AI Tools

Transcribe speech from audio (wav/mp3/m4a/flac/ogg/webm/aac) to text, SRT, VTT or JSON using the grok-stt AI model. Up to 10 minutes.

AI Tools

AI content-moderation classifier using NSFWJS to flag uploaded images as safe or potentially inappropriate. Built for moderation and compliance review of your own files — it analyzes uploads only and is not an image search or discovery tool. Supports JPEG/PNG/WEBP/GIF.

Text Processing

Run a portable text-cleaning recipe and inspect every step, diff, timing, and character change.

Text Processing

Encode, decode, visualize, and brute-force the Rail Fence transposition cipher. See the zigzag rail grid and try all rail counts to crack a ciphertext.

Development

Drop any game save file — Minecraft NBT, Unreal Engine GVAS, Palworld containers, JSON/XML/INI/Lua text saves, SQLite profiles — and get the detected format, engine versions, key progress fields and a bounded structural tree.

Data Processing

Paste one or two columns of numbers and get the complete descriptive suite — mean/median/mode, sample and population variance, type-7 quartiles and percentiles, MAD, adjusted skewness and kurtosis, Tukey outliers — plus covariance, Pearson r, tie-corrected Spearman rho and least-squares regression for two columns.

Media

Brighten dull vocals or masters with a high air shelf plus an exciter that synthesizes new top-end harmonics — the Aphex Aural Exciter architecture built from FFmpeg.

Media

Run audio through a simulated tape machine: tanh magnetic soft clipping, speed-dependent head bump and HF rolloff, wow & flutter, and tape hiss — with 3.75/7.5/15/30 IPS presets.

Media

Detect and dynamically attenuate harshness in the 2–5 kHz presence band — a dynamic-EQ-style cut that only bites when the band actually plays loud.

Media

Detect and reduce 150–500 Hz low-mid buildup — the stacked-fundamentals mud that turns a mix boxy — with a measured, focus-tuned parametric cut.

Compression

Upload a PNG or APNG and audit the whole animation structure: PNG signature and per-chunk CRC32 checks, IHDR bit depth / color type / interlace, acTL placement and declared frame counts, every fcTL (region bounds inside the canvas, normalized delay fractions, dispose_op none/background/previous, blend_op source/over), the shared fcTL+fdAT sequence-number contract from 0, per-frame replay of the IDAT/fdAT deflate streams with exact decompressed-size verification, and disposal-semantics audit — first-frame PREVIOUS treated as BACKGROUND, zero-delay frames, loop counts, fps and compression ratios.

Development

Validate W3C Trace Context propagation headers end to end: traceparent (version / 16-byte trace-id / 8-byte parent-id / trace-flags), tracestate (≤32 list members, tenant keys), baggage (percent-encoded values + opaque properties), OTLP export Content-Type, the gRPC grpc-trace-context-bin 25-byte binary context — plus a two-header correlation round-trip with a random child span-id collision check.
