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.

29–40% of law firms have already experienced a breach

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.

Healthcare breaches average $7.42M per incident — IBM, 2025

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.

83% of workers recreate docs they cannot find — PwC

Vendor lock-in

When your knowledge system depends on a subscription, your institutional memory leaves when the contract does. Local means you keep everything.

27% of organizations have banned GenAI entirely — Cisco, 2024

Capabilities

Understand your own work beyond what keyword search can see.

StratoSort reads the content of your files — 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.

Setup

Running in three steps.
No terminal required.

01

Download the installer

One file for Windows or macOS. No Python, Docker, API keys, or command line.

02

Choose a model profile

Select a quality tier on first launch. StratoSort downloads models (2–5 GB, one time). GPU auto-detected.

03

Point it at your folders

Select directories to index. Search, chat, and visualize as soon as indexing completes.

Product preview

See StratoSort in action before you install.

A curated set of the most important clips: full workflow, setup, ingestion, review, semantic search, and document chat.

Part 09

End-to-end workflow demonstration

See the full journey from ingestion to AI-assisted organization and retrieval in one continuous flow.

Part 03

File discovery and AI analysis

Watch ingestion, document understanding, and early classification decisions happen automatically.

Part 04

Review queue and automation

Approve, adjust, and apply bulk organization actions with a human-in-the-loop workflow.

Part 06

Semantic search and graph visualization

Explore related documents by meaning, then navigate clusters and relationships in the knowledge graph.

Part 07

Conversational chat with context

Ask questions in plain language and get grounded answers from your own indexed documents.

Wizard 01

Choose local AI models

Select model profiles based on quality needs and available compute.

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 runs inference, vector search, and file operations in a single desktop process.

Local-first architecture

After model download, core processing stays on-device. In standard configuration, StratoSort does not send document content to third-party services.

In-process AI inference

LLM inference runs inside the application via node-llama-cpp, without requiring third-party AI APIs for core workflows.

Local vector search

Embeddings generated and stored on-device using Orama. Your semantic index is a local file you own.

Who it is for

Built for professionals who cannot afford
to hand their files to a stranger.

Legal

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.

42% of legal professionals spend 2–5 hrs/day on admin tasks — LEAP, 2026
Research

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.

90% of time creating "new" reports is spent recreating existing work — IDC
Healthcare

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.

Physicians are 2.43x more likely to burn out from EHR overload — JMIR, 2024
Financial Services

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.

Non-compliance costs 2.71x more than maintaining compliance — Gartner

Compliance outcomes depend on deployment, configuration, policies, and legal obligations. This page is product information, not legal advice.
