Aitopus vs Mult Controller

Powerful AI without giving up your data. Chat privately with AI on your Mac, get answers from your documents, or search the web with sources you can check. Type your thoughts or use voice dictation, and choose between models that run offline and leading cloud models connected through your own API keys. No Aitopus account, no tracking, and no cloud sync. CHAT WITH YOUR DOCUMENTS - Ask questions, summarize long reports, and compare information across files - Attach PDFs, Word, Excel, and PowerPoint files, text, and source code - Check the sources in your documents and ask follow-up questions - Documents are indexed locally on your Mac SEARCH THE WEB, CHECK THE SOURCES - Enable web search per chat with compatible models to get current information - Follow inline citations and browse the sources behind an answer SPEAK YOUR THOUGHTS - Dictate messages using on-device speech recognition on supported Macs and languages - Review and edit the text before sending - Your dictation audio stays on your device and is never stored by Aitopus RUN AI OFFLINE ON YOUR MAC - Discover models like Gemma, Qwen, and OpenAI's gpt-oss in a curated catalog - Find models that fit your Mac, with guidance based on available memory - Run local models with Metal acceleration, built for Apple silicon - Once your models are downloaded, chat and work with documents offline CHOOSE YOUR CLOUD MODELS - Connect your own API keys for OpenAI, Anthropic, Google, Mistral, Z.AI, and xAI - Switch between local and cloud models within the same conversation - API keys are kept in your device's secure storage A WORKSPACE THAT KEEPS UP - Keep separate conversations with full history, message editing, and branching - Read formatted answers with code highlighting and math rendering - Adjust reasoning, context, and response length with supported models - Export and import conversations as portable backups - Available in English, French, German, Spanish, Italian, Portuguese, Greek, and Turkish PRIVATE BY DEFAULT, ONLINE BY CHOICE Your conversation history and documents are stored locally on your Mac. Offline chat with local models keeps your prompts and documents on your device. If you choose a cloud model, messages and relevant attachment content go directly to that provider. Optional web search sends search queries to an external search service; queries may include details from your conversation. You control access to these online features. FREE, WITH NOTHING TO UNLOCK Aitopus is free, and its core will stay free forever. No Aitopus subscription, no ads, no data harvesting. Cloud providers may charge separately for API usage. Local model availability and performance depend on your Mac's memory. Cloud models and web search require an internet connection. AI can make mistakes, so verify important information.

Mult Controller is a canvas-based OSC and MIDI controller for iOS. Build your own control surface — place knobs, pads, sliders, and sensor-driven widgets on an open canvas, then lock it and play. CANVAS AND SESSIONS Name a session, choose OSC or MIDI, set a destination, and a blank canvas appears. Toggle edit/performance mode with the lock button. In edit mode, drag and configure components freely. In performance mode, the layout freezes and controls go live. Sessions save automatically as JSON files visible in Files.app under Mult Controller → Sessions/. Run multiple sessions simultaneously — each has its own transport destination. 11 BUILT-IN COMPONENTS Knob — rotary dial, continuous output. Slider — linear fader in Small, Medium, and Large. Button — momentary or latch; fires MIDI Note or CC. Switch — persistent on/off toggle. XY Pad — two-axis touchpad, two independent values. Physical Pad — XY pad with real momentum physics; release and the point coasts. Image Pad — samples RGB from a photo; streams red, green, blue as three values. Gyro Pad — device tilt drives XY output automatically, no touch needed. AR Coordinates — ARKit tracks position in space and emits X, Y, Z continuously. Compass — magnetometer outputs heading in degrees (0–360). Envelope Follower — microphone amplitude drives a control channel in real time. OSC Sends OSC 1.0 over UDP. Type a destination IP and port — no pairing needed. Broadcast mode reaches every device on the subnet. Choose a coalescing rate of 30, 60, or 120 Hz. Compatible with Ableton Live, Max/MSP, SuperCollider, QLab, TouchDesigner, Resolume, and any OSC-capable software. MIDI Switch a session to MIDI and components send over CoreMIDI 2.0. Connect via Bluetooth MIDI or Network MIDI over Wi-Fi. Each component has its own channel, CC number, message type, note, and velocity — fully configurable per control. PERMISSIONS MultOSC requests permissions only for the components that need them. iOS will prompt you the first time a component is activated. To grant or revoke permissions manually, go to Settings → Privacy & Security on your device. Camera — required by AR Coordinates to run ARKit world tracking. Without it, the component places on canvas but outputs nothing. Microphone — required by Envelope Follower to read amplitude. Without it, the output stays at zero. Bluetooth — required to discover and pair BLE MIDI instruments and controllers. Local Network — required for OSC UDP packets and Network MIDI over Wi-Fi. Without it, no messages leave the device. Location (When in Use) — required by Compass to read magnetometer heading via CoreLocation. Without it, the needle stays at 0°. If a permission is denied, the affected component stays placed on the canvas but its output freezes. Re-enable the permission in Settings and the component resumes immediately — no restart needed. PRIVACY MultOSC collects no data — no analytics, no crash reporters, no usage tracking. Session files are plain text in your Documents folder. The only outbound traffic is the OSC and MIDI you configure yourself.
