Cygnus - World-class AI for real professional work

by•
Cygnus is an AI assistant for professionals, not just chat. It researches from real sources, reasons across 14 fields (law, medicine, engineering, science, economics…), and produces ready-to-use documents — Word, PowerPoint, Excel, PDF. Free to start; White Swan (fast) & Black Swan (deepest reasoning) paid tiers; OpenAI-compatible API; and a marketplace of verified professionals. Frontier-class quality at a fraction of the price.

Hi PH! I built Cygnus because most AI tools stop at chat. Cygnus does the actual professional work — it researches from real sources, reasons across 14 fields, and hands you a finished document (Word, PPT, Excel, PDF). There's a free tier to try, two paid tiers for heavier work, and an OpenAI-compatible API for developers. Would love your feedback — ask me anything!

real document output is a huge time-saver, especially the Word and PowerPoint exports. Curious how the Black Swan tier handles long legal memos before I commit past the free plan.
