Nimex: A Simple Tool to Track Your Anime Episodes Without the Hassle

If you're anything like me, keeping track of weekly anime episodes slowly becomes a mini‑game of its own. One moment you're sure the next episode drops on Friday… the next moment you find out it actually aired yesterday, and your friends start giving spoilers. I used to hop between AniList, streaming apps, fandom wikis, and calendars just to keep up.

So, I built Nimex — a browser extension that quietly takes care of the entire schedule for you.

Now that version v1.1 is live with bug fixes and polish, I figured it was the perfect time to write a proper article about it.

Why I Made Nimex

The motivation came from one simple frustration:
I follow too many airing shows.

Some air daily. Some are in odd time zones. Some disappear for a week and then suddenly drop a new episode at 2 AM. I kept missing episodes or constantly refreshing AniList for updates.

Nimex grew out of that annoyance. I wanted something that:

  • Shows what’s airing today, tomorrow, and the next 7 days.
  • Highlights the shows I care about.
  • Sends a notification immediately when a new episode is out.
  • Lives directly in the browser, just one click away.

Nothing more, nothing less.

What Nimex Does

At its core, Nimex is a weekly anime schedule viewer + episode notifier.
Here’s the full breakdown:

1. 7‑Day Anime Release Chart

When you open the extension, you're greeted with a clean grid of everything airing in the coming week. Each day displays:

  • Episode number
  • Exact airing date and time
  • Anime cover art

It’s like a mini dashboard for your entire seasonal watchlist.

2. Favorites and Episode Alerts

See something you’re watching? Click the little heart icon.
Nimex adds it to your favorites and automatically sends a notification when the next episode is released.

You don’t have to check anything manually. No more missing drops. No more digging for countdowns.

3. Quick Search + Anime Preview

You can search for any anime directly from the extension. Opening an anime title shows:

  • Cover & banner art
  • Synopsis/Description
  • Next episode countdown and info

You can also follow or unfollow a show right from this preview.

4. Fast, Lightweight, and Privacy-Respecting

Everything stays on your device:

  • No backend server
  • No analytics
  • No tracking
  • No data collection

Nimex uses only one external source: AniList’s GraphQL API, purely to fetch the airing schedules.

Version 1.1 – Bug Fixes, Stability, and UI Polish

After releasing the first version, I spent a few days refining things and fixing edge cases. Version 1.1 includes:

1. Notification Reliability Fixes

Previously, browser restrictions and CORS issues occasionally blocked cover images in notifications. Now, Nimex gracefully falls back to the built‑in icon when needed, guaranteeing the notification always fires.

2. Favorites Sync Cleanup

In the previous version, episode numbers weren’t always matched with their last notified episode. Now, the extension tracks lastNotifiedEpisode and nextEpisode accurately to prevent double notifications.

3. Weekly Schedule Cache Improvements

Nimex now caches the schedule, refreshes intelligently every 24 hours, and polls only when needed. This makes the extension feel much snappier when opened repeatedly.

4. UI Polish

Based on feedback:

  • The search bar now animates smoothly.
  • The Favorites view is cleaner.
  • Overflow scrolling behaves correctly.
  • Various small animation and layout fixes.

How Nimex Works

Nimex runs as a Chrome Extension (Manifest V3) with a background service worker.
Here’s the logic loop running behind the scenes:

  1. Fetch anime airing data from AniList once a day.
  2. Monitor your specific followed anime list.
  3. Check every 15 minutes for new episode releases.
  4. Trigger a notification if:
    • The anime is in your favorites.
    • A new episode is scheduled.
    • You haven't been notified about that specific episode yet.

All scheduling and notifications are handled locally by chrome.alarms.

My Personal Use Case

In my own daily routine, Nimex has become a tiny companion that stops me from forgetting episode releases. When I open my browser in the morning, I get a neat little overview of what’s coming out today.

If I’m watching something weekly, Nimex quietly reminds me the moment the next episode is announced. I don’t need to check apps, track countdowns, or rely on memory.

I built it for myself—but I realized a lot of anime fans have the same problem.

What’s Next?

I’m already planning:

  • Optional onboarding screen
  • Theme improvements
  • Manual refresh button
  • Possibly a Firefox version

If enough people use Nimex, I’ll continue expanding it based entirely on user feedback.

Final Thoughts

Nimex is small, simple, and focused.
It does one job extremely well:

"Tell me when the next episode of the anime I love is coming."

If you’re tired of bouncing between apps or missing episode drops, give it a try.

It’s free, open (in spirit), privacy‑friendly, and built with care.
