Why we built this

A long AI workday.
Then the browser crashed.

Hours of Claude analyses, ChatGPT concepts, Perplexity research — dozens of tabs, all the context in your head and on screen. One crash, and everything was gone.

We looked for a tool that saved our work locally, without funnelling it into yet another cloud service that reads our data. We didn't find one.

So we built Session Vault. First for ourselves — now for you.

Your data belongs to you.

Session Vault never sends your saved sessions to a server — no backend ever receives or stores your session data. It's how the extension is built, not a promise on a page. (Buying a license uses our payment provider Paddle; that's entirely separate from your sessions.)

Transparent by design.

No remote code (script-src 'self'), zero host permissions, and no broad data access — verify it all in the manifest yourself.

Pay once. Use forever.

Software you need once should be bought once. A one-time license, not a subscription trap — and a 30-day money-back guarantee if it's not for you.

How it works

Three steps. Thirty seconds.

No configuration, no sign-up, no setup. Install and start immediately.

1

Install

Add the extension from the Chrome Web Store — one click, no sign-up.

2

Capture a session

Save all open tabs with one click or the shortcut Ctrl+Shift+S — stored locally.

3

Restore anytime

Reopen a whole session or individual tabs with a click — even after a crash or restart.

Pro tip: keyboard shortcut

Capture any session in milliseconds without touching the mouse.

Ctrl + Shift + S

In action

This is your new workflow.

Session Vault sits quietly in the sidepanel — invisible until you need it.

Features

Everything you need tonever lose context.

Built for people who want full control over their tools — not the other way around.

Live context detection

Smart Session HUD

Session Vault detects which AI platform you're on and shows the live status of your active session right in the sidepanel.

Active claude.ai — detected, session is being saved
Ready chatgpt.com — one click to save

RAM optimization

Discards inactive tabs via chrome.tabs.discard — frees up RAM from tabs you're not actively using, without closing them.

Memory on large tab sets much lower

The local fortress

Export a physical JSON backup via the Downloads API — no server, no third party.

  "local": true,
  "server": null

Private cloud sync

Optional, opt-in sync to your own Google Drive (private AppData folder only) is on the roadmap. Today, Session Vault is fully local — with one-click JSON backup & restore.

Security

Transparent by design.

No remote code, minimal permissions, and a manifest you can inspect yourself.

manifest.json
Manifest V3
{
  "manifest_version": 3,
  "permissions": ["tabs", "tabGroups", "storage", "contextMenus", "sidePanel", "alarms", "downloads"],
  "host_permissions": [],
  "content_security_policy": {
    "extension_pages": "script-src 'self'; object-src 'none';"
  }
}

No remote code

A strict script-src 'self' policy means nothing executes from a CDN or external server at runtime.

No host permissions

Session Vault requests zero host permissions and injects no content scripts — it reads your tab list to save and restore sessions, but never the content of the pages you visit.

No tracking, GDPR-compliant

No analytics, no third-party scripts, no telemetry. Your usage is nobody's business but yours.

FAQ

Questions, answered.
