before you build.

The brief

What you walk away with

Every brief answers the questions you can’t Google — about your customer, your market, and whether to build at all.

01
Whether to build.
Verdict
A clear verdict — build, wait, or kill — with the reasoning and the one test that settles it.
02
What your customer actually wants.
The argument
Their real pains, ranked, in their own words — not your assumptions.
03
How big, and what they'll pay.
Market
The market sized from the ground up, with willingness-to-pay drawn from real signals.
04
Who feels it, and how to position.
Playbook
The customer voices behind each pain — quoted and linked to the public post — and ranked positioning angles drawn from the evidence.
05
Proof you can stand behind.
Evidence
Every figure traced to a verbatim quote and a link. Nothing invented.

Delivered as a full set of documents — a one-pager, a decision brief, and the evidence behind it — as a single PDF and a reader you can browse.

Yours alone

Paid briefs deliver to you and you alone. No team access, no shared dashboard, no opt-in you didn't ask for.

Yours to delete

Encrypted at rest. Delete your inputs and brief at any time. No questions, no retention quirks, no archive copy.

What founders ask before they buy a brief.

Still curious?

hello@briff.ai

ChatGPT will confidently invent customers, quotes, and sources. Briff actually reads what your customers wrote — every quote in your brief is a real verbatim quote with a clickable Reddit, Hacker News, or IndieHackers URL. We don't make things up; we synthesize what's already there.

Also: ChatGPT can't tell you when not to build. We will.

Then we don't think you should build this, and we'll explain why with specific evidence from the corpus. You keep the verdict — no payment, no signup. Most founders find a KILL verdict more valuable than a BUILD one, because it saves them six months of work on the wrong thing.

If you disagree, the verdict will tell you exactly which inputs (your time horizon, your runway, your constraints) drove it. Change the inputs, change the verdict.

Promised: under twenty-four hours. Typical: under one hour. The 24-hour SLA exists because some briefs need more careful synthesis or hit longer scrape windows. Most don't.

Yes. 100% refund within 7 days on one-time purchases, as long as you haven't redeemed all your briefs. Subscriptions: cancel any time, no refund on the current month, but you keep the credits already issued for that cycle.

We also won't deliver a brief that fails our nine-point quality check. Failed briefs are regenerated at our cost — you never see broken output.

No. Briff only reads public-internet content — Reddit, Hacker News, IndieHackers, public forums, public newsletters. We don't have access to paywalled Substacks, private Slack groups, or invite-only Discord servers. If your persona only talks in private spaces, briff isn't the right tool.

Only you. The agent reads your inputs, generates the brief, and delivers it to you alone — no one at briff ever sees what you submit or what comes back.

Nothing you submit is ever published or shared. Your idea, your persona, and your brief stay private, encrypted at rest, and yours to delete at any time.

Your account stays open and your past briefs stay accessible. To generate a new one, buy more credits at any tier — or start a $500 / month subscription.

Before you write a line of code

Don’t build the wrong thing.

Commission a brief and we’ll read your customers’ actual conversations — their pain points, the voices behind them, what they’ll pay, and a clear verdict on whether to build at all.
