  "description": "Lekh is a collaborative diagramming and whiteboarding app. Connect it to ChatGPT to draw diagrams from a description \u2014 flowcharts, sequence diagrams, network and cloud architecture diagrams, mind maps, ER diagrams, org charts and more \u2014 using Lekh's catalogue of over 4,600 shapes, including AWS, Azure and Google Cloud icons. ChatGPT can also read, render and explain your existing boards, edit them (including while a colleague has the board open), organise boards into folders, and share them.\n\nWho it is for: anyone with a Lekh account who wants a diagram drawn or changed by asking for it.\n\nLimitations: you need a Lekh account; boards larger than 1 MB or 50 pages cannot be opened by the connector; renders use a standard font rather than the board's own; the connector does not see edits made by others until it reads the board again.",
