Tech Overview

What StudiOn is

StudiOn is a private AI workspace for Macs with Apple silicon, now in private beta. It brings conversations, documents, spreadsheets and source-cited answers into one native app. Privacy is the default, not a setting you have to find.

Jimmy and Neutron Engine

Jimmy is the assistant in StudiOn. Underneath is Neutron Engine, built from scratch for Apple silicon on the architecture of a game engine: an entity component system, a work-graph scheduler and Metal 4, with no legacy code paths. A game engine for AI. Today the engine runs Jimmy’s conversations, documents, retrieval, context and tasks. Next, the rest of the heavy work moves inside it, so StudiOn uses your Mac the way a game does.

• Models become swappable parts. The engine loads them, schedules them and swaps them, so a better model drops straight in.
• One memory budget. CPU and GPU share one pool of memory, and models stream in and out the way games stream textures.
• The right core for the job. Background work goes to the efficiency cores, and the answer you’re waiting on goes to the performance cores.
• The same engine is built to power other NeutronTech apps, each with its own identity and rules.

Documents and checked answers

StudiOn preserves imported originals and conversation records locally. Its document workflow includes source references, complete-document review, on-device text recognition for scanned PDFs, spreadsheet worksheets, and checked calculations. Coverage and extraction limits matter: a source reference does not guarantee that an answer is correct.

• It reads PDF (scanned pages included), Word (.docx), Excel (.xlsx), CSV, TSV, RTF, Markdown, JSON and plain text.
• Long documents are read start to finish. A whole-document review records what it covered.
• Open a citation to see the cited section highlighted in the file, or the cited rows in the spreadsheet.
• Format-aware processing extracts document text and spreadsheet data before selected evidence enters an answer.
• If StudiOn can’t read part of a file, it tells you instead of pretending it read everything.
• Calculations run as real data operations. Jimmy’s reading of what they mean can still be wrong, so the cells it used are always shown.

Local model and Mac requirements

StudiOn ships with Gemma 4 built in, running through MLX on Macs with Apple silicon and macOS 26 or later. There is nothing to download and it doesn’t need Apple Intelligence. More models, and a library that shows which ones fit your Mac, are on the way.

• The model’s working memory isn’t a fixed number. It’s set from the model and from your Mac’s memory, so the same app does more on a bigger Mac with nothing to configure.

Conversations with a record

StudiOn stores conversations and sources locally so they survive restart. Conversation management includes branching, retrying, archiving, and Markdown export. Original messages and imported source bytes remain separate from replaceable indexes and summaries.

• Context is sized to your Mac, not fixed. Neutron Engine reads how much the model can hold and how much your Mac’s memory allows, and uses that. A Mac with more memory holds more of the conversation at once.
• Long conversations are condensed as they grow. Your full conversation stays saved on your Mac, and Jimmy carries your corrections and open tasks forward and brings back earlier details when they matter.

Permissions and bounded tasks

Jimmy works only with what you give it. The model can’t grant itself access, and it can’t declare that a task succeeded: the app checks.

• Only the sources you choose go into a task.
• You see progress, can stop a task while it runs, and see its results and any failures.
• Editing and creating documents is on the roadmap, with every change shown to you before it’s applied.

Local data work, with honest boundaries

StudiOn includes spreadsheet worksheets and checked calculations over supported data. Deeper extraction and comparisons across sources are on the roadmap.

• A checked calculation does not make this an Excel formula engine or guarantee Office round-trip fidelity.

Permissioned online work

Local work does not require a cloud AI service. Optional web research is planned and would require permission to send a search request online. It isn’t part of the private beta.

• An approved online search can disclose information included in its query.
• When search arrives, every result will show where it came from and when, kept apart from your local work.

Your data lives on your Mac

Conversations and files stay on your Mac. StudiOn goes online only to check for updates and to send feedback you choose to send. Neither includes your workspace. Update checks can be turned off in Settings. Feedback includes only what you choose to submit and the technical details shown in its window.

• Each feedback message, and any file attached to it, is deleted automatically one year after it arrives. Cloudflare stores feedback for NeutronTech.
• Archiving a conversation hides it. Deleting it from Trash erases the conversation for good. Files you added stay in your Library until you delete them there, which removes the file and everything StudiOn made from it.
• Help → Send Feedback sends the kind of feedback, your message, an optional reply email and any file you attach, plus the app version, build and a random install code not linked to you. Unless you turn off Include build and Mac details, it also sends app and engine source revisions, macOS version and Mac model. The window shows exactly what will be sent. Nothing from conversations or files is included unless you type or attach it.

From answers to finished work

These are plans, not features you have today.

• Next. Recordings and video, transcribed on your Mac and cited to the moment, with voice notes and dictation. A second built-in model, then a library that shows which models fit your Mac. Text in photos and images, and more document formats. Web search, only when you ask. Questions and calculations across all your sources.
• Later. Calls and meetings in any call app, recorded only when you say so, with notes and action items cited to the moment. Documents edited and created, every change shown first. Talking with Jimmy out loud. Understanding images and video. Workflows that run on their own without changing your originals. StudiOn for whole companies. Your Macs working together to run larger models. Teaching Jimmy your work, privately.
• Underneath. The rest of the heavy work moves inside Neutron Engine before the bigger features arrive, so they build on a finished engine.
