OneChats AI

Multi-agent research that returns a cited report. Local models run on-device via MLX. Every major LLM in one app — your iPhone dispatches, your Mac does the work.

OneChats — Every top AI model, in one smarter workspace

Not every AI client manages to be both powerful and elegant. OneChats aims for both. We bring the world's leading large language models together in one clean, fluid space — clearing away the clutter so you can focus on thinking and creating.

[Every Top Model, One Tap Away] Bring together the world's leading large language models, fully compatible with the universal API standard. No more jumping between apps — call up the right "brain" for any task, instantly.

[Your Private Knowledge Base] Import PDFs, documents, and notes, and OneChats uses AI to compile them into structured articles. Turn on Knowledge Base, and the AI answers from your own private material — with cited sources. Create multiple knowledge bases and sync them across your devices.

[140 Curated Agents, Free to Use] 140 professional agents built in — covering reasoning & decisions, product growth, writing, learning, legal & finance, personal productivity, and more. Add any of them for free with a single tap, with more in every update. Create your own agents and system prompts, or use the built-in prompt template library, to assemble your personal team of experts.

[Save the Best, Never Lose a Spark] Save standout exchanges with one tap — the AI's answer, its reasoning, and any attachments all included. Organize them into custom groups, sync across devices, and revisit anytime. Your favorites stay even if the original chat is deleted.

[Built for Coders and Researchers] Flawless rendering of every major programming language, with native LaTeX typesetting that makes even complex math crystal clear. Markdown, tables, and syntax highlighting all included.

[iCloud Sync, Seamless Across Devices] Chats, agents, prompts, favorites, and knowledge bases sync automatically through your own private iCloud database, keeping iPhone and Mac perfectly in step.

[Deep Research, Run in the Background by Your Mac] Kick off a deep-research task from your iPhone and let your Mac orchestrate a team of agents in the background — breaking the problem down, searching in parallel, cross-checking findings, and producing a fully cited research report or white paper. Results sync back to your iPhone via iCloud, ready to export as DOCX, PDF, or Markdown. Start it on your commute; come home to a finished draft. (Requires a Mac running OneChats with Remote Mode enabled.)

[Private Models Over Your Local Network] Run private models locally on your Mac and connect securely from your iPhone over your local network (end-to-end TLS encryption + certificate validation + same-iCloud-account authentication) — your data never has to leave your home network. Also compatible with local inference services that follow the universal API standard. (Requires a Mac running OneChats.)

[Privacy on Your Terms] OneChats has no servers of its own and collects none of your data. Your conversations flow only between your device, your own iCloud, and the AI service you choose — plus any search engine or web page an agent visits when you ask it to research online. Your API keys are stored only in your device's keychain, never uploaded to the cloud.
