What's inside

Everything you need to specify a product.

From early discovery to engineering handoff, Xpec keeps your business, UX, and design system specs aligned in one place.

Business specifications

Vision, target users, value proposition, capabilities, and MVP scope — drafted from your inputs in a structured editable format.

UX specifications

User personas, journeys, screen inventories, interaction principles, and accessibility expectations — wired to the same source context.

Design system specifications

Color, typography, spacing, components, and patterns documented as design tokens — exportable as Markdown or implementation-ready files.

Reference library

Store reference products, screenshots, and competitor notes separately. Toggle which sources feed each generation.

Reviewable AI diffs

AI never silently overwrites your work. Every regeneration shows up as a proposal you can accept, edit, or discard.

Reliable export

Markdown, PDF, ZIP, or direct push to GitHub. Headings, tables, and structure preserved every time.

AI-assisted generation

Generate complete spec sets, not just paragraphs.

Pick the spec types you need. Xpec reads your reference material, drafts each document with the right structure, and surfaces open questions for the things it can't infer.

  • Generate business, UX, and design specs in parallel
  • Streaming progress per document and section
  • Open questions surface what the AI couldn't decide
  • Drafts always start in Needs review state

Reference library

Source material, kept distinct from your specs.

Drop in Markdown files, screenshots, competitor notes, or paste a link. Reference material stays visually separate from your active specs — and you control which sources inform each generation.

  • Markdown, PDF, image, link, and plain note inputs
  • Source labels keep references out of your final docs
  • Per-generation source toggles
  • Comparison view: what's inherited vs. what's new

Adapting an existing product? Xpec maps positioning, target users, capabilities, and design decisions side-by-side — so the things you intentionally diverged on don't get lost in the noise.

  • Positioning, users, and feature mapping
  • Persona and UX pattern adaptation
  • Design system inheritance vs. divergence
  • Gaps and assumptions surfaced explicitly

How it works

From rough idea to ready-to-build,
in four passes.

A predictable workflow that scales from solo founders to product teams.

01

Add context

Drop in reference material — Markdown, screenshots, notes, links. Or start from a one-line idea.

02

Generate

Pick the spec types you need. Xpec drafts them in parallel and flags open questions.

03

Review

Edit in Markdown. Regenerate sections as reviewable proposals. Resolve open questions inline.

04

Export

Send clean Markdown, PDF, or ZIP to design and engineering. Or push to your GitHub repo.

We replaced three separate Notion templates and a folder of half-finished Google Docs with one Xpec product per product. Our handoffs to engineering finally make sense.

FAQ

Questions, answered.

No. Products are private by default and your reference material is never used to train shared models. Pro and Team plans include explicit AI training opt-out, and Enterprise customers can run in a private isolated tenancy.
Yes — Markdown imports work out of the box, and we offer a Notion connector on Pro and above. Imported documents land in your reference library, distinct from your new specs.
Every AI action — initial generation, section regeneration, rewriting — produces a proposal, not an automatic write. You see a diff, you accept or discard. Xpec will never silently overwrite content you've edited.
Yes. The Free plan includes 2 product products, 15 AI generations per month, and Markdown export. No credit card required.
Always. All your specs, reference material, and version history can be exported as Markdown or a full ZIP at any time, on any plan, including Free.
