Frequently Asked Questions
Detailed answers to common questions about Lite Mind
Which AI model should I choose?
For most users, we recommend SmolLM2-1.7B for the best balance of speed and capability. If you need more advanced reasoning, try Llama-3.2-1B. Qwen is great for multilingual tasks, and Phi models offer good performance on newer devices.
How much storage space do I need?
AI models range from 1-3GB each. We recommend having at least 5GB of free storage before downloading. The app itself is small (~50MB), but models require significant space.
Can I use multiple AI models?
Yes! You can download multiple models and switch between them. However, only one model can be active at a time, and each model takes up storage space.
What file formats are supported for document analysis?
Lite Mind supports PDF files, Word documents (DOCX), and image files (JPG, PNG, HEIC). OCR works on images and scanned PDFs to extract text.
Is there a file size limit for documents?
Yes, individual files are limited to 50MB for performance reasons. Most documents are much smaller than this limit.
How do I delete my conversation history?
Go to Settings > Privacy > Clear Conversations. You can delete individual conversations or clear all history. Remember, this data only exists on your device.
Can I backup my conversations?
You can export conversations as text files for backup purposes. Go to Settings > Export Data. Imported conversations are not automatically synced.
What Android version do I need?
Lite Mind requires Android 8.0 (API level 26) or higher. We recommend at least 4GB of RAM for optimal performance, especially with larger models.
Why is my first response slow?
The first response after opening the app can take 10-30 seconds as the AI model loads into memory. Subsequent responses are much faster.
Can I use Lite Mind for commercial/business purposes?
Yes! Lite Mind is perfect for business use since all data stays on your device. Many professionals in healthcare, legal, and finance use it for sensitive work.
