Built by two developers who got tired of watching tokens burn. No venture backing, no tracking, no BS.
Founder of CuToken. Built the multi-pass optimization engine, the grammar guards, and the infrastructure it all runs on. Works low in the stack — C23 memory allocators, Linux kernel tuning, DevOps pipelines — and brings that same systems-level discipline to CuToken's deterministic architecture. A Linux Mint / Cinnamon advocate who mentors junior developers on memory debugging and CI/CD.
A prominent member of the CuToken team, working across the frontend and handling marketing. Developer, educator, and founder of PrepNex, PYQ Junction, and Learn With Asad in his own right, and author of The Ultimate Python Playbook. Started building in Class 6 with a summer electronics project and has since picked up an SOF IMO gold medal, an Avishkaar Robotics championship, and an IIT Bombay Techfest finals spot along the way.
Yawar started CuToken while building LLM-powered products and watching token bills climb as prompts grew increasingly verbose. Every "please note that" and "I would like to" was costing real money and eating context windows.
Existing solutions were either cloud APIs with per-token pricing, opaque SaaS platforms, or academic research code that couldn't handle production edge cases (dangling prepositions, grammar breaks, semantic meaning loss).
So we built what we needed: a deterministic, auditable optimizer that gives you a full changelog for every change and never sends your prompt data to a third-party AI provider.
Your prompt is optimized directly — no forwarding to third-party AI APIs, no external calls, no data resale. What you paste is what gets processed, nothing more.
Every change logged with type, detail, and risk weight. You see exactly what was removed, why, and the confidence score. No black box.
Real structural validation: no dangling prepositions, no doubled determiners, no modal-verb-breaks, balanced quotes/parens. If it breaks grammar, the change is reverted.
No ML inference, no GPU, no cold starts. Pure PHP string operations and regex. Sub-100ms typical. Predictable latency for production SLAs.
Free to use, no seats, no tiers, no usage limits. We make money by saving you money on your AI token bill, not by charging for the tool.
We document limitations: can't catch zero-vocabulary paraphrase, no embeddings, no external knowledge. If a pattern isn't in our maps, we don't guess—we preserve.
Spotted a phrase we should compress, a grammar edge case, or a template you'd like to see? Let us know.
