Claude Prompt Scheduler от Abhinav Biju

Schedule a prompt to be typed and auto-sent into claude.ai at a chosen
time — including multi-step sequences, and an optional prompt library
you can sync across devices.

HOW TO USE IT
1. Click the toolbar icon, type your prompt, pick a date/time, and
Schedule.
2. Keep Firefox running (minimized is fine) until that time — it doesn't
need to be the foreground window, but the browser process must be
alive and your machine awake.
3. At the scheduled time, the extension finds an open claude.ai tab (or
opens one), types your prompt, and clicks Send. You need to already
be logged into claude.ai — this extension doesn't handle that login.

FEATURES
- Fixed-time or auto-detect scheduling (auto-detect waits until a
rate-limit message clears, then sends).
- Multi-step sequences: chain several prompts together, optionally
branching on keywords in Claude's reply.
- Choose where a job sends: your current tab, a brand-new chat, or a
specific existing conversation.
- File attachments on scheduled prompts.
- Auto-retry for fixed-time jobs that fail to find the input box or
send button (up to 3 attempts).
- Dashboard: search/filter/edit the live queue.
- History: a log of every send attempt (sent, failed, retrying, missed).

OPTIONAL: PROMPT LIBRARY & ACCOUNT (not required for the above)
- Browse a shared library of prompt templates; save your favorites.
- Sign in with Google (or, once available, link an email) to sync your
saved library and personal templates across devices, and to submit,
rate, or review catalog prompts.
- Link multiple Firefox profiles into a "workspace" to route jobs and
share templates between them.
This is entirely optional — everything above works with no account, and
your scheduled prompts and history are always stored locally on your
device regardless. Full details on what's stored where: see the Privacy
Policy link on this listing.

LIMITATIONS
There's no official claude.ai API, so this works by finding page
elements (the message box, send button, rate-limit text) — if claude.ai
changes its page structure, scheduling or auto-detect can stop working
until updated. This fails safe (it just doesn't fire) rather than
sending to the wrong place.
