slAItor - Your AI translation assistant | Product Hunt

Powered by AI

slAItor combines recent advances in AI (GPT) with more standard machine translation techniques. A new kind of system that does much more than just translating.


slAItor can explain a translation step-by-step and with details. You can use this unique functionality to learn or improve your understanding of a language.

Spot and explain errors

Thanks to the checker mode, you can provide your own translations to slAItor: It will spot, explain, and correct the errors.

Translation alternatives

slAItor's paraphraser and style calibrator are powerful tools that can adapt the translations to numerous contexts.

AI + translation technologies = slAItor

We combined the recent advances in AI and large language models with state-of-the-art translation technologies.

  • slAItor prepares your query to make it easy to process by the AI engine. It includes some normalization, tokenization, and splitting of your text. Then, everything is packed into a "prompt" to be sent to the AI engine. This step relies on several open source projects such as preprocess, sacremoses, and Pytorch.

  • For now, slAItor mainly exploits models from the GPT family by OpenAI. We keep exploring alternatives, including the development of our own model. For more information about these technologies, you can read my blog posts about translating with ChatGPT and translating with GPT-3.

  • This step checks and formats the answer. We use again several open source projects.

  • We continuously monitor slAItor's performance using in-house evaluation datasets as well as public benchmarks. We rely on a state-of-the-art automatic evaluation metric, COMET, and human evaluators.

Frequently Asked Questions

  • "credit" is the unit slAItor uses to simplify the evaluation of the translation cost.

    The cost in credits is automatically computed given the length of your text and the options you selected. This costs is indicated just below the text area where you enter your text.

    Translating 1,000 characters costs 1 credits. This costs is tripled to 3 credits for the step-by-step translations and in the checker mode. The minimum cost of a query is 0.1 credit.

    For example, with our subscription, you can translate up to 800,000 characters a month.

    Credits are automatically debited from your account as soon as you press "translate" (or "Check" in the checker mode). If you stop the translation before it finishes, credits won't be refunded.

    If you need more credits, in a near future we will propose packs of credits that you can buy separately at anytime.

  • We can tell you that it is a mix between standard machine translation technologies and state-of-the-art large language models from the GPT family.
