Bioedit Ltd is an online English editing and proofreading service for scientists in the fields of life and medicine. Their services are used to check and correct English usage, grammar, punctuation and sentence structure in manuscripts prior to submission for publication in academic journals; they ensure a faithful conveyance of ideas without altering the meaning of the original text. Bioedit.co.uk was incorporated in 2001 and is located close to the University of Manchester in Stockport, UK.

 Bioedit provides 3 levels of editing for their clients. Level one is Proofreading, which is done by a resident expert in the English language. This level applies the standard rules of English grammar and spelling correction to the text without rearranging or rewriting it to make it more understandable. Level 2 is Comprehensive Editing which is done by one of the scientific editors. This level incorporates all the proofreading qualities of level one but adds additional services to improve the presentation of the work and increase its clarity. Level 3 is Comprehensive Editing Plus. This level adds a third layer to the process by including everything from level one and two as well as a thorough reading by a member of the editorial staff, allowing the manuscript to be published directly without any further editorial input.

Turnaround time is determined by the urgency of the request with an additional cost per word for faster service. The Regular service has a usual turnaround time of 7 days; the Express service is 4 days; and the Super Express service is within 48 hours. All costs are calculated on a per word basis with no hidden additional fees.
