This site provides no-cost editing of short, complete documents (approximately 250 words), such as an abstract, reviewer comments, response to reviewers, or other short communications.
I have started a crowdfunding project that will allow me to provide free or discounted editing services for researchers from some countries. To check if you are eligible and register your interest please fill out the form on this page: https://www.scienceeditorium.com/crowdunding-campaign/
If you would like to support our campaign you can visit the funding page https://igg.me/at/scienceeditorium/x/16702788 or share it with your network of researchers.
