Every 15 minutes, add new expense claims from my Typeform to a Google Sheet. If a claim is over 200, send it to my approver in Slack.

Should the approval alerts be sent by your connected Slack user account or by a Slack bot?

Should the approval alerts be sent by your connected Slack user account or by a Slack bot?

The draft is saved. It checks every 15 minutes, skips claims already in the sheet, and sends each new claim over 200 to your approver through the Slack bot.

More templates

Start the next one from a template, then change anything by asking.

Your coding agent writes it. Whenever runs it.

Ask Claude Code, Codex or Cursor to turn the task your agent repeats into a workflow. It writes the code, saves a draft and deploys it to Whenever through our MCP server. You connect the accounts and decide when it goes live.

MCP Setup Guide

01Ask your coding agent

Already have it somewhere else? An n8n workflow, a Claude task or a ChatGPT scheduled task: give it to your coding agent with our skill, and it reshapes it into a Whenever workflow and deploys it.

Turn this into a Whenever workflow and deploy it. Follow www.whenever.dev/skill.md

How the skill works

AI is brilliant at building. Wasteful at repeating.

Turn your agents into code: same result, a fraction of the cost, and the same steps every time.

Your agent is still thinking. Whenever is done.

For invoices, refunds and payouts, a 1% error rate is too much. Whenever makes the same decision every time.

Whenever runs your workflow in milliseconds. Nothing waits for a model to think it through again.

Whenever uses AI once, to write your workflow. After that, every run is almost free.

Need a reply written, a PDF read or a judgment call? Add an AI step in Whenever, only where you need it.

*For the steps that run as code. Add an AI step and that step can vary, and uses your plan’s AI spend in runs.

Don’t start from a blank prompt.

Pick a starting point, connect your accounts and review what Whenever builds before publishing.

The CRM your dental clinic runs on

Whenever it triggers, it works.

Triggers, credentials, run history and versions are built in. There's no server for you to run.

Webhooks, schedules, app events and on-demand runs.

You enter them once in the browser. Nothing to host, and your coding agent never sees a secret.

Every step’s input, output and error, kept 7 days on Hobby and 30 on Pro.

Every save is a version. Production keeps running the one you turned on until you switch, and any version exports as TypeScript you own.

While you build, the builder reads the logs and helps you fix it. In production, you get an email when a run fails, and fix it in the app or from your coding agent.

Start with one free workflow, no credit card. Upgrade when you need more workflows or runs. No per-step or per-item counting: one run is one run, however many steps it has.

The things people ask first

Who builds Whenever?Wix.com Ltd, the Nasdaq-listed company (ticker WIX). Whenever is one of its products, not a site built on the Wix website platform.

Follow the setup on whenever.dev/mcp: it shows how to connect Claude Code, Codex or Cursor and deploy your first workflow.

Yes, as a step in a workflow: an agent loop with the tools you give it and a capped number of turns, within a run of up to an hour. It sits next to fixed steps and single AI calls in the same workflow. Whenever is not an always-on chat agent.

No. You describe what you want in plain language and Whenever writes the workflow. The code is there when you want it, to read, to review, or to edit, and ignoring it is a perfectly normal way to use Whenever.

AI writes your automation once, as a typed TypeScript module, and every run executes that code. A workflow can be fixed steps only, call a model in one step where judgment is needed, or run an agent loop inside a step. The fixed steps follow the same rules on every run; AI steps and agent loops can vary between runs and draw on your plan’s included AI spend in runs.

Not for that step. Everything around it runs the same way every time, but an AI step asks a model, and a model can word its answer differently, or decide differently, from one run to the next. Th
