Search the way you remember
By meaning, face-name, attribute — “golden eyes”, “cat in grass” — or what is inside audio and documents.
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.

Demo: LatticeSearch answers searches like “the invoice from march”, “red flag photo” and “bell sound” in about 252 milliseconds, entirely on-device.
Watch
48 seconds: a half-remembered moment becomes the exact file — typed, found, opened. All on this device, nothing uploaded.
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.
Photos, videos, documents, and sound — all searchable by meaning, all on your device.
“The black cat with golden eyes.” Find any picture by the people, places, and things in it — and by face.
Describe a moment and jump to the exact second in an hour of footage, ready to clip.
Search inside PDFs, docs, and even screenshots by what they say — not what they’re named.
Find a sound, a song, or the exact words someone said — timestamped.
Concrete ways to find, understand, and look after the files already on your machine.
By meaning, face-name, attribute — “golden eyes”, “cat in grass” — or what is inside audio and documents.
Dates, places from EXIF, OCR text, and sound tags are added quietly, so tomorrow’s search knows more than today’s.
Finds duplicates and oversized files, then gives forgotten names meaning — like tuxedo-cat.jpg.

Semantic results arrive around a quarter of a second — measured at 25–75× faster than Windows Search.
Search and enrichment need zero GPU. The same engine works on a netbook and scales up when stronger hardware is available.
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.
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.
It uses roughly 20% of available resources, pivots between CPU and GPU, and never slows your work.
Your files, enrichment, index, and searches stay on the machine. Nothing leaves it — privacy is the architecture, not a setting.
You don’t remember filenames. You remember the red flag, the bell, the invoice from March. Search that way.
Results in milliseconds across 2.5 million files on one PC. The built-in file explorer opens folders faster than Windows Explorer does.
Type what you remember. “The invoice from march” works. So does a half-remembered phrase from inside the file.
100% on your device. Your files, searches, and private AI remain yours—and keep working offline.
Images by content. Documents by meaning in 100+ languages. Audio by sound. Video by timestamp. Speech by what was said.
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.
MCP server and CLI built in. Local agents stop grep-walking your disk and start asking for meaning.
One search box. Eight ways of remembering.
Find “the red flag photo” by what is pictured—not by the name it was saved under.
Search what a file says, not what it’s called. Works in 100+ languages.
“Bell sound” finds the ding — and the track that contains it, at the right second.
Search what’s on screen, then jump straight to the moment it appears.
Find what was said in recordings and calls — not just what was typed.
Every word inside every screenshot, read and searchable. OCR runs locally.
Tag Amy once, then ask for “photos of Amy” or simply “pictures of the family.”
The same picture in any size or format — caught even when the bytes differ.
Five human abilities, powered by one private LatticeSearch engine.
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 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 + videoDrag 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 pictureA 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 guessworkFind 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.
Find · recover · organise · actNo 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.
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.
Hover-scrub videos like YouTube. Play audio in place. Lightbox images. Skim text. All inside LatticeSearch — before a single external app launches.
An AES-256-GCM encrypted archive you can still search. Carry it on a Vault USB drive — your searchable library in your pocket.
Deleted something last month? Describe it — “the contract draft with the red header” — and restore it. Up to 90 days.
Byte-exact and visual duplicate detection finds the same file — and the same picture — hiding in five sizes and three formats.
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.
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.
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.
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.
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.
Coming. Windows ships first because that’s where file search is most broken. Mac and Linux builds are in development.
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.
Lattice Weave is our proprietary engine for combining meaning with file details like date, place, faces, attributes, and modality. It powers detailed searches while keeping files and indexes on your device.
