AI Writer
Starts a draft from a brief. Give it the subject, the audience and roughly how long it should be, and it returns structured prose you can edit rather than an empty page. Reach for it when you know what you want to say but not how to open.
All tools
Free writing tools, and which one to use when
Every tool on this site does one job properly rather than ten jobs badly. This page explains what each one is for, so you can go straight to the right one instead of guessing from a grid of names.

In short
- Every tool is grouped by the job it does — writing, checking, measuring, or keeping track of sources — so you can go straight to the one you need.
- Your plan decides how much, never what. Guest, free account and Pro all open every tool; the tier only sets how many words run through them.
- Several tools run entirely in your browser and cost nothing to use, however often you use them.
- Where a tool is unreliable, its own page says so — including the AI detector.
Writing and rewriting
Tools that produce text, or change text you already have. These are the ones that call a language model, so they are the ones your daily word allowance applies to.
Email Writer
Turns a few bullet points into an email you can actually send, in a register you choose. It is most useful for the awkward ones — chasing an unpaid invoice, turning something down politely, apologising without grovelling.
Social Media Post Generator
One brief, a native post for every platform you pick — X, Instagram, Facebook, LinkedIn, TikTok, YouTube, Threads, Pinterest, Reddit and WhatsApp — each inside its own character limit, with three hooks and a hashtag set you can toggle. Writes threads, carousels and short-video scripts too.
AI Content Generator
Eighteen kinds of writing in one workspace: essays, paragraphs, abstracts, outlines, conclusions, poems, slogans, business names, acronyms, meta descriptions, product copy, bios, cover letters and more. Pick what you are writing and it is written to that shape.
Headline & Title Generator
Writes the one line everything else depends on — a blog title, a title tag under 60 characters, a YouTube title, an email subject with its preview text, a 30-character ad headline, a product or essay title. Each set is counted against that surface’s own limit, scored, and shown in a real search result or inbox before you pick one.
Ask AI
A conversation rather than a single-shot tool. It reads PDF and Word files, so you can ask questions about a document instead of reading all of it again, and it will tell you when it does not know something rather than inventing an answer.
Paraphraser
Says the same thing in different words, at a strength you set. Useful when a sentence is correct but clumsy, and when you have stayed too close to a source and need genuinely your own phrasing.
AI Rewriter
Rewrites what you already have, in different words and the same meaning, with your names and numbers left alone. It opens the Paraphraser’s workspace on the same free allowance, and has a page for each job — sentence, paragraph, essay, article or blog post — with a real before-and-after on every one.
AI Humanizer
Rewrites machine-flat prose so it reads like a person wrote it: sentence lengths vary, stock openers go, and the vocabulary comes back down to ordinary words. It will not promise to defeat AI detectors, and its page explains at length why any tool promising that is misleading you. Every rewrite now comes back with a receipt listing which names, numbers and quoted phrases were checked and preserved.
Tone Changer
The same content in a different register — formal, friendly, confident, direct. It is a rarer tool than it sounds: of twenty-one competing sites we catalogued, only three have one at all.
Summarizer
Reduces long text to its actual argument at a length you choose. It keeps the claims and the qualifications, and drops the padding, which is the opposite of what a word-count-based summary does.
Translator
Translation across more than a hundred languages, with a formal or informal register and the option to keep names, brands and technical terms untranslated so they survive the trip.
Checking
Tools that look at text you already have and tell you what is wrong with it, or what changed.
Grammar Checker
Spelling, grammar and punctuation, with each suggestion explained so you can disagree with it. A checker that cannot say why it wants a change is asking you to trust it blindly, which is how good sentences get flattened.
AI Detector
Estimates whether text reads as machine-written, and shows the evidence behind the number instead of a bare percentage. It is also candid about its own limits: no detector is accurate enough to act on by itself, and false positives fall hardest on people writing in a second language.
Text Compare
Shows exactly what changed between two versions — by word, character or line, including blocks that moved rather than changed. It makes no network request at all: the text never leaves your browser, and a test fails the build if that ever stops being true.
Measuring
Tools that count, score and analyse. These run in your browser or on plain arithmetic, so they cost nothing to serve and nothing to use.
Word Counter
Much larger than its name suggests. Alongside words, characters, sentences and paragraphs it gives six readability formulas, keyword density with stopwords filtered out, reading and speaking time, and the character limits for 35 platforms from X to a meta description.
Character Counter
Characters with spaces and without, side by side, then checked against 35 platform limits at once — and it tells you which of those numbers the platform actually publishes and which are conventions somebody invented. Pick a platform and it shows where your text gets cut, then trims it there at a whole word.
Readability Checker
Six formulas — Flesch Reading Ease, Flesch–Kincaid, Gunning Fog, SMOG, Coleman–Liau and ARI — and then the part a score cannot do: every sentence graded on its own and ranked hardest first, with the likely passives and the three-syllable words named. Click a sentence and the cursor lands on it.
Words to Pages
Everything else in this category multiplies by 250, which is a Courier New number. This lays your text out in an off-screen box the exact size of your page, in your font at your size and spacing, and counts — then shows the arithmetic. Seven fonts, five paper sizes, and it works backwards too.
Case Converter
Fourteen conversions previewed at once, so you pick by looking. And title case in all four style guides — Chicago, AP, APA and MLA — side by side, with the words they disagree about marked, because there is no single correct title case.
Sentence Counter
Counts sentences, then lists every one of them with its length and flags the long ones. It knows that Dr., e.g., U.S. and 3.5 do not end a sentence, which is where most sentence counters go wrong, and it finds the repeated openings you cannot hear in your own draft.
Word Frequency Counter
How often every word and every two to five-word phrase appears, with density. The stop word list is shown in full and you can edit it, and clicking any entry collects every sentence it appears in — which is the part that actually changes a draft.
Symbol Counter
Counts symbols four ways, because a browser form, a database, an SMS gateway and a reader all count differently and all four are right. It also finds the invisible characters that arrive with pasted text, and works out what a message costs to send.
SEO Keyword Tool
Pulls the real keywords out of a page or a block of text, with density, weighting and where each term actually appears — title, first heading, opening paragraph, meta description. It prints no search-volume figures, because we have no licensed source for them and will not invent numbers.
Sources and notes
Tools for the work around the writing: citing what you read, and keeping what you wrote.
Citation Generator
Paste a DOI, ISBN, PubMed or arXiv ID, a URL or just a title, and get a finished reference and in-text citation in any of 10,861 styles, exportable to Word. Nothing is gated and there is no sign-up, which is deliberate: students are the people least able to pay for this.
Notebook
A private place to write and keep notes, with optional end-to-end encrypted sync so they survive a cleared browser and follow you to another device. It imports Word, PDF, Markdown and plain text, keeping headings, lists and tables intact.

What it costs
Nothing, to start. You can use every tool on this page without an account, and the tools that run in your browser — Text Compare, the Word Counter, the Citation Generator and the Notebook — have no usage limit at all, because they cost us nothing to serve.
The tools that call a language model do cost us money on every run, so they draw on a daily word allowance. Making a free account raises it; Pro raises it a great deal further. What the plan never changes is which tools you can open: every plan includes every tool, and every tool released in future is included in the plan you already have, at no extra cost.
Your writing is not stored. Text you paste in is used to produce the result and is not kept afterwards. We record a word count and a checksum so allowances work — not the text. The privacy policy sets out exactly what is retained.
Questions people ask before they start
Do I need an account?
No. Every tool works signed out, on a smaller daily allowance. An account is free and raises it, and is the only way to sync Notebook or keep drafts across devices.
Are these tools actually free, or free until the second paragraph?
Actually free, with an honest ceiling. Nothing is hidden behind a paywall mid-result: you are told the limit up front on the pricing page and again if you reach it.
Will anything here get me through an AI detector?
We will not claim that, and you should be careful of any tool that does. The humanizer improves how writing reads; whether some future detector flags it is not something anyone can promise. Our own position on academic use is written down rather than implied.
Which tool is best for students?
The Citation Generator and the Word Counter are the two most used, and both are free without limit. The AI Detector is worth reading about before relying on it, particularly if English is not your first language.
Is there more written about how this works?
Yes — the blog goes into the reasoning at length: how AI detectors work, what an accuracy claim like “99%” actually means, why human writing gets flagged, what to do if you are wrongly accused, and the nine edits behind the humanizer. Each tool page also explains its own method and its own limits.
