What students say
“The tool is great for writing varied sentences and getting inspiration on how to express certain ideas more concisely.”
Büsra
“We're currently working on our bachelor's theses and discovered you through TikTok — people are raving about you there :) You're a lifesaver 🙏🏼”
Yannic
“I used the tool for my bachelor's thesis and am still using it. It helps by taking over the scanning of sources and making the writing flow easier, so you don't have to read every document from start to finish yourself.”

FAQ
Frequently Asked Questions
Questions about fastwrite? Here are some of the most frequently asked ones to help you get started.
Which devices is fastwrite available for?
fastwrite is available for macOS & Windows, and as a web version for iPad, Chromebook, and all other devices.
Which AI models does fastwrite use behind the scenes?
fastwrite is built on the latest large language models, which we have optimized specifically for academic writing. We combine these models with advanced document analysis developed specifically for academic texts.
How does fastwrite work?
The add-in analyzes your uploaded documents and understands their content. As you write, it suggests fitting phrasings, content, and citations. If no sensible suggestion is possible based on your own literature or our paper database, you get a generic suggestion without a reference.
What happens to my data?
Your documents are stored securely on our servers and analyzed exclusively for your personal use.
Is there a risk of plagiarism when I use fastwrite?
fastwrite was built to avoid plagiarism. The tool automatically detects when you use content from your sources and inserts a reference right away. That way you make sure every adopted idea and passage is properly attributed. The AI also helps you phrase content in your own words instead of copying it directly. AI use must be disclosed according to your university's guidelines.
Is fastwrite suitable for every field of study?
Yes — the tool automatically adapts to your literature, regardless of your discipline.

COMPARISON
fastwrite vs. ChatGPT: why a specialized tool beats a general chatbot
ChatGPT is a great generalist — but for essays and theses it lacks real sources, page references and Word integration. An honest comparison, including where ChatGPT is the better tool.
