Built by a product engineer in Split, Croatia, Plain Markdown is a browser extension that strips any webpage down to clean, readable markdown - ready for an LLM, Obsidian, Notion, or Readwise in a single click.
Petar is a 44-year-old product engineer based in Split, Croatia. His days run on a rhythm of client calls, research sessions, family, and gardening. During the research parts, he kept running into the same small friction: he was already on a webpage, he needed its content in an LLM, and every path there was messier than it needed to be.
Pasting a URL into Claude or ChatGPT works sometimes. But Cloudflare blocks, heavy JavaScript pages, and social media walls make it unreliable. And when it does work, the response often comes back bloated - full of navigation chrome, ads, and sidebar noise that burns tokens and muddies the actual content. Petar wanted a single click, taken from the page he was already reading, that returned just the signal.
He looked at what existed. The options fell into two camps: tight integrations built for specific platforms like Obsidian or Notion that often struggled with real-world pages, and general markdown converters with UX rough enough to make the whole process feel like more work than it saved. Neither fit.
So he built Plain Markdown.
Capture, Act, Send
The extension follows a three-step loop. First, it captures: one click converts the current page into clean, rendered markdown, stripped of ads, menus, and everything else that is not the actual content. Second, it acts: users can run any AI prompt directly on the captured markdown without leaving the extension. Third, it sends: the result lands in Obsidian, Notion, Readwise, or any other connected destination.
All of this happens in the browser. Plain Markdown does not collect email addresses, does not store page content on a server, and does not require an account unless a user chooses to upgrade. The processing stays local.
The extension has reached 638 active users since launch and reached the top spot on Uneed. Pricing keeps the barrier low: a free tier with 30 AI actions per month, a Pro plan at $29 per year for 3,000 actions, and a one-time BYOK Lifetime option at $19 for users who want to bring their own OpenRouter key and access more than 340 models.
Petar is currently focused on improving image URL handling, extending destination support with custom webhooks, and building workflow shortcuts that combine an AI action and a destination into a single click. A Firefox version is also in the roadmap.
PlainMarkdown is available now for Chrome and Brave at the Chrome Web Store.
