Rewrite anything in your voice.
Fairywren measures the way you write - the rhythm of your sentences, the habits of your punctuation, the peculiar turn of your phrase - and uses that measurement to rewrite anything you paste in. Your voice on the page; not the AI model's.

LinkedIn is, at its core, a professional social network. The overlap between several things that used to live separately — your CV, your contacts book, your industry reputation, your job search — is precisely what makes it useful, and occasionally insufferable.
People use it for six main purposes.
The first is the profile itself: an online record of jobs held, skills claimed, education completed, projects undertaken, and achievements that seemed worth mentioning at the time. The second is connection — colleagues, recruiters, clients, founders, investors, and anyone else whose professional acquaintance might one day prove convenient.

Frequently asked Questions
The questions readers tend to put to us, with the replies.
How is this different from ChatGPT?
ChatGPT can attempt to rewrite content to look less like AI, but it will leave a great many of its tells behind. It also has no measurement of what your writing should look like — only a vague gesture at one. Fairywren measures your prose specifically, then rewrites against that measurement.
Do you train on my writing?
No. Your samples and rewrites travel to Anthropic's API; per Anthropic's commercial terms, those inputs are not used to train Anthropic models. Your fingerprint stays in your account.
How secure is my data?
We dont store any credentials for login or any social media integratin credentials. We also dont store any data related to billing, that is all stored in Stripe.Your content is encrypted in transit and at rest.
Does this integrate with LinkedIn?
You can use Fairywren to rewrite your content, but there is no direct integration with LinkedIn. LinkedIn does not allow services to manage content directly in that way, it would be a breach of LinkedIn terms and put your account at risk of being terminated..
