Plain Markdown

The AI actions feature transforms Plain Markdown from a simple converter into an intelligent assistant. Users can apply curated everyday prompts such as "summarize this article," "rewrite in simpler language," or "extract action items" directly from the side panel. For those with specific needs, the tool allows building custom AI actions using your own instructions. The underlying model for Free and Pro tiers is Google's Gemini 2.5 Flash, which provides fast and context-aware responses. Power users can opt for the BYOK Lifetime plan, which lets them bring their own OpenRouter API key to select from over 200 models across providers like Anthropic, OpenAI, and Google. This flexibility ensures that the AI actions remain useful for diverse tasks, from quick overviews to deep analysis, all without leaving the browser tab.

After capturing and optionally refining content with AI, Plain Markdown provides multiple destinations where users can send their finished Markdown. One-click transfers are available to Obsidian, Readwise Reader, and Notion, with the content arriving fully formatted and ready to integrate into existing notes or databases. Users can also copy the Markdown to the clipboard for pasting into any other application, or download the result as a .md file for offline storage. These integrations are designed to fit seamlessly into common knowledge management workflows, reducing friction between web browsing and documentation. The extension remembers user preferences for frequent destinations, making repeated actions even faster. This approach ensures that captured information flows directly into the user's primary tools without manual export steps.

Plain Markdown operates entirely within the browser ecosystem, requiring no external servers for the conversion step—page content is processed locally to maintain privacy. The extension is available for Chrome, Brave, and other Chromium-based browsers, with Firefox support planned. After installation, a toolbar icon appears; clicking it opens a side panel that shows the converted Markdown of the current page. From there, users can edit, apply AI actions, or send the content to a destination. For AI actions, the relevant page content is sent to Plain Markdown's server (or the user's chosen provider via BYOK) for processing, with no data stored afterward. This architecture balances performance and privacy, giving users confidence that their reading data is not retained unnecessarily.

Concrete use cases demonstrate the tool's versatility. A researcher loading a heavy academic article can convert it to Markdown, apply the summarization AI action to get a one-paragraph abstract, and send both the full text and summary to Obsidian for citation management. A social media analyst monitoring Reddit threads can capture multiple discussions, use the AI checklist extraction action to identify key points, and then copy the results to Notion for team reporting. A developer preparing training data for a chatbot can batch capture 50 webpages via multi-tab capture, edit each in the inline editor to remove unwanted sections, and download the cleaned Markdown files. In every scenario, the outcome is reduced manual effort, higher quality input, and faster integration into the user's workflow. Users consistently save minutes per task, which compounds across a day's work.

The target audience includes knowledge workers, students, researchers, content curators, and AI developers who frequently interact with web content. The product runs on Chromium-based browsers (Chrome, Brave, etc.) with no account needed for the free tier. Pricing is straightforward: a Free plan with 30 AI actions per month, a Pro 100× plan at $29/year for 3,000 AI actions and priority support, and a BYOK Lifetime plan for $19 once that removes action caps and allows any model via the user's own OpenRouter key. Each plan includes core capture and destination features. In summary, Plain Markdown offers an elegant, privacy-conscious solution for converting webpages to Markdown and applying AI actions, making it an indispensable tool for anyone building a knowledge base or working with large language models. Its combination of one-click simplicity and powerful AI integrations sets it apart from traditional bookmarking or clipping tools.
