Writing tools for the AI era, running entirely in your browser

Writing has picked up a new set of chores. Text goes into AI models that bill by the token, so length suddenly has a price. Drafts come back too long, so summarising is a daily job. And everything still has to be readable by an actual human at the end. The tools here handle those three jobs, locally, with nothing sent to any server.

The AI token counter runs the same BPE tokenizers the big models use and tells you exactly what a prompt weighs before you pay for it, with a cost estimator you can point at whatever today's prices happen to be. It is the quickest way to understand why your bill never quite matches your word count.

The text summarizer is deliberately not an AI model. It is a transparent algorithm that scores your own sentences and keeps the strongest ones, which means it can never invent a fact that was not in the original. For meeting notes, long articles and reports you were sent at 5pm, that guarantee matters more than eloquence.

The readability checker closes the loop with Flesch, Flesch-Kincaid, Gunning Fog and SMOG scores plus the sentences that are dragging them down. Pair it with the word counter while editing and with the SEO content analyzer before publishing.

There is also a dictionary lookup for definitions, pronunciation, synonyms and antonyms, which sends only the word you type and nothing else.

Everything in this category works offline once the page loads, needs no account, and never sees your text leave the tab. If you are pasting in unreleased copy or a client's document, that is not a nice-to-have, it is the whole point.
