Testimonials
“I couldn’t stop being amazed!”
“With Textshine, no letter dances out of line. They are all where they should be. I can concentrate on the more important things and even under time pressure I have the certainty that far less slips through than before. Texts that have been previously edited with Textshine are so clean that I can read them faster and with a different eye. And texts that previously couldn't be proofread at all benefit the most from this addition.”
“We use Textshine as an additional proofreading layer because it consistently and reliably corrects inconsistent spellings of names, flags grammar and punctuation errors, and helps avoid typos. The handling with Word and track changes mode is simple, and even formal corrections like double spaces are detected with high accuracy.”
“For Nomos, Textshine has proven to be a reliable technology partner that successfully combines efficiency and quality and makes a key contribution to the development of modern publishing.”
“Textshine supports us with precise proofreading at the push of a button. This gives us valuable time in editing to devote entirely to fine-tuning the content.”

“Textshine played an important role in our training for almost 30 German federal agencies from the Federal Chancellery to the Press and Information Office of the Federal Government to the Federal Office for Information Security - here you can see how AI not only promises good things, but also delivers!”

“Textshine has changed our content creation process enormously. Large parts of the manual work have disappeared and the formal quality of our texts has improved massively. A solution we can no longer imagine our daily work without.”
“Textshine finds exactly the things that tend to slip through during 'content' reading. So I have the feeling: content good, everything else good too.”
“Textshine finds what even some professionals overlook under time pressure. The software is the previously missing and carefully implemented technical complement to the work of proofreaders — ideally it is also operated by them. Where no professional human proofreading is possible, at least Textshine should review it.”

“We use Textshine as an additional proofreading step that flags errors in grammar, punctuation and spelling without touching the style or content of the texts. Our final proofreading is then very quick and easy to handle, not least thanks to track changes. Especially for our extensive non-fiction titles, the tool is a great help!”
“Textshine finds what we sometimes overlook in editorial stress: typos and punctuation errors. This saves us time and allows us to focus entirely on the content.”

“I tested Textshine thoroughly with the trickiest texts and couldn't stop being amazed! Textshine is the most useful tool I've experienced in a long time.”

“Textshine prepares our manuscripts almost perfectly in terms of punctuation, spelling and grammar – our editors can focus entirely on the content. A tool we would not want to be without.”

“If you want to combine reliability and time savings under high work pressure, you should rely on Textshine.”
“As editorial director of an AI newsletter, I read a lot about new AI tools, test some of them myself, evaluate them, and then write about them. Many of these tools disappear from my screen afterwards — Textshine stayed. What particularly convinces me: Textshine makes no exaggerated promises. It focuses on formal corrections and keeps its hands off everything else. This clear focus sets it pleasantly apart from many other AI tools that try to be all-rounders. Textshine integrates smoothly and flexibly into my workflow, and even when I think a text is error-free — I'm usually surprised.”

“Textshine does exactly what you expect from a very good proofreading service. No surprises. Spectacularly unspectacular.”

Frequently Asked
Questions
Have a question that’s not covered here? Contact our .
Does Textshine replace journalistic proofreading?
In everyday editorial work, Textshine is intended as a supportive proofreading tool. It complements your existing expertise to create space for human creativity and editorial care. For editors, this means they no longer have to proofread for spelling errors and thus get more time for research and writing. For proofreaders, this means they can focus on more challenging aspects of their work: content review and stylistic revision, which are essential for high-quality publications.
How does Textshine differ from ChatGPT?
Unlike general purpose models like ChatGPT etc., Textshine is optimized for spelling and grammar correction and related processes. For you, this means: Stylistic and content interventions are kept to an absolute minimum, even less common subtleties and typographic conventions are considered, and you get integration into Word, InDesign, InCopy and your editorial systems, where changes are recorded and all formatting is preserved. It is also significantly faster, more secure (your data is not retained or reused!) and allows processing of texts of any length.
Does Textshine also provide writing assistance?
No. Textshine only corrects spelling, grammar, punctuation and typography. Textshine does not alter your wording and does not offer suggestions for content or stylistic improvements.
What happens with proper names, jargon and colloquial language?
Unlike other programs, Textshine is able to correct proper names, jargon and colloquial language like any other text. You don't have to manually enter these words into a dictionary.
What about data security?
Your texts are transmitted in encrypted form, processed only to complete your order, and irrevocably deleted immediately afterwards. We have a strong focus on trustworthiness and were awarded extensive funding as part of the AI Mission Austria of the Austrian federal government. More →
Which languages does Textshine proofread?
Textshine specialises in German-language texts and follows the conventions used in Germany, Austria and Switzerland. English texts are supported in a beta version.
Can Textshine follow our house rules?
Yes, with Textshine Business. In custom guidelines you define spellings, typographic conventions, protected terms and replacements. You can manage several guidelines self-service and pick the right one per project – also directly in the plugins and the browser extension.
Can Textshine proofread PDFs?
Textshine currently cannot proofread PDF files directly. Whenever possible, use the editable source file: if the PDF was created in InDesign or InCopy, export the document as IDML and have that file proofread. You then review the corrections directly in InDesign or InCopy.
