work in progress: what if your design tool gave you intent adjustments

get in we're semi-autonomously making icons now
What started as a request to be able to edit text without re-generating images has, uh, escalated slightly

What models can produce with just a tiny bit of guidance is improving at a staggering pace. Of course you can pick this stuff apart, but as far as I'm concerned this is magic

using the (just-added!) graph view!
Have been excitedly using Sprint for the past couple months and there is something absolutely wild about being able to rapidly iterate on design ideas/concepts and cross-reference objects/styles/themes across projects to create cross-talk across efforts. Here I'm trying to make Concorde-themed posters for my son and hammering the models to get it ~just so!

Been working on something new: @sprintapp It’s my take on working with image and video models on a canvas, and we already have teams using it for ~all of their imagery sprint.app

ok caring about local models lasted for about 4 hours
This is GPT-6 Astra. Anything you can do on a computer, Astra can do for you. Fast.

I'd really prefer not to build this myself, yet I'd love a simple TUI style chat app (irc but in 2026) as I find the (lack of) information density in today's chat apps to be very poor sprinkle some agent stuff and bish bash bosh bet you'll have a growing product
I built myself a TUI portfolio tracker and I think I'm love 💕

If you're doing AI imagery/video, and at ~this level of output (or want to!), I'd love to have you test something I've been building -- send me a dm!
