Cursor for Technical Design Docs and PRDs
The best way to stream LLM thinking traces to your frontend
Lightski is the Cursor for Engineering Docs: a rich-text editor and AI assistant specifically built for engineering managers and tech leads. Whether you’re writing a technical design doc, internal documentation, PRD, or peer review, Lightski helps you write higher quality documents faster with the help of AI. Lightski connects to your Github and comes with an AI agent that pulls relevant context from your codebase to help you draft. Afterwards, continue refining in our Notion-like editor, where you can collaborate, iterate, and comment on the doc.
Streamstraight ensures your users never see an interrupted LLM response. We solve the problems around resumable streams and reconnecting during an in-progress AI response, so you can ensure your long-running AI agents responses are never interrupted on the frontend. If you… * show an incomplete response when users return to an AI chat that's still in-progress * have users who request multiple long-running AI responses, simultaneously * lose data when a client reloads the page during a stream * deal with flaky connections due to mobile clients * want to run LLM inference from an async job * want to stream the same LLM response to multiple browser tabs/clients …message us! We can fix these issues and ensure your frontend stays high quality during long-running streams.
The company shifted from building an AI-enabled editor for technical documents (targeted at engineering managers and tech leads) to providing infrastructure for streaming live LLM responses in applications (targeted at developers integrating LLMs). This is a complete change in product, target customer, and problem.
