More than just a chatbot. Razvigor lets you branch, annotate, and navigate AI conversations like a mind-map. Start free with our built-in AI proxy, upgrade to Pro for Google, OpenAI, and Anthropic models with no API key, or bring your own key for OpenAI, Claude, Gemini, or OpenRouter.
Free unlocks Google's Gemini via our built-in proxy, no API key needed. Pro unlocks OpenAI and Anthropic through that same proxy too - still no key required. Or connect your own OpenAI, Anthropic, Google Gemini, or OpenRouter key for full control. Switch providers and models from the chat header at any time.
Every thread appears as a collapsible tree in the sidebar, with connecting lines showing parent-child relationships. See exactly how your conversations relate at a glance.
Select text in any message. A popup offers Create Branch, Create Note, or Highlight. Branching spawns a new thread pre-seeded with that text, original preserved.
Highlight selected text in 7 preset colors or create your own custom colors. Highlights appear as colored overlays directly on the message, with a hover preview on desktop.
Attach written notes to any selected text, color-coded alongside highlights. A dedicated sidebar lets you search, filter by type or color, and click to jump to any annotation.
Export all conversations (threads, messages, annotations, and hierarchy) to a JSON backup file. Restore it anytime with Import. Cloud sync via Firebase keeps everything in step across devices.
Group your threads into projects, and nest folders inside them to keep large workspaces tidy. Move any thread or branch to a different project or folder at any time.
Open any project as a zoomable, pannable graph of every thread, folder, and branch. Expand or collapse nodes, click any node to jump straight into that thread, or go full screen for the bird's-eye view.
Select any text and choose Explain for a short, streamed AI explanation right in a floating popup - no new thread, no losing your place in the conversation.
A workflow built around non-linear thinking. Explore any direction without losing your thread.
Start chatting immediately with our built-in AI proxy - free with Google Gemini, no API key needed. Upgrade to Pro to unlock OpenAI and Anthropic through that same proxy too, still with no key required. Or connect your own OpenAI, Anthropic, Google Gemini, or OpenRouter key for full control.
Select text in any message to highlight it in one of 7 preset colors or a custom color, or attach a written note. A dedicated sidebar shows all annotations with search and color filtering. Click any entry to jump to its message.
Select text in any message and choose "Create Branch". A new thread opens pre-seeded with either the selected text or a summary of the whole conversation, your choice. The original thread is preserved. Navigate the full tree from the collapsible sidebar.
Group related threads into projects, and nest folders inside them to keep large workspaces tidy. Use "Move to…" on any thread to relocate it - moving a branch detaches it from its parent conversation, so it stands on its own.
Open any project as a graph: threads, folders, and branches laid out automatically, left to right. Expand or collapse nodes to focus on what matters, zoom and pan freely, or pop the whole graph into full screen.
Select any text and choose Explain for a short explanation that streams in right inside the popup. It's a quick detour, not a new thread - your conversation stays exactly as it was.
