What this is
ARZENTIQ is an independent project. Each utility takes what you already know, does one job you can check — a calculation, a conversion, a lookup, a plan — and hands you something you can use in the next step of your work: a number, a table, a plan, a file. Everything runs in your browser; there are no accounts and no ads.
Available utilities
ARZENTIQ provides 590 utilities across 16 domains. Each domain page lists its utilities by the job they belong to, and the full catalogue can be searched by task:
- Manufacturing — 71 utilities. Material preparation, cutting, shop calculations, and the maker bench: 3D printing and resin.
- Construction — 59 utilities. Areas, quantities, and layouts for building, garden and farm work: concrete, aggregate, lumber, masonry, tile, paint, grain bins, sprayers, yields.
- Electrical — 36 utilities. Formulas for electrical and audio work: voltage drop, Ohm’s law, resistors, power factor, batteries, speaker boxes, crossovers, room acoustics.
- Automotive — 27 utilities. Geometry and arithmetic for vehicles and boats: tires and wheels, gearing and speed, engines, fuel economy and cost, propellers, hull speed, anchoring.
- Developer & Data — 91 utilities. Text and data tools that run entirely in the browser: diff and compare, format and validate, encode and decode, convert between formats — nothing is uploaded.
- IT & Networking — 33 utilities. Deterministic arithmetic for systems and network work: subnets, RAID capacity, transfer time, bitrate and file size, uptime, pixels, TCP throughput, backups.
- Design & Web — 44 utilities. Generators for web and print work that run in the browser: barcodes and QR codes, CSS shadows and gradients, colour palettes, favicons, placeholder text, tagged links.
- Business — 58 utilities. Arithmetic for running a business, with your own rates: quotes and pricing, break-even, campaign metrics, timesheets, shipping weight and pallet fit, reorder points.
- Science & Maths — 66 utilities. Textbook formulas worked in the open: statistics (sample size, confidence intervals, t-tests, z-scores), triangles, dilution and molarity, the ideal gas law, projectile motion.
- Text & Writing — 32 utilities. Generators and clean-up tools for words on a page: random names, words, numbers and picks, title case, readability, line-break and quote clean-up, Markdown ↔ HTML.
- Textiles & Sewing — 11 utilities. Fabric, yarn and quilting arithmetic for sewing, knitting and soft furnishings.
- Aviation — 12 utilities. Flight-planning arithmetic for general aviation: wind, altitude, airspeed, descent, turns and balance.
- Cooking & Baking — 13 utilities. Kitchen arithmetic: scaling recipes, cups to grams, dough and brine percentages, coffee ratios.
- Photography — 11 utilities. Camera arithmetic: depth of field, field of view, exposure and ND stops, flash, golden hour, astro and time-lapse.
- Sports — 14 utilities. Sports statistics by the official formulas: batting and pitching lines, passer rating, shooting, save percentage, standings, golf handicaps and bowling scores.
- Brewing — 12 utilities. Homebrewing arithmetic for beer, wine, mead and cider: ABV and attenuation, refractometer and hydrometer readings, mash water, IBU, colour and carbonation.
The first utility, Material Planner, turns one parts list into an estimated material weight, the number of stock bars to buy, and a straight-cut layout that accounts for saw kerf and end trim; every utility since has followed the same rule — one job, one page, a result you can check. We maintain the tools around the work they support and publish their methods and limits so you can check how each result was produced — see How we verify.
What it is not
No utility replaces the source you are accountable to. Every page states its method, its data and that data's review status, and its limits. A weight calculator uses ideal section geometry and handbook formulas; a construction estimator applies the waste, coverage and rates you enter, never a building-code value; a statistics page names its test and its assumptions. None of that replaces supplier data, engineering review, a licensed standard, or your own check before you cut, bend, buy, or sign.
Open-source components
Almost every utility is written in-house. The exception is the PDF tools (merge, split, rotate, compress), which read and write files with pdf-lib (MIT licence, © Andrew Dillon), downloaded to your browser only when you choose a file. The file itself still never leaves your device.
Tell us what is missing
The most useful thing you can do is try it on a real job and write to feedback@arzentiq.com: what you were preparing, what looked wrong, and what would have to change for you to use it again. Please do not send customer data or drawings.
How we handle the little data involved is described on the privacy page.
