What to ask for

Things Shopify can't do on its own

Say it the way you'd say it to a person. The agent finds your products and collections, picks a ready-made setup when one fits, and tests the result before it shows you.

How to connect

Two minutes, no keys to copy

  1. Sidekick

    Install Otherwise, then ask Sidekick in your Shopify admin: "Create a discount with Otherwise: …". It opens the draft in Otherwise for you to check.

  2. Claude or ChatGPT

    Open Agents in the app and click the tile. Claude opens its connector form with Otherwise's address filled in; ChatGPT opens a chat with the setup written.

  3. Grok Bot, Muse and others

    Click the tile to copy the setup, and paste it to your agent. Any agent that can add an MCP connector works.

  4. Approve it in Shopify

    The agent sends you to your admin to sign in. Choose what it may do: read, draft, or publish. You can remove its access on the same page at any time.

  • It drafts, you approve

    A draft never changes checkout. Whatever an agent saves is marked as its work, for you to read, test and switch on.

  • You set what it may do

    Read your rules, also draft new ones, or also publish them. Change it or remove it whenever you like.

  • Tested before you see it

    The agent runs the rule on carts just under and over every threshold, and tells you what each one got.

Questions

About agents

Which agents work with Otherwise?

Sidekick in your Shopify admin, and any agent that can add an MCP connector: Claude, ChatGPT, Grok Bot, Muse and others. The Agents page in the app has a tile for each of the four.

Can an agent change my checkout without me?

Only if you allow it. When you connect an agent you choose whether it may read your rules, also draft new ones, or also publish them. A draft never changes checkout, and whatever an agent saves is marked as its work.

How do I stop an agent?

Open Agents in the app and remove its access. It stops at once.

Is it on every plan?

Yes. Agents work on every plan, Free included. A plan only sets how many rules can be live at checkout at the same time.

What can Sidekick do on its own?

On its own, Sidekick makes amount-off and free-shipping discounts. Through Otherwise it can build the rest: tiers, mix and match, conditions, delivery and payment rules, limits and bundles.
