Product teams shipping with Quillon
Stop stitching together docs, chat threads and meeting notes. Everything about a decision lives with the spec.
Link a spec to tickets and designs. When something changes, the spec shows it, and so does everyone watching.
faster spec reviews for the average team
Every comment has an owner and a resolved state.
Issue trackers, design files, chat and calendars. Two-way sync, no copy and paste.
Pick one of 40+ spec templates, or let Quillon outline one from your ticket. Every section knows what belongs in it.
Inline suggestions, required approvers and a clear done state. No more asking whether anyone looked at it.
Every decision gets an owner, a date and a link back to the discussion that led to it.
Specs sync to your issue tracker as tickets, and the tickets update when the spec changes.
A typical Quillon spec goes from idea to engineering-ready in five working days. Here’s the path.
Paste a ticket or a rough idea. Quillon drafts the outline and flags the questions you’ll need answered.
Write together in real time. Assign sections so nobody waits on anybody else.
Required approvers sign off in the doc. Every decision gets logged with an owner and a date.
One click turns the spec into linked tickets that update if the spec changes.
How Quillon stacks up against the usual mix of shared docs, chat and a team wiki.
