Measuring and checking writing
Word & character counter
The counter gives two numbers: words, counted as runs of text separated by whitespace, and characters, counted as every space, line break and symbol in the box. Its limit is that characters are UTF-16 code units, so one emoji counts as 2 and a joined family emoji as 8 — plan message lengths with that in mind. If your figure disagrees with a word processor, the reasons are set out in how word counts differ.
Flesch Reading Ease checker
The reading ease checker applies the standard Flesch formula to your sentence, word and syllable counts and prints one score. The limit is the syllable count: it is estimated by counting vowel groups, which makes "beautiful" four syllables and "1,000" one. Expect a few points' difference from dictionary-based software, more in text full of numbers or acronyms, and use it only on English.
Extractive text summarizer
The summarizer scores every sentence by how often its words appear elsewhere in the text, then copies the three highest-scoring sentences out in their original order. It writes nothing of its own, so it cannot invent a fact — but it also cannot keep context. Opening sentences that introduce a person score badly and get dropped, which leaves pronouns stranded. Always read the result against the source.
Word mood analyzer
The mood analyzer counts how many of 14 positive and 15 negative English words appear in your text and says which side is larger. That is its whole method, and its limit follows directly: it scores "the food was not good" as positive, because it has no idea what "not" does. Use it to prompt a reread of your own wording, never to judge someone else's.
Preparing files, prompts and plans
AI Prompt Builder
The prompt builder takes a task type, a topic, an audience, a tone and any constraints, and assembles them into a written prompt you can copy into whichever assistant you use. It fills a template; it does not contact an AI model and does not produce the article, image or lesson itself. Editing the result before you send it is expected, not optional.
Image compressor
The compressor re-encodes images in your browser, with a quality setting, an optional maximum width and a choice of output format, and can zip a batch for download. The limit is that JPEG and WebP re-encoding is lossy and one-way: detail removed cannot be restored, and the resulting file size is approximate rather than exact. Keep your originals, and read image quality versus file size before choosing a setting.
DOCX text to PDF
This converter pulls the raw text out of a .docx file and lays it into an A4 PDF in a single 12-point font. Call it what it is: a text extractor. Headings, bold, tables, images, headers, footers and page breaks are all discarded, and it covers Western Latin characters only — for other writing systems, or for a PDF that must look like the original, export from your word processor instead.
Content calendar generator
The calendar generator builds an editable posting grid from a start date, a date range, your chosen platforms and your own list of content themes. Its posting times are picked at random between 8am and 10pm, so they are placeholders to replace, not advice about when your audience is online. It does not connect to any account or publish anything.
Which one to reach for
A practical order: draft your text, measure it with the counter if a limit applies, run the reading ease check to find sentences that have grown too long, and use the summarizer only when you need to see which sentences repeat the topic. Then prepare the image, and plan the posting date last.
None of these tools sends your text or files to a server, and none of them calls an AI service. They are small, fixed rules, which is why each page states its method in full. If a result looks wrong, the method page explains how we check and correct these tools: calculation methods and corrections. Other categories: math calculators, converters and guides.
