Most people do not want to become AI infrastructure experts. They want a useful answer, a place to think, and confidence that a private question is not automatically sent to a remote service.
That is the product boundary behind Pebble Mind: a local-first AI workspace for iPhone and iPad. The local workflow is designed to work without an account or API key, using supported Apple and GGUF models on the device. The app shows model details and device-readiness information before download so the experience starts with clear expectations.
Once a model is ready, Pebble Mind provides a focused chat with streaming responses, Markdown, conversation history, search, storage management, and supported attachments. The goal is not to hide complexity behind a slogan; it is to make the useful path obvious for people who want private AI without giving up a polished mobile workflow.
The privacy boundary is explicit:
- Local chats stay in the local workflow and do not require an account.
- Web search is a separate, optional action with visible sources when enabled.
- Model downloads and storage are visible in the app.
- Pro features add custom model importing, expanded model management, advanced controls, configurable search domains, data transfer tools, and context compaction.
This makes the app useful for two groups at once. Everyday users get a straightforward private assistant for drafting, summarizing, planning, and thinking. Developers and local-LLM users get a mobile place to work with supported local models and understand what is running before they start.
