Vasa SerafinChat, on the web and in the app
The same assistant, reachable from a browser at nexusagi.thetooltuckshop.rs or from the free Android app.
Honest, plain-English
What NexusAGI can do today
This page exists so you never have to guess. It says what NexusAGI is, what it actually does right now, what it does not do yet, and how the free access works — no marketing language, no invented statistics.
What NexusAGI is
NexusAGI is a private assistant that runs on its operator's own hardware. Your conversation is not sent to a third-party cloud service to generate its replies. It keeps learning from what it is taught, and when it does not know something it says so rather than guessing a plausible-sounding answer.
What it does today
Teach it, and it remembers
Tell it a fact and it stores it in its own knowledge graph, to draw on in later conversations.
Learns from feedback
Correcting it or confirming an answer feeds back into how it responds next time.
Sessions and usage tracking
See which devices are signed in, follow a session from your phone, and check your usage.
Definitions and explanations
Across the knowledge branches it holds — general knowledge, science, and more — built from what it has been taught and has ingested.
Maths, science and language curriculum
Curriculum-style knowledge across arithmetic, algebra, geometry, physics, chemistry, biology and English.
Code questions
For the programming languages it currently holds rules for (including C#, Java, Python, JavaScript, PowerShell and Kotlin).
Terminal follow, in the app
Start a session on your computer and follow its terminal from your phone — the app can send messages back but cannot run anything on that computer.
The numbers
Measured directly from the running system, not estimated, and rounded down so nothing here overstates it:
Runs on private hardware
It runs on its operator's own machine, not on a rented cloud AI service.
Honest about gaps
When it is not sure, it tells you instead of making something up.
Learns what you teach it
Corrections and new facts you give it are remembered for next time.
Rule and flow counts include disabled rules that are excluded from active use. Source: the
live system's own /api/health, /api/rules/effect-coverage and
/api/rules/graph/flows endpoints, measured 6 September 2026.
What it does not do yet
- No image generation. NexusAGI does not create pictures. (See "What's coming" below.)
- No web browsing by default. It answers from its own knowledge graph, not by fetching live pages, unless a specific feature is explicitly enabled for that.
- Benchmark scores are being re-measured honestly. An earlier internal check found that some of NexusAGI's own claimed benchmark results did not hold up under a fair re-scoring. Rather than publish a number we are not confident in, we are re-measuring properly — so this page does not quote an accuracy percentage. When there is a number we trust, it will appear here with how it was produced.
How free access works
Website
1 free day of chat after you sign up, no card required.
Android app
7 free days from the first time you open the app.
Then
The subscription is from AUD 0.99/month (basic, plus or pro), billed through Google Play, and unlocks the web chat, the Android app and the CLI together.
Privacy, in one paragraph
NexusAGI runs on the operator's own hardware; your conversation is not relayed to a third-party AI provider to be answered. The Android app declares exactly what it collects and why, including the owner-verification camera/microphone feature it is not yet using in this build. Read the full detail in the NexusAGI privacy policy.
What is coming
These are plans on the development queue, not promises of a date:
- Its own image generator — it draws objects from what it has learned about their parts, shape, colour and size.
- Arduino and temperature-sensing support — reading sensors and working with microcontrollers. Planned for a later update.
- Automatic updates — the CLI checking for and installing new versions itself.
