Ouija Compiler: Talk with Dead Languages

Description and use

SEANCE is a local AI medium that answers questions about dead programming languages, delivering verified, compilable code without internet access.

Problem

Provide accurate, executable code for legacy programming languages (COBOL, Fortran, Pascal) without relying on internet or paid APIs.

Outcome

SEANCE provides accurate, executable code for legacy languages, verified by real compilers, all running locally without internet.

Workflow

• Ask a question about a dead language
• Gate filters to allowed languages
• RAG retrieves relevant reference scrolls
• Local LLM generates answer and code
• verify.py extracts code, compiles with real compiler, runs with limits
• If error, retry up to two times with updated scrolls
• Return final answer with verified code

Evidence

SEANCE is a terminal app where you talk to the ghosts of dead programming languages.

Source

the code is compiled and run with a real compiler before you see it.

Source

Everything runs locally on an 8 GB Windows laptop (WSL2, no GPU)
