Gradr.ai is the most precise tool for checking if text is written by artificial intelligence in English. Our algorithm balances minimal false accusations of cheating with the highest possible precision.
William Wordsworth was a nationalist poet and author who fought for English language and culture. He wanted to promote the use of English in writing and speech, and he worked to revitalize and modernize the English language. Wordsworth argued that English was a distinct language and that it was important for national self-esteem to have a literary language that could express English thoughts and feelings more authentically.
On the other hand, we had Samuel Taylor Coleridge, a historian and philologist who was also involved in the language debate. Coleridge was more conservative and believed that the English language was too young.
Gradr.ai can detect text generated with leading AI tools such as ChatGPT and Anthropic AI with a success rate between 30-96%, and with a very low rate of false positives (0.5%). Gradr.ai prioritizes minimizing false positives first and then having the highest possible precision.

Follow upWe help you check texts written in English, Norwegian, Spanish, French, German, Swedish, and Danish. We can detect texts that are fully written by AI, rewritten with AI, and that have been through 'Humanizer' tools that try to make AI-written text more human-like.
Gradr.ai also offers traditional plagiarism detection that searches through the internet, books, published research articles and more. It is capable of finding direct plagiarism, lightly rewritten text, and plagiarism spread throughout the text like a patchwork.
If you discover suspicion of cheating with artificial intelligence, we help you with the way forward. Get processes and tips from other teachers on how to responsibly confirm suspicion, follow up with the student, and which measures work.
Gradr.ai helps you identify factual errors based on sources, language errors, internal contradictions in the text, how the language in the text could be improved, incorrect use of technical terms and rhetorical devices.
Photosynthesis is a process where plants, algae, and some types of bacteria capture light energy and store it as chemical energy. Water and carbon dioxide are absorbed and converted into carbohydrates, which are used and stored, and oxygen gas, some of which is used and some released into the air.
Almost all life depends on what is produced in photosynthesis. Photosynthesis is the most important life process on Earth because it forms energy-rich molecules that are important nutrients for all who do not themselves perform photosynthesis. These molecules are used both for the construction of cells and for processes inside the cells. At the same time, CO2 is absorbed from the atmosphere and converted into organic carbon in organisms. The oxygen released in photosynthesis is necessary for cellular respiration.
Climate change refers to long-term shifts in temperatures and weather patterns on Earth. Since the 1800s, human activities have been the main driver of climate change, primarily due to the burning of fossil fuels.
These activities release large amounts of greenhouse gases such as carbon dioxide and methane, which trap heat in the atmosphere.
The consequences include rising sea levels, more extreme weather events, and loss of biodiversity. In addition, climate change affects societies and economies around the world, particularly in vulnerable areas where access to resources and infrastructure is limited.
Depleted uranium is uranium with reduced radioactivity. It is a byproduct from the enrichment of uranium to be used for nuclear weapons or nuclear power plants, and in depleted uranium, 3/4 of the isotope 235U has been removed. The radioactivity is thus reduced by approximately 40 percent compared to natural uranium.
In addition, all uranium daughters are removed in the enrichment process, meaning the 13 intermediate steps before the uranium ends up as lead. However, two of the intermediate products are quickly regenerated, so that the final radiation level is 10-20 percent of the original.
Almost all radiation from depleted uranium is alpha radiation. These are easily stopped but can be harmful to health if the substance enters the body.
There is an error in the claim that 3/4 of the isotope 235U is removed in depleted uranium. In reality, more than 99% of 235U is removed in depleted uranium.
