On-Device AI Agents & Automation
We tested and ranked 27 On-Device AI Agents & Automation apps for Mac — updated August 2026.
Every app here was run on our own Apple-silicon Macs and scored on the published rubric — capability, craft, privacy, value. We watch the network while we test. How we rank →
You need software that goes beyond answering questions — it clicks buttons, files documents, triages email, or kicks off multi-step workflows while keeping your data on the Mac in front of you. This category covers 27 apps that act as autonomous assistants on your device: web-scraping bots driven by Apple Intelligence, file agents powered by Ollama, email classifiers that never phone home, and full reasoning-orchestration platforms that chain local LLMs together offline. We evaluated each on Capability, Craft, Privacy, and Value. The range runs from free single-purpose utilities that turn a natural-language prompt into a calendar event to $119 enterprise-grade orchestrators with policy reasoning and human-in-the-loop safety. Several apps are hybrids — local by default, with optional cloud APIs you can leave turned off. The ranked list follows.
The ranking — all 27
Sockpuppet AI
Kammerath Technology UGTurns repetitive website tasks into multi-step automations — clicking, filling forms, logging in — with Siri and Shortcuts integration baked in. AI content processing runs locally through Apple Intelligence in a serverless, no-data-collection design.
” Its AI functions run locally on your device, without an internet connection, using Apple Intelligence — test note
BonzAI - Local AI Agent
Thomas LECONTEPairs true local inference via llama.cpp with MCP tool-calling, file and image analysis, and Shortcuts automation. Supports a wide range of open-source GGUF models — Gemma, Qwen, Phi, Mistral, Llama, DeepSeek — and lets you reach for cloud APIs only when you choose.
” BonzAI relies on llama.cpp to run efficient GGUF models on Apple devices — test note
PulseCraft Studio
Mithila MuralidharanA full 3D scene builder and keyframe animator whose conversational AI assistant creates objects, lighting, and animations by chat — and can run entirely on-device on Apple Silicon for privacy.
” run models entirely on-device with Apple Silicon for complete privacy — test note
Lokei Studio
Justin PattersonA local AI workspace that runs multi-step Missions and scheduled Watchers through approved MCP and custom tools. Supports Apple Intelligence, Ollama, and LM Studio as backends with no Lokei cloud or account required.
” Use Apple Intelligence on supported Macs, fully on device. Or connect to Ollama, LM Studio, or another local model server; Lokei does not run a cloud AI service — test note
TealKit: Private AI Agents
Laszlo SchafferDelivers genuinely autonomous, cron-schedulable agents with MCP extensibility, local DuckDB document indexing, and SSH/script automation. Runs local Ollama models with no vendor cloud touching your data.
” or local Ollama models; Index local documents ... into local DuckDB; NO TealKit Cloud servers for your private data — test note
PawScope
跃洋 王A file-focused agent that actually sorts, renames, and summarizes documents on disk — plus arXiv research — with per-action approval so it never acts without your sign-off. Runs locally via Ollama by default.
” Use local models (Ollama) for complete privacy — test note
Sorto: AI email client
ehsan azishAn email client that classifies every incoming message into eight smart categories using only Apple's Foundation Model, keeping all content on-device. AI-assisted replies are built in.
” Apple's Foundation Model runs entirely on your device... There's no server to send it to. — test note
Nova Key
Om GandhiA Spotlight-style command palette that uses Apple's on-device Foundation Models to turn natural-language input into reminders, calendar events, and clipboard summaries — all AI logic handled privately on the Mac.
” powered by on-device Foundation Models, meaning all AI logic is handled privately on your Mac — test note
Inbox AI
Andre FoekenBuilds real multi-step workflows that extract tasks from mail, screenshots, and audio, then route them to Reminders, Notion, Obsidian, or Tana. Mail processing and transcription happen on-device, with local Ollama supported alongside cloud models.
” privacy-first on-device AI. Mail processing and transcription happens fully on-device. Inbox AI supports Ollama, OpenAI, and Anthropic AI models. — test note
causa
Black Forest Al GmbHA reasoning-orchestration platform for power users and enterprises that runs and hot-swaps multiple LLMs fully offline on Apple Silicon, with policy reasoning, chain-of-thought, and human-in-the-loop safety guardrails.
” on-device inference that manages and runs AI models entirely offline; 100% Privacy by Design - causa runs entirely offline — test note
How to choose On-Device AI Agents & Automation for Mac
First, decide what kind of actions you need automated. Some apps focus on a single domain — Sorto triages email, PawScope organizes local files, Nova Key creates reminders — while others like BonzAI and TealKit offer broad tool-calling with MCP, SSH, and Shortcuts integration. Pick the narrower tool if your task is clear; pick a platform if you want extensibility. Second, check the model backend. Apps built on Apple Intelligence (Sockpuppet AI, Sorto, Nova Key) require supported hardware but need zero setup. Apps that connect to Ollama or LM Studio (BonzAI, Lokei Studio, TealKit) give you model choice — Gemma, Qwen, Llama, DeepSeek — at the cost of installing and managing those servers yourself. causa runs its own fully offline inference engine. Match the backend to your comfort level and your Mac's memory. Third, weigh the privacy posture against your needs. Pure-local apps like Sockpuppet AI and causa never reach the network; hybrid apps like BonzAI and TealKit can connect to cloud providers, but only when you configure them to. For sensitive workflows, confirm whether cloud access is opt-in or opt-out. Finally, consider maturity: most apps here have very few ratings, so trial them on non-critical tasks first.
Questions people ask
What can an on-device AI agent actually do on my Mac compared to a regular chatbot?
Instead of just generating text, these agents take real actions. Sockpuppet AI clicks through websites and fills forms. PawScope sorts, renames, and summarizes files on disk. Inbox AI extracts tasks from email and screenshots and routes them to Notion or Reminders. The key difference is multi-step execution with tool use — the AI decides what to do next, performs it, and confirms the result, all running locally rather than on a remote server.
Do AI agent apps for Mac work without an internet connection?
Several do. Apps powered by Apple Intelligence — Sockpuppet AI, Sorto, Nova Key — run inference on-device with no network needed. causa operates fully offline with its own reasoning engine. Agents that use Ollama or LM Studio, like BonzAI and Lokei Studio, also stay offline once models are downloaded. Hybrid apps such as TealKit and Inbox AI process locally by default but offer optional cloud model connections you can disable.
How much memory does my Mac need to run a local AI agent?
Apps using Apple Intelligence work on any supported Apple Silicon Mac with no extra memory demands. Ollama-based agents run comfortably with 16 GB of unified memory for 7B-parameter models; causa recommends 16 GB as a minimum for its multi-model orchestration. If you plan to hot-swap larger models or run concurrent agents, 32 GB gives more headroom. No discrete GPU is required — Apple Silicon's integrated GPU and Neural Engine handle the inference.
