## Papers

- [Telegraph English: Semantic Prompt Compression via Structured Symbolic Rewriting](https://telegrapher.ai/research/telegraph-english.md): Rewriting text so each line holds one claim, with explicit symbols for cause and contrast, cut tokens by about two fifths and lost fewer answers than LLMLingua-2's token deletion, by the widest margin on fine details. (NeurIPS 2026 submission, May 2026)
