Getting better results from AI is all about how you ask. A clear prompt can lead to 10x better answers. Here’s how to make the most of your AI.
Each AI model has its strengths. Whether you need natural conversations, technical help, or creative ideas, these resources will help you pick the right model for the job you’re currently working on.
Fello AI is a desktop client for interacting with various AI models, including ChatGPT, Claude, Gemini, DeepSeek, Grok and more.
Unlike ChatGPT, Fello AI allows you to switch between these models seamlessly and customize your experience based on the model’s strengths.
On the top of that, Fello AI offers a wide selection of useful features such as possibility to pin your most used conversation, bookmark useful replies, search across all your conversations and more.
Fello AI supports all major AI models, including:
Each model is great at different tasks—like natural conversation, coding, internet research, or general knowledge—making Fello AI a highly flexible and powerful tool for all kinds of users.
We also keep the app updated regularly, and new models are usually added just days after their official release. This way, you always have access to the latest AI technology without switching apps.
Absolutely! Fello AI supports most spoken languages. Simply write your prompt in your desired language, and the AI will automatically recognize it and reply in the same language, making it easy to communicate in various languages without changing any settings.
Yes, your data is as secure as Large Language Models (LLMs) allow. All conversations are stored exclusively on your device, and no prompts or interactions are saved on our servers. Before any data is processed, it is encrypted to ensure privacy and cannot be linked back to you personally. However, since the LLMs themselves are not under our direct control, we recommend avoiding sharing personal or sensitive information during conversations.
Yes, a few features from the official apps aren’t available in Fello AI—for example, ChatGPT’s voice input, Claude’s memory tools, or Gemini’s integration with other Google services.
However, Fello AI offers its own powerful advantages that many users find more useful for everyday work—like:
So while some official features are missing, Fello AI gives you a faster, more streamlined way to work with multiple AI tools in one place. Depending on your workflow, it might even be the more powerful option.
Switching between AI models in Fello AI is simple. Simply click on the “Model” menu in the top right corner of the app and select your preferred model from the dropdown menu. You can choose based on model cutoff, general score from LM Arena or your personal preference.
Yes! Fello AI can analyze all kinds of text files and images—not just PDFs. You can upload up to 16 files at once in a single conversation.

Fello AI supports all the currently running MacBooks, iMacs and Macs on the market. It requires macOS 12 (Monterey) or later to run. Ensure your system meets this specification for the best performance and experience.
Fello AI is currently available only for macOS, but we’re actively working on iPhone support. It’s one of our top priorities, so stay tuned—mobile access is coming soon!
No, Fello AI is a standalone app that doesn’t require additional subscriptions. It’s a great deal for anyone looking to use the benefits of multiple LLMs at the cost of just a few cups of coffee.
Large Language Models (LLMs) are advanced AI systems trained on huge datasets, including books, websites, and articles, to understand and generate human-like text. They work by predicting the most likely next word in a sentence based on the words that came before it. This allows them to handle a wide range of tasks, from answering questions to writing essays, by recognizing patterns in the language they’ve been trained on.
The accuracy of an AI’s response depends on several factors, such as the complexity of the question and the AI model being used. Generally, popular models like GPT-4, Claude, and Gemini provide highly accurate and relevant answers for most everyday tasks. However, since these models are not perfect, they may sometimes generate responses that are incorrect or nonsensical, especially when asked about very niche or specialized topics.
AI is a powerful tool, but it’s not always 100% reliable. It generates responses based on patterns in the data it has seen—not by accessing verified facts in real time. For casual use, it works great, but for important topics (like legal, financial, or medical advice), it’s best to double-check information from trusted sources.
The quality of AI responses depends a lot on how you write your prompt. Here are some simple tips to improve your results:
Clear, thoughtful prompts lead to better answers every time.
AI models like ChatGPT, Claude, or Gemini are trained on data up to a specific cutoff point, which is clearly marked in the app. This is technical limitation which nothing can be done about. Unfortunately, LLMs don’t receive real-time updates, so they might not be aware of events that happened after their training. Some models, like Perplexity Online, can access real-time information, but most do not.
This can happen when the Apple App Store doesn’t correctly recognize your active subscription. It’s not a problem with the Fello AI app itself, but a sync issue between your device and Apple’s servers.
To fix it, please try the following:
These steps usually resolve the issue. If it still doesn’t work, we recommend contacting Apple Support directly to confirm your subscription status.
No, Fello AI is a completely independent macOS app and does not connect to your existing subscriptions from OpenAI (ChatGPT), Anthropic (Claude), or Google (Gemini). You don’t need separate subscriptions—Fello AI includes access to these models through its own system.
Subscription management is handled by Apple, not the developer, so you’ll need to cancel it yourself through the App Store. If you’d like to cancel your subscription, you can follow the Subscription Cancellation Guide.
Fello AI offers a free tier that includes essential Q&A capabilities. In this tier, you can ask a limited number of questions, which reset every 4 hours. For full access to all features, including PDF and image recognition, we offer the following paid plans:
We understand that costs matter, and that’s why Fello AI is one of the most affordable options, giving you access to several top-tier AI models in one app. Our pricing simply supports ongoing improvements and new features, so you’re always getting the latest in AI technology. Prices might slightly vary based on your region.
Yes, Fello AI includes a free tier where you can ask a limited number of questions, resetting every 4 hours. Please note that advanced features, like PDF and image recognition, are only available in the paid plans.
Fello AI doesn’t require you to pay for each AI model separately. Instead, we pay the AI providers (like OpenAI, Anthropic, Google, etc.) based on how many queries you actually make.
Most users only make $5–10 worth of queries per month, even when using advanced models like ChatGPT 4o or Claude 4. Because of this, we’re able to offer Fello AI at a much lower flat rate—without limiting your experience.
In short, you’re sharing costs with other users, which makes it far more affordable than paying for individual subscriptions to each AI model separately.
Fello AI is a powerful macOS chatbot, that let you use all top AI Models like GPT-4o, Claude 4 Sonnet, DeepSeek, Perplexity and Gemini 2.5 Pro in one place!
