Dailiyo — Your everyday digital companion
Dailiyo is a free hub of online calculators, converters and short, original guides built for everyday digital life. From health and finance to productivity, image tools, and developer utilities, every tool runs entirely in your browser — nothing is uploaded, nothing is stored, and there are no sign-ups. We currently maintain 63+ tools and 7 long-form articles, all hand-written and regularly reviewed by the Dailiyo editorial team.
Each tool answers one question well: what is my BMI, how much will this loan cost, how do I convert this JSON to CSV, what is my IP. We favour calm, accurate output over flashy marketing. Use the navigation above to jump into a category, or scroll down for a quick tour of what is available.

Who Builds Dailiyo
Dailiyo is maintained by a small editorial team based in New York City, NY. Every tool we publish is built in-house, every calculation is sourced from public formulas or widely accepted clinical / financial references, and every article is reviewed before publication. We do not accept sponsored placements, paid product reviews, or guest posts. Our funding comes from non-intrusive contextual advertising only — and the editorial side of the site is kept strictly separate from advertising.
