More than a tracker
Every episode has its own conversation.
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.
- Reactions
Rate each episode, pick how it made you feel and vote for who stole the scene, then see what everyone else thought.
- GIFs and memes
Reply with a GIF, or turn a still from the episode into a meme in a couple of taps.
- Badges
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.
A TV show tracker that remembers where you’re up to
haveseen is a free watch tracker for everything on screen — TV series, anime and films — in one place. No app to install: it works in your browser on your phone, tablet or computer.
Every episode, ticked off
A full episode guide for each show, with titles, air dates and synopses. Tick episodes as you go, or mark a whole season at once.
Always know what’s next
“Up next” shows the next episode to watch, and airing shows tell you when the new one lands.
Anime and films too
Track anime with AniList data — even 1,000-episode series — and keep a diary of every film you watch, with ratings and notes.
Bring your history
Import your viewing history from Netflix, Prime Video, TV Time, Letterboxd, MyAnimeList, Crunchyroll and more in about a minute.
Your watching, in numbers
Hours watched, episodes, favourite genres, the best-rated show you’ve seen and its best episode.

Questions
Is haveseen free?
Yes. haveseen is free to use — log as many shows, anime and films as you like, and create a free account to sync them between devices.
Can I talk about episodes without spoilers?
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.
Do I need to download an app?
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.
Can I import my Netflix or Prime Video watch history?
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+.
I used TV Time. Can I bring my history over?
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.
Does haveseen track anime?
Yes. Anime uses AniList’s database, including episode titles and when the next episode airs, and you can import your MyAnimeList list.
Who can see my watch history?
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.
