Local-first AI,
that actually remembers you

We build the open-core AI runtime, memory, and personality layer that runs on your machine, and scales from a private desktop assistant to a company-wide knowledge model that respects your data.

AI Platform

One open-core stack.
Personal assistant to company brain.

Engram remembers. Persona speaks. Cortex knows. Pyre brings them to life. przm measures whether any of it actually works. Same runtime from a single user's laptop to a company's on-prem deployment. Local models or any cloud provider, your data, your hardware.

Pyre

The control plane for local intelligence.

Runs Qwen3-14B on a 16 GB consumer GPU with up to 200 K effective context and 8-hour agent sessions with zero API spend. A multi-agent runtime that adapts to your hardware, switches between local and any cloud provider per conversation, and remembers everything via Engram. Pro keeps your agents, memory, and personality continuous across every device. Enterprise adds on-prem deployment, SSO, audit, and managed company-knowledge ingestion via Cortex. Same runtime, same memory, same personality, all the way up.

przmOpen Source + Cert

Vendor-neutral leaderboard for AI failure modes. Multi-agent convergence, sycophancy, memory recall. Deterministic scoring, Ed25519-signed receipts, no LLM in the grading loop. Open source plus per-release certification for framework vendors.

Engram

Open Source + Cloud

Long-term memory for AI agents. 92% R@10 on LoCoMo, which beats Mem0, Zep, Letta, and ChatGPT memory. Free locally; paid Engram Cloud tier syncs across every device with end-to-end encryption and team-shared spaces.

Persona

Open Source

Evolving personality for AI agents. Plutchik emotion tags, Big Five traits, and behavioral signals so models keep a coherent voice that grows with you instead of resetting every session.

Cortex

Open Source + Enterprise

Your company's knowledge as one searchable surface across Slack, Confluence, Notion, Jira, GitHub, Gmail, and Drive, with permission-aware retrieval and on-prem deployment. The enterprise wedge of the OneNomad stack.

Products

The AI platform, in detail

przm is the measurement layer. Pyre is the runtime. Engram, Persona, and Cortex are the cognitive layer. Same stack from a single user's laptop to a company's on-prem deployment.

v0.1
Open Source + CertWeb · CLI · GitHub

A vendor-neutral leaderboard for AI failure modes that don't have standards yet. Multi-agent convergence, sycophancy, memory recall. Deterministic scoring, Ed25519-signed receipts, no LLM in the grading loop. Open source; charter + per-release certification tiers for AI framework vendors.

Problem

Every AI framework vendor claims their agents are reliable. There's no third-party number to challenge or confirm that. The companies best positioned to build this benchmark (Patronus, Braintrust, LangSmith) sell into the same framework market, so publishing "this framework collapses to wrong answers" antagonizes their customers. The space needs a measurement entity that doesn't sell into it.

Approach

Built a deterministic scoring pipeline (no LLM in the grading loop) across multi-agent convergence and AI memory recall. Every result is an Ed25519-signed JSON receipt with methodology hash, fixture SHA, raw scores, and environment pin, committed to a public ledger. Anyone re-runs, anyone verifies. The vendor-cert tier turns the same harness into a third-party performance attestation framework vendors can publish on their own site.

Beta
Free / Pro / EnterpriseMac · Win · Linux

The control plane for local intelligence. Run open and frontier models on your machine, switch providers per conversation, keep memory and personality continuous across every device. Open-core, with Pro and Enterprise tiers.

Problem

Most chat apps lock you into one model and forget everything between sessions. Personal assistants don't know your business; enterprise AI tools don't respect your privacy. Teams want both, plus context that actually survives.

Approach

Built a cross-platform Electron app with a unified inference engine that speaks llama.cpp (local) and provider APIs (OpenAI, Anthropic, OpenRouter), an IPC bridge to Engram for memory and Persona for identity, and a per-conversation provider switch. Personal tier ships free; Pro adds cross-device continuity for agents, memory, and personality plus advanced multi-agent orchestration; Enterprise ingests company docs, code, calendars, and tickets with on-prem deployment, SSO, and audit logging.

Engram

Live
Open Source + CloudLocal · Cloud · Global

A long-term memory MCP server for AI agents. Hybrid retrieval across vectors, BM25, and a typed knowledge graph; episodic, semantic, and procedural layers that survive context-window compaction. Free locally; paid cloud tier for cross-device sync.

Problem

AI assistants forget every conversation the moment the context window fills. Each session starts from zero, with the same questions, same explanations, same setup work. And memory that lives only on one machine can't follow you between laptop, desktop, and phone.

Approach

Built a 9-stage hybrid retrieval pipeline backed by LanceDB vectors plus a typed knowledge graph. Pre-compaction handoff hooks dump session state to disk before context windows fill. Procedural rules surface based on emotional valence, recency, and outcome feedback. The hosted Engram Cloud tier syncs the same memory across every device you use, with end-to-end encryption and team-shared memory spaces.

Persona

Live
Open SourceGlobal · npm

An MCP server that gives AI agents a coherent, evolving personality. Plutchik-emotion tagging, Big Five trait modeling, conversation-style mirroring, and swappable soul files, so agents don't reset their voice every session.

Problem

Out-of-the-box LLM agents speak in a corporate-helpful monotone. Any personality you give them has to be re-prompted each conversation, and there's no path for them to grow into how you actually communicate.

Approach

Five-layer system covering personality, communication style, working style, a soul library, and behavioral signals. Persona reads user reactions (correction, approval, frustration, praise) and proposes evolutions over time with an explicit accept/reject flow so the agent doesn't drift unsupervised.

Cortex

Beta
Open Source + EnterpriseLocal · Cloud · On-prem

Universal memory + on-prem company-knowledge engine for AI agents. Ingests Slack, Confluence, Notion, Jira, GitHub, Gmail, Drive into one MCP-native, permission-aware retrieval surface. Personal free, Pro hosted, Enterprise on-prem.

Problem

Work knowledge sprawls across 8-15 SaaS tools. Glean and Microsoft Copilot for Work solve this only if your data lives in their cloud, which is a non-starter for legal, finance, healthcare, and any company with real data-sovereignty requirements. Permission-aware retrieval across all those sources is the missing piece nobody open-source has nailed.

Approach

Built an MCP server with workspace-scoped tenancy, hybrid retrieval, and ACL mirroring enforced at the database layer (Postgres RLS). Strips the bundled-LLM dependency in favor of an MCP enrichment-callback protocol. Your client (Pyre, Claude Desktop, anything MCP-speaking) supplies the LLM. Cortex supplies the memory and the connectors. The enterprise wedge of the OneNomad stack.

About

An independent software company
building in public

OneNomad LLC is a US-based software studio building the open-core AI runtime we wished existed: Pyre on the desktop, Engram for memory, Persona for voice, and Cortex for company knowledge. All local-first, all MCP-native, free for individuals and licensed for enterprise.

Alongside the AI platform we ship vertical SaaS and consumer products that use the same stack to solve specific problems: meal planning, trades quoting, D&D campaign management, board-game discovery, receipt splitting. Every product is in production, available globally, and run as a real business, not a portfolio piece.
