Decided, not guessed.
Taumorrow builds systems whose every step is a proof anyone can check. The brand says the same thing the systems do: say what is, show the record, let anyone recompute it. This page holds the mark, the colours, the type and the voice, with files to download.

01
The mark: the gate
A T whose stem turns through a hook. Read it as the T of Taumorrow, or as the τ of the language it is built on. The hook is the turn a move takes through a decided gate: the search proposes, the logic admits. The rounded square is a cell of a board, and a record in a chain.

Lockup
Mark and wordmark sit on one line. The mark is as tall as the wordmark’s cap height plus its descender; the gap between them is half the mark’s width. The wordmark is Bricolage Grotesque Bold, tracked −2 %. Nothing else is added to the lockup: no tagline inside it, no outline, no shadow.

Clear space and minimum size
Keep a margin of half the mark’s width free on every side of the mark or lockup. The mark stays legible down to 16 pixels; the lockup needs 120 pixels of width. Below that, use the mark alone.
What not to do
- Do not rotate, skew, outline or add effects to the mark. It is flat and upright.
- Do not recolour it outside the palette below. On photographs, use the white glyph on a dark area or the mark on its own square.
- Do not replace the mark with a Greek τ from a font, and do not use the Tau language’s own logo for Taumorrow. The language is IDNI AG’s; the mark is ours.
- Do not set the wordmark in another typeface, in all caps, or as “TauMorrow” or “Tau Morrow”. It is one word with one capital.
02
Colour
One blue carries the brand. Everything else is paper, ink and a single warm signal for things that are live right now. The dark theme is not an inversion: the blue lightens to stay legible, and the paper becomes night.
Blue means decided, chosen, ours. Signal means live and happening now, and nothing else. Chain grey is for rules, hashes, dates and records. Red is never a brand colour; a loss is written as a number, not painted.
03
Type
Three faces, each with one job. Headlines are set in Bricolage Grotesque, text in Source Sans 3, and anything that is a record, a number or a hash in JetBrains Mono. Chinese uses Noto Sans SC, Thai uses Noto Sans Thai.
Bricolage Grotesque Bold, tracked −2 %, for headlines and the wordmark.
Source Sans 3 Regular and Semibold for running text. Lines stay near 65 characters. Numbers inside text use tabular figures.

Image language
Behind the brand runs a wiring lattice: small formulas as nodes, dependencies as edges, values as pulses travelling along the wires. It moves slowly, never behind text, and stops for people who prefer reduced motion. No stock photography, no robots, no glowing brains.
04
Voice
The brand speaks the way a record reads. Short sentences, concrete nouns, the number before the adjective.
Say what is
“9 : 1 against Claude Sonnet 5.5, ten games, public.” Not “crushing”, not “undefeated”. A loss is a line in the record, and it stays there.
Show the source
Every claim points at a paper with a DOI, a repository, or a live page. If there is no source yet, the claim waits.
Credit the language
Taumorrow is built on the Tau language, the work of IDNI AG and Ohad Asor. The architecture, the games and the engine are Taumorrow’s. Both halves are said in full.
Decided, not guessed
The claim is the method: a step is taken only after the logic has decided it. The brand never says “AI” where it means a proof, and never promises what has not been run.
Patent pending, not patented
Applications are filed. Until a patent is granted the words are “patent pending” or “applications filed”, with no country named.
Plain words for hard things
No “revolutionary”, “disruptive”, “next-gen”. A new idea is explained in one sentence a chess player and a logician can both follow.
Names
- Taumorrow, one word, capital T, in every language and script. Never TauMorrow, Tau Morrow or TAUMORROW in running text.
- The descriptor is “built on the Tau language”. The name of the language belongs to IDNI AG and is used only to say what Taumorrow is built on.
- Works are called by their paper titles: The Admitted Shortcut, The Round as a Formula, A Playable Nomic.
