More than a tracker
Finished an episode? Rate it, say how it made you feel and jump into the discussion with everyone else who just watched it. Talk about later episodes is hidden until you get there.
Every episode and film has its own thread, with replies and upvotes, and spoilers stay hidden until you’ve watched it.
Rate each episode, pick how it made you feel and vote for who stole the scene, then see what everyone else thought.
Reply with a GIF, or turn a still from the episode into a meme in a couple of taps.
Earn badges for binges, streaks, early-bird watches and finishing a series, and show them off on your profile.
Follow friends, see what they’re watching and message them about it.

Import your viewing history from Netflix, Prime Video, TV Time, Letterboxd, MyAnimeList, Crunchyroll and more in about a minute.
Hours watched, episodes, favourite genres, the best-rated show you’ve seen and its best episode.

Yes. Every episode and film has its own discussion, and you only see it once you’ve watched that episode. Comments that mention later episodes are hidden behind a spoiler warning. You can reply, upvote, post GIFs and make memes from the episode’s stills.
No. haveseen runs in your web browser on any phone, tablet or computer. On your phone you can add it to your home screen so it opens like an app.
Yes. Streaming services don’t let other apps read your history directly, so haveseen imports the file or page they let you download or copy. The Upload page walks you through it for Netflix, Prime Video, Disney+, Crunchyroll, Max and Apple TV+.
Yes. TV Time shut down on 15 July 2026. If you downloaded your data export before then, drop the .zip on the Upload page and every episode you ticked off comes across, season by season.
Yes. Anime uses AniList’s database, including episode titles and when the next episode airs, and you can import your MyAnimeList list.
It’s up to you. Without an account, your list stays in your browser. With an account, it’s private until you set up a profile to share with friends. Profiles are public by default, and you can switch yours to friends and approved followers only at any time. Your notes are never shown to anyone. You can export or delete everything whenever you like.
