Planning statements, specification schedules, client proposals, game design documents, technical reports. Claude, GPT, and Gemini in one studio.
Stensyl's document drafting tools are built for design professionals, not generic knowledge workers. Upload your renders, specify your brief, and get a professional draft structured exactly the way your discipline expects.
Most generative writing tools output generic prose. Design professionals need something else: a planning statement that follows local authority formatting, a specification schedule that respects trade sections, a client proposal that uses the right fee structure, a GDD that game publishers recognise. Stensyl's document models are trained and templated for professional deliverables. Drop in your project renders, pick a document type, and the output comes out structured for your discipline. Then edit inline with conversational AI, track revisions, and export to Word, PDF, or PowerPoint. Text models include Claude (Opus, Sonnet, Haiku), GPT (5, 4.1), and Google Gemini (2.5 Pro, Flash, Flash Lite). Pick the right engine for your task: Claude for long-form clarity, GPT for technical density, Gemini for speed and research grounding.
