Aitopus: Private AI Assistant
Offline chat, docs, web search
Free
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.
