// Features

One workspace from first draft to final call

Stop stitching together docs, chat threads and meeting notes. Everything about a decision lives with the spec.

01 · WRITE

Specs that stay in sync with the work

Link a spec to tickets and designs. When something changes, the spec shows it, and so does everyone watching.

// Every stage

Built for the whole life of a spec

Start from a template, not a blank page

Pick one of 40+ spec templates, or let Quillon outline one from your ticket. Every section knows what belongs in it.

Reviews that finish in one pass

Inline suggestions, required approvers and a clear done state. No more asking whether anyone looked at it.

Decisions you can find in six months

Every decision gets an owner, a date and a link back to the discussion that led to it.

Hand off without the handoff meeting

Specs sync to your issue tracker as tickets, and the tickets update when the spec changes.

// Workflow

Blank page to shipped in a week

A typical Quillon spec goes from idea to engineering-ready in five working days. Here’s the path.

D1

Outline from the ticket

Paste a ticket or a rough idea. Quillon drafts the outline and flags the questions you’ll need answered.

D2

Draft with your team

Write together in real time. Assign sections so nobody waits on anybody else.

D4

Review and decide

Required approvers sign off in the doc. Every decision gets logged with an owner and a date.

D5

Hand off to engineering

One click turns the spec into linked tickets that update if the spec changes.
