§ Two things I built
werbos is my own AI, built from scratch and run on my own hardware. werbos.design is a site generator with no AI in it at all.
The AI
werbos
A local-first AI agent system I built from scratch: agent loop with tool calling, RAG, memory, an eval harness and LoRA fine-tuning, all on open-weight models. Off-grid by default, and it never phones home. Every day of the build is written up in a public log.
The website builder
werbos.design
Describe a site and get a finished, on-brand page back, composed deterministically from a brief: the same brief makes the same site, offline, for about $0 a build. No templates to pick, no model to pay for.
Then I dogfooded it: every section of this page came out of werbos.design. See the brief it was built from.
§ How this page was made
No template and no hand-written markup. The words are mine; the page came out of werbos.design, a site generator I wrote, from the brief shown here. No LLM and no API key: the same brief makes the same site, every time.

§ Projects
56 projects
A local-first AI assistant, built from scratch
Agent loop with tool calling, RAG, memory, an eval harness and LoRA fine-tuning. It runs entirely on open-weight models on hardware I own, with no hosted LLM calls. Most of the other AI projects here are pieces of it or were built around it.
The code is private. Ask for a walkthrough.
Hold a key, talk, and clean text lands wherever your cursor is
A clean-room dictation app in the style of Wispr Flow. Hotkey → mic → whisper.cpp running locally on Metal → optional Claude cleanup → pasted into the focused app (Terminal, Slack, Word, anything).
Learn Spanish by speaking it, fully offline
A path of 24 units and 240 phrases, graded word by word as you say them out loud, plus Sofía: an on-device AI conversation partner (Qwen 3B via llama.cpp) who speaks sentence by sentence while she is still writing, with a separate checker quietly correcting your grammar. Mac and Android.
The code is private. Ask for a walkthrough.
A recursive LLM generation engine
You describe a pipeline as a recipe: a stack of levels, each with a prompt and an output shape. Each node, plus everything above it, runs through the next level's prompt and becomes that level's children. Runs are resumable and editable. One runner covers world bibles, screenplays, novels and albums. Ships as a CLI, a library and an HTTP API.
The code is private. Ask for a walkthrough.
Point it at a running web app and it writes the user manual
It explores the live UI like a first-time user, using only the rendered DOM, the accessibility tree and screenshots, and never reads the source. If a feature can't be discovered by using the app, it doesn't get documented, which is the same limit a real user has.
The code is private. Ask for a walkthrough.
Inbound phone calls become AI conversations
A headless backend. Twilio bridges the call, werbos runs the brain, and Kokoro speaks the reply.
The code is private. Ask for a walkthrough.
Trace inspector for an AI agent
When a skill misbehaves (wrong math, off-topic results, a fumbled tool call), you ask glasshouse what happened instead of digging through seven log files.
The code is private. Ask for a walkthrough.
Agent-loop primitive: think → act → observe
Backend-agnostic, dispatches tools, has zero runtime dependencies and follows a versioned spec. Named for Walter Pitts (1923–1969).
The code is private. Ask for a walkthrough.
Eval primitive: grade subjects against suites of probes
Produces reports. It is the counterpart to pitts in the McCulloch–Pitts pair, with zero runtime dependencies and a versioned spec. Named for Warren McCulloch (1898–1969).
The code is private. Ask for a walkthrough.
Observe, summon, defend and signal: an orchestration layer as four protocols
Four protocols: observe (see), watchtower (triggers, dispatch and audit), warden (rules and alerts) and beacon (probes and state transitions). Each has a normative SPEC, a reference Python library and conformance tests (98 for observe, 89 for watchtower). It ships as a Docker Compose stack with a React dashboard.
The code is private. Ask for a walkthrough.
121 graded knowledge libraries, ~15k cards
The content layer for werbos, kept separate from the engine. Graded card libraries span code, security, math and more, and are generated and validated with a fixed schema and a dedupe step.
The code is private. Ask for a walkthrough.
A forest of tiny models instead of one big one
A research thread: instead of one model that knows everything, a retrieval forest of tiny models that each know one thing. One finding: an offline model enriching the library raised small-stack recall from 3 to 9. Results are frozen alongside the code.
A YouTube MCP server, built twice from one spec
A YouTube MCP server plus a retro YouTube-clone web app. Two implementations live side by side as a bench test of building from a single SPEC.
The code is private. Ask for a walkthrough.
A one-paragraph brief becomes a polished marketing site, with no LLM
A deterministic website generator that runs offline with no API key, at about $0 per build. It has a React + TypeScript builder and outputs framework-free, self-contained HTML.
The code is private. Ask for a walkthrough.
A one-sentence thesis becomes a full song
Thesis + vibe → a curated cross-book scripture chain → Claude → lyrics, chord progressions and guitar tabs, plus Suno-ready files for AI music generation.
The code is private. Ask for a walkthrough.
Bitcoin market analysis paid with Lightning micropayments
Signals and analysis built on technical indicators and on-chain metrics, with content unlocked from 21 sats over Lightning. Premium tools (Trade Coach, Chart Analysis) use Claude. 1,200+ commits.
The code is private. Ask for a walkthrough.
Mine Reddit and Hacker News for problems worth solving
Scrapes both sources, scores each complaint 0–100 on frustration signals, and runs optional AI analysis covering category, market size, existing solutions and product ideas.
The code is private. Ask for a walkthrough.
A scrum board you can drive from an AI agent
Kanban across multiple projects, a scanner that detects each stack and files todos for what's missing, and a Claude Code skill for updating the board in plain English. Stored in SQLite, no server needed.
A living-town life sim with AI-driven residents
The PC Sims experience, native, with residents powered by werbos's NPC brain. A pure, headless-tested simulation core drives two renderers (isometric 2D and 3D). Playable vertical slice.
The code is private. Ask for a walkthrough.
Bookkeeping and a household budget, on your own computer
Bank feeds (Plaid/SimpleFIN), invoices, bills, reports and tax prep for a small business, plus budgets and savings goals for the home, all in one file you own. A live product with paid plans and signed, auto-updating installers.
A writing desk for working a script over
Onion-skinned drafts, A/B versions, reorderable blocks, Obsidian-style notes, local narration and dictation, and an MCP server so AI agents can edit manuscripts. Installers for Mac and Windows.
A modern Winamp that visualizes whatever your computer is playing
It plays nothing itself. It taps system audio (Core Audio process tap, WASAPI loopback, PulseAudio monitor) and runs the classic spectrum analyzer, Milkdrop presets, song identification and karaoke on top of YouTube, Spotify, anything. macOS, Windows and Linux.
Snap blocks together, then flip them over to read the real code
A visual coding platform for kids: every block is real JavaScript or Python underneath. Write your own function and it becomes a block with your name on it, which you can publish to the Shareplace marketplace. 164+ blocks across 16 categories, including cryptography and AI. 700+ commits.
Read the four gospels at four depths, as a diff
A Bible study tool that reads a passage at four layers (historical, literal, and more) and treats the gospels as something you can diff, with lemmatised Greek, a drawn map, and the material world of the text.
One timeline linking passages across ancient texts
Ingests the Tanakh, KJV, Quran and other texts, extracts every named person and place, and emits one static timeline.json where each event is anchored once and points to every passage that describes it, disagreements included.
The code is private. Ask for a walkthrough.
A household budget organized by people, not categories
Asks "can I say yes to this right now?" rather than "where did my money go?". Each slice of the month belongs to a person and gets a time-aware status light: $200 into a $400 envelope is fine on the 15th and a fire on the 3rd.
The code is private. Ask for a walkthrough.
A BOLT12-native Lightning wallet
A privacy-focused Lightning wallet for Android on the Breez SDK: BOLT12 offers (static payment codes), multiple wallets, optional community-node routing and biometric auth.
A 2FA authenticator with folders
Like Google Authenticator, but with folders. No accounts, no cloud sync, codes kept in iOS Keychain / Android Keystore, and a one-scan import from Google Authenticator.
The code is private. Ask for a walkthrough.
Find duplicate photos and organize the rest
Scans folders, finds exact duplicates with SHA-256, files photos into YYYY/MM folders, and moves duplicates aside for review. Freemium with license keys.
A GPS walking-tour passport for the parts of a city that don't make the top-ten list
Walk the real streets. When you get within range of a plaque, mural or landmark tree, your phone's GPS confirms it and the app stamps your passport. The pilot is Auburn, CA, but what's really being built is an engine that works for any city.
The code is private. Ask for a walkthrough.
+0 HP, +0 TQ, +100 smiles
Reads live engine data from a 2001 Lexus IS300 over OBD-II (ELM327 Bluetooth) and plays layered turbo and engine sounds that react to how you drive.
The code is private. Ask for a walkthrough.
A GTA2-style top-down open world
Drive, shoot, run jobs for three rival gangs and survive a six-level police response. All art is original and generated procedurally by a script in the project.
The code is private. Ask for a walkthrough.
32 harmless office pranks in one script tag
Drop it into any page and watch coworkers question reality. Each prank fires once per victim, so refreshing won't save them.
Private, verifiable voting with no trusted authority
Voter privacy, vote integrity and public verifiability without trusting any single party, using blind signatures, zk-SNARKs, threshold cryptography and Merkle trees. Benchmarked at 1M voters in 3m 33s. The whitepaper is public.
Forms the server can't read
Submissions are encrypted in the browser before they are sent, so the server never sees plaintext.
Blind-signature credentials
An implementation of Chaum's blind signature protocol: authorities sign credentials without learning their contents. Signed credentials can't be linked back to the request, and nullifiers prevent double use. REST API.
The code is private. Ask for a walkthrough.
Bitcoin-grade immutability without the blockchain baggage
A Merkle-tree ledger service: verifiable, append-only storage for audit logs, compliance records and anything that needs to be tamper-evident.
The code is private. Ask for a walkthrough.

The code is private. Ask for a walkthrough.
A small SSO server: passkeys and OpenID Connect
WebAuthn passkeys, OpenID Connect and Ed25519 signing, built to be readable decades from now. The demo is one HTML file: log in with a real passkey and watch your identity come back with "✓ valid signature".
The code is private. Ask for a walkthrough.
An API security workbench
Capture, explore, sequence, fuzz, diff and replay API traffic. It has a built-in mitmproxy proxy, a visual sequence editor, role diffing, a type-mutation fuzzer and invariant testing. Import any OpenAPI spec or capture live traffic.
The code is private. Ask for a walkthrough.
A zero-knowledge .env manager
"Sync secrets. Not trust." An Angular app, a backend and a CLI for sharing environment files without the server ever reading them.
The code is private. Ask for a walkthrough.
A zero-knowledge knowledge base of attack vectors
Encrypted storage of offensive-security knowledge for security teams, built on VeilCloud.
The code is private. Ask for a walkthrough.
Your own Cookiebot, self-hosted
