SPEC Shorthand Codec (Retired Archive)

This browser-only codec demo is preserved for historical inspection. SPEC is retired and is not an active Kiah feature, SDK, API, or product.

Lossless ~-token encoding can still be decoded deterministically. Semantic mode remains lossy.

How SPEC Works

1

Lossless Codes

Dictionary words become short ~-prefixed tokens (safe to decode)

the → ~t, because → ~bc
2

Phrase Codes

Common prompt phrases compress to short codes (lossless; tokenizer-dependent)

for example → ~p/eg, in other words → ~p/iow
3

Case + Escapes

Preserve case and prevent accidental expansions

Tomorrow → ~^tmrw, ~ → ~~
4

Semantic Mode

Optional vowel compression for extra savings on long lowercase words (not perfectly reversible; skips mixed-case identifiers)

characterization → charctrztn
