Description

CoreTools brings six everyday tools for developers and IT pros into one fast, private desktop app. Everything runs on your PC: no account, no ads, no tracking.

• Diff-Checker: compare two versions of a file side by side, choose which side to keep for each change, and save the merged result.
• YML-Validator: check a Kubernetes manifest, strip server-managed and redundant fields, and get a clean, apply-ready file.
• Grammar-Polisher: spelling, grammar and style suggestions as you type, with one-click fixes, a rewrite in a professional, friendly or concise tone, and email checks. The grammar engine runs on your device.
• Authenticator: two-factor codes (TOTP and HOTP) with QR scanning, protected by a master password and optional Windows Hello.
• Credential-Manager: keep your logins in the same encrypted vault, sorted into spaces, with search, trash and an activity log.
• JSON-Studio: a full JSON workbench with validation, tree editing, JSON Schema, JSONPath queries, diff, repair, and conversion to CSV, XML, YAML and Excel.

Private by design
Your vault is encrypted with Argon2id and AES-256-GCM. The only feature that uses the internet is an optional Google Drive backup, which is end-to-end encrypted before it leaves your PC.

Before you uninstall: removing the app deletes its data on this PC. Export a backup, or turn on Google Drive backup, first.
