Model Details

What Runs on Your Phone.

Everything Angrove does happens on the iPhone in your hand. Here is what that involves, how it reasons, and where its limits are.

Language model
The current development build uses a fine-tuned Gemma 4 E2B model.
Where it runs
On your iPhone's GPU, using Google's LiteRT-LM runtime. No server is involved in answering.
Size
The current model package is about 3.86 GB. The release model may change before launch.
Memory of a conversation
About 4,000 tokens of working context. /compact summarizes older turns when a conversation runs long.
Search and the Insight Tree
A small on-device embedding model (MiniLM) that measures how close two ideas are in meaning.
Tested on
iPhone 17, with 8 GB of memory.
Network
None. The app makes no network requests to answer a question or build your Insight Tree.

Still changing. Angrove is evaluating a Gemma 4 E4B package on the same LiteRT-LM runtime. It has not replaced the current app model, and its published package has not been confirmed as QAT. Final model and device requirements will be set after phone testing.

Two jobs, kept apart

Trained for How It Reasons. Grounded for What It Says.

Fine-tuning shapes Angrove's behavior and voice: how it weighs an argument, how it answers, how it admits uncertainty. It isn't how facts get in.

For questions that depend on a text, Angrove searches the Library on your phone and brings the relevant passages into its answer. The Library is reference material, not training data.

Defining Justice

How does Aquinas define justice?

Aquinas takes the jurists' definition and restates it in his own terms: justice is a settled habit of the will, rendering to each person what they are due, steadily and for good . Because it is about what is owed to another, it is the virtue that orders us toward others.

Moral theology · Summa Theologica

“Justice is a habit whereby a man renders to each one his due by a constant and perpetual will.”

II-II, Question 58, Article 1

Model tasks

One Task at a Time, in the Open

Everything the model does runs through one queue you can see. Your questions and definitions come first. Updating the Insight Tree waits until you've paused, and steps aside when you ask something new.

Tap the status in the dock to see what's running, reorder what's next, or cancel it.

The standard

A Rigorous Conversation Partner

Every conversation follows the same standard, whatever tone you choose for it.

Strongest Version First

Your argument is represented at its most reasonable before it is questioned.

Name the Real Problem

A bad inference is told apart from a disputed premise or missing evidence.

Revise When Warranted

When your reasoning holds, conclusions change, and so does everything that depended on them.

Proportional Confidence

How sure an answer sounds should match the evidence behind it.

How it answers

Depth When It's Needed

Routine Questions, Answered Directly

Simple questions take a fast path straight to the answer.

Hard Questions, Reasoned Through

Complex questions get deeper reasoning, with a short note on the approach taken. You see the approach, never raw scratch work.

Fails Honestly

If the model can't produce a valid result, the action fails and offers a retry. It never fills the gap with canned or made-up content.

Limits

What It Isn't

It Can Be Wrong

  • A phone-sized model makes mistakes, including about sources and quotations.
  • The Library is fixed and focused. When a question depends on a text it doesn't hold, Angrove should say so rather than invent one, but check anything that matters.

It Isn't a Counselor

  • Angrove is for private study and reflection.
  • It is not a substitute for professional counseling, spiritual direction, or clergy.
