What is iLang?

iLang is the native communication protocol for AI. Not a prompt template. Not a compression tool. A structured language built from symbols already inside every LLM’s training data: brackets, pipes, arrows, key-value pairs.

Two syntaxes, one protocol:

  • Operations [] — what AI does: [READ:@SRC]=>[FMT|fmt=json]=>[OUT]
  • Declarations :: — what AI is: ::GENE{verify_first|conf:confirmed}

AI-to-AI structured communication. AI internal planning. Human-to-AI in AI’s own language.

Design Principles
  • Zero ambiguity — Structured instructions eliminate guessing. AI gets it right the first time.
  • Cross-model compatibility — Tested across ChatGPT, Claude, Gemini, DeepSeek, Kimi, Qwen and GLM. No vendor lock-in.
  • AI-to-AI handshake — Two agents learn iLang, they handshake, they collaborate. No middleware needed.
  • Behavioral DNA — Declarations define traits and anti-patterns that persist across sessions and models.
Protocol at a Glance
Component Count Purpose
Verbs 88 Core operations (READ, WRIT, FMT, FILT, DRFT, FIX, etc.)
Greek Aliases 13 Single-token shortcuts (phi=FILT, Sigma=MERGE, Omega=OUT)
Modifiers 29 core plus a 20-key media profile Output control (fmt=, lng=, ton=, sty=, whr=, path=)
Entities 25 (17 addressable, 8 role) Targets (@SRC, @DST, @PREV, @LOCAL, @GH, @NULL)
Ecosystem
  • AutoCode — You say it. AutoCode ships it. 48 skills. Code to deployment in one session. GitHub
  • Imprint — Your AI’s DNA: one skill for memory, compression, onboarding, code review, debugging, planning, progress tracking, testing, git workflow, and SEO. GitHub
  • AI See — Give AI eyes. i.ilang.ai/{url} reads any webpage.
