Large language models are genuinely extraordinary. What they can do with reasoning, writing, and analysis would have seemed like science fiction five years ago, and they're improving fast. But there's a gap between a powerful model and a personal assistant. Actually, there are three.
Personalization. Most AI products don't connect the dots. Your conversations persist, your history is there. But the knowledge stays siloed. Mention a project in one thread and a person in another, and nothing links them. The context you build never becomes structure.
Transparency. You send a message and get a response, but the steps in between are invisible. What context was loaded? What was remembered? What did the system learn? You're asked to trust the process without being able to see it.
Integration. AI assistants are isolated. They answer questions in a chat window, but they don't reach into your world (your calendar, the web, the information you actually need), and they don't bring what they find back into your context.
We built Aipa to close all three.
What Aipa Is
Aipa is a personal AI assistant built around the Nexus, a structured knowledge graph of your world. The models provide the intelligence. Aipa provides the personal layer: memory that connects and compounds, a process you can watch, and tools that tie into your life.
Personalization: The Nexus
Every AI assistant now remembers things, and that's real progress. But most store flat facts. "User prefers dark mode." "User works at Acme Corp." Isolated entries with no connections between them. Better than forgetting, but a long way from understanding.
The Nexus is a graph: entities connected by relationships.
When you mention Sarah from work, Aipa doesn't just file away "Sarah exists." It captures that Sarah leads Project X, reports to Mike, prefers morning meetings, and that you discussed the Q2 deadline with her last Tuesday. These aren't separate facts. They're connected nodes in a structure that mirrors how you actually think about your world.
What gets captured:
- People: colleagues, friends, family, and the relationships between them
- Projects: what you're working on, who's involved, key dates and status
- Preferences: how you like things done, from communication style to coffee order
- Places: where you work, live, and frequent, and what's relevant about each
Aipa doesn't force your world into rigid categories. Entities and relationships evolve naturally as your conversations add context. The way you think about a project in January might look different by March, and your Nexus reflects that.
Extraction happens continuously as you talk. Every time Aipa searches, creates, or updates something in your graph, you see it happen. Nothing changes in your Nexus without you being able to review it.
Transparency: The Pipeline
Every message flows through a visible pipeline: context loading, response generation, entity extraction, graph connection. You can watch each stage happen, see exactly what changed in your Nexus, and check your token usage. No hidden steps. We wrote more about the thinking behind this in Why We Show You Everything.
Integration: Tools and Flexibility
Aipa ships with a core toolkit and we're adding more:
- Web Search: Real-time results pulled into conversation
- Weather: Current conditions and forecasts
- URL Reader: Read, summarize, and extract key details from any page
- Nexus: Search and update your personal knowledge graph mid-conversation
Since this was written: timers, reminders, and files. Calendar is not built yet. Each tool feeds back into the Nexus: a weather check for your trip to Denver connects to the Denver node in your graph. Tools aren't isolated features; they're inputs to your growing context.
Aipa is free to start, with no credit card. When you want more, the Pro plan is $20 a month with generous usage included. Details on our pricing page.
Updated October 2026: this post first described a bring-your-own-API-key plan, which has been retired. The live view of every pipeline stage described in this post has also been replaced: when a reply saves something, the people, places, and things it touched now appear right under it.
What We're Building Toward
These three pieces (personalization, transparency, and integration) are designed to compound. A richer Nexus means better context for every response. Visible processes mean you can correct course when something's off. More tools mean more information flowing into the graph.
The goal is an assistant that doesn't just answer questions well. It answers them well for you, because it understands the specific web of people, work, and preferences that make up your life. And you can verify that it does, because everything is open.
Your data stays yours. We don't train on it, we don't sell it, and you can delete any of it anytime. Aipa is free to start, and paid plans are how it makes money: you pay for the service, and the service works for you.
