Interface walkthrough · Companion to the build document

What it looks like

Every screen a reader meets, in the order they meet it — free brief, email, the moment they hit the wall, and the two tools they pay for. Built as an instrument, not a magazine.

Surfaces  Web · Email · iOS/Android Status  Design direction Date  5 Sept 2026

01Design principles

Five rules govern every screen. Each exists because breaking it would undermine the thing we are actually selling, which is verified judgement.

1 · Provenance is always visible

Every claim carries its tier, its corroboration count and its gate status, on the surface, in the reader's eye-line. Not hidden behind a tooltip. The reader must be able to audit us at a glance — that is the entire trust proposition, and burying it would be self-defeating.

2 · Judgement is typographically distinct from fact

Facts are set in the body serif. Why it matters sits in an amber-railed block. The reader always knows which sentences are the record and which are our opinion. Blurring the two is what makes AI content untrustworthy; keeping them visibly separate is the fix.

3 · Amber means judgement or action, nothing else

The single accent is spent only on our opinion and on the things a reader can do. It is never decorative. When the eye catches amber, it has found either a position we are taking or a button.

4 · Memory is shown, not claimed

Archive callbacks — this supersedes what was reported in March — are rendered as first-class interface elements with dates and claim IDs, not as prose asides. This is the feature no competitor has and it should look like a feature.

5 · Reading is free; everything else is paid

No truncated items, no "read more" teases, no blur-and-upgrade. The brief, item detail, archive and company pages are whole and free on web and app. The wall sits where the reader wants the brief brought to them — email, WhatsApp, Telegram — or wants to act: generate a post, query the archive. Reach is the business model; convenience and action are the products.

The design decision behind the look

Dark ground with a serif body is a deliberate pairing. The dark reads as instrument, terminal, working tool — this is a thing you consult, not a thing you browse. The serif reads as editorial judgement, which is what separates us from an aggregator.

Monospace carries everything machine-generated: claim IDs, tiers, dates, provenance. So the typeface itself tells the reader what kind of statement they are looking at, before they read a word.

02The system

Six colours, three typefaces. Deliberately tight — a constrained palette is what makes provenance chips legible at 9px.

Battery share holds; Europe's charging build slows

Two things moved this week and one did not. The duopoly in cells is unchanged despite three announcements suggesting otherwise — and the quiet story is European charging deployment falling behind its own 2026 targets for a second consecutive quarter.

01

CATL holds 39.9% of global battery share while BYD slips to 14.4%

H1 2026 installation data puts CATL roughly flat against the 40.2% recorded through May. BYD fell from 16.7% across the comparable 2025 period — the wider of the two moves.

Why it mattersTogether they hold 54.3% of global installations. For any cell buyer outside China, 2027 negotiating leverage is being set by a duopoly whose combined share has not loosened in eighteen months. BYD's decline is share moving to Korean and second-tier Chinese suppliers — not to non-Chinese capacity.

Chat channels get the summary, not the whole edition. Nobody reads eleven items in WhatsApp. The push carries the day's synthesis paragraph and the headline list with contradiction flags intact — then links out. The judgement blocks live on web where there is room for them.

WhatsApp is not "email but different"

It runs on the WhatsApp Business API: verified business account, pre-approved message templates for anything outside a 24-hour user-initiated window, and a per-conversation charge. A daily 08:00 push is exactly the template-and-charge case.

Telegram has none of those constraints — a bot, users opt in by starting a chat, no per-message cost. Ship Telegram first, and run WhatsApp approval in parallel so it lands when the audience is big enough to justify the per-message line.

06The paywall moment

This is the most commercially important screen in the product, and the one most easily got wrong. It appears only when a reader tries to act — never while they are reading.

Post this in your own voice

We'll draft it from the verified record — sources, numbers and dates intact — in the way you actually write. Sign in with LinkedIn so we know whose voice to use.

Continue with LinkedIn Use work email
THE BRIEF, ARCHIVE AND COMPANY PAGES STAY FREE — ALWAYS

What this screen does not say: no "unlock", no "premium", no blurred content behind it. The reader has finished reading — nothing was withheld. The ask is framed as whose voice to use, which is a genuine product requirement, not a pretext. That is why it converts and why it does not feel like a wall.

Three jobs, one screen

This single moment is simultaneously the qualification mechanism (we learn who they are), the personalisation input (voice needs the profile), and the liability control (we do not hand anonymous users a content generator). Every one of those is a real reason, which is why the ask is honest.

07Sign-up — 40 seconds

The whole flow, in four steps. Nothing is asked that does not either improve the output or qualify the lead.

01

Continue with LinkedIn

One click. Pulls name, headline, company and role. Also gives us the writing sample — recent posts train the voice model, which is why LinkedIn is the primary path rather than email.

02

Confirm your company

Pre-filled from LinkedIn, editable. The company website is resolved against the entity table — we now know if they are an OEM, supplier, charging operator, fund or consultancy, which drives item relevance and, later, the Atriqa prospect ranking.

03

Pick what you follow

Geographies and segments. Optional, skippable, changes the ordering of the brief but never hides items. Nobody gets a filter bubble — the whole point is knowing what the industry is doing, not what you already care about.

04

Voice check

We show three draft openings in different registers, they pick the one that sounds like them. Forty seconds, and it does more for output quality than any amount of prompt engineering.

What we deliberately never ask

No phone number. No job title free-text. No "how did you hear about us". No credit card at sign-up. Every additional field costs conversion, and we already have everything we need for both personalisation and qualification from steps 1 and 2.

YOUR VOICE ANALYTICAL CONTRARIAN SHORT
54.3%. That's CATL and BYD's combined share of global battery installations in H1. Eighteen months of people telling me the duopoly is loosening, and the number has barely moved. What did move: BYD is down to 14.4% from 16.7%. But that share didn't go to European or American capacity — it went to Korean suppliers and second-tier Chinese cells. If you're negotiating 2027 supply outside China, that distinction is the whole conversation.
Copy for LinkedIn Regenerate Add source links

The architectural boundary is visible here. The left pane shows our synthesised claim — never the source article's text. The generator has no access to publisher prose, so the reader's post cannot accidentally paraphrase a copyrighted article. The legal firewall from §03 of the build document is a literal UI division.

Why the source pane is always open

The writer is about to publish a number under their own name. Making them look at the provenance while they edit is a deliberate friction — it is the difference between a tool that helps people post accurately and one that helps them post confidently wrong.

09Ask agent

The second paid tool, and the one with the real moat. It narrates the record — it does not answer from model knowledge.

App · AskRetrieval over the claim store · citations enforced
What has BYD said about European manufacturing over the last 18 months?
Ask

Three distinct positions, and they have shifted.

In March 2025 BYD confirmed the Hungary plant with a stated 2026 start1. By January 2026 that had moved to "phased through 2027" — the change was not announced directly; it surfaced in a supplier briefing2. Most recently, July 2026, a second European site was described as "under evaluation", with no country named3.

The pattern worth noting: each statement has been less specific than the one before it. No date has been formally withdrawn, but none has been reconfirmed either.

[1] CLM-0891 · Tier A company release · 14 Mar 2025 · stated
[2] CLM-3122 · Tier B Automotive News · 22 Jan 2026 · reported
[3] CLM-4310 · Tier B Electrive · 9 Jul 2026 · reported

Every factual sentence carries a citation. An uncited assertion is a bug, not a stylistic choice. The confidence word in each source line — stated vs reported — is inherited mechanically from the claim record, not chosen by the model.

What people will actually ask

  • "Has anyone announced sodium-ion at volume, or is it all pilot lines?" — the question the dissent slot keeps answering
  • "Which Indian OEMs have revised export guidance in the last year?" — needs the claim graph; impossible with a search index
  • "What did we know about the Hungary plant before the January briefing?" — the archive as memory
  • "Who supplies cells to Ather?" — entity relationships, resolved

10When it declines

The screen that protects everything else. Below a retrieval-coverage threshold the agent says what it lacks rather than generating something plausible.

What is Tesla's 2027 battery cost per kWh target?
Ask
I don't have this in the record.

The archive holds 14 Tesla claims about battery chemistry and pack architecture, but nothing stating a 2027 cost-per-kWh target. I can see analyst estimates from two Tier C sources, but those are projections, not company statements — and answering with them would misrepresent what we actually know.

Closest in the record: pack architecture claims from Apr 2026 (CLM-3980) and a Tier C cost projection from Rho Motion, Jun 2026 (CLM-4102).
COVERAGE 0.31 · THRESHOLD 0.60 · DECLINED

This is a feature, and it should look like one. The refusal is specific — it says what exists, what does not, and why the near-miss is not good enough. A vague "I don't know" wastes the reader's time; this one tells them where the edge of the record is.

The commercial logic of declining

One confident wrong answer about a competitor's numbers, to a reader who works in the industry, costs more than fifty right answers gain. In a paid tool the instinct is to always produce output — here that instinct is exactly backwards, and the interface is designed to make refusal feel like rigour rather than failure.

11Company pages — the archive made visible

Where the source-of-record principle becomes something a reader can look at. Every entity accumulates a claim timeline, and the timeline shows revisions rather than hiding them.

Read it bottom-up and the story tells itself: confirmed, quietly slipped, then vaguer still. No individual article says this. The record does — and only because nothing was ever overwritten. This is the schema decision from §06 of the build document, rendered.

These pages are also the growth engine

Company pages are public and indexed. Somebody searching "BYD Hungary plant timeline" finds a page no publisher has, because publishers write articles, not records. That is organic acquisition arriving with the product's core value already demonstrated — and it costs nothing extra to build, because the data is already there.

Four tabs, and one of them is the account. There is no discover tab, no trending, no follower count. The app is finishable — a reader opens it Monday, reads for four minutes, and is done. That restraint is a positioning choice: we are the opposite of the thing that broke trust.

The internal screen nobody thinks about

The calibration console ships in Phase 1, before anything public. It shows the assembled brief with every claim's score, gate results and rejected candidates — so the reviewer can see not just what was published but what was discarded and why. That view is how the rubric gets tuned in the first 8–12 weeks, and skipping it means calibrating blind.

14What this interface deliberately is not

Each of these is a thing a product like this normally has, and each is left out on purpose.

  • No feed. The brief ends. There is nothing to scroll into. A reader who finishes is finished.
  • No follower counts, likes or comments. No social layer at all — that was the conclusion from the very first conversation and the interface holds the line.
  • No engagement notifications. One push a week when the brief lands. Nothing else, ever.
  • No truncated free content. Nothing is blurred, teased or cut short to force an upgrade.
  • No personalised filter bubble. Follows reorder the brief; they never hide items. Knowing what the industry is doing is the point.
  • No AI chat bubble in the corner. Ask is a destination with citations and a refusal threshold, not an assistant that will say anything.
Why the restraint is the positioning

The premise this business started from is that trust collapsed because volume became free. A product built on that premise cannot then optimise for time-on-site, engagement loops or infinite scroll without arguing against itself.

Every omission above is also a cost saving and a build-speed gain. The disciplined version is cheaper and more credible — which is the rare case where the right thing and the easy thing agree.
