What Is Fello AI?
Fello AI is an all-in-one AI chatbot for Mac, iPhone, and iPad developed by AI Apps Brewery s.r.o., a company registered in the Czech Republic. The app aggregates major AI models behind a single native Apple interface, so you can switch between ChatGPT, Claude, Gemini, Grok, DeepSeek, Perplexity, and others without juggling multiple browser tabs or subscriptions.
MacSources recently reviewed the app, calling it a "native Apple app for ChatGPT, Claude, Gemini & more" — and that framing is worth examining. The app is not just a thin wrapper. Version 6.7.4, released in late July 2026, added Handoff between iOS and macOS, support for GPT-5.6, Claude 5, Kimi K3, Nano Banana 2, and DeepSeek V4, plus the ability to generate podcasts and create real Office files directly from chat.
With a 4.7-star average rating from over 27,000 App Store reviews, it has clearly found an audience. The question is whether that audience is getting a good deal.
The Model Lineup: What's Actually in the App
Fello AI lists support for over 20 AI models. The current roster includes:
- Text models: GPT-5.6 (Sol/Terra/Luna), Claude 5, Gemini 3, Grok 4.5, DeepSeek V4, Kimi K3, Qwen 3.7 Max, MiniMax M3, GLM 5.2, Mistral, Perplexity Online
- Image models: Nano Banana 2, GPT-Image, Flux.2, SeeDream 5, Grok Imagine
That covers every major frontier provider except Meta's Muse line, which remains US-only via the Meta Model API. Notably, the app includes Kimi K3 — Moonshot AI's 2.8-trillion-parameter flagship that launched July 16 and currently leads Arena's WebDev and Agent boards — and GLM 5.2, the strongest open-weight coding model under an MIT license.
The model list is genuinely current. Version 6.7.0 (June 25) added DeepSeek V4, Grok 4.3, and MiniMax 3 within days of their respective launches. The developer's update cadence — roughly one version every 4–5 days through June and July — suggests a team that treats model currency as a feature in itself.
What You Actually Pay: USD and EUR
This is where the value argument gets interesting. Here is the current pricing on the App Store, with calculated EUR equivalents at the July 2026 rate of approximately 0.92 EUR/USD:
| Plan | USD | EUR (approx.) |
|---|---|---|
| Weekly | $4.99 | €4.59 |
| Monthly | $11.99 | €11.03 |
| Quarterly | $24.99 | €22.99 |
| Yearly | $89.99 | €82.79 (≈ €6.90/month) |
Now compare that against subscribing to the top three AI services individually — which is what Fello AI essentially replaces:
| Service | Monthly price (EUR) |
|---|---|
| ChatGPT Plus | ~€22 |
| Claude Pro | ~€20 |
| Gemini Advanced (Google One AI Premium) | ~€22 |
| Combined individual subs | ~€64/month |
| Fello AI (yearly plan) | ~€6.90/month |
| Annual savings | ~€685/year (89% less) |
The yearly plan costs less than a single month of ChatGPT Plus and Claude Pro combined. That is a genuine price-feature gap, not rounding error.
A free tier exists but is limited to 5 questions per hour on premium models; after that, you drop to the "Free Compound" model, which routes to available AI providers based on current capacity. It is enough to test the interface. It is not enough for daily work.
The Native Apple Experience
Fello AI is built exclusively for Apple platforms — there is no Windows or Android version. It requires macOS 12 Monterey or later on Mac, and iOS/iPadOS 16 or later on mobile. The latest version supports Handoff between iOS and macOS, so you can start a conversation on your iPhone and pick it up on your Mac.
The interface follows Apple's design language: Light and Dark Mode, keyboard shortcuts (Cmd+N for new chat, Cmd+F for search), and native text rendering. The app weighs about 51 MB — light for a client that connects to half a dozen cloud AI providers. This is not Electron. It is a Cocoa/SwiftUI app.
On the feature side, Fello AI goes beyond basic chat. You can:
- Upload PDFs, images, Word, Excel, PowerPoint, iWork files, and code files (up to 16 at once, 16 MB each)
- Generate real .pptx, .xlsx, .docx, and .pdf files directly from chat prompts
- Search the web with cited, clickable sources
- Generate and edit images using GPT-Image, Nano Banana 2, Flux.2, or SeeDream 5
- Create AI-generated podcasts from PDFs, websites, or chat history
- Plan trips with a dedicated Travel Skill that checks visa rules and compares hotels
- Export conversations as PDF, plain text, or formatted Word/PowerPoint documents
The podcast and file-generation features are unusual for a third-party client. Creating an actual .pptx with charts and images from a text prompt, or turning a PDF into a podcast audio file, goes beyond what the official ChatGPT or Claude apps currently offer.
What You Lose vs. Official Apps
The trade-offs are real and the developer's FAQ is honest about them. You lose:
- ChatGPT voice mode — no voice input or output in Fello AI
- Claude's memory and project tools — no persistent Claude memory
- Gemini's Google Workspace integration — no direct Gmail/Docs/Drive access
- Code execution sandboxes — no local Python interpreter for code generation
- Real-time collaboration features — no shared chats or team workspaces
There is also an inherent latency tax: every prompt goes through Fello AI's servers, which then route to the target AI provider's API. In our production experience running AI services, that extra hop typically adds 300–800 ms to the first-token latency compared to a direct API call. It is noticeable when you switch from the native ChatGPT app to Fello AI for the same model.
One known quirk: AI models asked to identify themselves inside Fello AI will often report an older version number. This is a training-data artifact — the model training cutoff predates its own deployment — not evidence that the app is running a cheaper model. The developer explicitly documents this in its FAQ.
The app also does not connect to your existing ChatGPT, Claude, or Gemini subscriptions. If you have already paid for Claude Pro, those credits do not carry over. Fello AI is a walled garden within the AI ecosystem: everything runs through its own API keys.
The European Angle: A Czech Company with a Strong Privacy Story
This is where Fello AI gets genuinely interesting for European users. The developer, AI Apps Brewery s.r.o., is a Czech limited liability company governed by Czech law. The privacy policy, last updated February 2026, explicitly states that:
- The app collects no personal identifiers — no name, email, Apple ID, or location data
- Chat data is stored locally on the device, not on developer servers
- Prompts are encrypted before transmission to AI providers
- The app uses "no tracking or advertising identifiers" and "no third-party analytics SDKs"
On the App Store privacy label, Fello AI shows "Data Not Collected" — the best possible score. For comparison, the official ChatGPT iOS app lists three categories of linked data (contact info, identifiers, usage data) and four categories of data used for tracking.
For European users subject to GDPR, the no-collection posture is meaningful. The developer acts as a data controller under EU law, and by collecting nothing, it has nothing to breach with. The app also supports 20 interface languages including Czech, German, French, Italian, Spanish, and Polish — above average for an AI client.
The AI Act angle is less clear. As an intermediary that routes prompts to third-party AI providers, Fello AI itself likely falls outside the AI Act's high-risk classification. But the providers it connects to — OpenAI, Anthropic, Google, xAI — are all classified as providers of general-purpose AI models under the Act's transparency obligations. European users should know that any prompt sent via Fello AI to, say, Grok 4.5 is still subject to xAI's own data handling policies, which the app's privacy policy helpfully links to for each provider.
One practical note on EU availability: Grok 4.5's EU access began rolling out on July 16 but remains partial — xAI's API console is still closed to EU users under the AI Act's systemic-risk obligations, though Cursor reports availability. Inside Fello AI, Grok may work or may not, depending on which API endpoint the app uses.
Who Should Use Fello AI
Fello AI makes the most sense for three types of users:
1. The model-switcher. If your workflow involves asking Claude to write code, then asking GPT-5.6 to review it, then asking Gemini to fact-check the output — doing this across three browser tabs is slow and expensive. One app with a model dropdown is faster and cheaper.
2. The Apple-only household. If you live in the Apple ecosystem and want a single subscription that covers every device, Fello AI's $89.99/year for Mac + iPhone + iPad is hard to beat. The Handoff feature in version 6.7.4 makes the cross-device story genuinely useful.
3. The privacy-conscious EU user. If the ChatGPT app's data-collection label bothers you, Fello AI's "Data Not Collected" posture is a concrete alternative. You lose voice mode and some integrations, but you gain a client that literally does not know who you are.
It makes less sense for power users of a specific AI ecosystem — if you rely on Claude's Projects and memory features, or Gemini's Workspace integration, the official apps remain the right tool. Fello AI is a breadth play, not a depth play.
Can I use my existing ChatGPT or Claude subscription inside Fello AI?
No. Fello AI is a standalone app that uses its own API keys to access AI models. Your existing subscriptions to ChatGPT Plus, Claude Pro, or Gemini Advanced are separate and do not carry over. You are essentially paying Fello AI to access these models on your behalf.
Is the AI quality the same as the official apps?
The underlying models are the same — Fello AI routes your prompts to the actual GPT-5.6, Claude 5, and Gemini APIs. However, the prompt may go through slightly different system instructions than the official apps use, which can produce noticeably different responses for the same query. Expect equivalent capability, not identical output.
What happens to my data? Does Fello AI train on my chats?
According to the privacy policy, Fello AI itself does not collect or store your prompts on its servers — all chat history lives on your device. However, your prompts are transmitted to the AI provider you select (OpenAI, Anthropic, etc.), and each provider has its own data policy. OpenAI's API policy states it does not train on API data, but the other providers' policies vary. Check the individual provider links in Fello AI's privacy policy.
Bottom Line
Fello AI is a well-executed aggregation play from a Czech developer that understands the value of putting 20 AI models behind a single Apple-native interface at roughly the price of half a ChatGPT subscription. The model list is current, the privacy story is real, and the yearly price-to-feature ratio is the best we have seen in the AI-client category.
The trade-offs are not hidden — you lose voice, memory, deep integrations, and direct API access. But for users who want to switch between GPT-5.6, Claude 5, and Gemini without paying three separate subscriptions, the math works. At €6.90/month on the yearly plan, you are paying roughly the cost of a single kebab in Prague for access to every frontier model on the market. That is not a marketing claim. It is arithmetic.
