Proton Lumo Exporter — Backup Your Private Lumo Chats
Because Proton Lumo uses end-to-end encryption, our parser extracts the rendered DOM locally on your machine with zero privacy compromise.
Why Export Proton Lumo Conversations
Proton Lumo offers privacy-first AI assistance with end-to-end encrypted storage. Because API payloads are encrypted, third-party cloud archivers cannot read your data.
AI Chat Exporter operates strictly inside your authenticated browser session on the client side, reading the decrypted DOM after you view it. Your private conversations never leave your device.
Lumo-Specific Extraction
Tailored for lumo.proton.me DOM structure and code syntax blocks:
Local Decrypted DOM Extraction
Parses decrypted conversation items cleanly without needing your Proton private keys.
Syntax Highlighter Preprocessing
Converts Lumo custom syntax highlighter blocks into standard Markdown code blocks.
Continuation to Other LLMs
Transfer your Lumo prompts into Claude, Gemini, or ChatGPT in one click.
Clean Markdown Export
Outputs clean, portable Markdown ready for Obsidian, Logseq, or local text editors.
Seven Export Formats Supported
Every Proton Lumo conversation can be exported into whichever format best fits your workflow:
| Format | Best For | Features |

| PDF (.pdf) | Printing, archiving, sharing | Formatted headers, rendered math, page breaks, syntax highlighting |
