Features
Localized AI Copywriter is a micro-SaaS utility designed for non-native global tech founders and indie hackers. The platform leverages advanced language models to refine, polish, and optimize product marketing copy—such as landing page headlines, Product Hunt launch pitches, and App Store descriptions—into natural, high-converting, native-level English. To provide a frictionless user experience, the website features a “Zero-Auth” model where users can test and use the core feature instantly without creating an account. Monetization is handled seamlessly via usage-based credit packages.
Scene templates
Landing Page, Product Hunt, X posts, cold email, App Store, and more — each template constrains structure and length for the channel.
- Tone, audience, and length controls
- Three English variants with distinct angles per run
- Rewrite a single variant without starting over
Brand corpus
Store brand name, voice, preferred terms, and words to avoid locally. We inject them into generation prompts. Data stays in your browser.
History & favorites
Runs can be saved locally as history; star strong variants for later. Clearing site data or switching browsers removes them.
Character quota
New visitors get 1,000 free characters per day (`quota:free:*`, 24h TTL then re-init on next request). Each successful polish/rewrite deducts draft length — not model tokens or output size.
UI languages
The workbench UI supports Chinese, English, and more. AI output is always English marketing copy.
