Most inbox cleaners either select thousands of threads at once (Gmail then hides Mark as read) or send your mail to a server.
Gmail Mark as Read walks each list page and uses Gmail's own Mark as read control. Confirm first. Mark this page only, or walk every page until done. Stop anytime from the toolbar.
Works on Inbox, Promotions, and search results. Runs locally on mail.google.com — no message bodies uploaded.
AI Context Extractor copies the webpage you're viewing—not just its URL—into AI-ready Markdown with a single shortcut. It works on logged-in sites, SPAs, localhost, internal dashboards, and pages AI crawlers can't access. The extension extracts titles, headings, content, tables of contents, selected text, and metadata, then copies everything directly to your clipboard for ChatGPT, Claude, Gemini, or any AI assistant. Everything runs locally with no accounts, no servers, and no tracking.
Umbra brings a designer-quality dark mode to every website. Instead of harsh color inversion, it uses carefully balanced colors that are easier on the eyes. It automatically skips sites with native dark themes, reduces white flashes while pages load, and lets you customize brightness, contrast, and grayscale globally or per site. Everything runs locally—no login, no tracking, and no personal data collection.
