Big-AGI alternative: give your conversations room to branch.
Big-AGI is relevant when comparing answers from several models is the central activity. Consider CocoCroco when your project branches into different questions and you want to keep those lines of inquiry organized.

Is switching worth it?
Big-AGI’s Beam is designed around parallel model responses and their synthesis. CocoCroco’s pitch is a connected board of conversations. Comparing models and comparing lines of thought are related tasks, but they are not interchangeable.
Consider Big-AGI if…
Browser-based direct provider connections and parallel multi-model comparisons are your priority.
You want to mix local runtimes with cloud providers in the same chat.
Try CocoCroco if…
Your work develops into several related conversations.
You want to branch from a message with its earlier context.
You want chats, notes, and code together on the canvas of a board.
Start with one conversation. Explore two directions.
Branch a research answer into a counterexample, a practical application, and a follow-up experiment. Keep the three directions visible beside the original premise.
In CocoCroco, a branch starts from a message or selected passage with the earlier conversation as context. The original thread stays intact, and the new chat stays visibly linked to its origin. Your board can hold the supporting notes and code as the project grows.
The useful test is simple: can you return later and understand why the work split? A spatial view should make the project easier to navigate, not just look different.
Before leaving Big-AGI
Decide whether you mostly send the same request to multiple models or develop different follow-up questions over time.
Try one small project in CocoCroco with your intended provider.
Branch at a useful message and continue both conversations.
Keep your original chats. Verify any export format before assuming it imports elsewhere.
CocoCroco supports its own export/import workflow. This guide does not promise direct migration from Big-AGI.
Questions before you choose
What does the free app include?
The free browser app includes unlimited chats, 4 boards, 2 personas, and 2 prompts. You bring your own API key and pay your provider for AI usage separately.
Do I need to install the desktop app?
No. You can start in the browser without an account or credit card. Pro costs $97 once and adds browser upgrades, unlimited libraries, and Windows/Linux desktop access.
Where are my conversations stored?
Saved work stays locally on your device. When you send a message, the prompt and relevant context go to your selected AI provider. There is no automatic cloud sync; export/import moves boards between devices.
What if your work needs room to branch?
Try CocoCroco alongside Big-AGI with one real task. Bring your provider keys, branch where the discussion gets interesting, and keep the related chats, notes, and code visible together.
