Start with useful everyday tools

Write

On-device ZNotes

Create and edit notes stored using operating system protected encryption. No TalkToAI web account is needed. Notes are not automatically synced; preserve important work with separate backups.

Connect

Your AI workspace

Connect an existing local model runtime, your self-hosted OpenZero server or a supported API provider. Review the active route before sending private material. Provider charges and limits apply.

Navigate

Bounded Browser Pilot

Grant one task in the isolated browser tab. The pilot has a 12-step limit, a visible Stop control and approval pauses for consequential actions. A supporting runtime must be configured.

Inspect

Selected-folder ZSEC checks

Choose a folder and review local results. No background scan, deletion, upload or quarantine starts automatically. This is an on-demand security companion.

Understand

Connection and storage status

See endpoint reachability, permissions and credential storage status. A status badge is not proof of protection. Optional Windows BitLocker status does not silently enable disk encryption.

Control

Edition-specific updates

Store apps update through Microsoft Store. Direct editions follow separate release instructions. The Store edition does not install local models or use a separate desktop updater.

Published release · 8.0

Local notes. A local research workspace.

ZERO ONE 8.0 brings encrypted ZNotes and the local ZeroThink research workspace together with user-configured runtime or API connections. Offline ZeroThink evidence maps require no model, hosted account or company database. Optional model-assisted research uses the provider you select.

Available now. Microsoft Store package 8.0.0.0 and the public GitHub 8.0 release were verified on 30 September 2026. Update through the channel used to install your edition; publication does not mean this computer has already updated.

Your first ten minutes

  1. Install and identify your edition. Use the Store listing or official repository instructions for your platform.
  2. Create a ZNote. Write a short note, confirm it reopens and plan separate backups for important work.
  3. Choose an AI route. In Settings, connect an existing local runtime, your own OpenZero address or a supported API profile.
  4. Try one small task. Send a short chat request. For Browser Pilot, open its isolated tab, describe one bounded task and grant that tab.
  5. Inspect a folder. Select a folder in ZSEC Shield and read findings, skipped items and errors. Keep existing operating system protection active.

Before you begin

Does ZERO ONE need a TalkToAI account?

No TalkToAI website account is needed for local notes. Optional APIs and runtimes may require their own credentials.

Are notes automatically backed up?

No. Notes remain on the device and user profile used by the app. Keep separate backups and follow the documentation before moving data between devices.

Can Browser Pilot operate every website?

No. It operates in a granted isolated tab within a bounded task. Passwords, payment fields, file inputs and CAPTCHA are outside the documented pilot workflow. Unsupported pages and approval pauses can stop a task.

Does the included scan replace my antivirus?

No. The selected-folder scanner is a security companion, without independent efficacy certification or guaranteed malware detection. Keep the operating system's existing protection enabled.
