Beta — self-host nowThe brain.
The intelligence layer that powers every Joeybuilt product. Agents that remember, learn, and act across your entire digital life. Plexo doesn't just connect your apps — it thinks for them.
In memory of Joe “Joey” Ipson
Joe “Joey” Ipson was a self-taught engineer — Dustin's brother-in-law and his best friend. He shipped software real people relied on, and he worked from home so he could be present with his kids. He died at 38.
This company carries his name, and everything it ships is held to his standard: craft, presence, and building things that last.
Built in his name
Plexo is the AI agent platform underneath everything Joeybuilt ships. Semantic memory, domain reasoning through SCL, persistent agents, intelligent model routing. Not a wrapper — a runtime. Every product shares one brain, and that brain learns.
Vector-indexed, session-persistent, cross-product. Your agent remembers what worked three weeks ago and applies it today. No re-prompting. No context windows as a crutch.
The Semantic Context Lattice maps concepts, relationships, and regions in your domain. Plexo doesn't pattern-match against prompts. It reasons over structured knowledge.
Long-running, stateful, with tool access and channel presence. These agents don't answer questions and disappear. They hold context, execute multi-step workflows, and do the actual work.
The stack
Plexo handles intelligence. Koforje is where you write the code. Pushd gets it running. Three tools, purpose-built, no overlap.
The brain.
The intelligence layer that powers every Joeybuilt product. Agents that remember, learn, and act across your entire digital life. Plexo doesn't just connect your apps — it thinks for them.
The AI-native IDE.
LSP-native, agent-capable, built for the way software is actually written now. Your agents live where your code lives. Co-creation between you and AI, not bolted-on autocomplete.
AI-native deployment.
From code to production with agents that understand your infrastructure. Plexo-optional — AI features activate when connected. Built for the teams that want deployment to think.
Built on Plexo
Finance, documents, knowledge, productivity. Each one runs onPlexo's memory and reasoning. When Fylo learns your spending patterns, that context is available to Levio when it schedules your week. Same brain, different problems.
Predictive personal finance.
Connects your accounts, understands your patterns, predicts your future. Intelligent recurring transaction detection, merchant enrichment, AI categorization. Open source and self-hostable.
Everything flows here.
Document and digital asset management — the intake layer. Receipts flow to Fylo. Knowledge flows to Nexalog. Action items flow to Plexo.
Your second brain, with a backbone.
Personal knowledge management built for how you actually think — not how note apps want you to think. All intelligence powered by Plexo.
Email, tasks, and calendar — unified.
Gmail and Outlook sync, AI scheduling, intelligent task management. Built to do what the current generation of productivity tools can't: think.
Every Joeybuilt product is open source and self-hostable. But you don't need a server to get started. Sign up and start using the managed version immediately — we handle the infrastructure so you can focus on the work.
Joeybuilt LLC is the official hosted provider for all products. Open source under AGPL-3.0 and MIT — read every line of code on GitHub.
