AI for macOS · Local first · Your keys
Your AI, on your Mac.
The cloud only when it counts.
Optimaly runs open models natively on Apple Silicon and routes every task to the optimal model — escalating to Claude or GPT with your own API keys only when a task truly needs it, and showing you every dollar saved.

01 — Why Optimaly
Private by default.
Cheap by design.
Everything runs on your machine unless you decide otherwise. No accounts, no telemetry, no server between you and your AI.
ARadical privacy
Conversations live in a local database, keys in the macOS Keychain. Sensitive messages are detected and pinned to local processing — they never leave your Mac, even if you ask for cloud.
BNo subscription, no markup
Buy the app once. Cloud usage goes straight to your providers at their prices — we never proxy your tokens or take a cut. Local usage costs zero, forever.
CThe optimal model, every time
A router classifies each prompt and picks the cheapest model that can do it well, from an 8B model on your Mac to the frontier cloud — you set the cost/quality dial.
DQuality, verified
Local answers are quality-checked before you rely on them; weak or truncated ones silently retry on the cloud. You always see which model answered and why.
EMore than chat
Opt-in web search with cited sources, MCP tools so the model can act on your files and data, and batch processing over CSVs — all local, all free at volume.
FWorks offline
No internet? Local models keep working. Even the license check is cryptographic and offline — the app never phones home, because there is no home to phone.
Every request records what it cost and what it would have cost on a flagship cloud model. The dashboard shows the difference — per day, per model, per month.
02 — Under the hood
Engineering you can trust.
Native code, open models, and cryptography — not another Electron wrapper around an API.
Inference
Apple MLX
Runs any open MLX model from Hugging Face — Qwen, Llama, Mistral, DeepSeek, as large as your RAM allows — with an adaptive dual-server so switching tiers never reloads a model.
Core
Rust + Tauri 2
A real native app: fast startup, tiny footprint, no bundled browser engine per tab. The routing brain is compiled Rust, tested and linted to zero warnings.
Cloud reach
Claude, GPT & 300+ models
Direct Anthropic and OpenAI integration, or the whole market through one OpenRouter key — chosen per task from a live catalog with independent capability benchmarks.
Security
macOS Keychain + Ed25519
API keys never touch disk or logs. Licenses are Ed25519-signed and verified locally — no activation server exists.
Storage
Local SQLite
Your history is a file on your Mac. Export it, back it up, delete it — it's yours, and it never syncs anywhere.
Extensibility
MCP + web search
Model Context Protocol servers plug external tools into the local model. Web search (DuckDuckGo, Brave, or Tavily) is opt-in per message, with sources cited.
03 — How it works
You just chat.
The router does the accounting.
Every message finds its model in three steps, in milliseconds.
Classify
The prompt is typed in an instant: simple Q&A, summary, translation, code, deep reasoning. Sensitive content is detected and locked to local.
Route
Easy tasks hit the fast local model, harder ones the smart one. Only what exceeds local capability goes to the cloud — to the best-value model across your providers.
Verify
Answers below the quality bar retry silently on the cloud. Under each response: the model, the reason, the time, and the cost.
04 — Pricing

05 — Questions
Fair questions, straight answers.
What do I need to run it?
A Mac with Apple Silicon (M1 or later) on macOS 12+. Local models need disk space (4–20 GB per model) and RAM to match — the app adapts to what your machine can hold and guides the whole setup, no terminal required.
Do I need cloud API keys?
No. Local models work without any key, free and unlimited. Add an Anthropic, OpenAI, or OpenRouter key only if you want hard tasks escalated to the cloud.
Can you see my conversations?
No. Conversations stay in a local database on your Mac, keys stay in the macOS Keychain, and we run no servers and collect no telemetry. Read the privacy policy — it's short because there's nothing to disclose.
What happens when the trial ends?
The app asks for a license key. Buy once, paste the key, and everything unlocks permanently — the key validates offline.
Refunds and invoices?
Purchases are processed by our merchant of record (Lemon Squeezy), which issues a VAT invoice automatically and handles refunds per the policy shown at checkout.
