1/ Context

Chronos is my side project — a comparative-historiography tool built on one idea: history reads differently in parallel. One date, four lenses — philosophy, architecture, art and politics lined up on a single rail, so the connections teach themselves: the Parthenon rises while Socrates still walks Athens; Corinth falls and Hellenistic art stops mid-sentence.

It started as an educational and research experiment, then grew into a running SaaS. I use it daily myself and opened it to a narrow circle of people who care about the subject — a deliberately small audience that actually uses the thing.

2/ The work

No client, no team, no hand-offs — this is what my process looks like when one person carries all of it:

  • The idea and the method. From a reading habit to a product concept: comparative timelines as the core mechanic, not a feature.
  • Brand and system. A Bauhaus identity — circle, square, triangle as the discipline marks — carried from the logo into a full component system.
  • The product. Three readings of the same data: a dense research grid, a calm reading view, and a causality view that pins an event's chain of consequences. Plus the public landing and an iOS companion.
  • The build. Front end and back end shipped in AI-assisted code sessions — my AI-first workflow doing production work, not demos. Deployed, monitored, operated by me.

3/ Screens

chronos / 01 — research board
Chronos research board: a Bauhaus-style grid with philosophy, architecture, art and politics columns aligned to one BC date rail
The research board — four disciplines against one date rail. The grid is the argument: what happened next to what.
chronos / 02 — reading view
Chronos calm reading view: the same four-column timeline as light cards with tags and event counts
The calm view — same data, softer rhythm, built for long reading sessions rather than research sprints.
chronos / 03 — causality view
Chronos causality view: events on a vertical rail with coloured arcs linking causes to consequences, from Solon's reforms to the Parthenon
Causality view — hover an event, pin its chain: Solon's reforms arc to Cleisthenes, Cleisthenes to the Parthenon, the Parthenon to Phidias.
chronos / 04 — public landing
Chronos landing page: 'History reads differently in parallel' headline, a live timeline preview and the four discipline lenses
The landing — the product explains its method in one screen, with a live preview instead of marketing renders.
Chronos iOS app: large-title timeline list filtered to the Philosophy lens
iOS — native large-title reading list, one lens at a time.
Chronos iOS app: one-bar variant with compact navigation
The one-bar variant — navigation collapsed to a single row.
Chronos iOS app: poster-style timeline screen
The poster take — the timeline as something you'd want to hang on a wall.

4/ Outcome

Chronos is what my client work looks like with no client: the same system thinking, the same design-to-code discipline — carried from first sketch to a deployed, running product by one person. It is also the proof behind my AI-first claim: an entire SaaS — brand, interface, front end, back end — shipped and operated solo.

Curious what one person can ship end to end?
