Your files. Your AI. Your machine.
A local AI knowledge engine for professionals who cannot afford to hand their files to a stranger. Search by meaning. Chat with your documents. Everything runs on your hardware.

The problem
Cloud AI raises avoidable risk when your files are the liability.
When sensitive documents are indexed by third-party services, control and auditability can drop. In regulated workflows, that can increase compliance exposure and remediation cost.
When third-party services process case files, privilege, access, and disclosure risk must be actively managed.
Attorney-client privilege
Consumer AI terms and data flows can create privilege and confidentiality risk for legal work, depending on jurisdiction and controls.
Regulatory exposure
Frameworks such as HIPAA, FERPA, CJIS, ITAR, and SOC 2 require strict data-handling controls. Cloud indexing often requires additional safeguards, contractual terms, and configuration to align with those obligations.
Keyword search fails
Professionals succeed only 56% of the time when searching for information. The rest is wasted — or the document gets recreated from scratch.
Vendor lock-in
When your knowledge system depends on a subscription, your institutional memory leaves when the contract does. Local means you keep everything.
Capabilities
Understand your own work beyond what keyword search can see.
StratoSort reads the content of your files — text, images, and now audio and video — not just filenames — using AI that runs entirely on your hardware.
Semantic Search
Find files by meaning, not exact text. Query "non-compete clause" and surface relevant documents even when those words are not in the filename.
Document Chat
Ask questions about your files in plain language. StratoSort retrieves relevant context and generates grounded answers from your own documents.
Knowledge Graph
Visualize how your documents relate. See clusters, connections, and semantic neighborhoods across your entire file archive.
File Routing
Define categories in plain language. When new files arrive, StratoSort reads their content and moves them where they belong automatically.
Vision and OCR
Receipts, screenshots, scanned PDFs — computer vision and OCR read images and categorize them alongside your text documents.
Full Undo / Redo
File moves and renames are reversible with a reviewable action history, so you can inspect and roll back changes confidently.
Audio & Video Transcription
Search meeting recordings, voice memos, and video by what was said. Whisper runs locally on your machine — transcripts are indexed alongside your documents, never uploaded.
Hands-off automation
Pick the files once.
StratoSort handles the rest.
Choose the folders you care about one time. From there, StratoSort scans new files, classifies them, and routes them into smart folders automatically.
- Select once
- New files arrive
- Smart folders
No dragging. No renaming. No manual sorting. After setup, new files are read in the background and routed into the folders you defined.
Hands off — routing in progress
The cost of digital disorganization
The numbers behind the problem you already feel.
Setup
Running in three steps.
No terminal required.
Private beta · installer ships to approved testers
Download the installer
One file for Windows or macOS. No Python, Docker, API keys, or command line.
Choose a model profile
Select a quality tier on first launch. StratoSort downloads models (2–5 GB, one time). GPU auto-detected.
Point it at your folders
Select directories to index. Search, chat, and visualize as soon as indexing completes.
Architecture
Privacy is not a setting.
It is how the system is built.
There is no toggle to turn off cloud sync. There is no cloud layer. StratoSort analyzes content, maintains a local search layer, and manages file actions inside one desktop workflow.
Local-first architecture
After model download, core processing stays on-device. In standard configuration, StratoSort does not send document content to third-party services.
On-device AI analysis
Document understanding runs inside the app on your hardware, without depending on third-party AI APIs for core workflows.
Local search and organization
Your search index and organization logic stay on-device, so your files and retrieval layer remain under your control.
Who it is for
Built for professionals who cannot afford
to hand their files to a stranger.
Find the clause across 10,000 files.
Search case files, contracts, and discovery materials by meaning. Surface relevant precedent without remembering filenames while keeping analysis on infrastructure you control. Search depositions and recorded interviews by what was said, not just filenames.
Query your literature archive in plain language.
Ask "which papers discuss transformer attention applied to genomics" across years of PDFs. Get grounded answers with source citations from your own collection. Query recorded interviews and lecture audio alongside your PDF library.
Organize clinical documentation with tighter data boundaries.
Index and search patient notes, protocol documents, and compliance records on local infrastructure. Teams should validate HIPAA and vendor-risk requirements for their environment before deployment.
Surface the version, the source, the number.
Analysts working with earnings reports, SEC filings, and internal models can query across document types. Find the data point without opening fifty tabs.
Compliance outcomes depend on deployment, configuration, policies, and legal obligations. This page is product information, not legal advice.
