three answers, same engine.
scrb writes copy that sells. rankd judges culture honestly. tells reads what people leave unsaid — language-first ai for messages, people, and profiles. all three run on the same AI infrastructure. all three are live on paddle today.
scrb.
photo → description → sale.
drag a product photo. get a clean description, SEO title, meta-description, 5 bullets, and social copy in 25+ languages. one subscription covers amazon, etsy, shopify, woocommerce, ebay.
rankd.
name a title, i'll judge it.
type any movie, game, book, song, album, painter, painting, or author. get a scored verdict (out of 10), tier letter (S+ to F), and a short, honest opinion. mid is allowed.
tells.
opinionated ai that reads what people leave unsaid. three cores: read a message, read a person, read a profile. text-first, careful, direct.

different output. same craft.
the same five things matter for both: a fast model, an honest rubric, a good prompt, a hard daily cap, and a refusal to make things up. that is the whole moat. everything else (the UI, the pricing, the locale set, the screenshot frame on this page) is execution detail.
commercial copy.
- writes one description in ≈ 4 s, 600–900 tokens out
- 5 outputs from one prompt: full body, SEO title, meta, bullets, social
- platform-aware: amazon A9 vs etsy SEO vs shopify markup
- 25+ languages, native idiom for top 12 markets
honest verdicts.
- scores across 10 jury axes per category, weighted, not averaged
- tier letters S+ to F mapped onto the score band, not generated apart
- 11 categories: movies, shows, games, books, music (3), art (2), authors, podcasts
- vendor cascades: tmdb → igdb → google books → wikidata → deezer
one engine room.
both products share the same AI chokepoint, the same paddle billing wall, the same postgres schema for users, and the same redis-backed daily spend cap. when one ships an infra fix, both get it.
single-developer studio rules apply: monolith, no microservices, no kafka, no kubernetes. one repo per product, one server, one nginx.
both have free tiers.
scrb gives 5 generations a month. rankd gives 10 verdicts a day. either side is enough to decide if you ever want to pay us.
