Fluent

Product Introduction

1. Fluent is a macOS-native AI writing assistant designed to integrate seamlessly across all applications, enabling real-time text generation, editing, and optimization without switching workflows. It supports cloud-based AI models (OpenAI, Google, OpenRouter) and local models for offline use, prioritizing security and flexibility.
2. The core value lies in its ability to enhance writing efficiency through a unified, context-aware interface that adapts to user needs—whether drafting emails, refining grammar, translating content, or generating responses—while maintaining strict data privacy and device-local processing where required.

Main Features

1. Fluent’s Spotlight-like Smart Panel operates universally across macOS apps, enabling instant text generation, translation, grammar correction, and content summarization via customizable hotkeys. It supports Markdown rendering for previews and can be snapped to screen edges for persistent access.
2. Users can integrate 320+ AI models via OpenRouter or self-hosted local models (e.g., Llama, Mistral) without additional software, ensuring compatibility with specialized workflows and offline environments. Custom providers like Ollama, LM Studio, and Anthropic are supported through OpenAI-compatible API endpoints.
3. Advanced action customization allows users to assign hotkeys, create variables, and chain operations (e.g., extract text from images, translate, then insert into documents) in the Unlocked version. Image-to-text processing and formatting retention ensure outputs match original document styles.

Problems Solved

1. Fluent eliminates context-switching by providing AI writing assistance directly within any active app, addressing productivity loss from juggling multiple tools. Its offline mode resolves privacy concerns for sensitive data.
2. It targets professionals, content creators, and technical users who require rapid, secure text generation and editing across platforms like Slack, Mail, and coding environments.
3. Typical scenarios include drafting client emails with tone adjustments, translating technical documentation while preserving formatting, and fixing code comments or social media posts in real time.

Unique Advantages

1. Unlike competitors limited to specific apps or cloud dependencies, Fluent works universally across macOS apps and supports both cloud APIs and locally hosted models, offering unmatched flexibility.
2. The Smart Panel’s model-switching via TAB/Shift+TAB and one-click default model selection via the menu bar enable rapid experimentation with different AI providers without interrupting workflows.
3. Competitive strengths include zero data collection, Keychain-secured API tokens, and the ability to run entirely offline via local models—features rarely combined in single writing assistants.

Frequently Asked Questions (FAQ)

1. How does Fluent ensure data privacy with cloud-based AI services? Fluent stores API keys exclusively in macOS Keychain and does not transmit user data beyond the configured AI provider, with local models processing data entirely offline.
2. Can I use Fluent without an internet connection? Yes, Fluent supports offline operation through locally installed models like Llama 3 or Mistral, which are downloadable directly within the app.
3. Which applications are compatible with Fluent? Fluent works in any macOS application that accepts text input, including native apps like Mail, third-party tools like Slack, and development environments like Xcode.
4. What customization options are available in the Unlocked version? The Unlocked version enables custom hotkeys, image-to-text extraction, unlimited action workflows, and variables for dynamic prompts (e.g., auto-inserting dates or project names).
5. Does Fluent support collaborative editing or team licenses? Current features focus on individual workflows, though team-specific API key management and bulk licensing can be arranged through direct developer inquiries.
