Import Your Watch History From TV Time, Trakt, Letterboxd, and Simkl

When people consider moving to a new tracker, the questions are usually practical: how it looks, how it feels, what it remembers. But the thing that actually stops the move is almost never the interface. It is the archive. Years of watching, thousands of episodes checked off one at a time, and no reasonable way to carry any of it forward. “I’m not re-checking 4,000 episodes by hand” is not a complaint. It is a completely rational boundary, and it is the reason people stay on trackers they have quietly outgrown.

ScreenAtlas can now import your watch history from other trackers, and export your own library back out. Moving in should be boring. Moving out should be just as boring. Both directions matter, because your history is yours.

Bringing your history from where it already lives

You can import from TV Time (its GDPR export ZIP), Trakt (ZIP or JSON), Letterboxd (ZIP or CSV), and Simkl (ZIP, JSON, or CSV). If your old app is none of those, a generic episodes CSV works too, as does a ScreenAtlas native JSON export, which is handy if you are moving between accounts or restoring a copy you took earlier.

You do not need to know exactly which format you downloaded. Detection looks at the file’s actual bytes, never its name or type, so a file called export.zip that is really a CSV will not confuse it. There is also an “I’m not sure” option: hand it any supported file and let it work out the rest. And if the file does not match the source you picked, it detects the real format and simply tells you, rather than failing with a cryptic error.

What comes across is the substance of your watching: shows, movies, episodes watched, ratings, your watchlist, and rewatches, including individual rewatch events. Lists arrive too when you import a native JSON export. Ratings are normalised to the ScreenAtlas 1 to 5 scale along the way: Trakt and Simkl’s 1 to 10 scores are halved and rounded up, Letterboxd half-stars are rounded up, and TV Time’s vote scales are mapped. What does not come across is anything that belongs to your old account rather than your watching: comments, reviews, likes, badges, stats, and personal or account details stay behind.

Files can be up to 50 MB, there is a daily import limit, and one import runs at a time.

It will not guess

A migration tool that quietly invents matches is worse than no tool at all, so ScreenAtlas does not guess. A title that cannot be confidently matched to the catalog is never forced into a near-miss. It goes into an unmatched report instead, with a reason, grouped by title, so one show with 200 unmatched episodes is a single line to look at rather than 200 rows of noise. You see exactly what moved and exactly what did not.

Re-running is safe in the same deliberate way. Every write is replay-safe and idempotent: importing the same file twice changes nothing. You get a message that the file was already imported and nothing new was added. There is no duplicate-everything surprise waiting behind a second click, which means you can take your time with it.

Taking it with you too

Import only feels safe if the exit is just as open, so export is a first-class direction, not an afterthought. You get a full JSON copy of your shows, movies, episodes, ratings, rewatches, and lists. The download link is emailed to you and works for 7 days. Keep it, restore from it later, or just know it is there.

How to start

Everything lives in the Import / export wizard: in the app under Profile, and on the web dashboard at screenatlas.app/web. You pick a direction, import or export, and walk through it step by step.

The practical next step is small. Export your history from your old tracker, whatever shape that file comes in, and drop it into ScreenAtlas. The boring part is now actually boring, and the episodes stay checked.
