Local AI Assistant for Mac
Local-first, not fully offline. GuideLayer runs on your Codex subscription or Claude API key before any metered fallback.
Reviewed July 21, 2026. GuideLayer publishes this page; we mark our own product clearly and stick to facts we can re-check on each vendor's site.
"Local AI" gets used for everything from fully offline Llama installs to chat apps that happen to have a Mac client. The details matter.
GuideLayer is local-first: it runs on your Mac, stores encrypted data on your Mac, and can route inference through your Codex subscription, or Claude API key, the same privacy frame as our private AI assistant page.
Not air-gapped. Capture stays on demand. Your machine, the route you choose, your Privacy Center settings, and an Ability Map that lives on the Mac instead of a vendor chat archive. Pair with screen-aware AI when you need on-screen guidance.
What actually works
Codex or Claude API key first
Primary inference path uses Codex or a Claude API key already on the device. No extra model bill from GuideLayer for daily use.
Data stays on device
Saved tutorials, encrypted conversations, and Privacy Center prefs live locally. Not a vendor cloud account.
Apple Silicon native
Signed, notarized Mac app built for Apple Silicon. Menu-bar native, not a web wrapper.
Optional API fallback
Metered cloud APIs available when you need them. Not the default path for every query.
What local-first means here
Fully offline AI (Ollama, LM Studio) keeps everything on device but can't match frontier models for complex screen reasoning. Cloud-only assistants get the models but want your context in their cloud. GuideLayer sits between: frontier models through your Codex subscription, or Claude API key, with screen context captured locally on demand and ability stored on your Mac.

Workflow examples
Daily assistant without a new subscription
You already pay for Codex, or you bring a Claude API key. You don't want another AI meter.
- 01Sign in with what's on the Mac.
- 02Use voice and screen guidance through that path.
- 03API fallback only when you explicitly need it.
Tutorials stored on the machine
Team walkthroughs shouldn't live in a vendor's cloud by default.
- 01Record and save tutorials locally.
- 02Export Markdown or PDF to share however you want.
- 03Replay from the Mac without re-uploading to a platform.
Evaluating vs Ollama or cloud chat
You're deciding between local models, cloud chat, and something screen-aware.
- 01Ollama: best for offline text/code, no screen guidance.
- 02Cloud chat: best for reasoning, weak on seeing your UI.
- 03GuideLayer: screen-aware, local-first storage, your own providers.
Local AI on Mac isn't one thing. For screen guidance with your own providers, verified results, and an Ability Map that stays on the Mac, that's the lane GuideLayer occupies. See private AI assistant for the trust model.
