Use case
Keep a requirements doc that is still true next month
Most requirements docs are accurate for about a week. Then something changes on a call, everyone agrees to it verbally, and the document quietly becomes a record of what you all used to think. Spectr keeps it as a living, versioned document instead - built from your meetings, updated when scope moves, and tagged at the moments you will need to point back to.
An out-of-date requirements doc is worse than not having one
Nobody decides to let the doc rot. It happens because updating it is a separate unpaid job that loses to delivery every week, and because the changes arrive verbally - in a call, in a Slack thread, in a decision nobody wrote down. Then people stop trusting it. Once they stop trusting it they stop reading it, and the one thing that could have settled a scope argument is the thing nobody cites.
What it actually looks like
Month two of a fixed-fee build. Scope has moved three times and the signed doc has not.
Week 1
You generate the requirements doc from the two discovery calls. It comes back as a real document - headings, tables, the lot. You fix a few things and tag it as the agreed version.
Week 3
A call changes how reporting works. You import the call and ask Spectr to update the doc. It rewrites the affected sections and leaves the rest alone.
Week 3
You read the diff, agree with it, and tag a new version. The old one is still there.
Week 6
The client says the export was always supposed to include archived records. You open the tagged version from week 3. It says, in writing, that it was not.
Week 6
That is a change order conversation instead of an argument. It takes ten minutes and nobody gets defensive.
Week 7
You generate a spec sheet straight from the agreed doc - no meeting needed - and the stories that come out are traceable to that exact version.
An afternoon of rewriting a document nobody trusts has turned into a few minutes per change - and a week-six scope argument has turned into a ten-minute change order.
Versions you can actually point at
Every revision is a version. Tag one when scope is agreed and it becomes the reference point - the thing you open when someone remembers the requirement differently. Drafts carry on top of it without disturbing what was tagged.
Written and updated from real sources
Start a document from a meeting, from pasted text, or from an uploaded file. When something changes, ask for an update in plain language and Spectr rewrites the sections it affects. This runs on the most capable model Spectr uses, because rewriting a whole document is where reasoning quality shows up most.
It looks like a document, because a client will read it
The editor is a proper rich-text one - headings, lists, tables, code blocks. It exports to PDF with the structure intact and code still highlighted. Nobody has to open a markdown file to understand what they agreed to.
Straight from the doc to a backlog
Once a requirements doc is agreed, generate a spec sheet directly from it. No meeting required. Spectr links the new spec to that requirement version, so the stories can be traced to the document they came from rather than to somebody's memory of a call.

Frequently asked questions
What is the difference between a requirements doc and a spec sheet here?
The requirements doc is the agreed scope, written as prose and versioned over the life of the project. A spec sheet is the output of one run - requirements, bugs, decisions and action items, with draft stories attached.
Can I use this for a BRD as well as a PRD?
Yes. They are the same versioned document type. What differs is what you put in it and who it is for. There is a plain explanation of both in the glossary.
Does generating a spec from a requirement re-read all my integrations?
No, and that is deliberate. The requirements doc is already the agreed, tidied version of that context, so re-reading everything would only add noise.
Can I share the doc with a client?
Export it to PDF. There is no client-facing portal today.
