Bring Your Own Key: Every LinguaAI app connects directly to AI providers using your own API keys. No intermediary servers, no data collection, no subscriptions. You pay providers directly for what you use.

Setting Up API Keys

AI Providers

Get API keys from the providers you want to use:

Specialized Providers

Where to Enter Keys

Each app has a Settings or API Keys section. Keys are stored securely in your device's Keychain and sync across devices via iCloud Keychain. Set up once, works everywhere.

LinguaAI Pro

Overview

A macOS menubar app for AI text processing. Select text in any app, trigger a shortcut, and get results instantly. No context switching.

Keyboard Shortcuts

  1. Select text in any application
  2. Press your keyboard shortcut
  3. LinguaAI processes the text with your assigned prompt

Configure shortcuts and their assigned prompts in settings. There are no default shortcuts. You create the ones that work for your workflow.

Menubar Access

Click the LinguaAI icon in your menubar to access the full chat interface, manage prompts, switch models, and configure settings.

Virtual Machine Usage

Running Windows through Parallels or another VM? Three-key shortcuts may not trigger when the VM is in focus.

Solution: Use two-key shortcuts instead. For example, use ⌃T instead of ⌃⌥T. Make sure your two-key combinations don't conflict with shortcuts in your Windows applications like Trados or MemoQ.

LinguaAI Studio

Overview

Your AI assistant on iPhone, iPad, Mac (Catalyst), Apple Watch, and CarPlay. Three main sections:

Chats

Multi-model conversations with Claude, GPT, Gemini, Perplexity, and more. Access your full prompt library, switch models mid-conversation, and use personal styles to shape responses.

Transcribe

Real-time audio transcription in 16+ languages via ElevenLabs Scribe and Deepgram Nova-3. AI cleanup handles punctuation, paragraphs, and formatting automatically.

Studio

Create and transform text with AI. Use steering presets for long-form content generation, or run chained prompts to transform source text. The second prompt receives the result of the first, like a pipeline.

Shortcuts Integration

Studio provides App Intents for Apple Shortcuts, so you can process text through AI from the Share Sheet, create automations, or trigger AI tasks with Siri.

LinguaAI Terminology

Overview

A macOS utility for translators that combines AI-powered terminology extraction with local file conversion tools.

Terminology Extraction

Feed source text or documents and let AI extract terminology with translations, context, and definitions. Export to standard formats for use in your CAT tools.

File Conversion

Convert between translation file formats locally. No upload to external services required. Supports common formats used in the translation industry.

LinguaAI Admin

Overview

Business management from one app, available on iPhone, iPad, and Mac. Track clients, projects, invoices, and finances with AI-powered insights.

What It Covers

All data syncs via iCloud across your devices.

Shared Features

Prompt Library

Save frequently used prompts for quick access. Your prompt library syncs via iCloud across all devices and apps.

Personal Styles

Define custom response styles to match your preferences. A "concise" style for brief answers, a "technical" style for in-depth explanations, or anything in between.

Model Selection

Switch between AI models and providers freely. Use Claude for one task, GPT for another, Gemini for a third. Each prompt or conversation can use a different model.

Extended Thinking

Enable extended thinking mode for complex problems requiring deeper analysis. Available for supported models.

Web Search

Grant AI access to web search for queries requiring real-time information.

Prompt Caching

For supported models (Claude and GPT), enable prompt caching to reduce costs and speed up responses.

Privacy & Security: Your data never passes through intermediary servers. API keys are stored in your device's Keychain. All AI requests go directly from your device to the provider. LinguaAI cannot access your prompts, conversations, or API keys.

Also Available

We also build apps outside the LinguaAI productivity suite. The Verdict (rate cinema and streaming with friends) and Sillage (fragrance collection and AI-powered daily picks) are available on the Also Available page.
