Aithor is an AI writing and research assistant for academic work, founded in 2023 and based in Tallinn, Estonia, with Dmitry Afonov as CEO; the product focuses on essays, literature reviews, case studies, and research papers rather than general-purpose copywriting.
The editor draws from a claimed 10 million-plus academic sources with PDFs attached, generates citations automatically, and suggests structure while users write, alongside a rewriter and paraphrase tool the company added in January 2026 to help students revise drafted text while keeping the original meaning intact. Aithor markets itself around producing writing that reads as human-authored.
Aithor is built for students and early-career researchers who need help structuring and sourcing academic writing rather than professionals drafting business content. A free plan gives access to the source database and basic writing help; the paid plan runs $24.99 a month, dropping to $16.99 on a quarterly plan and $8.33 a month billed annually.
