ClaudeBox Private beta

Private beta · Chrome first

Your Claude conversations, on your schedule.

Set a prompt for an existing Claude chat and choose when the extension should try it. Start with Chrome; optional Windows Desktop support is available for testing.

No public Browser ZIP release has been published yet.

Your scheduled task runs only while its required browser or Desktop session is available.

Start with the browser

One extension. Your existing Claude chats.

Chrome is the primary target. The Chrome Web Store listing is not published yet, so this page shows private-beta setup instead of a made-up install link.

Private beta — no Chrome Web Store listing is configured.

Install the Browser package

  1. Download the Browser Extension ZIP below and extract it.
  2. Open chrome://extensions in Chrome.
  3. Turn on Developer mode, choose Load unpacked, and select the extracted Browser package folder.
  4. Open a Claude chat, then select Claude in Chrome in the extension.

A ZIP is a manual Chrome installation, not a one-click install. Chrome will show the requested permissions; review them before approving.

A small, clear workflow

Set it up once. Schedule when you need it.

Each task points to an existing conversation and keeps its target, message, and time together.

  1. Add the extension

    Install the Chrome beta package for now. A Store button will appear here only after a real listing URL is configured.

  2. Choose a conversation

    Use the current Claude tab or paste a chat link. Desktop mode lists chats Windows can identify.

  3. Choose a time

    Chrome makes the attempt when it is running. Desktop tasks also need the helper and Claude Desktop available.

Built around your existing chats

Scheduling with the important details in view.

Pick a time

Schedule a custom prompt at a date and time you choose. A refill time can be estimated manually; Claude’s countdown is not read automatically.

Stay in the browser

Choose the current Claude tab or paste an existing chat link. The extension checks the destination again before acting.

Add Desktop when needed

Optional Windows support uses a local native helper and UI Automation. It is experimental and requires a separate setup.

Protect drafts and sends

Unrelated drafts are left untouched. If a send may have happened, the task asks you to check Claude before retrying.

See task status

Review scheduled, sent, blocked, failed, and uncertain tasks with the next action explained.

Cloud scheduling is optional

Your own Cloudflare Worker and D1 database can store tasks and mark them due. A local extension still performs the action.

No public Cloudflare ZIP release has been published yet.

Try the interaction

A preview, not your Claude account.

This small demo changes locally in your browser. It never connects to Claude or sends a prompt.

  • Choose a mode and conversation
  • Edit a sample message and time
  • Schedule a demo task and inspect its status

Demo only. Nothing will be sent.

Good to know

Questions, answered plainly.

Is the Browser extension published in the Chrome Web Store?

The Chrome Web Store listing is separate and will appear only after a real listing is published and configured. If a Browser ZIP is published, download it from this page and load it unpacked in Chrome.

Does Browser mode have an in-app fee?

The extension has no in-app payment flow. Optional Cloudflare use follows the account and service terms you choose; Claude account or plan terms are separate.

How do I add a Browser ZIP to Chrome?

Download the published Browser-only ZIP, extract it, then open chrome://extensions. Turn on Developer mode, choose Load unpacked, and select the extracted package folder. Chrome will show the requested permissions before you approve installation.

Does it work in Edge, Brave, Firefox, or Safari?

Chrome is the target used for current testing. Other browsers are not confirmed as supported, and this site does not provide browser-specific install links.

Do I need Desktop mode?

No. Browser mode is the primary experience. Desktop is an optional Windows feature that needs the native helper and a separate manual Chrome extension setup.

Does my computer need to be available?

Yes. Local tasks run through Chrome while the computer is awake. Desktop tasks also need Claude Desktop open and signed in. Cloudflare can mark tasks due, but it cannot operate your local apps remotely.

Is Cloudflare required?

No. Local scheduling uses the extension on your computer. Cloudflare is an optional setup for people who configure their own Worker and D1 database.

What if Claude’s conversation or composer cannot be verified?

The task stops without sending when its target is ambiguous or unavailable. If a previous send may have reached Claude, check the conversation before choosing to retry.

How do I remove it?

Remove the extension from chrome://extensions. If you installed Desktop support, run the included uninstall script to remove the local helper and registration.
