Show HN: MyWritingTwin: an AI Writing Profile that makes LLMs sound like you
MyWritingTwin is an AI tool that creates a personalized writing profile, enabling large language models to generate text that matches a user's unique style and voice.
Background
- MyWritingTwin lets you create a personal "writing profile" that other AI tools (like ChatGPT, Claude, or Gemini) can reference to mimic your unique style, vocabulary, and tone — instead of the generic "AI voice" most LLMs default to.
- The core problem it solves: Large language models (LLMs) produce bland, recognizable output unless they're given detailed style instructions. Existing solutions (custom GPTs, system prompts) are clunky or platform-specific.
- This is part of a growing trend of "personalized AI" — tools that learn an individual's voice rather than forcing everyone into a one-size-fits-all assistant template. It matters because as AI writing tools become ubiquitous, standing out and sounding human is increasingly valuable for professionals, writers, and marketers.
- The product surfaced as a "Show HN" (Hacker News showcase), indicating it's an early-stage or indie project being shared for feedback with a technical audience.
