Dialog vs Shopify Sidekick (2026)
Two agents in the commerce stack aimed at different people.
Sidekick serves the merchant inside the Shopify admin, carrying out operations from natural language grounded in store data, included in merchant plans, documenting 8 of 14. Dialog serves the shopper, encoding a brand's identity and expertise to advise and sell both on the site and inside AI assistants like ChatGPT and Gemini, at 7.5. Dialog's reach into assistants is the interesting part: it is a bet that a growing share of shopping conversations start somewhere other than your website.
Choose Dialog if
- Customers increasingly ask ChatGPT and Gemini before they reach your site, and you want to be there.
- Encoding brand voice and product expertise into the agent is the differentiator you need.
- Advising and selling to shoppers is the job, not running the back office.
Choose Shopify Sidekick if
- Merchant operations are what eat your time and it is already in your Shopify plan.
- Documented coverage is slightly broader and grounding is automatic.
- You want zero integration work and something usable today.
