Leetion

Leetion is a Chrome extension for saving LeetCode problems, solutions, and notes into a Notion database. It is aimed at people who track their LeetCode progress in Notion and want that material captured with one click rather than manual copy-pasting.

Its core functions center on automatic capture and organization. Leetion automatically extracts the problem title, number, difficulty, code, and language from LeetCode, and it can detect problem tags while also letting users add custom tags, expertise levels, and alternative methods. The extension supports saving solutions in different languages separately, so both versions remain preserved when switching between languages such as Python and Java. It also includes spaced repetition, which automatically sets review dates based on user preferences, and a drawing canvas for sketches and visual notes that can be saved to the downloads folder. Notes can be written with markdown formatting, including headings, bullet points, bold, and italic text, and then synced to Notion.

The product is delivered as a Chrome extension and is installed from the Chrome Web Store. Setup involves creating a Notion integration, duplicating a Notion template, sharing it with the integration, and entering a database ID and API key in the extension. The page also links to GitHub and describes the workflow as syncing LeetCode content to a Notion database with one click.

Leetion is described as 100% free forever. The page also states that it is created by Neel Bansal and that any code contributed becomes the property of Leetion, while the contributor’s effort is recognized.
