input: My name is John Smith and my email is john@acme.com. I always write short punchy sentences.

ghosted: My name is [Person A] and my email is [Email 1]. The author tends to communicate through concise, direct statements that carry considerable weight.

Three layers of anonymization

Use each layer independently or chain them together for maximum protection.

PII Ghost

Detects and removes names, emails, phone numbers, addresses, and IDs. Powered by Microsoft Presidio — runs locally, your data never leaves the server.

Style Ghost unique

AI rewrites your text with a completely different writing style. Sentence length, vocabulary, tone, structure — all changed. Your authorship becomes untraceable.

Document Ghost coming soon

Strip hidden metadata from files — EXIF data from photos, author info from documents, revision history from PDFs.

What is Haamu.ai?

Common questions about text anonymization and writing style privacy.

What is Haamu.ai? +
Haamu.ai is an AI-powered text anonymization tool that removes personal data (names, emails, phone numbers, addresses) and disguises your writing style so your authorship cannot be traced. It combines PII detection, stylometric anonymization, and metadata stripping in one tool.
How does writing style anonymization work? +
Style Ghost uses AI to rewrite your text with a completely different writing fingerprint. It changes sentence length, vocabulary, tone, and structure while preserving the original meaning. This prevents stylometric analysis from linking the text back to you.
Is Haamu.ai free to use? +
Yes. Haamu.ai is currently in open beta and completely free to use — 2,500 words per day, no signup required. Paid plans (Student and Pro) with higher limits are coming soon.
Is my data safe with Haamu.ai? +
Haamu.ai processes text in memory only and does not store, log, or retain any submitted text. PII detection runs locally on our server using Microsoft Presidio. The service is hosted in Helsinki, Finland on European infrastructure.
