AI Content Review for your GitHub Pull Requests

Launch Week at Cortex Click

This week we launched Cortex Click, a new platform for generating, editing, and publishing developer marketing content. Read on to learn more about why we built it, and why we believe it's a better approach to LLM-powered content creation.

Many modern teams build their content – think marketing sites, docs, and blog – with some sort of markdown builder like Hugo, Docusaurus, or GitBook. Today we're excited to release a new feature powered by the Cortex Click GitHub app: the ability to generate and iterate on this type of content using our LLM engine, right inside of a pull request workflow. All you need to do is tag @cortexclick in any pull request comment and you'll get a suggested commit that improves your content.


Imagine an engineer submits a PR to add docs for a feature they just built, and adds you as a reviewer. When you review a pull request you typically have two options when you encounter something you’d like to see changed:

  1. Add a comment and leave it to the PR author to do the work to incorporate the feedback.
  2. Take extra time to craft a suggested commit with the changes you’d like to propose.

With the Cortex Click GitHub app, all you have to do is tag @cortexclick in your review comment and you get a suggested commit for free, reducing the amount of work required by both the PR reviewer and author to incorporate feedback into a piece of content. All of which translates to better documentation in less time.

The Intelligent Content Engine

Readers who are skeptical of LLM-generated content will note that LLMs are prone to hallucinations and errors. We believe that quality (really) matters in documentation, blogs, and marketing. To generate the highest quality content possible, we employ a three-tier strategy:

  1. Grounding in your Knowledge Base: Cortex Click searches across your existing developer docs, blog posts, code examples, and other marketing materials to ground content generation, add cross-links, and match brand voice. We also automate the process of ingesting your knowledge base, and keeping it up to date.
  2. Real-Time Web Research: To fill in any gaps, the workflow performs web research against popular search engines.
  3. Multi-Agent, Adversarial Workflow: All of this context is fed into multiple state of the art foundation LLMs from four different providers that are used in concert. We pit them against each other to find and correct errors in their output, and combine the best parts in the final result.

In addition to GitHub-driven workflow, Cortex Click provides a fully featured markdown content generator and editor. Just provide a title and brief prompt, and Cortex Click generates a first draft.


The output is plain markdown rendered in a WSYWIG editor that supports inline editing and full markdown syntax.

LLMs hallucinate, and it's wise to be cautious of anyone suggesting otherwise. To speed up review on generated content, the editor provides AI-driven tools to iterate and get to a quality finished product faster. Use ⌘ K anywhere in the editor to generate new sections from a prompt. Highlight any existing section and hit ⌘ K to refine it with AI, either with open ended prompting or via builtins like spell check and shorten.


LLM generated content should be reviewed by humans for accuracy, but it certainly shouldn't create more work than it replaces. Our tools, including the Cortex Click GitHub app, are designed to take advantage of human review where it's already happening.

One Click to Publish to GitHub

The Cortex Click GitHub app enables publishing content created within the Cortex app as a GitHub pull request with one click.


With the GitHub app, Cortex Click natively integrates with your existing content workflows like Vercel preview builds, linting, and deployments on merge via GitHub actions.

Software Should be Easy to Use

We believe that software should be easy to use. Users should have answers to their questions readily available, supported by high-quality documentation that simplifies the onboarding process. Regardless of whether a company has a large content marketing team or not, every product deserves top-notch documentation and marketing materials. We're building Cortex Click because the way the industry creates developer content is flawed, slow, and broken. Today we're sharing the first step towards a future where developer content is generated in real time as you ship new features, and content is updated automatically before it has the chance to get stale. Come along for the journey.
