I recommend creating 3 worldlines to validate in parallel:

Beta Β· SMB Gamma Β· Mid-market Delta Β· Enterprise

One Question, Two Paths

See how a single thought diverges into multiple worldlines, each preserving full context.

Should we implement this with WebSocket or SSE?
It depends on your specific needs. Let's analyze from two angles...

Designed for Deep Thinking

Not just chat β€” a complete system for reasoning and exploration. Capture every branch of inspiration, as natural as your own thought process.

Visual Thought Mapping

Stop scrolling endlessly. Visualize your entire conversation logic as an interactive tree. Spot patterns, find dead ends, and navigate complex arguments with zero mental friction.

Parallel Worldlines

Create "What If" scenarios instantly. Branch from any point to explore alternative outcomes without losing your original thought process.

Local-First Control

Data stays in local IndexedDB by default, with notepad-level responsiveness. Need cross-device collaboration? Enable account and cloud sync when you need it.

Multi-Model Orchestration

Don't settle for one opinion. Seamlessly switch between Gemini, Claude, DeepSeek, and more within the same conversation tree to compare insights.

Beyond Traditional Chat

Not just a better chat tool β€” an entirely new operating system for your thoughts.

Built for Complex Reasoning

Whether you're a researcher, writer, developer, or decision-maker, branching conversations unlock new ways to think.

Deep Dive Research

Start from a hypothesis. Branch into multiple rabbit holes. Hit a dead end? Just jump back to the main trunk and try a new angle.

Branch A: Behavioral Economics
Branch B: Classical Economics

Story Forking

Writer's block? Branch out three different plot twists from the same scene. Keep every spark of inspiration, then pick the winner.

Branch A: Hero saves the city
Branch B: Hero becomes villain

Strategy Sandbox

Simulate the outcomes of Strategy A vs Strategy B in parallel worlds. Roleplay with different stakeholders before making the final call.

Branch A: Focus on Enterprise
Branch B: Focus on PLG

Fearless Refactoring

Don't settle for the first solution. Try Implementation A in one branch, and Implementation B in another. Compare code quality side-by-side without polluting your context.

Branch A: React Implementation
Branch B: Vue Implementation

Socratic Learning

Didn't get it? Branch off and ask "Can you explain like I'm 5?". Want more depth? Branch again and ask "Show me the math".

Branch A: Explain with Math
Branch B: Explain with Analogy

Devil's Advocate

Feeling too confident? Have AI roast your idea in a separate branch. Stress-test your arguments against the harshest critic without derailing the main chat.

Branch A: Pro-Argument
Branch B: Counter-Argument

Built for Transparency

Verifiable architecture choices: local-first defaults, bring your own keys, exportable data, and a public roadmap.

Local-first is default, not a toggle

From first use, Zavune runs in local-first mode without forcing an account. You only enable sync when cross-device access is actually needed.

BYOK with direct provider calls

Bring your own API key and call model providers directly from your browser. You keep control over provider choice, model mix, and spend strategy.

Exportable, backup-ready, migration-safe

Conversations can be exported as JSON or images, reducing lock-in risk. Your reasoning structure stays portable across tools and time.

Roadmap by capability phase

We prioritize stable, verifiable capabilities first, then layer advanced collaboration features.

Your Data, Your Control

Zavune is local-first by default. You can use it without signing in, or optionally enable account and cloud sync capabilities when needed. Control stays in your hands.

Local-First by Default

By default, your conversation history, settings, and API keys stay in your browser. No sign-up required to start.

Direct Provider API

Your browser calls providers like Gemini, Claude, and DeepSeek directly. Bring your own key, choose your own models, and control your own costs.

Optional Cloud Sync

Need cross-device collaboration and backup? Enable account and cloud sync when you want. Prefer local only? Keep it fully local.

Frequently Asked Questions

Everything you need to know about Zavune.

What is a "worldline"?

A worldline is Zavune's core concept. When you create a branch from any conversation node, a new worldline is born. Each worldline is an independent conversation path that you can switch between and compare. Like parallel universes, each worldline has its own color and divergence value.

Which AI models are supported?

Supports Gemini, Claude, DeepSeek, GLM, and more. You can use different models on different worldlines to compare how different AIs answer the same question.

Where is my data stored?

By default, data is stored locally in your browser (IndexedDB). If you optionally enable account and cloud sync, data is synced within your authorized workspace for cross-device access.

Is it free?

Yes, you can start for free. We provide a core free experience and will progressively offer advanced feature tiers. Model usage costs are still billed by your provider (BYOK).

Do I need to create an account?

Not necessarily. You can use Zavune locally without signing in. If you need cross-device sync, cloud backup, or collaboration, you can optionally enable account features.

What is "divergence"?

Divergence is a numerical measure of how different a worldline is from the main line (Alpha). The higher the divergence, the more the worldline has deviated from the original conversation path. It helps you quickly gauge the distance between different lines of thinking.

Can I export my conversations?

Yes. You can export as JSON files (containing the full conversation tree structure) or as images. Back up your data or share with others anytime.

Will I lose data if I switch browsers or clear cache?

If you only use local mode, clearing browser data can remove your conversations. We recommend regular exports, or enabling optional account and cloud sync capabilities.
