Live preview — see the notch before you press play.
Split-pane HeyNotch editor with a live render that updates per keystroke.
There's no surprise the moment you press play. The right pane of the editor renders your script in real time — variables substituted, branches as banners, pauses and speed changes as inline badges.
It's the closest thing to seeing your notch performance ahead of time. Catch issues at the desk, not on the call.
Per-keystroke rendering
Type, see. No save button, no compile step.
Variables substituted
Preview replaces {{prospect_name}} with whatever default you've set.
Branches as banners
Each ## [name] block renders as a coloured banner with content nested below.
Real-world examples
Streamdown scripts you can copy.
Drop these straight into the HeyNotch editor. They're production-tested, branched, and ready to personalise with your variables.
What you write vs what you see
Source on the left, rendered preview on the right. Variables fill, branches become coloured banners, pauses become amber badges.
# Source (Streamdown)
Hi {{prospect_name}},
this is {{your_name}}.
<!-- pause:1s -->
## [Interested]
Let me show you how.
# Preview (rendered)
Hi Sarah, this is Alex.
[ ⏸ pause 1s ]
🔵 Branch: Interested
"Let me show you how."Common questions
Open preview as a separate window?
Not yet — split-pane only today. Roadmap.
Show pauses?
Yes — pause tags render as small amber badges. Speed changes as sky-blue badges.
Same as the notch?
Visually similar but not identical — preview reads top-to-bottom; the notch reads one line at a time.
HeyNotch is coming soon.
