Synaplan is your private AI assistant that talks to leading AI models AND your own knowledge. Ask questions in plain language and get answers grounded in your own documents, not just the model's training data. Upload files into knowledge folders and chat with them — reports, manuals, notes, research — and get answers with the sources they came from. WHY SYNAPLAN • One assistant, many models — pick the AI that fits the task. • Chat with your documents (RAG): upload files and ask across them. • Voice input: dictate instead of typing. • Image generation: create visuals right in the chat. • Tools & knowledge folders to organize how you work. • Private by design: your data flows through the server you choose. BUILT FOR YOU • Connect to Synaplan.com or to your own self-hosted Synaplan server — you decide where your data lives. • Clean, fast, native experience: dark mode, offline-aware, share and save results. • Available in English, German, Spanish, and Turkish. SUBSCRIPTIONS Free to start. Optional subscriptions unlock higher usage and advanced features, billed through your App Store account. Manage or cancel anytime in your account settings. Synaplan is flexible and open: the platform is brandable and can be self-hosted, so the same app works for Synaplan.com and for your own AI platform.

Turn on Nerd Mode in Settings to reveal host tools like files, plugins and logs. OPTIONAL DEVICE TOOLS With your permission, agents can add to your Calendar and Reminders and see where you are. Each is off until you turn it on under Permissions. HOW BIGHELP CONNECTS bighelp connects directly to a Hermes host you run, such as your own Mac, over your home network, Tailscale or HTTPS. Sign in with that host's own login. No separate bighelp account is needed. The free bighelp plugin for Hermes adds notifications, live voice, cards and the Feed. Your Hermes host remains the agent engine. AI, voice, storage and infrastructure providers configured on that host may process data under their own terms and may require separate accounts or subscriptions.
