Start by exploring the dashboard. Try asking Lexi a simple legal question to see how it works. Upload a test document to experience document analysis. Set up your profile and notification preferences in Settings.

Lexi is your AI legal assistant. Ask questions in natural language, upload documents for analysis, research case law across 50+ official sources, and get citations for every answer. Lexi remembers context within your conversation for follow-up questions.

The sidebar shows your main sections: Chat for conversations with Lexi, Documents for file management, Projects for organizing work, and Settings for account preferences. Use the search bar at the top to quickly find anything.

Each plan includes a monthly quota of AI queries and document uploads. Check your current usage in Settings > Subscription. Limits reset on your billing date. Upgrade your plan anytime for higher limits.

Yes! LexAI works as a Progressive Web App (PWA). In Chrome, click the install icon in the address bar. On Safari, use "Add to Dock". This gives you a dedicated app window and faster access.

Be specific about the legal area, jurisdiction, and what you need. Instead of "tell me about contracts", try "What are the notice requirements for terminating an employment contract under Czech Labour Code Section 48?" Include relevant facts and context.

LexAI connects to 50+ official sources: Czech Court database, Constitutional Court decisions, Sbírka zákonů, EUR-Lex for EU regulations, Ministry of Justice repositories, and established legal commentaries. Select specific sources or let Lexi choose automatically.

Upload documents to a project, then enable "Project Context" in chat. Lexi will reference your uploaded files when answering. You can also drag a document directly into the chat window for immediate analysis.

Incognito mode prevents your conversation from being saved to chat history. Use it for sensitive matters or when you don't want a record. Enable it from the chat options menu before starting your conversation.

Click the export button in any conversation to download as PDF or Word document. You can also copy individual responses, or use the "Save to Project" feature to attach conversations to specific matters.

LexAI is a research assistant, not a lawyer. Always verify critical information, especially for recent legal changes. The AI may occasionally misinterpret complex questions. Use the source citations to verify all answers before relying on them for client work.

LexAI supports PDF, DOCX, DOC, and TXT files. PDF works best for most legal documents. We recommend native PDFs over scanned images - if you must use scans, ensure they've been OCR processed first.

Go to Documents section and click "Upload" or drag files directly. You can also drop files into a chat conversation for immediate analysis. Files are encrypted during upload and storage.

Lexi can summarize documents, identify key clauses and risks, extract parties and dates, compare documents against each other, and answer questions about document content. Ask specific questions for best results.

Create a project from the Projects section. Add documents by uploading directly to the project or moving existing files. Projects help keep related documents together and enable project-wide context in chat conversations.

Maximum file size is 25MB per document. For larger files, consider splitting into parts or compressing PDFs. Your plan determines total storage capacity - check Settings > Subscription for your limits.

Check file size (max 25MB) and format (PDF, DOCX, DOC, TXT). Try a different browser like Chrome or Firefox. Ensure stable internet connection. If the file is password-protected, remove protection first. For corrupted files, try re-saving from the original application.
