ContextAI Translate is a privacy-first AI translation web app that uses advanced large-language models to provide conversational translation, side-by-side text comparison, summaries, file uploads, and more. It is developed by a small product-focused company, Necta LLC.
Yes — the app is free to try with built-in starter tokens. You only need to purchase tokens if you want extended or high-volume usage. The product is pay-for-usage, not subscription-based.
No. We intentionally avoid collecting personal identifiers, emails, IP-based location, or tracking analytics. Login is implemented using an anonymous ID-string system so you can use the service without revealing identity.
Because we do not want to collect any personal information. A random ID string allows persistent token balance and user isolation without linking to a real person. This keeps the product safe, anonymous, and compliant with strict privacy principles.
We currently support: PDF documents, Docx documents, Images (PNG / JPG / WebP), and Plain text files. Future formats are planned based on beta feedback.
It excels at conversation translation. Unlike traditional translators, ContextAI remembers context across paragraphs and responds naturally, making it ideal for chat screenshots, multilingual threads, learning, and forum discussions.
Accuracy depends on model behavior and complexity of text, but generally very strong for natural speech and long-form context. Since AI translation is probabilistic, for critical legal/medical use, we recommend reviewing results manually.
Yes. The app has built-in side-by-side diff mode so you can read the original text and translation simultaneously — especially useful for learning languages or reviewing AI nuance.
Each translation request consumes tokens based on input and output length. Tokens are stored on your anonymous ID, so you won't lose them, even across devices.
Current official pricing:
• $5 → 1,000,000 tokens
• $10 → 2,200,000 tokens
• $20 → 5,500,000 tokens
• $50 → 15,000,000 tokens
No, tokens do not expire for now. Since this is still an early beta product, future token policy may evolve based on operational cost and user scale, but your purchased tokens will remain valid.
Translations are processed on secure servers using large-language translation models. No personal data is attached to requests, and results are not stored permanently unless session history is enabled by the user.
Yes — anytime. We do not store long-term logs tied to identity. Temporary history exists only for UX session continuity, and you can clear it instantly within the app.
