Less to hold in your head

Life is full of little things.
Give them a place to land.

A thought while you read. Something due on Friday. A friend you meant to call. They usually end up in five different places, or nowhere. Eterna keeps them together in your browser, one click away, without turning your day into a project.

In the side panel

Beside any page.

Click the star in your toolbar, or press Alt Shift N, and Eterna opens next to whatever you’re reading. Type, press Enter, and it’s saved.

01 · Write

Room for a line,
or a long page.

Start with a sentence. Titles are optional and everything saves as you type. When a thought grows, open it as a full page with a sidebar and an outline.

  • Markdown shortcuts and a “/” menu for headings, lists, to-dos, quotes and images
  • Notes inside notes, emoji icons, pins and tags
  • Search everything at once, or type #tag to filter
How writing works

02 · Remember

Keep the plan.
Remember the person.

Tasks, events and people live beside your notes. Reminders arrive as notifications while Chrome is running, and anything you missed waits in Coming up, marked Due now.

  • Tasks with due dates and reminders, ticked off with Undo
  • Events, all-day or at a time, with a reminder before
  • People and the details that matter, with a gentle nudge to follow up
Tasks and reminders

03 · Home

A calmer
new tab.

Each new tab opens on a clock, a greeting and your day: the scratchpad, what’s coming up and what you wrote last. Seren, Eterna’s little star, greets you by the time of day.

  • Corner, Full or Plain, whichever feels right
  • A focus timer for one thing at a time
  • Quiet dots by default, your own photo, or a fresh landscape each day
Make it yours

Private by design

Your notebook stays
on your computer.

No account, no cloud

Everything you write is stored in this browser. Nothing is uploaded, and there are no ads or analytics.

A copy you can keep

Back up to a single .eterna file and restore it on another computer. Archive, keep Trash for 30 days, or erase everything.

Honest small print

Eterna doesn’t encrypt your notes, and uninstalling removes them, so keep a backup. If you pick the daily photo background, a fresh photo comes from a photo service each day unless you switch that off.

Read the Privacy Policy

Questions

A little clarity.

More in the guide

What is Eterna?

A private notebook for desktop Chrome. Notes, tasks, events, people and a scratchpad live together in the side panel and on your new tab. There’s no account to create and nothing to set up.

How do I install it?

Add it from the Chrome Web Store. It’s free, with no account to create. The Get Eterna page has a few things to know first.

Does my writing leave my computer?

No. Notes, tasks, events, people and images stay in your browser. The only thing Eterna fetches is the daily photo, and only if you choose that background; you can also switch the fresh photo off in Settings. Read the details.

What happens to my new tab?

Eterna becomes your new tab, in Corner, Full or Plain style. Chrome may ask whether to keep the change: choose “Keep it”, because “Change it back” turns Eterna off. Your address bar and search stay Chrome’s.

Does it sync to my phone or another computer?

No, there’s no sync and no phone app. To move your notebook, back up to an .eterna file in Settings and restore it on the other computer. Back up before you uninstall or reset Chrome, too.

Make space for your everyday.

The little things deserve somewhere to stay.
