IBM's Deep Blue, the chess computer that defeated Garry Kasparov in 1997, on display at the Computer History Museum

From Llull's combinatorial wheels and Leibniz's calculus of reasoning to today's large language models: ideas, programs, machines, games, people, companies and the policy around them. Moments are tagged (symbolic AI, machine learning, neural networks, robotics, games, language, vision, policy & safety, people, industry) and colored by their first tag; the field's eras, including both AI winters, are shown as spans. Each moment links to its sources on Wikipedia; summaries are our own, and dates given only as a year or month are marked approximate where uncertain.

Compiled by an AI assistant (Claude) through the OpenChronology API and reviewed by the account owner. Coverage of the most recent years stops at the assistant's knowledge.

Duration correction: Ongoing subjects previously drawn through a present/research cutoff are represented at their original starts, with no end asserted. Existing moments at those coordinates are reused; their attached cards retain the former duration’s notes, sources, tags and media. Bounded historical and coverage intervals remain durations.

Moment details

Separate by tags

Events with any chosen tag move into a track above the rest of the timeline. Nothing is changed or saved.

Shift or scale times

Each time becomes (time − around) × scale + around + offset, exactly, as comparisons align timelines. A duration’s start or end that follows a moment moves with that moment.

        Your draft becomes a pull request. The upstream timeline stays unchanged until someone with write access merges it.

        Timeline plugins

        Plugin suites

        A suite adds several plugins at once. Plugins this timeline already has stay as they are.

        Create a suite

        Package this timeline's plugins to add them to other timelines at once. The suite carries each plugin's definition, custom plugins included.

        Plugins

        Plugin editor

        Define metadata fields and a restricted render script. No DOM, network, imports, loops or arbitrary calls. Later plugins override earlier effects. Installing takes effect immediately; publishing makes this version public in the server library.

        Plugin library

        Popularity counts public timelines with the plugin enabled.

        Compare timelines

        Select two to eight timelines visible to your account, or add a JSON file.

        Choose a shared time display

        These timelines use different printers or parsers. Choose the display for this comparison. Original times stay unchanged; use scale and offset to align different coordinate conventions.

        Timeline time display

        These settings belong to this timeline and are included in saved files and server copies. Times stay exact.

        Numeric labels are rounded. SI prefixes work best with unit symbols such as s. A Julian year is exactly 365.25 days.

        Displayed value = (stored time − origin) / scale. For Gregorian display, the displayed unit is one second from 1970-01-01T00:00:00Z.

        Preview uses the current window span and viewport width. Custom helpers: hasView(), viewLeft(), viewRight(), viewSpan(), viewWidth(), unitsPerPixel(), labelResolution(), purpose(). Existing printers and parsers can ignore this context.

        New timeline from files

        A moment for each file, dated as you choose. Its source is the file itself: open it from the moment in the file's own app. Nothing is copied, and file paths are never saved to a server.

          Servers

          The official server is https://timescale.info. You can connect to your own HTTPS servers too, and sign in to several at once: your timelines from each are listed together. Local .och files work without a connection.
