One doc, every model

Pick Claude, Gemini, or GPT per request. Or fan a single prompt out to all three families and synthesize one answer. No other tool ships this.

AI streams into the doc

Responses appear character-by-character as a live textbox visible to every connected peer — not buried in a side chat panel.

Ships to Word, editably

DOCX export uses native OOXML math. Open in Word, the formulas are real LaTeX-style equations — not bitmap images.

Everything you need to research, write, and ship

One editing surface for prose, math, code, tables, citations, images, audio, and video.
