Baker's Percent

Baker's Percent is for serious home bakers who think in grams and ratios, not cups and guesswork. Open any recipe page, click the toolbar button, and a slide-in panel extracts the ingredient list, converts every line to grams, and shows baker's percentages with total flour as the 100% base. Extraction first looks for schema.org Recipe structured data (JSON-LD), which most modern recipe sites publish, and falls back to a heuristic that finds the densest ingredient-looking list on the page. The parser handles Unicode and mixed fractions, decimals, ranges ("2-3 cups" becomes the midpoint), explicit gram hints like "(120g)", baking shorthand (capital T for tablespoon, lowercase t for teaspoon), and countable eggs, yolks, and whites. Key features: - One-click analysis of the current recipe page, with a toggle to close the panel - Automatic gram conversion using a bundled density table (flour, sugars, butter, liquids, cocoa, salt, yeast, leaveners, and more) - Baker's percentages with total flour as 100%, or click any ingredient to re-base on it - Proportional rescaling: edit any gram value or type a target total dough weight, and the whole recipe rescales while ratios stay fixed - Unknown ingredients are flagged with a "?" so you can type the correct weight for just that row - Copy the result as a Markdown table, including totals and the current base What it does not do: Baker's Percent has no analytics and requires no account. It has no broad host permissions and no content scripts running by default; it only touches the page you are on, and only when you click the button. Its only network use is validating your license key with Lemon Squeezy; no page content or browsing data ever leaves your device. Density-based volume conversion is approximate by nature, so weigh your flour when precision matters. Pricing: Baker's Percent is free to install and requires a $5 one-time license, purchased through Lemon Squeezy, to activate. Enter your key once on the extension's options page. Licenses are re-checked periodically with a 7-day offline grace period, so a bad connection never locks you out.
