Knotwork

Knotwork is an AI agent that runs its model on the phone. Instead of a prompt box wired to somebody's API, every conversation runs through a pipeline you can open and edit: a graph of typed nodes - input, on-device LLM, optional cloud LLM, tool call, routing, decomposition, evaluation, clarification, output. When a step wants to do something destructive or sensitive, it stops and asks you first - including in the background, where the confirmation arrives as a notification. WHAT IT DOES - Runs on your device. On-device inference through LiteRT-LM, with optional GPU acceleration; CPU-only works, just slower. Cloud providers (OpenAI, Anthropic, Google Gemini, DeepSeek, OpenRouter, Groq) and a server you run (Ollama or any OpenAI-compatible one) are optional and use your own key. - You build the behaviour. A drag-and-drop editor with pan and pinch-zoom, snap-to-grid, auto-layout, inline validation and a run-trace overlay, across 14 node types. Prompt variables such as $DATE, $TIME, $TOOLS, $MODEL and $MEMORY_SUMMARY render fresh on every run. - Tools, gated by you. Built-in tools and external servers through the Model Context Protocol (MCP). By default every sensitive or destructive call stops for explicit confirmation, enforced where the tool executes, not merely suggested to the model. - Reaches you from outside the app. A share target, launcher shortcuts and a Quick Settings tile run your chosen pipeline over shared text or images. Triggers (time, charging, Wi-Fi, network) fire a pipeline on their own and report back. Every entry surface stays inert until you bind a pipeline to it. - Remembers what matters. Long-term memory with semantic retrieval over past conversations, automatic fact extraction, search and export. WHO IT IS FOR It is for the person who already runs Tasker, Obsidian, Home Assistant or a local model on their own hardware, and who wants to know exactly what their agent does with their data. PRIVACY There is no account, no sign-in and no server of mine. Inference runs on the phone, so a normal conversation never leaves it. Data goes out only along paths the privacy policy lists, each off until you switch it on - except the built-in Wikipedia lookup, on by default. Usage statistics stay on the device and are never transmitted; a build-time check fails the build if any network dependency reaches that code. The database - chats, memory, run traces - is SQLCipher-encrypted, and API keys are sealed under an Android Keystore key. Crash reporting is opt-in, off by default, and absent entirely from the FOSS build. KNOWN LIMITATIONS This is a pre-release. The public surface, the settings layout and the on-device storage formats can still change between versions. - English interface only. - Android 14+ and about 2 GB of free RAM - the memory is the real constraint. - On some phones the screen freezes while the model runs on the GPU; switch it to CPU. - Shared pipeline files are not a compatibility contract before 1.0. Keep the original. - Background runs need the battery setting on Unrestricted. Without it Android reclaims the process in about ten seconds - the platform's rule, not a bug, but until you grant it background pipelines will not run. - Cloud failure behaviour differs by provider: detection of a stream that dies mid-answer is enabled only where it was measured. - Other apps' AppFunctions are out of reach - Android keeps the permission to call one for system apps. The local catalogue is what ships, plus whatever you connect over MCP. - One maintainer, no company behind it.
