Help. The thing you'd hope you don't need.

LinguaAI is a suite of apps for macOS, iOS, iPadOS, Apple Watch, and CarPlay. The AI-powered apps use a Bring Your Own Key model. LinguaTrans is a local-only CAT tool that requires no API keys or external connections.

01 / Setup

Where to get keys, where to enter them, and what each provider unlocks.

AI providers

Specialized providers

  • ElevenLabs (transcription): elevenlabs.io, used in Studio for Scribe transcription.
  • Deepgram (transcription): deepgram.com, used in Studio for Nova-3 transcription.
  • Stability AI (images): platform.stability.ai, used in Studio for image generation.

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.

02 / LinguaAI Pro

A macOS menubar app for AI text processing.

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.

03 / LinguaAI Studio

Your AI assistant on iPhone, iPad, Mac, Apple Watch, and CarPlay.

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.

04 / LinguaAI Terminology

A macOS utility for translators.

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.

05 / LinguaTrans

A native macOS CAT tool for professional translators.

Supported file formats

  • SDLXLIFF (Trados Studio)
  • XLIFF 1.2 (open standard)
  • TXLF (Wordfast Pro)
  • MQXLIFF (memoQ)

Key shortcuts

  • ⌃↩ Confirm + next unconfirmed (primary keystroke)
  • ⌥↓ / ⌥↑ Next / previous segment
  • ⌘S Copy source to target
  • ⌘⌥→ Insert next source tag
  • ⌘⌥A Copy all tags to target
  • ⌃⌥R Mark QA reviewed

All editor shortcuts are remappable in Preferences.

Translation memory and glossary

Per-project TM with fuzzy matching, concordance search, and pre-translate. Import CSV or tab-delimited glossaries. Sanctioned terms highlight green in the target; missing terms show a red marker on the source.

Quality assurance

Eight live QA checks: Tags, Numbers, Punctuation, Capitalization, Glossary, Whitespace, Untranslated, and Repeated Word. Non-blocking by design. Consistency Check as a dedicated tab for identical sources with divergent translations.

Suite integration

LinguaTrans hands off files to LinguaAI Pro for AI pre-translation and review, and to LinguaAI Terminology for file format conversion (Word, Excel, XML). Single-click handoffs in both directions.

06 / LinguaAI Admin

Business management on iPhone, iPad, and Mac.

What it covers

  • Clients & projects: manage your client base and track project status.
  • Invoicing: create and send invoices, track payments.
  • Finances: revenue tracking, expense management, financial overview.
  • AI insights: business analytics and recommendations powered by your chosen AI provider.

All data syncs via iCloud across your devices.

07 / Shared features

Capabilities that span the suite.

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 and 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.
