Hubs
Structured landing pages that connect tools, samples, and workflows around one theme.
Calculators, numerics, date logic, statistics, and finance tools
Image, audio, and video processing, conversion, and optimization tools
Color, layout, graphics, visual styling, and design helper tools
Writing, cleanup, formatting, extraction, and text analysis tools
Developer utilities, networking, web debugging, and automation helpers
Format, file, archive, unit, and encoding conversion tools
Balance multiple audio sources, place timed layers, smooth handoffs with crossfades, and verify a clean, non-clipping result by listening and checking peaks.
Preview source clips, create precise silence, and make restrained character effects for editing or prototyping.
Create a durable audio identity record with loudness, silence, and preview evidence for QC or cataloging.
Define and test product-owned password and color-code rules while separating application allowlists and ranges from generic validator results.
Build repeatable mock payloads, generate format-valid edge values, catch confusing field names, and review a temporary mock service before sharing it with a development team.
Generate a test signing key, inspect AGEX bundle metadata, verify its signature with a trusted public key, and stop the handoff when evidence is incomplete.
Shift songs into a comfortable key, find vocal range, generate tuning references, extract melody and chords, build tempo drills, add swing, and practice pronunciation with repeatable browser audio tools.
Find clean loop seams, generate or extend ambience, align musical timing, and finish repeatable audio beds with fades, crossfades, and tempo-synced motion.
Plan an A/B experiment, size its evidence, select the right test, and review effect size and uncertainty before treating a result as actionable.
Solve engineering math problems across ODEs, Laplace or Z transforms, convolution, and numerical approximation while checking method fit, units, and initial conditions.
Correct exposure and color in video, add a restrained LUT or filter look, and handle interlacing or HDR/SDR delivery separately.
Prepare narration takes, proofread against the manuscript, repair breaths and room tone, choose strong reads, and export ACX-aware audiobook or voiceover segments in your browser.
