Skip AI. Order Human-Written System-design Documents.
Design documents are designed for the purpose of allowing multiple people to critique one document prior to coding. This means making criticism simple: outline the constraints, label the alternatives that wouldn’t work, and state which option would make this the incorrect choice.
This response is based on your problem statement, some capacity data, and interviews with the engineers. For anything that requires a number and that one is not provided, the writer indicates that it is required input instead of providing one.
What Makes No-AI System-design Documents Easy to Follow?
Design documents are read in a specific order by reviewers: what problem, what constraints, what are we not doing, what is proposed, what breaks. A document in that format gains valuable feedback. One that starts with the solution gains comments about the shape of the solution from people who never viewed the constraint that led to that solution.
Problem and constraints stated before any proposed design.
Non-goals written down so scope arguments end early.
Rejected alternatives kept in, with the reason each lost.
Where AI falls down on system-design documents
The load-bearing content of a design document is numbers: expected traffic, storage growth, latency budget, cost at scale. A model does not have yours and will come up with numbers, and will do so with the numbers in a format that looks convincing. A reviewer who trusts one of those numbers will approve a design that will collapse.
Structure, Detail and Human Writing for No-AI System-design Documents
The writer works with the engineers to draft the constraints. They identify real binding constraints that are not preferences that only feel binding. Then, sections of the document are written in review order. Where in the design someone has applied a number that hasn’t been measured, it gets inserted as a question with a name provided.
How a system-design document gets written here
You share the problem, current system limits and any capacity or latency data.
Writer interviews the engineers and separates hard constraints from preferences.
Draft written in review order, with open questions assigned to named owners.
Technical review round, then editing and the detector and plagiarism checks.
Keeping No-AI System-design Documents Useful for the Intended Reader
Hopefully the document will retain its value a year after the decision is made. Rather than deleting everything once we’ve made a decision, we leave the reasoning and other options in the file. Once a decision is made, someone will always ask the questions the reviewers have already answered. The comments get added into other sections, rather than being added at the end.
Problem statement, constraints and explicit non-goals.
Two or three alternatives with the reason each was rejected.
Failure modes and what the system does in each.
Rollout, migration and rollback plan in sequence.
Open questions listed with an owner beside each.
What people commission system-design documents for
Internal RFCs before a large engineering commitment.
Design reviews for regulated or audited systems.
Vendor proposals requiring a written technical approach.
Postmortem-driven redesigns of an existing service.
What system-design documents cost
One rate, whatever the format: $10 per 100 words. You are paying for the writer’s time and judgement, so the price scales with the words rather than with a package tier.

Questions About Buying No-AI System-design Documents
What the piece is for, who reads it, roughly how long it should be, and anything it must include or avoid. Links to your existing material help. If you are unsure, send what you have and the writer will come back with questions.
Up to 3 days. The writer has to read around the subject before writing it, so we quote honestly rather than promising an hour. If your deadline is tighter, say so in the brief and we will tell you before you pay whether we can meet it.
That’s usually the ideal time. Composing the constraints and non-goals is a way to get disagreements out in the open. You will come up with the questions your team has been avoiding. Your design is bound to change with the document.
Your engineers do. The writer structures the argument, tests it for gaps and then writes it in a clear manner, but you make the final call. Any suggestion you find in the document was asked by your team to be recorded by us.

Wrote down the tradeoffs we argued about
We have never recorded our three architecture talks but we have now. One of the teams who take note of things and join in a session and then compile a summary of the two positions once we’ve made our decision. Saw that as a good opportunity to strengthen their practice so no longer have any new hires asking questions.

Errors were described correctly
Most writers omit error response text, or post the status codes with no surrounding context. Ours explained what they thought the caller did wrong with a short response per status. Because of this explanation, our support queue for that endpoint has gone quiet.

Grouped by symptom, not by element
I asked the guide to be assembled in a way that a frustrated customer would think. It was harder than I expected, but it came back perfectly with the answer that half of the customers try - rebooting - placed at the begining.
