Live on the VS Code Marketplace · Free essentials · v0.1.0

Your AI pair programmer doesn't need your production keys.

Sether for VS Code underlines personal data and secrets while you work, hands your assistant a scrubbed copy, and restores the real values when you paste the answer back. Text processing stays on your machine; new licensed builds contact Sether only for explicit license activation and renewal, with no background polling.

Install from the Marketplace Open in VS Code

code --install-extension GodfreyLebo.sether

The current Marketplace build may retain legacy free features. The forthcoming licensed release shares one Pro user bundle with Shield: $5/month or $48/year, manual renewal. Install a compatible build before opting into the no-card seven-day trial. See pricing for pilot availability.

See it in action

Ask your assistant anything. Keep the secrets.

An illustrative walkthrough of the current extension. New licensed releases label decoys and custom controls as Pro; viewing this demo does not start a trial.

1/6

Open any file. Sether scans supported patterns in your file locally. New licensed builds use separate activation and license-refresh requests; file contents are not uploaded.

Features

Local text processing. Clear plan boundaries.

Squiggles as you type

Emails, phones, cards, SSNs, IBANs, IP addresses, vendor API keys, JWTs, database URLs, .env secrets and PEM keys appear in the Problems panel.

Quick fixes

Mask or redact from the lightbulb menu. Pro in new licensed releases adds realistic decoys.

Copy Scrubbed

Copy a selection with every sensitive value replaced by a token, ready for Copilot, Cursor or Claude.

Paste with Originals Restored

Paste the assistant’s answer and the tokens turn back into the real values, in your editor only.

Scan the workspace

Scan supported patterns across the project and review findings. Detection can miss information.

Fits how you work

Use ignore comments and an allowlist for test values. Pro in new licensed releases adds custom watchlists; review workspace-trust restrictions before use.
