Privacyand Encryption.
Writtt is a rich text editor that lives on your computer — full stop. Open source, no subscriptions, no forced sync with cloud, no companies reading your texts. No data leaves your computer unless you want it to.
macOS · Windows · Linux · Made by one person in Brazil
Every time I open a new document it's the same moment: a blank page, no notification badge, no one watching. That's the point. Writing to think — not to publish, not to be seen thinking.
Privacy as a condition
There's no honest writing under surveillance. When you know someone might read, you edit before you write. Your ideas arrive pre-censored by the fear of an audience.
Writtt has no server. No account. No analytics on how long you spent on that note. Your words stay here.
This isn't a feature
- It's the whole product
- Local-first by principle, not by limitation
- AES-256 for what you prefer to keep private
- Offline always — not when the connection allows
Your words are yours. Completely.
Some things aren't for anyone else.
Writtt was engineered as a digital vault. Every layer of protection ensures your words exist only for you — even if someone gains physical access to your device.
AES-256 Encryption
Military-grade. Each vault document is individually encrypted with keys derived from your password.
Zero Servers
Your data never leaves the device. No cloud, no server, no interception.
PIN Lock
Vault access requires local authentication. Without the PIN, files remain cryptographic noise.
Local Storage
100% offline-first. Your documents live exclusively on your disk — invisible to any network.

"There is no honest writing under surveillance."
We live in an era where AI has been embedded into absolutely everything — text editors, notepads, journals. Every word you type can become training data, behavioral analysis material, or simply sit exposed in a breach no one will admit to in time.
Writtt was built in the opposite direction. Local AES-256 encryption, no central server, no user account, no telemetry. Open source so anyone can read what happens under the hood. Not for marketing — but because a writing app without privacy is a betrayal of its users.
For those who love to write, the ideal editor disappears. You forget it exists and only hear your own voice. This digital silence — rare, precious — is what we set out to preserve here.
Local encryption
AES-256 on device. No key on any server.
Open source
Anyone can audit. Trust built on code, not promises.
Zero telemetry
We don't track what you write, when you write, or for how long.
Local & Secure AI
Native integration with Ollama on your device. Interact with AI without betraying your privacy.
Download
Download. No sign-up.
Click, install, open. No email asked, no account created. Just the app.
No code-signing certificate — and that's intentional.
Windows and macOS may show a security warning on first launch. The app is safe: it makes zero network calls, all code is open source, and you can build it yourself from the source. The warning exists because signing certificates cost $99–$400/year — a real cost for a free, indie project.

Open Source & Self-hosted
Your binary. Your rules.
Writtt is free, open source, and ships with zero network calls. Build it yourself or download the binary — either way, you own it completely.
Fully verifiable
Build from source and inspect every line before it ever runs on your machine. No trust required.
Zero telemetry
No analytics, no pings, no usage tracking. The app makes no outbound network calls at runtime — ever.
Works offline
Local-first by design. Your notes live on your disk and are accessible without an internet connection.
Community-driven
Open source means anyone can contribute fixes, features, and improvements. You're not waiting on a roadmap.
Native performance
Built with Go and Wails — not Electron. The binary is lean, fast to start, and light on memory.
Yours forever
No subscription, no cloud lock-in. The app keeps working regardless of whether the company behind it exists.
Free for you. Not for who builds it.
"The model asks you to pay to be legitimate, and to prove legitimacy before being seen."
Distributing free software doesn't mean producing it is free. The companies that dominate the desktop ecosystem have found an elegant model: charge developers for the right to exist inside their platforms.
To sign a macOS app without a “unidentified developer” warning, you pay USD 99/year for the Apple Developer Program. To publish on the Microsoft Store, another USD 19. That's before counting the code-signing certificates some tools require — which can easily run USD 300/year through certificate authorities.
But there's a cost money can't fix: reputation. Tools like antivirus filters and Windows SmartScreen evaluate new software based on how many people have already downloaded it. It's gamification that punishes newcomers. The app is safe — but how do you prove it when no one knows you yet? You need to farm downloads to earn an algorithm's trust.
Apple Developer Program
Required to sign and distribute outside the App Store without security alerts.
Microsoft Store
To publish on the official store. Doesn't eliminate SmartScreen warnings.
Code Signing (Windows)
EV certificates reduce (but don't eliminate) SmartScreen alerts.
SmartScreen Reputation
Can't be bought. Accumulates over time as users override the warning.
