Transor — Tone-Aware Translation & AI Language Chat (70+ Languages)

Transor is a tone-aware translator and AI language coach for 70+ languages. Choose Polite, Casual, Professional, or 30+ styles; ask follow-ups; learn why phrasing works; and use a lightweight offline mode when you’re not connected. Built with a client-first, no-server architecture for privacy and near-zero ops.

Why Transor

Context & tone, not just words — Captures intent, register, and nuance.
70+ languages — Designed for both major and long-tail languages (including Thai).
30+ tone styles — Match your voice: business, friendly, academic, playful, poetic, and more.
AI Language Chat — Practice with role-based personas (tutor, business partner, travel companion).
Offline fallback — On-device dictionary for essential lookups without connectivity.
No-server, privacy-first — Direct provider calls from the app; no central backend to breach.

What it does

Context-aware translation powered by Google Gemini 2.5 Flash
Smart conversations: follow-ups, alternatives, grammar notes, usage examples
Learning loops: focused practice sessions (up to 10 turns) that reinforce concepts
Real-time adaptation: adjusts for formality, slang vs. standard, and emotional tone
Gender-aware phrasing (e.g., Thai polite particles ครับ/ค่ะ, Spanish agreement, Arabic verb gender)
Clean, fast UI with dark/light themes; start free, upgrade for unlimited AI

How it’s built

Framework: React Native (Expo) • Language: TypeScript
AI Engine: Google Gemini 2.5 Flash
Prompting: Task-specific, tone-aware prompts with conversation memory
Subscriptions: RevenueCat (cross-platform IAP & management)
Security: Encrypted on-device storage for keys and user data
Architecture: No-server, client-first (provider-direct online; lightweight offline dictionary)

Challenges & solutions

App review & offline requirements: Added an offline dictionary fallback to ensure essential functionality without keys/connectivity.
On-device translation path: Deferred native ML toolchain; shipped a lightweight dictionary now, with ML Kit planned for richer offline sentences.
Human-quality outputs: Filters and validations reduce robotic phrasing, preserve context, and enforce tone accuracy.

Results we’re proud of

30+ tone styles that map to real use cases
Role-based coaching that teaches, not just translates
Context persistence across turns for more natural conversations
Long-tail language support (including Thai) with parity features
Client-first design → predictable costs, stronger privacy

What we learned

Context and tone drive usefulness more than literal word swap.
Conversation and explanation support better retention than one-shot outputs.
Guardrails (validation, artifact cleanup) are essential for professional results.
Designing for long-tail languages influences UX, tone presets, and data minimization.
Offline capability improves reliability and clears app-store expectations.

Roadmap

Android launch (Google Play)
Voice translation (evaluating ElevenLabs)
More personas (legal, medical, technical)
Scenario packs (interviews, travel, negotiations)
Progress & drills (adaptive vocab and practice)
Multimodal OCR for images/docs/screenshots
Stronger offline with ML Kit—sentence-level on-device
Maintain no-server architecture while scaling users
