Getting started
Install Meguri from the download page, then
launch it. On first launch the library is empty, and a screen prompts you to
add a folder.
macOS: allow the first launch. Meguri is not notarized by
Apple (that requires a paid developer account), so macOS blocks the first
launch with an "Apple could not verify…" dialog. Dismiss it, open
System Settings → Privacy & Security, scroll down, and
click Open Anyway next to the Meguri entry. This is only
needed once. If macOS instead says the app "is damaged and can't be
opened", you have a build from v0.1.0 or earlier — download the latest
release and try again.
- Click the + button in the left sidebar (or the prompt
on the empty screen) and pick a folder that contains your videos or
photos.
- Meguri scans the folder recursively and starts generating thumbnails
in the background. Progress is shown while it works — you can start
browsing right away as items appear.
- That's it. The folder is remembered, and every later launch re-checks
it automatically for new, changed, moved, or deleted files.
Your files are safe. Meguri only ever
reads the
folders you add. It never modifies, moves, or deletes your media files.
Everything it creates (thumbnails, tags, its database) is stored separately
in its own app-data folder — see
Where your data lives.
Browsing your library
The main screen shows your library as an endless, scrollable wall of
thumbnails. Three layouts are available from the header, so you can switch
between visual browsing and detail-oriented lists:
- Grid — large thumbnails, best for visual scanning.
- List — thumbnail plus name and key details per row.
- Table — compact rows with sortable columns for
working through a lot of files quickly.
Scrolling is infinite — items load as you go, even in very large
libraries. Use Ctrl + mouse wheel (or Ctrl +
+/-) to make everything larger or smaller at any
time.
Hover to peek inside a video. Move the mouse across a
video thumbnail and it previews the scene under the cursor — left edge is
the start, right edge is the end, like scrubbing a seek bar. It works in
all three layouts, so you can check what a video contains without opening
it. If you prefer static thumbnails, turn it off in
Settings → Hover preview.
Playing videos and viewing photos
Click any thumbnail to open the detail view. It appears
over the library, so closing it (or pressing Esc) drops you right
back where you were.
- Videos play immediately with full seeking. Hovering
the seek bar shows frame previews so you can find a scene before jumping
to it. Common formats (mp4, webm, mkv, avi, and more) play in-app.
- Photos are shown full size. A Copy
image button puts the picture on your clipboard, ready to paste
into a chat or document.
- If a file uses a codec the built-in player can't handle, use
Open externally to hand it to your system's default
player.
The detail view is also where you edit a file's tags and rating, mark it
as a favorite, and add scene bookmarks.
Search and filters
The search bar at the top filters your whole library. You can combine:
- Text search — matches file names, paths, and tags
(full-text search, so partial words work).
- Kind — only videos, or only images.
- Tags — one or more tags.
- Rating — minimum ★ rating.
- Favorites — only files you've marked.
- Capture date/time — when the media was recorded.
Every active condition appears as a badge under the
search bar. Click a badge's × to remove just that condition. Sort order
(name, date, size, rating, …) is chosen next to the search bar.
Tip: clicking a tag anywhere — on a thumbnail or in the
detail view — instantly searches for that tag. A search you like can be
saved as a
smart collection.
- Tags — add free-form tags in the detail view; the
input autocompletes from tags you've already used.
- Ratings — rate files from ★ to ★★★★★.
- Favorites — a one-click heart for the files you come
back to.
All of these stick to the file's content, not its location: if
you later rename a file or move it to another folder inside the same
workspace, your tags, rating, favorite mark, and history follow it
automatically after the next scan.
Collections
Meguri has two ways to group files, for two different jobs:
| Collections | Smart collections |
| What they are |
Hand-picked sets of files, like playlists or albums. Can mix files
from different workspaces, and each can have its own emoji icon. |
Saved searches. You name a set of search conditions and re-run it
with one click. |
| How to build one |
Create a collection in the sidebar, then add files to it from the
detail view or context menu. |
Set up a search you like, then save it from the search area. |
| What's inside |
Exactly the files you added, in the order you arrange them. |
Whatever currently matches the conditions — new files that match
show up automatically. |
Discovery
The bigger a library grows, the more of it sinks out of sight.
Discovery deals you a random hand from your library and
presents each pick full-screen, one at a time — the video plays large in
the middle, with a rail of scene previews along the bottom. Hover a scene
to enlarge it, click it to jump straight to that moment, or scrub the main
video by hovering it. One click reshuffles the deck. Great for
rediscovering things you forgot you had.
Playlist playback
Any list you are looking at can play itself. Press the
play button in the bottom-right corner (or open a
collection and start it from there) and a full-screen player takes the list
exactly as it is on screen — a collection, Watch Later, a workspace
listing, or a search result, in whatever sort order you chose — and runs it
without further input.
- Videos play to the end, then the player moves on by
itself.
- Photos stay on screen for a few seconds, slowly
panning and zooming so a still image never looks frozen, then hand over to
the next item.
- Shuffle plays the rest of the pass in a random order
without repeating an item, and leaves the collection's saved order
untouched. Repeat starts the list over when it ends.
- Manual order — switch a collection's sort to
Manual order and drag items into the sequence you want. That order
is saved with the collection, so it is what plays next time too.
- Controls fade away while you watch and come back when you move the
mouse: play/pause, previous/next, volume, and full screen.
Keyboard: Space play/pause, N next,
P previous, S shuffle, F full screen,
I to step out to the current file's detail view (coming back
resumes where you left off), and Esc to leave the player and
return to the list you started from.
Tip: Settings → Playlist playback sets
how long each image is shown, whether images animate, the transition
between items, and whether shuffle is on by default.
Scene bookmarks and history
- Scene bookmarks — while watching a video, save the
current position as a named bookmark. Later, jump straight back to that
scene from the detail view.
- Playback history — Meguri remembers what you've
played and when, so recently and frequently watched items are easy to
find again. Like tags, history survives file moves and renames.
- The History view — open it from the
play-history icon in the header to see a timeline of
everything you've played, grouped by day (Today, Yesterday, …), with a
play count for each file and whether it played in-app or in an external
player. Click an entry to open the file again; Clear
history wipes the timeline if you want a fresh start.
Workspaces
Each folder you add is a workspace with its own
independent library — its own database, thumbnails, and scan schedule. The
icon rail on the far left (Slack-style) lets you add, switch between, and
remove workspaces.
- Removing a workspace removes it from Meguri only — the folder and
your media files on disk are untouched.
- The special All workspace searches across every
registered workspace at once — handy when you don't remember which
library something is in.
- Re-scan the current workspace any time with the
Scan button in the header. Scans are incremental: only
new or changed files are processed, and moved or renamed files are
recognized by content so their metadata is preserved.
The tray icon and quitting
Meguri lives in your system tray. Closing the window hides it to
the tray instead of quitting — the app keeps running so it can
reopen instantly. Click the tray icon to bring the window back.
To exit completely, choose Quit from the tray icon's
menu (on macOS, Cmd+Q also works).
Themes, language, and zoom
- Themes — pick from base16 themes (gruvbox, solarized,
nord, catppuccin, tokyo night, and more) in Settings. The entire UI
follows the theme, in light and dark variants.
- Language — the UI is available in English, 日本語,
Español, Français, 한국어, and 简体中文. Switch in Settings.
- Zoom — Ctrl + mouse wheel or
Ctrl + +/- to scale the UI;
Ctrl + 0 resets.
Where your data lives
Everything Meguri creates is kept in one place, separate from your media
(locations shown for Linux; on Windows it's under %APPDATA%,
on macOS under ~/Library/Application Support):
~/.config/Meguri/config.json — your registered
workspaces and settings.
~/.config/Meguri/roots/<id>/db.sqlite — the library
database for one workspace (tags, ratings, history, metadata).
~/.config/Meguri/roots/<id>/thumbs/ — generated
thumbnails.
Privacy: Meguri never connects to the internet. There is
no telemetry, no analytics, and no account. All features work fully
offline; the only network activity is a local server on your own machine
that streams your files to the app window.
Note: tags, ratings, and history stored in the database
may be lost when Meguri's internal data format changes between versions.
Your media files themselves are never at risk.
FAQ
A video won't play — what do I do?
Most formats play in-app, but a few codecs aren't supported by the
built-in player. Use Open externally in the detail view to
play the file with your system's default player.
I added files to my folder but they don't show up.
Click Scan in the header to re-scan the workspace. New
files are also picked up automatically the next time the app starts.
I moved/renamed files — did I lose my tags?
No. Meguri identifies files by their content, so tags, ratings,
favorites, and history follow a file across renames and moves within the
same workspace. Just run a scan after reorganizing.
Does Meguri change my files in any way?
No. Meguri only reads the folders you add. Thumbnails and metadata are
stored in its own app-data folder, never next to your media.
How do I uninstall cleanly?
Uninstall the app as usual for your OS, then delete Meguri's app-data
folder (see Where your data lives) if you also want to
remove thumbnails, tags, and settings. Your media files are unaffected.
