Preview a Past Prompt as Rendered Markdown
Hover a dot in the Conversation message rail and that message opens beside it rendered as markdown — headings, numbered steps and inline code laid out — instead of one clipped line of raw text. Click the dot to jump to the message.

Why You Need This
How this feature boosts your daily productivity
The message rail exists so you can get back to something you said earlier without scrolling the whole transcript, but a clipped single line of raw text only tells you a message exists, not whether it is the one you want. For the messages worth going back to — a long brief, a numbered spec, a JSON paste — the first line is the least distinctive part, so you end up clicking through several dots to find the right one, and each miss scrolls you away from where you were. Rendering the preview as markdown makes the shape of the message visible: a spec looks like a spec, a checklist looks like a checklist, code looks like code. Recognising it becomes a hover rather than a hunt. The preview flips to the other side of the rail when there is no room and stays clear of the viewport edges, so it never opens half off-screen on a narrow window.
How It Works
Get started in 4 simple steps
Find the message rail
A column of dots runs down the right edge of Conversation, one per message you sent.
Hover a dot
The message opens beside the rail rendered as markdown — headings, numbered steps and inline code laid out the way you wrote them.
Recognise it at a glance
A spec looks like a spec and a checklist looks like a checklist, so finding the right one is a hover rather than a hunt back up the transcript.
Click to jump
Clicking the dot scrolls the transcript to that message. Scrolling the rail closes the preview.

Why It Matters
The productivity impact of having ai productivity built into your workspace
Recognising A Prompt Is A Hover
Rendered markdown shows the shape of the message, so the long brief you want is obvious rather than one clipped line among several.
You Keep Your Place
Finding the right message no longer means scrolling the transcript away from where you were and clicking back.
The Distinctive Part Is Visible
Structured prompts differ in their headings and steps, not their first line — which is exactly what the preview now shows.
It Never Opens Off-Screen
The preview flips to the other side of the rail when there is no room and stays clear of the viewport edges.
