Prompt Later — AI Chat Scheduler

Schedule messages in your existing AI chats. Local storage, one-off sends, and recurring schedules.

Send later for your AI chats. Choose an existing conversation, a time, and a message. Prompt Later attempts to send your message to that saved conversation while your browser is running and your computer is awake. FEATURES Capture the current conversation URL or paste one. See attention counts on the toolbar when delivery needs review. Schedule once: in five hours, in one minute for testing, or at a chosen date and time. Repeat every N hours, daily, on weekdays, or using a five-field cron expression and time zone. Save multiple messages, edit schedules, pause jobs, and review delivery activity. Reuse the matching conversation tab or open it in the background without switching your active tab. Choose whether an existing composer draft is preserved, sent, or replaced; the safe default preserves it and skips that occurrence. Never repeat a one-off after sending may have started. If the browser interrupts an attempt before that boundary, Prompt Later may safely resume it and still applies the chosen late-run policy. Recurring schedules continue with their next occurrence after a blocked, skipped, or uncertain run. LOCAL ENCRYPTION, NO EXTRA SIGN-IN Saved messages, conversation URLs, schedules, and activity are automatically encrypted locally with AES-256-GCM using a browser-held non-exportable device key. No passphrase is required and there is nothing to unlock, so schedules resume by themselves after browser restarts and extension updates. Someone controlling the browser or profile may still access the data. You can review how this works under Advanced privacy in the full dashboard. No extra account, extension backend, telemetry, or AI API key is required. Messages are delivered through the provider website using your existing signed-in account. The provider processes messages under its own terms and privacy policy. BETA COMPATIBILITY ChatGPT and Claude integrations are supported. Additional AI chat integrations are experimental. Automated tests use simulated provider pages; they do not guarantee live compatibility. Website changes, login state, and account limits can prevent delivery. IMPORTANT LIMITS Keep the browser running and the computer awake. Turning off the monitor is fine. Alarms can be delayed and cannot wake the computer. The five-hour option is a convenience delay, not quota-reset detection. Prompt Later does not bypass account limits or guarantee that an AI will finish its work. Sent means that the page acknowledged the message, not that the response is complete. Prompt Later is an independent utility and is not affiliated with the supported AI providers.
