What is Lightski?
Lightski is an AI‑powered rich‑text editor and documentation assistant built specifically for engineering teams and technical product managers. It helps write, maintain, and keep engineering‑oriented documents—such as design docs, PRDs, post‑mortems, API guides, and internal wikis—up to date by watching your codebase and other repositories. The tool integrates with GitHub and similar code hosting platforms to detect changes and automatically propose updates through pull requests, so technical writers and engineers do not have to manually track which docs need revision.
Lightski is designed for engineering managers, tech leads, senior engineers, and product managers who rely on accurate, current technical documentation but lack dedicated technical‑writing resources. It aims to reduce the overhead of maintaining docs by combining AI‑assisted drafting with event‑driven code‑aware editing, so teams can ship confident, well‑documented features without extra context switching.
Key capabilities include AI‑driven drafting and autocompletion, code‑aware suggestions tailored to your repository, multiplayer collaborative editing, and template workflows tuned for common engineering‑doc patterns. Lightski also includes Slack integration so team members can trigger doc updates or revisions directly from chat, tightening the loop between code changes and documentation hygiene.

- Some advanced features may only be available in higher‑tier plans
Frequently asked questions about Lightski
What is Lightski and what does it do?
Lightski is an AI‑powered rich‑text editor specifically built for engineering teams to write and maintain technical documentation, such as design docs, PRDs, post‑mortems, and internal wikis. The editor watches your codebase via GitHub integration and can automatically propose doc updates through pull requests when code changes are detected, helping keep documentation in sync with the code.
Who is Lightski built for?
Lightski targets engineering managers, tech leads, product managers, and engineers who need to write and maintain high‑quality technical documentation but lack dedicated technical‑writing bandwidth. It is especially useful for teams that want to reduce the overhead of manually tracking which docs become outdated when code evolves.
How does Lightski integrate with GitHub?
Lightski connects to your GitHub repositories so it can understand your codebase and detect changes that may affect documentation. When relevant changes occur, Lightski can automatically open pull requests with suggested updates to the linked documents, or allow users to request an update manually from Slack or the editor itself.
Does Lightski support multiplayer or real‑time collaboration?
Yes, Lightski is built as a multiplayer‑enabled rich‑text editor, allowing multiple team members to collaborate on the same technical document in real time. This is intended to streamline co‑authoring, reviews, and approvals for design docs and similar engineering artifacts.
How does the AI assistant inside Lightski work?
Lightski's AI assistant provides autocompletion and draft‑generation capabilities directly inside the editor, and can be triggered with a tab or similar shortcut. The assistant is code‑aware, meaning it can reference patterns and structures from your connected codebase to suggest more contextually appropriate wording and examples in your docs.
What happens when my codebase changes?
When Lightski detects changes in your codebase that likely affect documentation—such as renamed APIs, new endpoints, or restructured services—it can propose updates via automated pull requests. Alternatively, you can manually request an update from Slack or the editor interface and Lightski will regenerate or refresh the relevant sections.
Can I use Lightski without a GitHub account?
While Lightski is primarily designed around GitHub integration to power its code‑aware suggestions and auto‑update workflows, smaller use cases involving basic technical writing may still be possible on the free tier. However, the full value of code‑aware pulling and automated PRs depends on connecting at least one GitHub repository to the tool.
Is there a free plan and what does it include?
Lightski offers a free plan that supports up to 1 team member and includes 5 AI chats per month along with basic email support. This tier is intended for individuals or very small teams who want to try the editor and AI assistance without committing to a paid plan.
What is included in the paid Pro plan?
The Pro plan, priced at about 19.99 USD per month, includes everything from the free tier plus unlimited documents and AI chats, as well as custom doc templates tailored to your team's workflows. This plan is aimed at growing engineering teams that want to scale their documentation output without hitting usage caps.
Can I get help if I want Lightski for my entire company?
For company‑wide pilots or enterprise‑scale usage, Lightski invites teams to contact the founders directly via email to discuss custom plans and onboarding. This allows organizations to tailor access, permissions, and integrations to their specific engineering and documentation needs.
