Made for Shopify stores
Good copy starts with who it’s for.
Bring your product facts, brand voice and customer context together. MessageFit drafts copy for the audience you choose, checks its evidence, and keeps you in control of what goes live.
Preparing for Shopify App Store review.
Public installation opens after approval.
Claude-powered drafts. Merchant-reviewed descriptions.
Context that belongs to your store.
Save your positioning, verified policies and brand voice. Create up to five customer profiles and choose one for each batch. Order cohorts show purchasing behavior; your expertise supplies the motivations that numbers cannot establish.
Review six fields of copy and the evidence behind them. Publishing updates the approved product description only. Version history and saved originals support rollback, with checks for later changes made in Shopify.

$9 per 10 additional updates
Prorated at $0.90 per successfully published description after your included allowance. Drafts, failed publications, and rollbacks do not incur usage charges. Unused included updates expire at the end of the billing cycle.
The trial includes 10 published updates and 30 AI product draft attempts, with no usage charges. Publishing pauses at the trial limit. Each requested product counts as one draft attempt, including batches that fail review. These attempts carry no additional charge. Paid draft allowances help keep AI usage predictable; extra draft generation requires an upgrade.
Launch plans are prepared. Paid subscriptions open after Shopify billing verification and release.
A few useful details.
What counts as an update?
One successfully published product description. Drafts, failed writes and restoring an earlier description do not incur usage charges. Publishing another approved version counts as a new update.
Does MessageFit measure conversion lift?
The launch app provides order-cohort insights and copy review. It does not yet collect storefront sessions, conversion rates or A/B test results.
Does Claude receive customer records?
Model requests contain the selected store context, product facts and aggregate order insights. Individual customer records are not sent to Claude. Avoid entering personal customer details in messaging fields.
