World's Best Memory
Backboard captures what your AI needs to remember and organizes it for reliable use across any conversation or stack. It stores context, interactions and long-term knowledge, then retrieves the right pieces at the right time. Memory becomes architecture, not a feature.

Configurable AI Stack
Build exactly the system you want. Combine any model, embedding, vector database and memory setting into a custom stack optimized for your use case. Swap components instantly, tune performance and cost on the fly, and experiment across more than a million possible configurations. It gives developers full control without the overhead of managing complex infrastructure.
