This section addresses a number of common questions. If your question is not here just drop us a line.
Writefull uses large language databases to search for the frequency of chunks of text. The databases used are Google Books, Google Scholar, Google News, and Google Web. All you need to do is select a chunk of text (in whatever writing tool you use), activate the Writefull popover, and request the information you need. Check out the tutorial for more information.
Yes you do, as Writefull uses a database which is stored on the Internet.
Just click here and follow the steps.
At Writefull we take your privacy seriously. Writefull will cache some searches, but these won’t be associated to your username. They will only be used for speeding up future searches.
The way Google Books organises its data is in ‘groups’ of tokens, ranging from 1 to 5 tokens each. So when searching the database for a chunk, you cannot search for more than 5 tokens at once. Note that tokens also include symbols such as the apostrophe (‘) and hyphen (-); so don’t count words only! A selection of ‘this isn’t your well-being’ contains 5 words, but 8 tokens. This is a limitation of Google Books, and is exactly why we also provide Web searches.
