If you have ever watched an AI confidently answer a question using the wrong context — or forget everything you told it five minutes ago — you already understand the problem Leader Brain solves. Most AI tools are stateless. You ask, they answer, they forget. The next conversation starts from zero. For casual chat, that is fine. For real work — managing projects, running a business, building software — it is a dealbreaker. Leader Brain is High Limit Designs' answer to that problem. It is a file-native AI knowledge engine that reads, understands, and reasons over your documents, code, and data. And it remembers everything across sessions.
How Leader Brain Works
The architecture is straightforward:
1. Upload your files — PDFs, markdown, code, spreadsheets, presentations, transcripts. Leader Brain processes and indexes all of it.
2. Semantic search, not keyword search — When you ask a question, Leader Brain retrieves information based on meaning, not string matching. A question about "scaling issues" will find a document about "performance bottlenecks under load" even if those exact words never appear.
3. Persistent knowledge base — Your brain grows over time. Every file you add, every question you ask, every insight the system generates becomes part of a knowledge graph that compounds in value.
4. API access — Your brain is not locked inside a chat window. The Brain API lets any application, agent, or workflow query your knowledge programmatically. This is where Leader Brain becomes infrastructure, not just a tool.
The Brain API
Leader Brain exposes a REST API that makes your knowledge accessible to anything that can make an HTTP request. Every brain gets a unique ID. Every query returns structured results with source citations. The API supports:
- Text-to-brain queries — Ask natural language questions, get answers grounded in your uploaded content
- Public and private brains — Share knowledge via URL, or lock it down. Starter plans get public sharing. Pro and Enterprise unlock private brains.
- Monthly API quota — Every plan includes a monthly call limit. Starter gives you 1,000 Brain API calls per month. Pro bumps that to 10,000. Enterprise goes to 100,000.
- JSON export — Download your brain configuration as a portable JSON file. Your knowledge is never trapped inside our platform.
This matters because it makes Leader Brain composable. An AI agent can query your brain. A CI pipeline can check your brain for past architectural decisions. A customer support tool can search your brain for relevant documentation. The brain becomes a node in your infrastructure, not a standalone app.
What a Brain Actually Is
A brain is not a single file or a database row. It is a structured knowledge system made of:
- Knowledge — Product docs, architecture notes, strategies, reference material
- Experience — Runbooks, what worked, what failed, operational history
- Observations — Real-time telemetry, events, metrics, alerts
Think of it like this: knowledge is what you know, experience is what you have been through, and observations are what is happening right now. Leader Brain stores and retrieves across all three.
At the file level, a brain is a directory of markdown files — identity, knowledge, experience, dreams. That is intentional. Markdown is human-readable, version-controllable, and portable. If High Limit Designs disappeared tomorrow, your brain files would still work. You could drop them into any LLM context window and the knowledge would transfer.
Who Leader Brain Is For
Developers — Index your codebase. Ask questions about architecture decisions, bug patterns, and implementation details. Stop digging through Confluence and Slack threads. Your brain already knows. Founders and operators — Upload business plans, meeting notes, financials, and competitor research. Ask your brain for strategic context instead of re-reading everything yourself. AI agent builders — This is the key use case. If you are building autonomous agents, they need persistent memory. Leader Brain gives them a knowledge layer they can query in real time. The brain becomes the agent's long-term memory. The API becomes the agent's sensory input. Teams — Shared brains mean shared context. Onboard new members by giving them brain access. Reduce the "let me find that doc" cycle. Let the brain answer the questions that keep getting asked in Slack.The Leader Brain Creator
The /brain page in High Limit Designs is where you build and configure brains. It is not just a form — it is a no-code AI agent configuration generator. You define:
- What the brain knows (knowledge uploads)
- How the brain reasons (persona and behavior settings)
- What the brain can do (API permissions, tool access)
- How the brain shares (public URL or private access)
The output is a brain.json — a portable configuration file that works with any Hermes Agent instance. This is by design. We believe you should own your AI's brain. Vendor lock-in is the enemy of long-term AI adoption. Your brain files should outlast any platform.
Templates are available for common starting points — SaaS startup brain, freelancer client brain, DevOps agent brain. More are coming.
Plan Tiers and What You Get
Leader Brain is available on every High Limit Designs plan. The difference is scale and features:
| Feature | Starter (Free) | Pro ($29/mo) | Enterprise ($99/mo) |
|---|---|---|---|
| Brain API calls/mo | 1,000 | 10,000 | 100,000 |
| Max brains | 3 | 10 | Unlimited |
| Public sharing | Yes | Yes | Yes |
| Private brains | No | Yes | Yes |
| Inference API | No | Yes | Yes |
| Vector DB access | No | No | Yes |
| Brain JSON export | Yes | Yes | Yes |
The Starter plan is designed to let you build and experiment without paying anything. The Pro plan unlocks private brains and inference access — the point where your brain becomes production infrastructure. Enterprise is for teams running agents and applications at scale.
Why File-Native Matters
Leader Brain is file-native by design. Your knowledge lives in markdown files — not in a proprietary database format, not in a vector embedding you cannot read, not in a SaaS lockbox. This matters for three reasons:
1. Portability — Copy your brain directory anywhere. It works. No export, no migration, no API keys required to read your own knowledge.
2. Version control — Put your brain in Git. Track changes. Roll back mistakes. Collaborate with pull requests. Your knowledge has a history.
3. AI-agnostic — The files work with any LLM. Claude, GPT, Gemini, open-source models — they all read markdown. Your brain is not tied to a model provider.
The vector database and semantic search are how Leader Brain finds answers. The markdown files are what it finds. Those are two different layers, and the file layer is the one you own.
What Comes Next
Leader Brain is live and shipping. Here is what is on the roadmap:
- Template marketplace — Community-contributed brain templates for specific industries and use cases
- Direct agent deployment — Configure a brain, deploy it as a live Hermes Agent in one click
- Multi-brain linking — Connect brains together so an agent can query multiple knowledge sources
- Brain versioning — Track how your brain evolves over time, branch and merge knowledge
- Fine-tuning hooks — Use your brain's knowledge to fine-tune models for your specific domain
The long-term vision is simple: every AI agent should have a brain. And every brain should belong to the person who built it.
