Log it. Count it.
Mourn it when it ends.

A hyperfixation is an intense, consuming focus on one specific thing — a song, a show, a fic, a ship, a person, a niche historical event — that takes over your brain for days, weeks, or months at a time. It's different from a regular interest because it's involuntary and absorbing: you're not choosing to think about it, it's just happening. The term was popularized by the ADHD and autistic communities, but plenty of people experience hyperfixation without a formal diagnosis. If you've ever had to stop yourself from sending a fifth paragraph about the same topic in a group chat, you know what this is.

Hyperfix lets you log a current fixation — its name, the category (song, fic, ship, show, game, real person, niche historical event, anything), and a start date. From there it counts the days automatically. You add an intensity rating, a private note, and optionally a public one. When the fix ends, you mark it done and Hyperfix writes a eulogy: a shareable card summarizing the run — day count, peak intensity, the note you wrote at day 3. Everything is archivable. You end up with a graveyard of past selves and the things that consumed them.

Notion templates are databases. They require you to design your own schema, update it manually, remember to open the app, and stare at a table. Hyperfix is built around the specific shape of a hyperfixation: a counter that ticks in real time, an intensity meter, a eulogy at the end. It's also social in a way Notion never is — every fix generates a shareable card designed to drop into a group chat. The difference is between a spreadsheet and a diary. Both store information. Only one is worth reading.

Clinical tools are built to help you manage or reduce unwanted thoughts — they're oriented toward intervention and treatment. Hyperfix doesn't pathologize hyperfixation. We're not trying to get you to have fewer of them. The goal is to give your current fixation a home and to give past fixations a record. We're the Letterboxd for your obsessions, not the CBT worksheet. That said: if you're using Hyperfix and you notice your fixations are causing real distress or disrupting your life, please talk to someone who can actually help. We're a tracker, not a therapist.

People who re-read the same fanfic. People who have a dedicated playlist for a single character. People who can explain the entire lore of a game they've never played. People whose Spotify Wrapped is twenty-three listens to one song from one week in March. BookTok readers. Ao3 regulars. K-pop fans deep in a bias era. Anyone who has used the phrase 'I am unwell about this' unironically and meant it. You don't need an ADHD diagnosis to use Hyperfix, though a disproportionate number of early users have one.

Yes. Most people have a primary fixation and one or two secondary ones running in parallel — Hyperfix calls these your active fixes. You can have as many active as you want on Pro, and up to three on the free tier. Each one gets its own counter, card, and eventual eulogy. The dashboard shows them all ranked by intensity so you can see at a glance which one is currently running your life the hardest.
