than free access. ChatGPT lists Go at USD 8 per month, billed monthly at the US price, with prices varying by country. Its API carries separate charges. The records do not provide the quotas needed to compare the subscriptions at an equivalent workload. Copilot’s score of 63 and ChatGPT’s score of 83 out of 100 concern access and transparency. They do not measure response accuracy, image quality or user satisfaction.

Neither product is listed as open source. Copilot’s data hosting arrangements are not declared, while ChatGPT’s hosting is described as mixed. Copilot documents a CSV export of activity history. ChatGPT provides a ZIP containing history and account data, so the stated scope of the two exports differs. Copilot’s access to connected services requires authorization, but the details of that permission process are not supplied. These records also do not explain retention periods or secondary uses of submitted information. Consequently, the available evidence supports comparing declared export options, but not drawing a complete conclusion about either product’s privacy protections.

Both Copilot and ChatGPT list Web, Windows, macOS, iOS and Android availability, leaving no difference in the operating systems documented here. Copilot offers nine interface languages and ChatGPT sixty, with French and Spanish included in both. ChatGPT has a documented API; the corresponding information for Copilot is not supplied. For daily use, Copilot explicitly covers connected services and file summaries, while ChatGPT details writing, tables, voice and study assistance. Those distinctions can guide your shortlist. However, a feature omitted from one record should not automatically be treated as unavailable, and practical limits for these functions are not provided.

Depending on your situation

The right choice depends on use. For a few common situations, here are the criteria that matter and who wins (Microsoft Copilot value / ChatGPT value).

Personal use on a tight budget

Here, ChatGPT has the edge: it wins 2 of the 3 criteria that matter in this situation, namely free tier (yes / yes), entry price ($9.99 per month / $8 per month), and interface languages (9 / 60).

Business use with client data

Here, ChatGPT has the edge: it wins 2 of the 3 criteria that matter in this situation, namely data hosting (not disclosed / several regions), data export (yes / yes), and track record (launched in 2023 / launched in 2022).

Integration with your software

Neither stands out on the criteria for this situation (public api (not disclosed / yes), open source (no / no), and platforms (web browser, Windows, macOS, iPhone and iPad, and Android / web browser, Windows, macOS, iPhone and iPad, and Android)): decide with a trial.

Which one to choose?

Choose Microsoft Copilot if…

Microsoft Copilot does not lead on any measurable criterion; it is still relevant if you already use it or prefer it after a trial.

Microsoft Copilot is a reasonable fit if your priorities are asking questions, summarizing files and consulting connected services with permission. Its paid entry option may suit you if Microsoft 365 Personal is the subscription package you want. A CSV export is also a concrete consideration when retrieving activity history is part of your intended workflow.

Choose ChatGPT if…

• you value entry price ($8 per month)
• you value data hosting (several regions)
• you value interface languages (60)
• you value track record (launched in 2022)

ChatGPT fits a combination of writing, spreadsheet analysis, image editing, voice conversations and study support. Its documented API may matter if you need programmatic access, subject to separate billing. The sixty interface languages and export covering both history and account data are additional reasons to consider it when language accessibility or data retrieval forms part of your requirements.
