Product Hunt’s Cronloop lets you describe a recurring job in Markdown, pick Codex or Claude Code, connect tools, and run agents on a loop with durable memory that can self-improve each run.
Users are spinning up a dedicated agent inbox: forward mail for it to act, CC it on threads for scheduling, and subscribe tools/newsletters to that address instead of a personal one.
A Reddit write-up: student feeds bill screenshots to OpenClaw agent Barry, which parses amount/due date, pays via encrypted AgentPay virtual card through Playwright portals, and texts a receipt—zero late fees in two weeks.
Jaxon Wright built a Grok Bot named Penny that reads bank charges and receipt emails, sorts subscriptions into likely-cancel / worth-a-look / keep, links each cancel page, and cancels only the ones you pick.
Hunter Gatherer uses a Grok Bot as company mission control: three daily interactive HTML snapshots styled like the company website, with APIs into key tools plus draft-and-send texts.

Paste an aging list and Invoice Chaser (built on Grok Bot) ranks who to chase, drafts friendly/firm/final reminders, and builds a send schedule—nothing goes out without approval.
