While most writing apps scan your texts to feed AI models, we built a platform where the server doesn't see — and never will see — what you write.
Most writing platforms include clauses that allow the use of your content for 'product improvement' — which almost always means training AI models with what you wrote.
Researchers have already found fragments of unpublished books, in-progress screenplays, and confidential articles inside datasets used to train LLMs.
Features like smart autocomplete, writing suggestions, and contextual correction frequently send your text to external servers — without encryption, without explicit consent.
Documents stored in cloud without E2EE can be accessed by the provider's employees, hackers, or governments via court orders. Your sources depend on your tool.
What if there was an editor where the server simply can't read anything? Where every word is encrypted in your browser before touching the network? Where not even Writtt itself has access to what you write? That editor exists.
Your ideas are not our training product. Every word you type is shielded with AES-256-GCM in your own browser. What reaches our servers is pure cryptographic noise — no meaning, no value, no use for any AI. We don't read. We don't train. We don't touch. The rule is simple: not even we can read what you write.
Zero-knowledge architecture means the encryption key is derived from your password via Argon2id (64MB, 3 iterations) and never leaves your device. The server stores only cryptographic blobs prefixed with enc: — data that is literally noise without the key.
Your next novel, short story, or essay shouldn't appear in an AI training dataset before it's published. Protect every draft.
Confidential sources, ongoing investigations, sensitive drafts. Every byte needs protection that goes beyond a marketing promise.
Pitches, treatments, and in-progress screenplays are valuable intellectual property. Don't risk a leak by using the wrong tool.
Data under ethical compliance (GDPR, IRB), research notes, theses under construction. E2E encryption meets regulations by design.
The editor works like any premium editor — markdown, rich formatting, focus mode. The difference is that everything happens locally, in your browser.
Before any transmission, your text is shielded with AES-256-GCM on your own device. The key is derived from your password and never leaves the browser.
What reaches our servers is just a cryptographic blob — no meaning, no structure, no utility. We don't train AI, we don't read data, we don't touch what's yours.
| Criteria | WRITTT PRO | Traditional platforms |
|---|---|---|
| Is your text used to train AI? | Impossible — E2EE | Frequently yes (vague terms) |
| Can the provider read your documents? | No — zero-knowledge | Yes — server-side access |
| Protection against court orders? | Yes — we don't have the key | No — data is accessible |
| Real end-to-end encryption? | AES-256-GCM in the browser | TLS in transit only |
| Can employees access content? | Impossible — zero-knowledge | Possible — server-side encryption |
| Export without vendor lock-in? | PDF, Word, Markdown | Proprietary formats |
