Product Thinking. Made Visual.

The best product ideas start as rough sketches. Map customer journeys, sketch roadmaps, build mind maps, and brainstorm features visually — before things are structured enough for Jira.

Product work has a messy middle

Product managers do a lot of visual thinking — customer journey maps, mind maps, concept maps, roadmap sketches, feature brainstorms. But most of this happens in the 'messy middle' before things are structured enough for formal tools. PMs often resort to pen and paper, which isn't shareable, or structured tools, which are too rigid for exploration. You need something in between.

How T-Sketch Helps

Sketch user flows without rigid templates

Draw rough user journeys and flow diagrams freehand, without being constrained by flowchart templates. Mix freeform drawing with text, arrows, and annotations. Start messy, refine as clarity emerges — on an infinite canvas that keeps all your explorations visible.
