Comments on my blog like Google Docs? 'Sidenote', the tool where AI writes the code changes for you

AI Summary

Sidenote is an innovative collaboration tool that lets readers comment on blog posts, which an AI then analyzes and automatically converts into Git code changes.

Imagine this: someone is reading your carefully crafted blog or technical documentation, and they think, “The wording here is a bit awkward, what if we changed it to this?” They leave a suggestion just as easily as they would in a Google Doc. But the surprising part? The artificial intelligence (AI) reading that comment doesn’t just reply—it perfectly writes out the “Git diff” (a technical method for showing only the specific changes made to the code) so that you can directly apply the fix to your blog’s source code.

A tool has arrived that makes this magical experience possible. It is called ‘Sidenote’.

Why does this matter?

Document collaboration is always a difficult task for developers and technical bloggers. Usually, if someone wants to suggest a typo or phrasing fix, they have to access the repository where the blog’s source code is stored (an online space where code is kept) and submit a “Pull Request” (a request to incorporate code changes). For an average reader without technical knowledge, this process is an incredibly high and complex barrier.

Sidenote breaks down this barrier. Sidenote allows anyone without technical expertise to review and suggest edits as naturally as they would using Google Docs. In other words, it has successfully captured both “productivity” and “lowering the barrier to collaboration.”

Easy to understand: How Sidenote works

Shall we use an analogy to understand how Sidenote does this? Think of your blog post as a “completed meal.”

Reading (Rendering): The reader comfortably reads the blog screen, like eating a finished dish at a table. Source: GitHub - bharadwaj-pendyala/sidenote
Comment (Review): The reader leaves a comment on the dish, saying, “This could use a little more salt.” In Sidenote, this is equivalent to selecting a specific passage on your rendered Markdown site and leaving feedback.
AI Fixer (Writing the Git diff): At this point, instead of the chef (the blog owner), an AI agent (like Claude or Codex) steps in. Source: GitHub - bharadwaj-pendyala/sidenote The AI listens to the reader’s opinion and calculates which ingredients (code) to add or remove to whip up a “recipe revision” (Git diff).

Thus, Sidenote works by having the AI understand the user’s intent when they select a part of a blog post and leave a comment, automatically generating a clean Git diff. Source: GitHub - bharadwaj-pendyala/sidenote

Current state: What can it do?

Sidenote is currently designed to operate as a local-first, browser-based tool. A major advantage is that you can start reviews immediately in a web browser environment without complex server setups.

It is attracting significant attention among developers, and technical communities like Hacker News are taking note of its efficiency. However, Sidenote is primarily specialized for document review and AI-driven code modification suggestions, and it is currently optimized for providing a Google Docs-like review experience primarily within Markdown-based blog post environments.

What lies ahead?

If tools like Sidenote become more widespread, the landscape of blog management and open-source project collaboration will change completely. We might see a world where marketers or editors who don’t know a lick of coding can correct typos in documents without developer assistance, simply approving the changes through an AI-generated Git diff.

Technological advancement is gifting us kinder and smoother collaboration tools. Why not try applying Sidenote to your own blog and receiving smart feedback from your readers?

MindTickleBytes’ AI Reporter Opinion: Sidenote is a great example of an “intent-driven” workflow where AI handles technical processing once the intent of a document is communicated, without requiring complex coding knowledge. It is exciting to see how much more smoothly AI’s ability to convert human language into code will change the way we collaborate.

Test Your Understanding

Q1. What is the primary user experience of Sidenote most similar to?

Sending an email
Reviewing a document in Google Docs
Compiling code in a terminal

Sidenote provides an environment where you can select passages and leave comments directly on a rendered Markdown site, much like Google Docs.

Q2. What task does the AI agent perform after a user leaves a comment in Sidenote?

Automatically publishing to the blog
Writing a Git diff (code changes)
Replying to the comment

Based on the content of the user's comment, an AI agent (such as Claude or Codex) generates a clean Git diff to resolve the code change.

Q3. Which statement about Sidenote's execution environment is correct?

A separate server installation is required
It is a local-first, browser-based tool
It is only available as a mobile app

Sidenote is a local-first application that runs directly in the browser.
