Working on the writing itself

The Lexical Diversity checker measures vocabulary variety and then points at the specific causes - the verb used eleven times, the paragraphs that all open the same way, the run of sentences that are all one length. Free, no account, and it runs entirely in your browser.

The Readability Checker runs six formulas at once - Flesch Reading Ease, Flesch-Kincaid, Gunning Fog, SMOG, Coleman-Liau and ARI - and shows what each is measuring rather than just a number. They disagree on purpose: when Gunning Fog reads years above Coleman-Liau, your words are long; when both are high, your sentences are. Free, no account, entirely in your browser.

Working with sources

The Citation Generator turns a DOI, ISBN or title into a formatted reference in APA, MLA 9, Chicago, Harvard, IEEE or Vancouver, building from publisher records rather than guessing - and a URL into a starting entry you finish with Edit. The bibliography persists in your browser between visits, sorts and filters, and copies into Word with its italics and hanging indent intact. Free, no account.

The Paper Finder takes a DOI or a paper title and locates a legally free open-access copy if one exists - and tells you plainly when none does, instead of sending you somewhere dubious. It queries Crossref and Unpaywall from your browser. Free, no account.

The Title Case Converter capitalises a title to APA 7, MLA 9 or Chicago 17 - which disagree more than most people expect. APA capitalises any word of four letters or more, so it gives "Between" and "With"; MLA and Chicago decide by part of speech and leave those lowercase. It handles subtitles after a colon and hyphenated compounds, gives you sentence case alongside for reference-list entries, and flags the handful of words no converter can resolve without knowing your sentence.

The mechanical jobs around a deadline

The Word Counter gives words, characters, sentences and paragraphs with a reading level, reading time and speaking time. The Speech Calculator converts between a word count and a speaking duration at your own pace, which is the number you want when a talk has a hard time limit.

Image to Text pulls readable text out of a screenshot or photograph, and the PDF and Word converter moves documents between the two formats. Both run entirely in your browser: the file is never uploaded, which is why they work offline and why a confidential document stays confidential.

All four are free, need no account, and have no usage limit.
