InstaText

InstaText does something Grammarly doesn't do as well: instead of correcting sentence by sentence, it rewrites your English text as a native speaker would write it, keeping your meaning while improving flow, naturalness and word choice.

InstaText is an AI-based text rewriting and improvement tool for English. Unlike traditional grammar checkers that flag errors one by one, InstaText rewrites the entire text holistically: it keeps the original meaning and ideas, but intervenes on sentence structure, vocabulary choice, naturalness and fluency to produce a result that reads like the work of an educated native speaker. The tool is particularly useful for those who write emails, articles, academic papers or business texts in English as a second language and want the final result to sound natural without relying on a human editor. The interface is minimal: you paste the text, press a button and receive the rewritten version, with the option to compare the original and accept or reject the changes. A Chrome extension, a Word plugin and integrations with other tools are available.

For professionals, academics and anyone writing in English as a second language who wants their texts to sound as natural as a native speaker's, without the manual work of revising sentence by sentence.

InstaText has no permanent free plan but offers a free trial to test the service. Paid plans start at $11.99 per month billed annually, with higher plans increasing monthly word limits you can process. It's more affordable than Grammarly Pro for a complementary positioning: where Grammarly corrects, InstaText rewrites.
