Logo & mark
Four squares on a grid. The bottom-right square is always the brand blue — never anything else.
Variants
Don't
Color — restrained, defined.
One accent. Strict neutrals. Every value mirrors between light and dark so layouts don't drift across modes.
Used on a single primary action per surface, on the bottom-right logo square, for citations and confidence signals, and for italic-serif emphasis spans. Never used for body text or large surfaces.
Page canvas in light mode. Off-white with a warm bias to feel editorial rather than clinical.
Page canvas in dark mode. Near-black, never pure black, so the screen feels physical.
Headlines and body text on light canvases. Slightly green-shifted to avoid feeling like pure print.
Headlines and body text on dark canvases. Warm cream — never bright white — to reduce eye fatigue.
Tokens — full pair
Typography
Geist for everything structural. Instrument Serif italic for single-word accents — never sentences. Geist Mono for tokens, labels, and timestamps.
Spacing & radii.
An 8-point scale that bends to 4 for inline details. Five radii — not more.

Components.
The actual atoms used on every surface. Copy them — don't reinvent.

Structured fields, on your schema.
Define columns. Blockdata fills them with citations and a confidence score.
Iconography.
1.3px stroke, 14×14 base grid, rounded line caps. Single weight — never filled and outlined together.
Voice & tone.
Editorial. Confident. Specific. We never say "leverage." We never say "synergy." We never use 12 words when 7 will do.
Numbers and nouns, not adjectives.
If we have a stat, we use it. If we have a customer name, we name it. Vague superlatives — "powerful," "robust," "best-in-class" — are removed every time.
We tell you what it isn't.
Document AI vendors over-promise. We don't. If a feature isn't ready, we say so. If a model is wrong 4% of the time, we tell you that's where the review queue comes in.
Read aloud, it should land.
Headlines have rhythm. Paragraphs end on a noun, not a clause. Italic-serif accents do one job: emphasis. Use them like a comma — sparingly, and on purpose.
We're a workbench, not a wand.
The product is a set of tools your team operates. We talk like the people running pipelines at 2am, not like a keynote.

Turn every document into trusted data.
Blockdata is the workbench where teams turn documents and databases into blocks — atomic, cited, queryable.
