What it is
A native ad-copy generator and validation workspace for Mac. Describe a product, angle, audience, benefits and tone once; choose Meta, Google, LinkedIn or all three; then edit three variants per platform beside live previews, field-level character budgets and a transparent heuristic hook score.
Refract keeps the campaign brief and the generated ad set in one native Mac window. Enter the product, angle, audience and concrete benefits, choose a bold, friendly, professional or playful tone, and select the destinations you need. With all three platforms selected, the same brief becomes three Meta variants, three Google variants and three LinkedIn variants, each split into headline, primary text, description and call-to-action fields.
Every variant remains editable. Refract shows the text inside a platform-shaped preview and counts each field as you type using Unicode grapheme clusters. The visible budget changes by platform and field, with near-limit and over-limit states surfaced immediately. Its 0–100 hook score is deterministic: it rewards disclosed copy signals such as useful hook words, an appropriately sized headline, a question or number, a concrete CTA and substantive primary text, while penalizing empty or over-limit fields. It is a drafting heuristic, not a forecast of clicks or conversions.
Generation always has a local deterministic path and does not require a model account. If a supported provider is available, Refract can ask Apple Intelligence, Ollama, LM Studio or a bring-your-own cloud model for enriched variants. Model output is accepted slot by slot only when all four fields exist, every field fits and numeric or risky claims are supported by the supplied brief. Otherwise that slot returns to the fitted deterministic variant instead of presenting unsupported social proof, free offers, superlatives or statistics as ready copy.
Copy a single field, a whole ad with clean paragraph spacing or the complete Markdown ad-set report. The report records the campaign summary, selected platforms, average hook score, over-limit count, every variant and every field validation. Edits made in the live workspace flow into the report. The separate website Direct edition is Developer ID-signed and Apple-notarized, permanently unlocks all-platform generation and full reports after one purchase, and contains no StoreKit subscription or in-app purchase path.
How it does its job
Three variants per platform
Create headline, primary text, description and CTA fields for three distinct slots on every selected destination.
Editable destination previews
Review and change copy beside a Meta feed post, Google search ad or LinkedIn sponsored-card preview rather than in an abstract text list.
Live character budgets
See grapheme-aware counts, remaining space and clear near-limit or over-limit states for each field as the copy changes.
Grounded generation fallback
Use deterministic templates with no model, or connect an optional provider; incomplete, over-limit or unsupported model slots fall back to the grounded local version.
Report-ready handoff
Copy individual fields, complete variants or a Markdown report whose ad copy and validation details reflect the latest live edits.
What it doesn't do
Refract drafts and validates text; it does not create images or video, publish campaigns, connect to ad accounts, manage spend, run experiments or measure results. Its previews are representative layouts rather than exact network rendering, and platform specifications and policies can change, so confirm current requirements in Meta, Google and LinkedIn before publishing. The hook score is a copy heuristic, not a performance prediction, compliance review or factual approval. Grounding checks look for unsupported numbers and a defined set of risky phrases; they cannot prove every claim true or catch every policy issue, and all generated copy still needs human brand, factual, legal and platform review. The current workspace holds one active campaign in memory and exports by clipboard rather than providing a saved campaign library or file export. Local providers require their own running service, Apple Intelligence depends on supported Apple hardware and macOS availability, and a cloud provider receives the submitted brief through that provider under its terms.

Common questions
What is Refract?
A native ad-copy studio for Mac. Turn one product brief into three editable variants each for Meta, Google and LinkedIn, inspect every field against its platform character limit, compare deterministic hook scores, and copy individual ads or a complete Markdown report.
Who is Refract for?
Refract is for founders, product marketers, paid-media teams and agencies drafting review-ready ad copy for Meta, Google and LinkedIn. Turn one campaign brief into editable Meta, Google and LinkedIn ad variants, validate every field, and copy a complete report.
Does Refract run on macOS?
Yes. Refract is a native Mac app and runs on macOS 14+.
Does Refract need AI to generate ad variants?
No. Its deterministic generator creates fitted variants and validates them locally without a model, API key or Refract account. A supported model is optional enrichment, and every returned slot still faces the same completeness, grounding and character-limit checks.
Which ad platforms does Refract support?
The current version supports Meta, Google and LinkedIn. You can select one, two or all three; Refract creates three variants for each selected platform and applies the field budgets built into the app for that destination.
What does the Refract hook score mean?
It is a disclosed 0–100 drafting heuristic based on copy features such as hook words, headline length, questions or numbers, CTA presence, primary-text substance and limit compliance. It is not trained on your ad account and does not predict reach, clicks, conversion rate or revenue.
Is the website edition fully unlocked?
Yes. The separately built Refract Direct edition permanently enables all-platform generation and complete reports and excludes the App Store paywall and StoreKit code. It is a one-time website purchase with no subscription, account or trial timer.
Is this the same Refract edition as the Mac App Store version?
No. The Mac App Store edition can include Apple's in-app subscription system. The website Direct edition is a separately signed build with no StoreKit purchase flow: one website purchase unlocks the complete app with no recurring charge.
Is Refract the full version, or are features locked?
The download is the complete app. There is no subscription, no locked tier, no account, and no trial timer — every feature is included.
