AI translation and proofreading with Sleek Translator
Sleek Translator is an online tool for translating text and correcting spelling, grammar and punctuation. Choose an AI model and work with your own API keys in a focused interface.
Translate text into another language
Type or paste your text, choose the source and target languages, and translate. The app supports languages including English, Russian, Armenian, French, Spanish and German. You can select the source language manually or use automatic detection.
Proofread and adjust your writing
Proofreading checks spelling, grammar and punctuation while aiming to preserve your meaning and style. Translation settings let you choose a tone and language level. You can request a new version or explore word alternatives when using a personal API key.
Choose your AI provider
Connect your own key for a supported provider, such as OpenAI, Google Gemini, Anthropic Claude or DeepSeek, and choose a model. Availability depends on your provider account. Provider API charges are paid separately; the app shows estimated usage costs.
How to get started
- Open the translator and add your API key in settings.
- Select a model and your language pair.
- Paste text and choose translation or proofreading.
- Review the result before using it.
Privacy and limitations
With a personal API key, text is sent directly from your browser to the selected AI provider. Keys can be kept in page memory or saved in this browser, depending on your settings. Provider data policies vary. AI can change meaning or miss errors, so check important text yourself.
Translation requires an internet connection and JavaScript. Demo access depends on whether the server demo is configured; personal API keys provide access independently.
