Okay this isn't for everyone but what do people recommend for drawing out systems (from databases to architecture) and technical decisions before starting a project.<p>Currently I use pen & paper to start but this inevitably gets lost and becomes a pain to update as I change things. I'm also aware that for projects involving more than one person this isn't ideal.<p>JIRA/Confluence was the go-to at work with some draw.io diagrams/plugins and custom vector graphics from Inkscape/Sketch/Affinity.<p>What do you do and what do you recommend?
