Straight answers. No software fog.

A confirmed list of use cases, structured requirements, screen specifications (fields, actions, business rules), process-flow diagrams, a clickable HTML prototype per use case, and QA test cases for each use case, all exportable to Word or Markdown. In a managed build engagement, we also deliver the tested application, technical documentation, help, training and handover.

Both, clearly separated. The platform lets your team run the first three stages — Understand, Specify and Challenge — for $49 per seat. Managed engagements (BuildAI, BidWin) use the complete six-stage pipeline, with our team accountable for the finished outcome and you approving every gate.

No. Brieful interviews you with focused questions and writes the structured requirements from your answers. A live coverage meter shows when the essentials are covered, so you know when you're done instead of guessing. You review and edit, but you never start from a blank page.

Yes. Upload a requirements doc, gap analysis, solicitation or notes (PDF, Word, or text) and Brieful extracts the use cases and existing requirements before the interview. If your document only describes a problem, add a one-line build goal and Brieful proposes the system that solves it.

Yes. When you start a project you choose a scope: Presales demo for a fast, convincing walkthrough with the fewest questions, MVP for a core build, or Full spec for a complete, build-ready document. Brieful tunes how deep the interview goes to match, and you can change scope anytime.

Open a prototype in Present mode. It highlights exactly what's clickable on each screen and shows a 'next steps' bar of where every screen leads, drawn from the prototype's own flow, so navigating a live demo is effortless. You can also download any prototype as a standalone HTML file.

The platform gives you the package an RFP is built from: a structured requirements document, scoped use cases, and a clickable prototype — used both to author RFPs and to respond to them. Writing the bid itself is a service, not something you do in the platform: BidWin is run by our team and covers the compliance matrix against the solicitation, a drafted and red-teamed proposal with architecture diagrams, a price sheet, and a working demo the panel can click. Tell us about the bid from the contact page.

Yes. For each use case it generates traceable QA test cases (happy path, negative, edge, and role/permission scenarios) in step-based or Gherkin format, linked to the requirements they verify. Export them to CSV for Jira/Xray, TestRail, or Azure DevOps, or include them in the requirements document.

Each pack is labelled by trust level. 'Expert-verified' packs have been reviewed by a person; 'AI-generated · beta' packs are drafted by advanced AI as a fast starting point and are not yet independently validated by a subject-matter expert. Both are clearly marked when you pick one, and every suggestion a pack contributes is something you confirm or edit — so you stay in control. Treat AI-generated packs (especially any compliance or regulatory points) as a head start to verify, not the final word.

Yes. Every project has a History panel with an activity timeline of what changed and who changed it, plus Baselines — named snapshots of your requirements. Freeze a baseline for client sign-off, compare it against the live project to see exactly what's been added, removed, or changed since, and restore any snapshot. Restores are reversible: your current version is auto-saved as a baseline first.

A full requirements document as Word (.docx) or Markdown, with screen tables, flow diagrams, and test cases embedded. Test cases also export to CSV for test-management tools. Prototypes download as standalone HTML files.

Yes. Projects persist. You can add use cases at any time and continue across multiple sessions, picking up exactly where you left off.

Yes. Create a shared workspace and invite teammates by email. Everyone can work on the same projects, with roles (owner, admin, member) controlling who manages the team and billing. Live presence shows who's viewing, concurrent edits are protected so no one overwrites anyone's work, and the design library is shared across the team.

Yes — that's BuildAI. Bring an existing project, a brief, or a system you've outgrown and we analyze it, agree the scope, and build the working system: specification, prototypes, QA test cases, technical documentation, training material and handover. If you're responding to an RFP, we can build the solution alongside the proposal so you submit a working demo rather than a description of one. Work is scoped in phases, you approve at every gate, and everything is exportable and yours.

In six gated stages: we map your operation and you confirm the scope; every use case becomes a clickable prototype you sign off; an independent review challenges the spec and you answer its clarifications; if you're bidding, the proposal is drafted and red-teamed; the build is executed against acceptance tests; and the delivered system ships with its training, help, and change process. Nothing moves past a gate without your approval — see How we deliver for the full picture.

Yes — your technology decision drives the build kit, not the other way around. The pipeline is stack-agnostic: recent deliveries alone span .NET on MS SQL, .NET on a Progress database, and Next.js on Postgres, and the same approach applies to the stack, hosting, security, accessibility and procurement constraints your standards require.

Brieful is $49 per seat per month. Before that there's a free trial — no card needed — that lets you run the whole workflow once, end to end: one project, up to 30 requirements, one clickable prototype and one set of test cases. Nothing you build in the trial is ever removed or locked; you keep it, can keep editing and exporting it, and simply can't add more until you upgrade. Every feature is switched on in both — they differ only by the monthly AI-usage allowance. Brieful is the only subscription: BidWin (we run your bid) and BuildAI (we build the system) are service engagements, scoped and quoted per bid or per project — get in touch and we'll scope it.

Nothing is locked — generation simply pauses until your next billing cycle. On a paid plan, an owner or admin can keep going by buying a credit pack ($25, $50, $100 or $200) from Billing; it's charged once to your card and available immediately. Purchased credits never expire and are used only after your monthly allowance, so nothing you pay for is wasted.

Yes, from Billing in your workspace. Cancelling stops future renewals and you keep access until the end of the period you've already paid for. All fees are non-refundable, including unused time — see the Terms for the full policy.

Engagements are scoped per project, in phases, against the requirements you approve — not per head per month. Tell us what you need from the contact page and we'll come back with an approach and a number, typically within one business day.

Your documents and projects are tied to your account and visible only to you (and an administrator for support). We don't sell your data. Prototypes run in a sandboxed frame in your browser.

AI drafts and challenges; people approve and remain accountable. Every stage has a review gate, source material stays traceable, assumptions are surfaced rather than silently adopted, and open blockers stop progression. It's a powerful first draft and thinking partner — you stay in control, reviewing and refining everything before it ships.

You do. The requirements, prototypes, test cases, documentation, and the application code are yours, exportable at every stage. There is no proprietary runtime you have to keep paying for.

Your content is never used to train AI models, project work happens in an isolated workspace, and demonstrations use fictional data only. See the privacy policy for the specifics; a DPA is available on request.
