EasyChat AI
EasyChat AI is a Windows desktop client that puts ChatGPT in a native app rather than a browser tab. Free for ten daily queries, $9.99 per month unlimited, or $29.99 once with your own OpenAI API key.
What is EasyChat AI?
EasyChat AI is a Windows desktop application published by WunderApps GmbH, a company registered in Berlin, and distributed exclusively through the Microsoft Store. Its pitch is narrow and clear: replace the browser tab you keep open on ChatGPT with a native app that starts quickly and looks the part. The three things the publisher puts forward are a sleek, intuitive interface, Markdown rendering inside conversations, and a dark mode.
The app hosts no model of its own. Every request travels to OpenAI's API, and the site says so plainly, adding a footer disclaimer that the product is a third-party app, in no way affiliated with, authorised, maintained, sponsored or endorsed by OpenAI. What EasyChat AI sells is the front end and, on one plan, the plumbing behind it.
That distinction shapes the pricing. A permanent free tier allows up to ten queries a day and needs no OpenAI account at all. A $9.99 monthly subscription lifts the limit and includes the service costs, meaning the publisher pays for the model calls. A $29.99 one-off purchase, called BYO LifeTime, removes the limit too but expects you to bring your own OpenAI API key; a dedicated help page walks through creating an OpenAI account and adding at least $5 of credit to reach usage tier 1, which opens access to GPT-4, GPT-4 Turbo and GPT-4o. Both paid plans cover up to ten devices.
Privacy is handled by keeping things local: conversations and the API key are stored on the device, and the publisher states that it collects, stores, shares and publishes no personal information about your use of the app. Anonymous telemetry goes to Microsoft's Visual Studio App Center, whose servers sit in the United States.
The product is real and publicly measured. The Microsoft Store listing has been live since 28 March 2023, weighs around 68 MB and averages 4.5 out of 5 across 515 ratings. The surrounding documentation, however, is minimal: a four-page website, no terms of service of its own, and a privacy policy untouched since March 2023.

When to use EasyChat AI / When not to
A quick filter to help you decide if EasyChat AI is the right fit.
When to use EasyChat AI

- Users who want their conversations and their API key kept on their own device
When not to use EasyChat AI

Pros & Cons
Pros
- Native Windows app, installed and kept up to date by the Microsoft Store
- Permanent free tier: ten queries a day with no OpenAI account and no card
- The $9.99 monthly plan includes the model costs, so there is no API key to manage
- A $29.99 one-off option for people who would rather not hold another subscription
- Conversations and API key stay on the device, according to the privacy policy
- European publisher with a full imprint: commercial register, VAT number, director, phone
- Publicly well received: 4.5 out of 5 across 515 Microsoft Store ratings
Cons
- Windows only, through the Microsoft Store: no macOS, Linux, web or mobile version
- English-only interface, according to the Store listing
- No terms of service of its own; the site defers to OpenAI's conditions
- No DPA, no subprocessor list, no stated retention period: hard to justify in a regulated setting
- No published support address, contact goes through a form
- Very thin documentation: four pages, no demo, no annotated screenshots
- Total dependence on a third party, since without the OpenAI API the app has no function

Data, GDPR & hosting
A consolidated view of how EasyChat AI handles your data.
GDPR overview
WunderApps GmbH is established in Berlin, Germany, and publishes a complete German imprint: commercial register HRB 251510 B, VAT number DE317667553, named managing director and telephone number. The privacy policy states that the company has appointed a Data Protection Officer to comply with its obligations under EU data protection legislation, reachable at the postal address and email address given in the policy. No Article 27 representative is required, the publisher being inside the European Union. Beyond that, implementation is thin: no data processing agreement, no maintained subprocessor list, no retention period and no documented procedure for exercising data subject rights. The policy carries a single date, 29 March 2023, and has not been revised since.
Who owns the data?
The publisher states that chats and API keys are stored locally on your own device, and that it collects, stores, shares and publishes no personal information tied to your use of the app. In practice, you keep your conversations. What leaves the machine is your chat input, transmitted to OpenAI's API so the request can be answered, plus anonymous telemetry sent to Microsoft's Visual Studio App Center. WunderApps GmbH explicitly declines responsibility for how OpenAI or any third party it relies on handles that data, and points users to OpenAI's terms of service and privacy policy instead of setting rules of its own.
Reuse rights
No terms of service of the publisher's own are published, so nothing on the site restricts what you do with the answers the app produces; users are simply routed to OpenAI's API terms, which govern the generated content. On the publisher's side, chat input serves one purpose only, fulfilling the request through the OpenAI API, while Visual Studio App Center anonymously tracks version usage, feature usage and crash reports, explicitly without personally identifiable information. Training on user data is never mentioned by the publisher, in either direction. These statements come from a privacy policy in force since 29 March 2023.
Data retention & training
Hosting summary
There is little vendor-side hosting to describe, and that is the design. Conversations and the OpenAI API key are stored locally on the user's own Windows machine, and WunderApps GmbH states that it collects, stores, shares and publishes no personal information related to use of the app. Two flows do leave the device. Chat input is transmitted to OpenAI's API so requests can be answered; the publisher does not say where that processing takes place and refers to OpenAI's own policies. Anonymous telemetry — version usage, feature usage and crash reports — goes to Microsoft's Visual Studio App Center, whose servers the privacy policy places in the United States under the Microsoft Azure Service Agreement, and which the policy says collects no personally identifiable information. The publisher itself is established in Berlin, so the controller sits inside the European Union even though the telemetry does not. No hosting region, data residency option or certification is claimed anywhere on the site.
Things to keep in mind
Risks and trade-offs to weigh before adopting EasyChat AI.
- Chat input leaves your machine for OpenAI's API, which keeps it for a limited period under its own policy rather than the publisher's
- A 'lifetime' purchase lasts as long as the publisher and the API it depends on: treat it as a bet, not a guarantee
- On the BYO LifeTime plan you type a billable OpenAI API key into a third-party app; the publisher says it stays local, and that claim cannot be checked from outside
- No terms of service of the publisher's own, so the contractual relationship between you and WunderApps GmbH is essentially undocumented
- The privacy policy dates from 29 March 2023 and has not been revised since, while the practices of the underlying model provider have changed considerably
- The only age indication anywhere is the Microsoft Store rating of Teen, 13 and over; the publisher itself states no minimum age
- A chat window one click away on the desktop makes it easy to accept a fluent answer without checking it, and the app adds no sourcing or verification of its own
Setup & Integrations
Technical difficulty
Very easy on two of the three plans. Installation goes through the Microsoft Store, around 68 MB, and both the free tier and the monthly subscription work immediately, with no account to create and no key to configure. The BYO LifeTime plan asks a little more: an OpenAI account, at least USD 5 of credit to reach usage tier 1, and the resulting API key pasted into the app. That is copying a string rather than a technical exercise. Nothing is installed server-side and nothing needs administering.

Should you pick EasyChat AI?
EasyChat AI does one thing and is honest about its limits. It is a native Windows front end for OpenAI's models, published by a Berlin company that identifies itself properly — commercial register, VAT number, managing director, telephone — which is far from the norm on this part of the market. The product is verifiable rather than merely announced: it has been on the Microsoft Store since March 2023 and averages 4.5 out of 5 across 515 ratings.
Whether it is worth paying for depends on what you already have. If you hold an OpenAI API key, the one-off USD 29.99 purchase buys a permanent interface with no subscription attached. If you do not, the USD 9.99 monthly plan is the simpler route, since it covers the model costs and spares you an OpenAI account entirely. Ten free queries a day are enough to judge the app before spending anything.
The reservations concern the documentation rather than the software. There are no terms of service of the publisher's own, no data processing agreement, no subprocessor list and no stated retention period, and the privacy policy has not moved since March 2023. Anyone buying on behalf of an organisation will find little to hand to a compliance team. Individual users face a smaller version of the same question: chat input leaves the machine for OpenAI's API, which keeps it for a limited period under OpenAI's rules, not the publisher's.
Taken for what it is — a tidy, inexpensive Windows client for GPT models, from a small and clearly identifiable European publisher — EasyChat AI holds up. Expect a good interface, not a platform.
