Mahout – Tasker+AI+N8N

Mahout, an open-source Android workflow automation app from developer ankurCES, combines Tasker-style device automation with n8n-style visual workflows and on-device AI, running all AI either through Google's Gemini Nano on the phone or the user's own API keys with no cloud subscription or account. The app organizes roughly 90+ nodes across nine lanes — including triggers, data, logic, AI, actions, and apps — and supports 11 OpenAI-compatible providers plus the Claude SDK and Gemini Nano. Mahout is distributed as source on GitHub, requiring Android Studio Koala+, Java 17, Gradle 8.7+, and the NDK for Room schema export.

On-device workflow automation for Android — n8n meets Tasker. Every device capability is a node . Wire any node to any other node. Build automation workflows visually, or describe what you want and let Build with AI draft it. Run them manually, on schedules, or from real-world triggers — notifications, location, sensors, media, and more. All AI runs on-device Gemini Nano or through your own API keys — no cloud subscription, no account, your data stays on your phone. | Dashboard Run counts, AI spend, system health | Workflows All your automations, one list | | Editor Drag-drop DAG canvas | Chat Operator AI assistant, token-by-token streaming | | Build with AI Describe a workflow, AI drafts it | Knowledge On-device RAG index | | Skills Agent skills + enable switches | Permissions One-tap grant-all stepper | Every node is one self-contained Kotlin object : Node — a spec params, inputs/outputs, gates, timeout plus an execute ctx, input method. Nine lanes organise ~90+ nodes: | Lane | What it contains | |---|---| | Triggers | Manual, schedule, notifications, sensors, location, calendar, webhooks, charging, proximity, system broadcasts | | Data | HTTP requests, device info, media metadata, knowledge search, variable store | | Logic | Conditions if/else , loops, JS eval, text & math, merge, wait/delay | | AI | Ask AI, Classify, Extract, Agent tool-using loop , MCP tool/resource, Decision routing | | Actions | Notifications, system settings torch, DND, Wi-Fi, Bluetooth , send intents, file writes, playlist entries, knowledge ingest | | Apps | Deep-link launches, shell commands, JS runtime, workspace file I/O, UI automation Accessibility | A draggable, zoomable DAG canvas. Drop nodes from the palette, wire them together, configure params. The same params that drive the UI also drive Agent tool schemas, templating, validation, and log redaction. Fields are wired through a simple syntax that feels like a templating language: {{title}} {{meta.artist}} {{items 0 .name}} ← current item fields {{$node.HTTP.body.x}} ← upstream node's first output {{$vars.counter}} ← global variable {{$now}} {{$date}} {{$time}} ← built-in values {{field ?? "default"}} ← fallback when missing An approval-gated AI assistant that manages your workflows, runs, knowledge, skills, and a coding sandbox — all from a natural-language interface. Four permission modes: - Plan — no tools, read-only thinking - Ask — per-call approval - Auto — risk-based: safe actions read/search never ask, coding actions shell/JS ask, destructive actions delete, UI automation always require approval - Bypass — time-limited full automatic, with a kill switch The chat streams token-by-token and retains a turn history with tool-use results. 11 OpenAI-compatible providers OpenAI, OpenRouter, MiniMax, Gemini, Grok, DeepSeek, Mistral, Groq, Together, Ollama, Custom + Claude SDK + Gemini Nano on-device . All through your own keys — no Mahout cloud costs anything. On-device RAG: index documents, folders, URLs, pasted text, Notes, and Playlists. Room FTS4 storage with BM25 ranking. The Agent can search it with knowledge search . Connect remote MCP servers stdio or SSE and expose their tools to the Agent or as plain workflow nodes. Running workflows control suspend, cancel, resume , background host monitor, second-opinion, risk assessment, and System One decision engine — all from the Dashboard.
