One brain.
Every product.
Workshop, Venue, and Academy look like three products. Underneath, they're one platform — four invisible pillars that store your world, accelerate the heavy work, remember who you are, and care about what matters to you.
You don't have to think about any of this. But it's why every Soulcraft product feels like part of the same mind, not a stack of separate tools.
Brainy
The open-source knowledge operating system
Every Soulcraft product runs on Brainy — a graph + vector database that stores everything from a customer record to a chat turn to a whole knowledge graph. MIT licensed and free forever; runs on its own up to millions of entities. Drop in Cortex when you need to scale to billions.
- Graph + vector + metadata in one store
- Local-first; runs anywhere with an SSD
- Zero-config: just store and search
- MIT licensed — yours to keep
Cortex
10 billion entities on a laptop
Cortex is the native Rust accelerator that scales Brainy from millions of entities to billions — on a laptop, a $60/month Hetzner box, or any commodity hardware with an NVMe SSD. Same Brainy code, same files, same API: install Cortex and Brainy is faster; remove Cortex and Brainy still works. No data migration. No vendor lock-in.
- 10 billion entities on commodity hardware
- DiskANN algorithm (Microsoft Research, 2019), reimplemented in 100% Rust
- Same Brainy code, same files, same API
- Self-hostable: laptop, Hetzner, or any cloud VM
Memory
Context that never forgets
Memory works like a brain instead of a database. It remembers, consolidates while you sleep, abstracts patterns, and anticipates — so every conversation picks up where the last one left off, and your AI gets smarter about you over time.
- Hippocampal-style retrieval per turn
- Overnight consolidation builds dossiers
- Weekly insight & monthly distillation
- Works across every Soulcraft product
Heart
Empathy as a service
Heart gives every Soulcraft AI an emotional dimension — recognising tone, weighing what matters to you, and softening its response when the moment calls for it. The same context Memory holds, judged through a human lens.
- Tone-aware response shaping
- Empathic memory weighting
- Cross-product emotional continuity
- Pluggable into any agent or workflow
How they fit together
The pillars aren't separate products you stitch together — they're one stack designed as a unit. Brainy holds the data, Cortex accelerates it, Memory shapes it into context, Heart filters it through empathy.
Brainy is the substrate — graph, vectors, metadata in one place.
Cortex turns the substrate into a high-performance brain at scale.
Memory builds dossiers and consolidates while you sleep.
Heart weighs the response by what matters to you in the moment.
Workshop, Venue, and Academy sit on top — three different surfaces, one shared mind underneath.
Build something that matters.
Pick the product that fits today — Workshop to build, Venue to run, Academy to grow. The platform comes with all of them.
