Built for non-linear thinking
More than a chatbot. Branch, annotate, and navigate AI conversations like a mind-map.
Branch from any text
Select any passage and turn it into its own thread. The original conversation stays untouched.
Highlights & notes
Mark what matters in color, attach notes, and jump back to any of them from one searchable panel.
See the whole map
Every branch lives in a thread tree and an interactive graph, organized into projects and folders.
Any model, no API key
Gemini for free, OpenAI and Anthropic on Pro, or bring your own key. Switch models mid-conversation.
Quick Explain
Get a short explanation of any selected text in place, without starting a new thread.
Synced and portable
Your threads follow you between desktop and Android, and export to a JSON backup anytime.
How Razvigor works
A workflow built around non-linear thinking. Explore any direction without losing your thread.
Start chatting right away, switch models anytime
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.
- ✓Free tier included, no API key required to get started
- ✓Pro adds OpenAI and Anthropic - still no API key needed
- ✓Bring your own key for OpenAI, Claude, Gemini, or OpenRouter
- ✓Switch models mid-conversation
Highlight and annotate any response
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.
- ✓7 preset colors plus custom color support
- ✓Written notes color-coded alongside highlights
- ✓Search all annotations across the thread
Branch into any direction without losing your place
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.
- ✓Branch from any message in any conversation
- ✓Unlimited depth, branches can branch further
- ✓Sidebar tree shows all threads with parent-child lines
Organize with projects and folders
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.
- ✓Projects hold folders and root conversations
- ✓Folders can nest inside other folders
- ✓Move any thread or branch anytime with "Move to…"
Visualize every branch as an interactive graph
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.
- ✓One graph per project, generated automatically
- ✓Expand or collapse any node to show or hide its branches
- ✓Click a node to jump straight into that thread
Get instant answers without leaving the message
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.
- ✓Explains any selection in 2-3 sentences
- ✓Streams in live, right where you're reading
- ✓Doesn't create a branch or alter your history
Your threads, in your pocket
Everything you do on the desktop works on your phone too. Pick up a branch on the go, or find that note you left yourself yesterday.
- ✓Select text to branch, highlight, add a note or get a quick explanation
- ✓Notes panel with search to jump back to anything you marked
- ✓Same account, so your threads and branches are there on every device
