A browser extension for studying: research tabs sorted by subject, lecture pages that reopen when it is time to revise them, and a study timer that keeps the feed shut until your break. Everything here is free, with no account.
The problem
An essay's sources in one window, last week's lecture slides in another, a past paper you meant to try, the reading list you have not started, and somewhere in the strip the timetable. You keep them all open because closing one feels like losing it - so the browser becomes the to-do list, it slows down, and the one page you need at 9am on Monday is impossible to find. None of that is a discipline problem. Tabs simply have no idea which subject they belong to or when you need them.
Workflows
Six things students actually do with Latr. Each uses features that are free and already in the extension; pick the ones that fit how you study.
Write a grouping rule per module - your course site's address, or
title: and a word from the module's page titles - and new tabs that
match join a named, coloured tab group on their own. Five rules are free, which
is a term's worth of modules. To tidy a pile that is already open, one press
groups every tab by site. More in grouping tabs
automatically.
Save this week's lecture page with a time and close it. Set it to repeat - every Monday at 9, or every weekday through exam season - and it reopens on its own each time, with a notification. That is a revision timetable that opens the material for you. See recurring website reminders.
Keep saves a page with no time into your library. Make a folder for each module (subfolders for each topic), tag across them - "exam", "essay 2" - and turn on Track progress on a folder to see how many readings are done and open the next one. Select a passage on any page and right-click Save this highlight; highlights are searchable later.
Start a focus session from the Latr popup - 25 minutes on, 5 off by default, all adjustable - and the sites on your list stay shut until the break. Start it from a reading and that page opens first. How the blocking works, and what it does not do.
Finished with Statistics for today? Save the window, name it "Statistics - week 6", and close it. Next time, one press reopens every tab in a new window with its groups rebuilt. Keep separate sessions for study and for everything else, and nothing leaks between them.
For a group project, select the sources and copy one link - up to 50 pages, with their titles. Nothing is uploaded: the list rides inside the link. Classmates without Latr can open every page in it; with Latr in Chrome or Edge, they add the whole set in one click. Sharing tabs has the details.
And for the long article you were halfway through: a saved page reopens at the line you stopped reading, not at the top - reopening where you left off.
The timer
Most study timers count down and nothing else. This one sits in the browser you are studying in, so it can do the three things a counter cannot: keep the distractions shut, hold your reminders until the break, and tell you when to stop.
Focus time
Study without distractions
Sites on your list stay shut, or switch the list round so only your course sites open. Reminders that come due wait rather than interrupting. The timer keeps running when the popup closes and the toolbar shows the minutes left. For the full cycle, see the Pomodoro timer.
The break
A reminder to stop
When focus time ends, a notification says so - that is your reminder to take a break from studying. A longer one comes every fourth round. The blocked sites open and any held reminders arrive. The record of your study and break time is minutes and sessions per day, with no streak to keep.
Before you install
Latr works in Chrome, Edge and Firefox on a computer, and in Brave, Vivaldi, Opera and Arc from the Chrome Web Store. There is no phone app and no Safari version. It needs no account, so there is nothing to sign up for with a university email, and your tabs stay in your own browser.
Free
Every workflow on this page: reminders and repeats, saving and restoring windows, the library with unlimited folders and tags, the timer, site blocking, share links, and five grouping rules. There is no cap on how much you save and no trial that runs out.
Worth knowing
Reminders need the browser running to fire, so for a hand-in deadline send the reminder to your calendar as well, so your phone can alert you. Pro is an optional one-time purchase for themes, sounds and higher limits - see pricing.
Questions
Latr is both, and the two work together: the timer can keep distracting sites shut while you revise, any reminders that come due wait for your break, and a session can start from the reading you are working on. The tab side keeps every open tab in one list, groups them by subject and saves a whole window to reopen later. It all runs in Chrome, Edge and Firefox, with no account.
For a whole window, save it from Latr - give it a name like the module - and close it; tomorrow, one press opens every tab again with its groups. For a single page, save it with a time such as “tomorrow 9am” and close the tab: at nine it reopens on its own, at the line you stopped reading on a long page.
Yes. Save the page with a time and set Repeat to daily, every weekday, or particular days such as Monday and Thursday. Each time it comes round, the page reopens on its own with a notification, and the next one is already set. Repeats are free, with no limit on how many you have.
Add the sites that pull you away to Latr’s focus list, or switch it to allow only the sites your course needs. While the focus part of a session runs, a blocked site opens a page saying how long is left instead; on the break everything opens again. It works inside the browser only - it is not a system-wide blocker, and you can always end a session.
Select the pages - a saved window, or a set from your library - and copy one share link. It carries up to 50 pages with their titles, inside the link itself, so nothing is uploaded anywhere. A classmate without Latr still sees the list and can open every page; one who has Latr in Chrome or Edge can add them all in one click.
Everything on this page is free, with no trial and no cap on how much you save. The paid tier, Pro, is a one-time purchase for personalisation - colour themes, sounds - and a few higher limits, such as more than five automatic grouping rules. Nothing that makes a reminder fire, repeat or reopen is ever paid.
No - Latr is a desktop browser extension, and there is no phone app and no Safari version. Reminders also need the browser running to fire. For a deadline you cannot miss, send the reminder to your calendar as well - Latr hands it over in one click or as an .ics file - and your phone’s calendar can alert you for it.
Free, no account, and nothing leaves your device. About ten seconds to install, and one keystroke to use.
Also on Brave, Vivaldi, Arc and Opera - straight from the Chrome Web Store listing.
