Your life in chapters

A move, a relationship, a course of study, a job, a project: these chapters can overlap. A timeline gives them a shared scale without forcing them into a résumé.

Make a timeline, add your chapters, and choose how far the view extends. That horizon is a setting you control, not a prediction of how long you will live. You can keep the result on your device, share a link, or embed it on a website. No account is required.

Give your agent a few milestones, a résumé, or an optional LinkedIn profile. The Lifecharts skill helps it turn that material into an editable timeline and a link you can open here. A birthday is optional; a career, a project, or a single chapter can have its own starting point.

Your agent should use only sources you authorize, keep uncertain dates approximate, and leave missing facts for you to fill in. Lifecharts does not fetch your LinkedIn profile or fill in personal history by itself.

Lifecharts is made by Hraness. It began in August 2026 as Life Days Left, a daily chart of U.S. generations; that model’s data and methodology remain available.

Saved drafts are stored in this browser. This is not an account or a cloud backup: clearing browser data can remove it, and another device does not automatically have a copy.

A full timeline link includes the dates and text you entered, including any birthday and chapter labels. Anyone who receives the link can read that content and pass it on. The link is encoded, not encrypted. Review your timeline before sharing it or publishing an embed, especially if it mentions other people.

Standard links keep the chart in the URL fragment, after the #. Browsers do not send that fragment to our server. These links have a generic Lifecharts preview when you paste them into another app.

The optional “Include a personalized link preview” setting creates a link that sends your complete chart to our server so we can render its title and chapter count for social previews. Link-preview services can read and cache the chart and image. Use it only for a chart you intend to make public. Both kinds of link are excluded from search; neither requires an account or loads analytics.

Changing your local draft does not change a link you already shared. Copies of that link remain readable; there is no account-based access control or recall. Being excluded from search results does not make a shared timeline private.

Older rounded snapshot links, such as /share/60-percent-ahead, work differently. They contain only a rounded percentage, without a birthday or chapter text. They remain available.

Anonymous site-health analytics run only on the production site at lifecharts.io. PostHog receives page and performance events without cookies, person profiles, persistent identifiers, automatic interaction capture, or session replay. On the homepage, it also counts example selections (career, education, or project) and completed saves. These events contain no timeline titles, dates, chapters, or links. Query strings and URL fragments are stripped. Full timeline viewers at /view and widgets at /embed do not load analytics. Older rounded share snapshots also send no analytics. Unrecognized paths are recorded only as /private.

The project began as Life Days Left, with a daily chart comparing U.S. birth-year groups under one declared population model. The data and downloads remain available, along with the formula, sources, and limitations.

The personal timeline’s chosen horizon is separate from those population estimates. Neither is an individual prognosis. No independent statistical reviewer has checked the research explainers yet, and each article says so under its byline.

• We cite primary research, official government tables, and the source authors’ own documentation, and link each source beside the claim it supports.
• Research, data, and methodology pages name the model or dataset version they use and keep a source update separate from the daily passage of time.
• Historical events and measurements carry the dates needed to interpret them.
• We state uncertainty and omitted variables in plain language, and we don’t present observational associations as causes or as claims about a person.
• We correct calculations and source descriptions on the page where they appear, then update the model or article date when the change is material.

To flag a possible error, open an issue on the public Lifecharts repository ↗ with the public page and a description of the issue. Do not send a personal timeline link unless you intend to share everything it contains. For a data correction, include the disputed value and its primary source.

Start from a birthday, a first job, or the first day of a project, and pick a horizon that helps you arrange the chapters.

The original generation model is a population illustration. The method page lists its assumptions.
