Yes, offline AI works without internet — but not all AI tools do. EVA is a fully offline AI assistant that runs directly from a USB drive on Windows 10/11 PCs. Once set up, its core chat and document features operate entirely on your local machine, with no connection to any cloud server required. You do not need Wi-Fi, a mobile hotspot, or any internet access for EVA to answer questions, analyze documents, or hold a conversation.
Why most AI tools require an internet connection
Tools like ChatGPT, Gemini, and Copilot work by sending your prompts to remote servers, processing them using massive cloud-based language models, and returning a response. That architecture means every query you type leaves your device. It also means those tools stop working the moment your connection drops.
EVA is built differently. The AI model and your document knowledge base both live on the USB drive. Your queries never travel beyond your own computer.
How EVA works without the internet
EVA runs a local language model directly on your Windows PC's CPU and RAM. When you ask it a question:
- Your prompt stays on your device
- The local model processes it using your PC's processing power
- The response is generated locally and displayed to you
- No data is sent to EVA's servers or any third-party cloud
For document-based queries, EVA can index files you add to the drive locally. When you ask a question about your documents, it retrieves relevant content from those local files and incorporates it into its response — all on-device.
What EVA can do offline
- Answer general knowledge questions based on the model's training
- Analyze, summarize, and discuss documents you've added to its local knowledge base
- Draft text, emails, memos, and summaries
- Retain selected conversation context within a session on the drive
- Work on sensitive documents without cloud exposure
What requires an internet connection
Honesty matters here. Some tasks still require internet access, regardless of what AI tool you use:
- Real-time information: EVA cannot browse the web or access current news, live data, or recent events. If you need up-to-date information, you will need an internet-connected service for that task.
- Model updates: Downloading model updates requires a connection, though day-to-day use does not.
Who benefits most from offline AI
EVA is particularly well-suited for:
- Legal and financial professionals handling confidential client documents that cannot go to the cloud
- Field workers and travelers operating in areas with unreliable or no internet access
- Privacy-conscious individuals who want their document analysis and queries to stay entirely local
- Anyone on Windows 10/11 who wants predictable, subscription-free AI that works regardless of network availability

System requirements for running EVA offline
EVA is designed for Windows 10 and Windows 11 PCs. Performance depends on your hardware. In general, a modern PC with at least 8 GB RAM will run EVA, with better performance on systems with more RAM and a faster CPU. See the EVA Compatibility & Requirements page for full specifications.
Frequently asked questions
Can I use EVA on a plane or in a location with no Wi-Fi?
Yes. Once the drive is set up, EVA's core chat and document features work without any network connection.
Does EVA send my documents to any server?
EVA's local document workflow is designed to process your files on-device without transmitting them to EVA-operated or third-party cloud servers. See the EVA Privacy Architecture page for full scope and any exceptions.
How is EVA different from running a model like Ollama locally?
EVA is a ready-to-use product on a USB drive — no technical setup, no command line, no admin permissions required. It is designed for professionals who want local AI without needing to configure a development environment.
Is the AI model trained on my documents?
No. EVA indexes your documents locally for retrieval purposes. It does not use your files to retrain the AI model.
EVA is sold by Intelligence by Macci. Pricing and specifications are subject to change. Performance varies by PC hardware, document size, and workload. EVA does not provide legal, medical, or financial advice.
