What is the Mochi file organizer?

A free, open-source, local-first macOS file organizer. It sorts Downloads, Desktop and chosen folders with deterministic rules, and optional AI can suggest destinations, but every move passes through review and the app never silently overwrites a file.

How does Mochi use Jev?

A direct TypeSafe Jev decision adapter handles closed-set classification, and BYOK settings let you point Mochi at Jev with the key stored in the macOS Keychain. The README says Jev is required for closed-set classification, alongside a generative fallback.

Does AI ever move my files on its own?

No. AI responses are treated as untrusted suggestions and pass through local validation, preview, journaling and execution boundaries; matching files enter Review before anything moves. Filesystem operations are never performed directly by a model.

What are the requirements?

macOS 13 for the SwiftUI menu-bar and dashboard app, Swift to build it, and a key for the AI providers you enable. Credentials are configured under Settings, AI & Privacy, with secrets stored in the macOS Keychain.

How do I build and run it?

Run swift build, then swift test, then swift run MochiApp. The benchmark command takes a JSON dataset and optional mock decisions keyed by candidate set hash: swift run mochi-benchmark dataset.json report.json decisions.json.

What does Mochi Pro add?

A provider-neutral gateway adapter plus a Vercel/Stripe backend with Supabase entitlement and quota storage. Setup, environment variables, Stripe events and deployment commands are documented in docs/MOCHI_PRO_BACKEND.md.

Mochi

A free, local-first macOS file organizer that sorts Downloads, Desktop and chosen folders with deterministic rules, review-before-move, crash recovery and undo. Optional AI, including a direct TypeSafe Jev decision adapter for closed-set classification, can suggest destinations but never touches the filesystem.

Works forJev for Classification Jev for Decision gating

Used inJev for Software & DevTools

Languages: Swift
Platforms: macOS Vercel AI Gateway
Capabilities: Open sourceRuns locally

Highlights

Deterministic rules run locally; AI can suggest destinations but cannot perform filesystem operations directly.
A direct TypeSafe Jev decision adapter handles closed-set classification, with OpenAI, Gemini, DeepSeek and Ollama adapters as generative fallbacks.
BYOK settings keep TypeSafe Jev and the other provider keys in the macOS Keychain, and Jev is the required model for closed-set classification.
Safety rails: FSEvents folder monitor, review before any move, durable operation journal, collision handling, crash recovery and safe undo.
Build and test with swift build, swift test and swift run MochiApp; a benchmark runner reports calibration and billed cost.

Quickstart

bash

swift build
swift test
swift run MochiApp

Watch out

README reviewed 2026-10-17; the README says the application is under active development and not ready to organize irreplaceable files, and hosted AI classification stays review-only until the exact model version passes the benchmark safety gate.

Jev at home: voice pipelines, Assist routing, and sentinels

Oct 16, 2026

How Home Assistant conversation agents, macOS voice pipelines, and an advisory sentinel put a fast typed decision in the loop — one call per utterance, thresholds in code, and a daily token budget.

Search visibility, audited by decisions

Oct 16, 2026

Jev-based SEO tools split the crawl from the call: deterministic crawlers count and parse, while typed judgments rank fixes, place internal links, score search results, and track AI-answer mentions — with costs and caveats attached.

Jev on the Gateways: Vercel, Workers AI, and OpenRouter

Oct 12, 2026

The request shape barely changes across surfaces; the surrounding contract does. When to call the API directly and when a gateway, a Worker binding, or a router entry earns its extra hop.
