What is Isaac?
Isaac is an AI-powered academic writing and research workspace for researchers and students. Isaac combines writing, literature discovery, document questions, and reference organization in one app. The integrated assistant is designed specifically for academic writing, giving users research-focused support alongside the text and documents they are working with.
Isaac was developed by a small team of German and US-based engineers with backgrounds in academia. The website presents Isaac as a way to augment research workflows, not as a system designed to output complete papers with a single click. That distinction frames the product as an assistant for ongoing academic work.
What Isaac can do
Isaac brings several stages of academic work into a shared workspace. Isaac supports writing and editing, finding relevant papers, asking questions about documents, and maintaining references. Automated functions also support literature review workflows, while the paid plan listings add capabilities such as first-draft generation and access to premium AI models.
- Isaac provides autocomplete, paraphrasing, and summarizing for academic writing.
- Isaac searches and displays relevant academic literature within the app.
- Isaac answers questions about uploaded papers.
- Isaac saves and organizes documents in a reference list within the editor.
- Isaac provides automated functions for literature reviews.
- Isaac lists first-draft generation on paid plans.
How Isaac works
Isaac is a web application that is currently available only on desktop. Within the workspace, users can write with AI assistance, search and read academic literature, and upload papers for document-based questions. Saved documents remain accessible through the reference list inside the editor, connecting source organization with the writing workflow.
Isaac supports use in 16 languages. The website also states that user data is hosted on GDPR-compliant servers in the EU. Access can begin through the free plan without providing a credit card, while paid plans provide additional allowances and features listed in the pricing table.
