slAItor vs Behnevis

slAItor is an online translation assistant built around large language models from the GPT family, combined with standard machine translation pipelines. Instead of returning a single translated string, it is designed for people who want more context around a translation: explanations, alternatives, style adjustments, and error checking.

The product targets language learners, translators, and professionals who need more than a quick paste-and-go result. Benjamin Marie, who holds a Ph.D. in machine translation and has spent more than a decade in MT research, built slAItor to explore what becomes possible when GPT-style models sit at the center of a translation workflow.

slAItor supports 28 language pairs across Chinese, English, French, German, Italian, Japanese, Portuguese, and Spanish. The site is upfront that raw translation quality can trail established systems in some cases, but positions itself on price and on features like step-by-step explanations, paraphrasing, and a checker mode that reviews your own drafts.

Behnevis is an online Persian writing tool that turns Pinglish or Finglish (Persian typed with Latin letters) into standard Persian script. You type in the editor, and the site converts words as you go. It has been running since 2009 and targets Persian speakers who prefer typing with an English keyboard.

The main site offers an in-place editor plus speech-to-text that supports Persian and more than 100 other languages. You can click any converted word to fix its spelling, and Behnevis remembers that correction for later. The legacy two-part editor remains available for free with no usage limits.

Paid plans unlock unlimited in-place editing, speech-to-text, an ad-free experience, and a Microsoft Word add-on for Windows. Behnevis also links to custom OpenAI GPT chatbots for Persian conversation practice.
