📅 Visual planning on a timeline

Plan anything on a visual timeline

Timelines turns your projects, milestones and to-dos into a zoomable, drag-and-drop canvas. Organize work into boards and swimlanes, lay out phases as bars, drop events and tasks onto the dates that matter — then read the very same content as a clean text outline.

The model

Four levels, one clear structure

Everything you create nests into a simple hierarchy — so a board can hold anything from a personal year to a multi-team roadmap without getting messy.

Level 1

Boards

Top-level timelines like Work, Personal or Archive. Switch between them as tabs and reorder by dragging.

Level 2

Swimlanes

Horizontal rows inside a board — one per team, workstream or theme. Collapsible, colorable, and shareable on their own.

Level 3

Bars & Events

Bars span a date range (open-ended too); events (points) mark a single moment. Both stack freely within a lane.

Level 4

Segments & Markers

Break a bar into phases with segments, and pin milestones on it with markers — each with its own color and notes.

The canvas

A timeline you can zoom, pan and navigate

The heart of the app is a live canvas where time flows left to right. Zoom from a single month out to five years, scrub across dates, and always find your place.

  • Zoom levels from 1 month to 5 years, plus wheel-zoom anchored at the cursor
  • Pan with the middle mouse button or a horizontal trackpad swipe
  • “Center on today” jumps the view back to the current date
  • Date grid, weekend bands, a live current-date line and a hover-date readout
  • Click empty space to create a bar or event pre-filled with that date

Building blocks

Bars, segments, markers and events

Compose a timeline from a small, consistent set of pieces. Every item carries a title, a rich description and a color from the standard 10-color palette.

  • Bars — a titled span between two dates, or open-ended into the future
  • Segments — sub-spans inside a bar for phases or stages
  • Markers — milestones pinned to an exact moment on a bar
  • Events — standalone points on a swimlane at a single date
  • Resize bars and segments right on the canvas by dragging their edges

Tasks & deadlines

Turn any event into a checkable task

Mark an event or marker as a task and it becomes a checkbox you can resolve. The timeline keeps an eye on what’s slipping so nothing quietly falls behind.

  • Two kinds of items: standard pins and resolvable tasks
  • Tick a task off directly on the canvas or in the outline
  • Overdue, unresolved tasks get an unmissable highlight
  • A dedicated Resolver role can tick tasks without editing anything else

Organize by dragging

Rearrange everything with drag & drop

Structure is never locked in. Grab anything and move it — the layout follows your hand, and the new order is saved for you.

  • Reorder boards, swimlanes, bars and events by dragging
  • Drag a swimlane onto another board’s tab to move it there
  • Move a bar or event into a different swimlane entirely
  • Stack items vertically within a lane in the order you want

Outline view

The same content, as a text outline

Prefer words to a canvas? Flip to the outline view for a hierarchical, document-like take on your swimlane — with a table of contents and everything editable in place.

  • Browse a board → swimlane tree on the left, content on the right
  • Edit titles and dates inline, without opening a form
  • Jump around with an auto-generated table of contents
  • Descriptions render as Markdown; links open in a new tab

Sharing & collaboration

Share a swimlane, control who does what

Invite people to a single swimlane by email and pick exactly how much they can do. Shared lanes show up on a dedicated board for everyone they’re shared with.

Share panel — invite by email, pick a role, and manage grantees with Active/Pending status

Roles that map to real needs

Each person gets one of four roles. Owners run the lane; the rest see a view tailored to what they’re allowed to change.

  • Invite by email — invitations show as Pending until accepted, then Active
  • Change a role or revoke access at any time
  • Edits sync with automatic merging, so simultaneous changes don’t clobber each other

And more

Everything else that keeps it yours

Small conveniences that add up — from how you sign in to how you get your data out.

🔎

Upcoming filter

Hide everything except what’s due in the window ahead, so you can focus on what’s next. Overdue tasks always stay in view.

🌗

Light & dark themes

A polished light theme and an easy-on-the-eyes dark theme, remembered per device.

🔐

Email or Google sign-in

Register with email and password (with email verification) or sign in with Google. Use the same address and the two link to one account.

📦

Import & export

Take everything with you — export all your boards and swimlanes as a single bundle, and import it back whenever you like.

🔑

API key

Issue a personal API key to authenticate external integrations, then regenerate or revoke it on demand.

📄

Markdown everywhere

Write descriptions in Markdown — headings, lists, links and emphasis all render cleanly across both views.
