What's inside

Scenario Engine

10,000-path Monte Carlo with block bootstrap. Probability fan charts at 50%, 80%, 95% bands. Horizon table from 1 day to 5 years.

Historical Engine

12-event playbook (2008 GFC, 2020 COVID, 2023 SVB, 2024 yen unwind…). Drawdown + recovery analysis. Fama-French factor decomposition.

Regime Classification

4-D growth/inflation/liquidity/sentiment features. K-means + HMM ensemble. Historical analog matching via cosine similarity.

ML stack

Random Forest, XGBoost, LightGBM, LSTM, PatchTST, Bayesian regression, GP — every output is a distribution, never a single point estimate.

AI commentary

Local Llama 3 8B via Apple MLX. Optional Anthropic Claude via Atlas Live. Optional Apple Foundation Models on macOS 15+.

Stress tests

Six built-in stress scenarios. Rates +100bps. Equities -20%. Oil -30%. USD +10%. Taiwan crisis. US recession.

Your data never leaves your Mac.

Atlas is software you run on your own machine, on your own data. Two specific exceptions, both opt-in:

  1. Live data refresh (Atlas Live subscribers): we proxy Yahoo Finance + FRED + central-bank data through our Cloudflare Worker. We send only the ticker symbols, never the weights, names, or analysis.
  2. Cloud LLM commentary (Atlas Live or your own API key): a scenario summary is sent to Anthropic Claude for narrative commentary. No holdings list, no portfolio name.

No telemetry. No analytics. No usage tracking. Ever.

FAQ

Does Atlas forecast stock prices?

No. Atlas produces probability ranges from historical data and Monte Carlo simulation. Every output is framed as a scenario, not a forecast.

Do I need an internet connection?

Only for initial data download and Atlas Live features. Otherwise everything runs offline on your Mac.

What Macs are supported?

Apple Silicon (M1 or later), macOS 14+. We recommend M4 Pro 24GB or higher for the full ML stack.

Is there a refund policy?

14-day free trial means you can fully evaluate before paying. After purchase, contact support for refund requests within 30 days.
