About ScriptGrain
ScriptGrain analyses 45 measured reference points across a user’s writing to build a voice profile that generates content matching their style. Users upload existing writing samples which are processed in two passes to create a comprehensive profile covering vocabulary, sentence rhythm, punctuation habits, and unconscious word choices. The tool then generates drafts from briefs while adhering to the profile’s constraints across sixteen content types. Each draft receives a voice-match score, and a polish loop revises content when scores fall short. The platform includes a public API and MCP server for integration with AI assistants like Claude. ScriptGrain operates under a privacy-first model where user writing samples are never used to train AI models. Plans range from a free tier with one profile to enterprise options with unlimited profiles and team features.
