Lightski

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.

Engineers (broadly speaking) hate writing

As an eng manager and tech lead, I spent a significant chunk of my time writing all kinds of documents: design docs, post-mortems, internal documentation, etc. Luckily I enjoyed it, but most didn’t! We built Lightski because AI tools like Cursor have significantly sped up how engineers write code, but not yet for documents.

Whether you’re writing a technical design doc for your promo packet or summarizing an incident in a post-mortem, Lightski helps you create a polished document in less time.

In a world of AI Slop, Lightski emphasizes Human Expertise

Lightski does not generate documentation on autopilot. That kind of documentation has little value, because the real value is in the human insight and context that does not exist outside of your brain. Instead, Lightski assists with the act of writing—turning your unique idea into a polished document.

We’re building the best possible text-editor for humans to communicate in a written format. As long as you provide that idea, Lightski helps with the tedious bits! For example, Lightski can quickly convert code into a Markdown table:

AI-powered Notion-like editor integrated with Github

How can Lightski help? Lightski natively bundles AI with a powerful text-editor and access to Github. By directly working with the document, our assistant can:

• Explain the logic in your codebase
• Pull schemas from code into a document
• Rewrite code into tables or bullet points
• Create a draft with references to your codebase
• Brainstorm different approaches to a gnarly problem
• Search and reference online documentation
• Polish up wording and fix grammar
• and more!

Continue editing, commenting, and collaborating with teammates in our multiplayer text-editor. Stop copy-pasting from ChatGPT or Claude—just work directly with them in the canvas. Lightski includes targeted AI features, such as full suggestions, to fight writer’s block.
