It has an English interface and account-based sync. Feedback on the actual daily workflow is welcome. https://my-daily-life.pages.dev/en/ https://my-daily-life.pages.dev/en/ I built a free browser-only CSV merge tool for mismatched headers. Map 'Customer Name' and 'Full Name' to 'Name', choose a deduplication key, preview the merged rows, and download a spreadsheet-friendly CSV. Your files stay in the browser. I'd appreciate feedback from people who routinely clean spreadsheet exports. https://tb-csv-merge-studio.pages.dev/en/ https://tb-csv-merge-studio.pages.dev/en/ I built a small browser-only manuscript checker for writers. Paste a draft to find repeated English words, long lines and paragraphs, dialogue-leading lines, and matching phrases. Your text never leaves the browser. This isn't a grammar or AI-prose evaluator; it helps flag passages worth reviewing. https://tb-manuscript-lens.pages.dev/en/ https://tb-manuscript-lens.pages.dev/en/ I made a free browser-based planning tool for serial fiction writers: keep episode notes, character debuts, and planted/paid-off plot threads in one place. It highlights unresolved foreshadowing and exports a JSON backup. I'd love practical feedback from writers working on a serial novel. https://tb-novel-planner.pages.dev/en/ https://tb-novel-planner.pages.dev/en/
