Foundational

Context-Aware Text Translation

Fluid, multi-paragraph translation with terminology consistency.

Translate single phrases or entire essays without losing nuance. Built-in language auto-detection and custom glossary support keep industry terminology precise across sessions.

Core Capabilities

  • Automatic source language detection across 380+ languages
  • Custom terminology and persistent glossary matching
  • Split-screen comparison and one-tap clipboard copy
  • Keyboard shortcuts and menu bar integration on macOS

Camera & Image OCR Translation

Instant optical character recognition with layout overlay.

Point your camera at street signs, menus, instruction manuals, or screenshots. Text is detected, translated, and rendered directly over the original image with matched typography and sizing.

Core Capabilities

  • Live camera viewfinder detection and static photo translation
  • Typography-aware in-place replacement matching background colors
  • Screenshot dropzone and clipboard image paste on Mac
  • Export translated images or extract editable text immediately

Voice & Conversational Speech

Natural acoustic recognition with low-latency speech synthesis.

Communicate across language barriers without rigid conversational pauses. Speech recognition feeds directly into on-device models and outputs crisp, native-sounding voice playback.

Core Capabilities

  • Low-latency streaming speech-to-text recognition
  • Natural neural voice synthesis with local dialect nuances
  • Hands-free turn-taking designed for face-to-face interaction
  • Reviewable transcript log with audio replay after sessions

Documents

Layout-Preserving PDF & Document Translation

Translate complex documents while retaining their structure where supported.

Translate documents while retaining their original structure where supported. The workflow can preserve elements such as columns, tables, formulas, typography, and embedded images in the translated document.

Core Capabilities

  • Retains fonts, columns, tables, and margins where supported
  • Preserves mathematical notation where the source allows
  • Maintains embedded images and vector graphics where possible
  • Side-by-side original and translated preview with dual export

On-Device Translation Models

Keep eligible translation workflows on device.

When a compatible on-device model is selected and installed, its translation runs locally without sending translation content to a cloud model provider. Availability and performance depend on the model, task, language, and device.

Core Capabilities

  • Run supported local models without a network connection once installed
  • Keep translation content on device for local model requests
  • Model and language availability varies by supported task and device
  • Avoid cloud network round trips for local model inference
