Movement

This is the first edition on this tier, so no move can be computed for Postscript yet. From the next edition this section shows, per buyer segment and per category, whether its share moved by more than the measured noise floor.

By model

How each model treated Postscript across every prompt where it was named for a mid-market B2B company. Fourteen models, six prompts per category.

What the models said for it

Verbatim evidence the judge attached to positive labels.

“Deepest Shopify SMS integration available... Supports Shopify and nothing else, so a platform migration means rebuilding your SMS program from zero.” Muse Glimmer 30B · Mobile & push · comparative prompt · alternative
“alternatives like OneSignal, Klaviyo, or Postscript, which are generally better suited for lean teams” Mistral Small · Mobile & push · negative prompt · alternative
“Better Alternatives: *Klaviyo, Sendlane, or Postscript* (using standard, non-enterprise tiers)” Gemini 3.5 Flash · Ecommerce marketing · negative prompt · alternative
“Choose a managed provider (like Postscript, SimpleTexting, or SMS8) that handles 10DLC compliance” Gemini 3.5 Flash · Mobile & push · negative prompt · alternative

And against it

Verbatim evidence attached to negative labels. A warning on a product with few labels is a warning; on a product with many, it is one voice among them.

“Frequent 2024–2026 reviews cite undelivered messages while charging, $500/mo platform fees... support declines, auto-renew traps, and refund denials.” Grok 4.20 · SMS & WhatsApp · negative prompt · hard negative
“Some users have reported: Poor customer service experiences - Challenges with cancellation and refunds - Charges after unsubscribing” MiniMax M2.5 · SMS & WhatsApp · negative prompt · hard negative
“Frequent user complaints on Shopify reviews | Poor customer service” Grok 4.20 · Mobile & push · negative prompt · hard negative
“Postscript (Watch Your Service Tier) ... polarized reputation regarding customer support and billing” Qwen 3.7 Flash · Mobile & push · negative prompt · soft negative

What carried it into the answer

The sites and pages cited by the answers that named Postscript. A fact about retrieval, not a lever on the model.

Citations exist only for the models that return a source list, five of the fourteen in this edition, so these counts come from 49 of the 57 answers that named Postscript and are not a share of its labels.

Search figures are US estimates from DataForSEO, read September 28, 2026; AI search demand is its modeled, directional estimate, not a count of queries to any assistant. The answers are this edition's. Two measurements side by side: neither is read as the cause of the other.

How it is countedHide how it is counted

Every page postscript.io exposes, subdomains included. Kind is read from the address and title. The last 90 days, the latest date and the twelve months count pages by when they were published, from the site's feeds, a date in the address, or the page's own publication date, read from up to a hundred of its most recently changed pages; a page that says only when it last changed is counted in its kind but not in when, so the recent counts are a floor, and a kind none of whose pages gives a publication date reads undated. An event counts as online when its address or title says so (webinar, on demand, virtual or online summit); a conference, summit, trade show, expo or roadshow that does not say so is counted as a conference or event, which on a vendor's site is mostly in person.

Is this your product?

Claim this page

Claiming is free and changes nothing in the data. A claimed page shows a verified contact who is told when each edition publishes and when Postscript's standing changes by more than the noise floor; the right to propose corrections to the vendor table, meaning names the judge wrote that should or should not read as Postscript, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.

What a new claim receivesHide what a new claim receives

A new claim receives the current edition's vendor brief for Postscript by email, built from the raw record of the edition. It shows:

  • where Postscript is named, by buyer and by framing, and which cells hold its first choices;
  • the claims the models make when they name it, ranked, with the strongest and the weakest quoted;
  • its vocabulary against the segment leader's, and the pages the models cited;
  • who was chosen in the answers that did not name Postscript, and every reason the record gives;
  • a battlecard for each top rival: the head-to-head split, why they win, and the reservation quoted against them;
  • one page of published figures cleared to show a buyer.
The subscriber app

A verification link goes to your work email; an address at postscript.io is approved on the spot, any other is reviewed by hand. Your email is never published. Claiming gives no say over labels, shares, verdicts or which quotes appear.
