LLM Vault is your personal vault for organizing conversations, answers and notes generated by AI models (ChatGPT, Claude, Copilot, Gemini, Grok and others) — all in Markdown, stored locally on your computer, with no account and no cloud. OBSIDIAN-STYLE ORGANIZATION Create folders and subfolders to separate your projects, topics or clients. Each entry keeps its title, tags, the AI model used, and its creation and update dates. Already have .md files? Import them straight into the vault. AI MODEL CATALOG ChatGPT, Claude, Copilot, Gemini and Grok come pre-registered. Add any other model on the spot, right from the editor, and rename it whenever you like — the new name is automatically applied to every entry that uses that model. EDITOR WITH LIVE PREVIEW Write or paste Markdown and see the rendered formatting instantly, side by side, with scrolling synchronized between both panes. Links open in your default browser, and right-clicking lets you copy the text or a link's address. The editor warns you about unsaved changes, so you never lose anything when closing. VISUAL THEMES Choose from eight themes — System, Light, Dark, or accent-color themes (Blue, Green, Beige, Purple) — or build your own custom theme: pick the colors, a light or dark base, and save your favorite combinations by name to reapply later. PORTUGUÊS, ENGLISH AND ESPAÑOL Full interface in three languages. LLM Vault detects your Windows language the first time it opens, and you can switch at any time from the Language menu. EXPORT AND BACKUP Export any entry to PDF. Set up automatic backups (daily, weekly or monthly) or back up manually whenever you want, with simple restore from the Settings screen. Before every restore or update, the app automatically keeps a safety copy of your data — if anything goes wrong along the way, everything returns to its previous state. PRIVACY FIRST All your data lives in a local database (SQLite) on your computer. No data collection, no syncing with external services, no account to create. Ideal for anyone who uses AI every day and wants to keep an organized history of useful prompts and answers, without relying on scattered browser tabs or lost notes.
