Software studio · AI infrastructure

Practical AI infrastructure, plus a portfolio of careful software projects.

9thBit LLC is a small software company. Our flagship work in 2026 is AI infrastructure: UrBrain, a hosted memory layer for agent systems, and StructuredMerge, the deterministic ingest engine that powers it. Alongside those products we run a portfolio of publishing, civic research, and consulting projects — all built from the same habit of making the work clearer than it was before.

2026 focus

Memory that knows what changed.

UrBrain · ur-brain.tech

Hosted memory for AI agents.

UrBrain is a hosted memory layer for agent systems and RAG-backed products. It stores source documents, document versions, memories, embeddings, and retrieval policy under account, organization, and workspace boundaries — so agents retrieve current truth, scoped to the people and teams allowed to see it.

StructuredMerge · structuredmerge.org

Deterministic document ingest.

StructuredMerge compares prior and current document versions and emits stable chunk IDs, content hashes, upserts, and tombstones. UrBrain uses it internally so document updates produce reviewable deltas instead of reprocessing every memory from scratch. The same engine powers any pipeline that needs predictable, replayable diff and merge artifacts.

Publishing and archives

Sites for public letters, durable documents, and material that should stay easy to find.

Civic and research tools

Projects that make public information easier to read, compare, and act on.

Web consulting

Architecture, implementation, and cleanup work for teams that need experienced help.

Approach

Plain software, maintained well.

  1. Start with the smallest version that makes the idea understandable
  2. Keep the structure simple enough to change later
  3. Use public pages to explain what exists now, not just what might exist someday
  4. Spend the most attention where people will use it

Portfolio

Flagship products, plus active sites and concepts.
