Search the way you remember
By meaning, face-name, attribute — “golden eyes”, “cat in grass” — or what is inside audio and documents.
LatticeSearch
The consumer edition of LatticeSearch
Find the file you can picture but can’t name.
You remember the beach, the red kite, who was there — just not the filename or the folder. So you scroll, and scroll, and give up. Type what you remember instead: LatticeSearch puts it on screen in about a quarter of a second, without a single file ever leaving your machine.
~252 ms semantic search, measured on-device · free to start · no account, nothing uploaded · Windows first — Mac & Linux coming. See what it finds ↓
Demo: LatticeSearch answers searches like “the invoice from march”, “red flag photo” and “bell sound” in about 252 milliseconds, entirely on-device.
Watch
See LatticeSearch in action
48 seconds: a half-remembered moment becomes the exact file — typed, found, opened. All on this device, nothing uploaded.
The problem you forgot you had
You own thousands of photos, videos, and files. Now try finding one.
You can picture last year’s photo exactly — the people, the place, the colours — but you have no idea what it’s called or which folder it’s in. Every scroll session costs you minutes; giving up costs you the memory. LatticeSearch makes everything on your computer searchable the way your memory actually works: by meaning, by face, by moment.
One search, everything you own
Find it by what’s in it — whatever “it” is.
Photos, videos, documents, and sound — all searchable by meaning, all on your device.
Photos
“The black cat with golden eyes.” Find any picture by the people, places, and things in it — and by face.
Video
Describe a moment and jump to the exact second in an hour of footage, ready to clip.
Documents
Search inside PDFs, docs, and even screenshots by what they say — not what they’re named.
Audio
Find a sound, a song, or the exact words someone said — timestamped.
What it does
It searches what you remember, then learns the details.
Concrete ways to find, understand, and look after the files already on your machine.
Gets smarter in the background
Dates, places from EXIF, OCR text, and sound tags are added quietly, so tomorrow’s search knows more than today’s.
Acts as your file custodian
Finds duplicates and oversized files, then gives forgotten names meaning — like tuxedo-cat.jpg.
Why it’s fast & private
Measured on the machine. Not promised from the cloud.

Semantic search
~252 ms
Instant means measured.
Semantic results arrive around a quarter of a second — measured at 25–75× faster than Windows Search.
LatticeSearch~252 ms
Windows Search25–75× slower
0 GPU
Runs anywhere.
Search and enrichment need zero GPU. The same engine works on a netbook and scales up when stronger hardware is available.
<1 ms
Grows with your library — 2.5 million files on one PC.
Exact results — 100% recall on filtered search — and under a millisecond per lookup even at a million files, where an ordinary scan stalls for a fifth of a second. Verified on a real 34,000-file index and a million-item projection.
~170 msper image
91×faster lookup
Background intelligence without the wait.
A two-stage classifier tags each image in about 170 ms on CPU — no GPU. At 50,000 records, the nested index makes attribute lookup 91× faster.
~20%
Adapts around your work.
It uses roughly 20% of available resources, pivots between CPU and GPU, and never slows your work.
Private by architecture
100%
On your device means on your device.
Your files, enrichment, index, and searches stay on the machine. Nothing leaves it — privacy is the architecture, not a setting.
Why LatticeSearch
Find by meaning, not by filename.
You don’t remember filenames. You remember the red flag, the bell, the invoice from March. Search that way.
Instant, actually
Results in milliseconds across 2.5 million files on one PC. The built-in file explorer opens folders faster than Windows Explorer does.
By meaning, not by filename
Type what you remember. “The invoice from march” works. So does a half-remembered phrase from inside the file.
Still here, still yours
100% on your device. Your files, searches, and private AI remain yours—and keep working offline.
Every modality
Images by content. Documents by meaning in 100+ languages. Audio by sound. Video by timestamp. Speech by what was said.
Powered by Lattice Weave
Our own engine weaves meaning together with your files’ details—place, date, faces, attributes—in a single query, and returns the true best matches, not approximations. “Golden-eyed cats in London” just works.
Your AI’s eyes
MCP server and CLI built in. Local agents stop grep-walking your disk and start asking for meaning.
Every modality
If it’s on your disk, you can find it.
One search box. Eight ways of remembering.
Images by content
Find “the red flag photo” by what is pictured—not by the name it was saved under.
Documents by meaning
Search what a file says, not what it’s called. Works in 100+ languages.
Audio by sound
“Bell sound” finds the ding — and the track that contains it, at the right second.
Video, with timestamps
Search what’s on screen, then jump straight to the moment it appears.
Speech
Find what was said in recordings and calls — not just what was typed.
Text in screenshots
Every word inside every screenshot, read and searchable. OCR runs locally.
Faces, with names
Tag Amy once, then ask for “photos of Amy” or simply “pictures of the family.”
Duplicates, pixel-level
The same picture in any size or format — caught even when the bytes differ.
Only in LatticeSearch
Remember less. Find more. Then get things done.
Five human abilities, powered by one private LatticeSearch engine.
Names turn memory into search
Name a face once. From then on, everyday requests like “show me Amy” work naturally—especially helpful for families, older users, and anyone who finds folders hard to navigate.
“Pictures of the family”One private AI sees, reads, hears, and watches
One on-device brain understands documents, the words inside screenshots and PDFs, what is pictured, what is heard, and what happens across a video. No separate tools, no cloud hand-off.
Text + images + audio + videoCrop to source
Drag in a cropped detail—a face, logo, product, or corner of a screenshot—and LatticeSearch finds the full original image on your machine.
A fragment becomes the full pictureThe right install for this PC
A 48-second setup wizard checks your spec and chooses the leanest build for a netbook or the fullest experience for a powerful PC. Fast, capable, and never a resource hog.
48-second setup · no hardware guessworkRecover what vanished. Act on what remains.
Find and restore deleted files, organise and rename the rest by meaning, then let the assistant complete web or OS tasks—with you in control of every consequential action.

Private by architecture
Nothing ever leaves your machine.
No cloud. No account required. No telemetry on your content. LatticeSearch works 100% on your device—nothing to leak, nothing to train on, and no service holding your memories hostage. Your files, your index, your searches: still here, still yours.
Works fully offline
No account required for search
No NPU or new PC needed
Knowledge graph
See how your files relate.
The graph isn’t dots and labels. Nodes are the content — thumbnails you can see, audio you can play, text cards you can read — connected by meaning. Follow a project across folders, drives and years.
Media previews
Know it’s the right file before you open it.
Hover-scrub videos like YouTube. Play audio in place. Lightbox images. Skim text. All inside LatticeSearch — before a single external app launches.
More than search
Tools that respect your disk.
Vault
An AES-256-GCM encrypted archive you can still search. Carry it on a Vault USB drive — your searchable library in your pocket.
File recovery
Deleted something last month? Describe it — “the contract draft with the red header” — and restore it. Up to 90 days.
Reclaim space
Byte-exact and visual duplicate detection finds the same file — and the same picture — hiding in five sizes and three formats.
AI access
Give your local AI agents eyes.
LatticeSearch ships with an MCP server and a CLI. Instead of grep-walking directory trees, your agents ask one question and get the right files back — measured at 44× fewer tokens and 12× faster than grep-walks.

Fair notes: Everything is superb at instant filename search — that’s all it does. Cloud drives search well, but on their machines, not yours.
FAQ
Fair questions, straight answers.
Does it really work offline?
Yes. Indexing, search, previews, the knowledge graph, the Vault — everything runs on your machine. There is no server component. Disconnect the network and nothing changes.
What do you collect about my files?
Nothing. Your files, your index and your queries never leave the machine. There is no account requirement and no content telemetry — we couldn’t read your data if we wanted to, because it never reaches us.
Which plan should I choose?
Free covers fast essentials on one machine. LatticeSearch Personal adds full understanding across text, images, and audio. LatticeSearch Pro adds face-name search, advanced lenses, deeper recovery, workspaces, and permissioned web and OS actions. Pay monthly or save with yearly billing; power users get Weave, and teams use LatticeSearch Weave for business. Cancel anytime — it gently returns to free Lite and you keep your files and your index.
What does it need to run?
A normal 64-bit Windows 10 or 11 PC. The installer checks your machine and selects the right build automatically—from a lean netbook setup to the fullest experience a powerful PC can run. No NPU and no new hardware required.
Mac and Linux?
Coming. Windows ships first because that’s where file search is most broken. Mac and Linux builds are in development.
How is this different from Everything?
Everything matches filenames, instantly, and it’s excellent at that. LatticeSearch is just as instant but helps you find by meaning, not by filename: image content, document text in 100+ languages, audio, speech, video, and OCR. Different tool, different job.
