Isaac Editor

Isaac is a browser based writing workspace built for academic work, combining a document editor, an AI assistant and a literature search tool in one app. It aims to cover the stages of a paper from reading sources to drafting and citing, so researchers and students do not move between separate tools. The editor offers AI supported writing, including autocomplete, paraphrasing and summarizing, plus a chat assistant tuned for academic writing. Users can search academic literature and read results inside the app, upload their own papers and ask questions about them, and keep documents in a reference list that sits beside the text. Automated functions are provided to speed up literature reviews, with more described as coming. The interface is available in 16 languages. The vendor states that Isaac does not produce finished papers at the click of a button, that data is hosted on servers in the EU and complies with GDPR, and that it is built by a small team of German and US based engineers with an academic background. It is currently available on desktop only, not on mobile. Pricing is published in USD. The Free plan costs $0 and includes 10 daily AI tokens, 100 MB of file storage, AI assisted writing, document chat and literature search.

Pro is listed at $16.66 per month billed annually at $200, and adds unlimited AI and chat, unlimited storage, premium AI models and premium support.
