Fluent: The sweet AI companion we now use across our Mac

We’ve tested AI companion apps from nearly every major provider — Perplexity, ChatGPT, and more. While they’re powerful, most still don’t understand what we’re actually doing on our Mac.

If we’re browsing a webpage or working inside a document, that context rarely carries over. We’re left copying and pasting content between tabs, apps, and windows.

We kept wondering: what if one AI tool could use multiple models and actually understand what’s happening on our screen?

That’s exactly what Fluent claims to do — so we put it to the test.

What Is Fluent for Mac?

Fluent for Mac calls itself an “AI assistant that walks inside every Mac app.” It differs from other AI-based assistants in that Fluent doesn’t rely on a single AI model. Instead, you can bring your own AI model, including ones from OpenAI, Google, Anthropic, etc.

The app also packs several context-aware features that ensure both input and output take into account what’s on your screen. Thus, Fluent promises an impressive AI assistant experience on your Mac. Fluent has made this possible through a feature called Smart Panel, which, similar to Spotlight, appears on command.

Fluent App Hands-on Review

We wanted to test how useful Fluent and its contextual AI assistant are in real life. We have been using it on our M2 MacBook Air, which is running the latest version of macOS Tahoe. Setting up Fluent meant a few things, though.

• We uninstalled all other AI assistant apps from our Mac.
• Since Fluent uses the BYOM model, we got API plans from Anthropic and OpenAI.
• We also wanted to check the performance through offline AI models via Studio LM.

Next, a review of the experience with all these options. As with other tools, your experience would vary widely depending on the environment. However, we wanted to check how viable an alternative Fluent is for all things AI on our Mac.

Setup, User Interface, and Experience

The setup process is simple for technical users, but non-technical users may find API configuration and model selection slightly overwhelming at first.

Setup

As we mentioned earlier, Fluent does not have a subscription or any built-in AI model. Instead, it expects you to bring your own AI model. You can do it via:

• APIs
• Running LLMs locally using apps like Studio LM
• Relying on Apple Intelligence

We should also clarify that the API method is the most efficient one, especially if you have a low-performance Mac.

We tested the process with all other options, and running LLMs locally with Studio LM or Apple Intelligence takes up a lot of resources.

Even though you can use a free tier plan for testing, you’d need a paid plan to get a decent AI assistance experience in the long term. We configured the APIs for Anthropic (Claude) and OpenAI (ChatGPT), and we were good to start.

The UI

We found the user interface to be impressive from the get-go. Most of the things that you do with Fluent happen through the smart panel that appears, similar to how Spotlight or Raycast appears on top of the screen.

However, there is a settings pane you can access to manage options such as models, actions, and other shortcuts.

This settings window also lets you customize a hell out of Fluent and the AI assistance experience across all the applications. For instance, you can explore how Memory works and set up a variety of MCP integrations. There are also options to explore features like history and blacklisting.

Experience

Overall, we wouldn’t call this experience beginner-friendly; however, compared to how difficult it is to build an AI assistant tool, it is. Setting up and customizing Fluent for your AI assistant needs is pretty straightforward.

Core Features Check

Here is what we think of the core features Fluent offers. Of course, we do not want to give you a list of features; instead, we will discuss how effective these features are at providing a unique AI-assistance experience across your Mac.

Smart Panel

As we said earlier, a Smart Panel is where all the magic about Fluent happens. This works as an overlay that appears on top of everything that you are working with; however, it smartly captures the context of what you are working on. Whether it’s a webpage, document, or native app, Fluent captures the visible context and routes it directly into your AI prompt.

Here’s an example:

We’re on the Fluent page, looking at the Pricing section. When we bring up Smart Panel and ask, “Which plan is more cost-effective?”, we don’t have to specify anything. Instead, Smart Panel considers the webpage as the context and gives us a relevant response. On other AI apps, we would have to copy and paste the webpage URL to get the same response.

Like other aspects of Fluent, the Smart Panel is also pretty customizable. You can customize how it appears, how it behaves, and how your actions will affect the behavior. You can also Pin and Unpin the Smart Panel interface as you wish.

AI Model Support

Fluent offers native support for over 500 AI models that you can set up using API keys. You get native support for providers such as Google, Anthropic, Perplexity, OpenAI, Grok, OpenRouter, etc.

Apple Intelligence is a smart option if you don’t want to spend anything further to bring AI capabilities to your assistants. You simply have to enable Apple Intelligence on your Mac to use this feature.

The other option is to use Local LLMs, which work through applications like Studio LM. We tried this option, but the problem is the amount of pressure the local LLM would put on your Mac. As a result, you may experience slower responses when multitasking, compared to using a paid Google or Anthropic API key.

Context Awareness

While the ability to switch between multiple AI models and platforms is impressive, context awareness makes Fluent a unique option for your AI needs. Once you enable Application Context and Browser Context in Settings, Fluent captures the screen context in real time. Here’s how it works:

Let’s say that we’re watching a YouTube video. Now, if we want a summary of the video, we can simply ask Fluent to provide one. Fluent will understand the page we have open and provide us with a detailed overview, thanks to its integration with YouTube.

Similarly, if we want the AI to respond based on a particular document, we can upload it and chat with it. Similarly, when we have a Google Docs document open on a browser, the responses will be based on that context as well.

In our testing, context capture was accurate in most browser and native app scenarios, though occasional misreads can happen depending on the model used.

Actions and Customization

Fluent also lets you create easy-to-access actions that you can add to the Smart Panel favorites. Alternatively, you can configure keyboard shortcuts for these actions and launch them right away. This is great if your workflow involves repetitive actions.

For instance, we can launch this action to get a list of synonyms. We just have to ensure that we have selected the text.

MCP and Memory (RAG)

You can bring additional capabilities to the AI Engine using MCP and RAG Memory.

• MCP, which stands for Model Context Protocol, allows you to connect to over 7,000 external MCP servers and get agent tasks done.
• The Memory section of the Fluent App allows you to add certain aspects to the Engine Memory. These elements will be used when the AI Engine gives you a response.

For instance, we can add an About Me section that shares some instructions. Similarly, we can add documents to a folder to customize the writing style and response.

We found both tools impressive while setting up an optimized workflow.

Privacy

The customization features built into Fluent also help you ensure optimal privacy according to your requirements. For what it’s worth, the application does not collect, process, or store any kind of data except when you are verifying the license code. Even when it comes to history, everything stays encrypted, and the memory files you add are stored on your device.

Fluent Pricing

Fluent is a premium app available for macOS. You can choose between three plans: Basic, Standard, and Team.

• The Basic plan gives you access to one Mac, offers lifetime upgrades, and costs $49.
• The Standard plan gives you access to two Macs and costs $69.
• The Team plan costs $29 per Mac, with a minimum of 3 devices.

The company offers a 30% discount to educational institutions, teachers, and students. We found this pricing plan keeps long-term costs far below subscription-based alternatives.​ But keep in mind that ongoing API usage costs will depend on the models you choose and how frequently you use them.

Fluent is the most technically capable option in this group — particularly in RAG and MCP integrations. However, users who prioritize simplicity or built-in browsing may prefer MindMac.

Who Should Use Fluent? (or not)

Fluent is great for:

• Mac-native power users who want AI assistance across every application without switching windows.
• Writers and content creators who need in-context rewriting, tone control, and prompt shortcuts within their existing workflow.
• Privacy-conscious users who prefer local model support (Ollama, MLX, LM Studio) with no telemetry or cloud dependency.
• Developers and technical users who can leverage MCP server integrations and dynamic prompt variables.
• AI hobbyists and researchers who want access to 500+ models through their own API keys without being locked into a single provider.

Who should skip Fluent?

If you just want a simple, pre‑configured AI chatbot with no setup or API management, Fluent is probably overkill.

Pros and Cons

Pros

• Works instantly in any macOS app via a system-wide Smart Panel.
• Supports 500+ AI models via BYOK, including all major providers and local models.
• Persistent RAG memory and MCP support give it a significant capability edge over competitors.​
• Native Swift build ensures fast, lightweight performance on both Apple Silicon and Intel Macs.​
• One-time purchase with lifetime upgrades.

Cons

• Exclusively macOS — no cross-platform access.
• Need to manage API keys.
• No built-in web browsing, voice input, or image generation, limiting it to text-focused workflows​.

TheSweetBits Verdict

In daily use, Fluent proved to be one of the most capable system-wide AI tools we’ve tested on macOS, and we don’t have to worry about shifting between applications or Windows.

We also found that using the API method is far more effective than purchasing these pro plans. As it happens, many paid plans from ChatGPT and Cloud may limit the AI models that you can use, but that doesn’t happen when you purchase an API.

Overall, Fluent is best for Mac power users who don’t mind API setup; but not ideal if you want plug‑and‑play, cross‑platform, or built‑in browsing/voice/image.
