Platforms
MoneyMetric
Calculators for compound interest, loans, mortgages, salary, investing and retirement. See formulas and assumptions alongside each estimate.
CalcSphere
Math, algebra, geometry, unit conversion, physics and engineering tools, including scientific calculation, fractions, equations and Ohm’s law.
TimeGrid
World clock, time-zone converter, date and business-day calculators, Unix timestamps, countdowns, Pomodoro and interval timers.
PixelFlow
Convert JPG, PNG, WebP and AVIF; compress, resize, crop and edit images. Selected files are processed in your browser; some tools may load third-party libraries.
PaperFlux
Merge, split, rotate and inspect PDFs, extract pages or images, and create PDFs from images. Selected files are not sent to a Tolari processing endpoint; some tools may load libraries.
GenForge
Create QR codes, barcodes, passwords with browser cryptography, UUIDs, hashes, sample text and test data. Recent runs may be saved in local browser storage depending on settings.
TextMeter
Count words, characters and sentences; clean, sort, compare and format text. Browser memory and performance depend on input size and device.
DesignMatrix
Convert HEX, RGB, HSL and CMYK; check contrast, create palettes and gradients, and generate CSS for common layouts.
DevUtility
Base64, URL and HTML codecs, JSON tools, hashes, JWT inspection, UUIDs, regex, CIDR and related developer utilities. Inputs are processed in the browser.
MathPilot
Scientific calculator, fractions, equation solvers, derivatives, matrices, probability and geometry. Outputs are deterministic where the selected operation is deterministic.
AudioForge
Trim audio, adjust speed and volume, export supported formats, inspect waveforms and remove silence. Browser codec support and device memory vary.
VideoForge
Trim supported video, mute or export segments where browser APIs allow, capture frames, build contact sheets and inspect metadata. Compatibility varies by device.
SiteKit
Generate meta tags, Open Graph, Twitter cards, robots.txt, sitemap XML, structured data, hreflang, UTM links and previews.
ChoiceForge
Generate random numbers, pickers, wheels, dice, cards, teams and groups. Random tools use browser cryptography where available; verify requirements for high-stakes draws.
