“The beach video from last year with loud splashing.” “The photo of that circuit board with the part numbers.” “The part of the meeting about quarterly revenue.” Describe it the way you remember it, and Threebrook Seek takes you straight to the photo, the exact seconds, the right page. Everything runs on your own PC. Nothing is uploaded.
Personal edition is free · 14-day Pro trial on first install · Standard installer about 1 GB (models included)
The real app
Screenshots are from the real Threebrook Seek, in English. The photos and videos in them are illustrations we drew ourselves.
Who it’s for
Files pile up. You remember what it looked like or what someone said, just not the folder or the file name. In moments like these, one sentence is enough.
PARENTS
Tens of thousands of files exported from your phone, all named VID_2024… Finding “first steps” means scrolling until your eyes hurt.
“baby’s first steps”
Jumps to the exact seconds in the video · Trips and birthdays grouped into Moments
FAMILY ARCHIVISTS
Hundreds of scans named Scan_0001 to Scan_0420, with no dates and no tags. All you remember is that your grandparents stood in front of the old house.
“grandma and grandpa in front of the old house”
Search by what’s in the picture · Reads handwriting on the back · Find similar and duplicates
PEOPLE IN MEETINGS Pro
A two-hour recording, a forty-slide deck. Your manager asks, and you only remember it came up during the revenue part.
“the part of the meeting about quarterly revenue”
Recordings line up with each slide · Jump to where a slide was discussed · Export draft minutes
VIDEO CREATORS
Halfway through an edit you need a few seconds of “waves on rocks, no people”. The clips are named A001 to A480, so you scrub through them one by one.
“waves hitting rocks, no people”
Video search to the second · Right-click to export just that clip · Drag it into your editor
ENGINEERS & DESIGNERS
Thousands of photos of boards, whiteboards and handwritten specs. The one you need says STM32F407 somewhere, and that’s all you recall.
“photo of a circuit board with part numbers”
Text in photos and screenshots is searchable · Quotes for exact matches · Pro also searches code
STUDENTS & RESEARCHERS
A semester of lecture videos and slides, plus hundreds of PDF papers. You want the few minutes on Bayes’ theorem.
“where the professor explains Bayes’ theorem”
Search what was said in lectures and written on the board · Find PDFs and slides by content
Three brooks, one search box
Threebrook (三溪, “three brooks”) is the small town our team lives in. Threebrook Seek brings together what’s in your pictures, what’s in your audio and what’s in your text, and pours them into one search box.
Photos, video frames, and pages of PDFs and slide decks. Find them by what you saw, with no file names to remember and no tagging first.
my kid riding a bike for the first time
whiteboard covered in flowcharts
Audio in recordings and videos. Speech is transcribed, and it also recognizes applause, laughter, waves, fireworks and more.
everyone singing together at the party
the call where someone said “ship it next Wednesday”
Word, Excel, PDF, web pages, e-books, email, code, plus the text inside screenshots and photos. It finds things that mean the same, not just the same words.

Try it
Below are 16 sample files: photos, videos, recordings, screenshots and documents. Pick a sentence to see what comes up and which second a video starts from.
The demo uses illustrations and pre-arranged results. This page doesn’t go online or run any model, so it only knows the sentences above. Once installed, you can search your own files in your own words.

To the second
Once a video or recording is found, there’s no more scrubbing. The highlighted part of the timeline is the stretch closest to what you said. Click it and playback starts there.
Videos are indexed in segments by picture and sound; recordings are transcribed sentence by sentence.
Each segment is scored when you search, and the closest ones light up on the timeline, usually to within 2–10 seconds.
Right-click to export just that part as a short video or audio clip to send to someone.
Privacy
The AI models that recognize pictures, transcribe audio and read documents are installed on your PC. It works the same with no internet at all.
The Personal edition contains no networking code: no uploads, no analytics, no ads. Even “check for updates” just opens our download page in your browser.
The index, thumbnails and recognized text are stored encrypted, with the key protected by your Windows account.
Face grouping and place lookup are off by default and ask first. Turn them off and the related data is deleted too.
It only reads the folders you choose and never moves or changes your files. When uninstalling, you decide whether to delete the index.
Safe for lawyers, doctors, accountants and anyone whose files can’t go to the cloud. This website has no analytics or third-party trackers either: we don’t know who you are, and we don’t need to.
After you find it
Call it up with a shortcut from any app, then drag results straight into chat, Word or File Explorer.
Photos and videos from trips, parties and holidays are grouped into Moments, with the seconds of applause, laughter or fireworks picked out.
Recordings find their matching deck and line up slide by slide. Export draft minutes with the transcript under each slide.
Take a screenshot and press Ctrl+V in the search box to find similar photos. Pick a sound clip to find ones that sound alike.
Save a search as a collection, and new photos that fit it join on their own.
Mark a folder private and it only appears in search and the gallery after Windows Hello.
Tuanzi
Tuanzi (团子, “little dumpling”) eats the folders you drag to it: cheeks puffing while it indexes, eyes following the files as they fly in. Double-click it to search. The longer you use it, the more looks it grows, and now and then it digs up an old photo you’d forgotten. Don’t want it? Turn it off in Settings.
Editions
Your first install includes a 14-day Pro trial. When it ends you’re on Personal, and everything already indexed stays. Pro is a one-time purchase, not a subscription, with a year of free updates.
