## Castello

Castello positions itself as an "investing copilot" for retail investors who want institutional-style analysis without an institutional budget. The core idea is consolidation: rather than checking a brokerage app, a screener, a news site and a spreadsheet separately, you link accounts read-only and get every holding, price move and allocation shift in one calm dashboard. From there the product adds intelligence on top of the data — AI-generated sentiment from news and filings, technical and fundamental readouts per ticker, and a risk engine that scores exposure and flags concentration you may not have noticed.

The workflow is deliberately linear. Connect your portfolio, search and analyze any stock, read a feed tuned to your positions, track performance across accounts, then assess and rebalance risk. Because connections are read-only by design, Castello acts as an analyst rather than a broker: it never executes trades. A companion iOS app, Castello: Investing Copilot, extends the same view to mobile and is currently offered in early access on the App Store.

CastelloAI was founded by financial analysts and AI engineers, and its parent company Transcrypts has raised a $20 million seed round. The team's stated mission is to bring Wall Street-grade tooling — portfolio analytics, risk monitoring, market research — to everyday investors, and the roadmap leans on AI to compress hours of manual research into a few minutes of reading.

**Pricing & Plans:** Castello's tool record is tagged Free, and the core experience — connecting a brokerage, viewing your consolidated portfolio, searching tickers and reading the personalized feed — is available to download and try at no charge. The iOS app is in early access on the App Store. Castello does not publish a detailed public pricing table on its main pages, so treat any paid tiers or premium research features as subject to change and confirm current terms on the official site.

- **Unified portfolio view:** Link supported brokerage accounts read-only so every holding appears in one live view without manual data entry.
- **AI stock and market analysis:** Look up any ticker for live pricing, fundamentals and technical indicators, enriched with AI sentiment drawn from news and filings.
- **Risk and concentration scoring:** A risk engine that scores exposure, flags hidden concentration and monitors diversification so drift is caught early.
- **Personalized news feed:** A daily feed tuned to the stocks you own and watch, surfacing stories that actually move your portfolio instead of generic market noise.
- **Performance tracking:** Follow returns, income and allocation drift across accounts with daily, monthly and since-inception charts.

**Strengths:** Consolidates every brokerage holding into one live dashboard, removing the need for manual spreadsheets; Combines market data, fundamentals, technicals and AI news sentiment in a single research screen; Risk engine highlights concentration and diversification drift before it becomes a problem; Personalized feed filters market noise down to stories relevant to what you actually own

**Limitations:** No Android app at launch; the iOS app is still listed as early access; Advanced or institution-level analytics can feel lighter than full desktop research terminals; Read-only brokerage connections mean you cannot place trades from inside Castello; Some features depend on linking accounts, so value is limited for investors who keep portfolios offline

## Moontower

Moontower positions itself as AI-powered volatility intelligence rather than a generic screener. Instead of reselling third-party data, it computes its own volatility surfaces, derives the downstream metrics itself, and renders them in a set of opinionated charts spanning a cockpit, dashboard, trade ideas and drill-down views. The result is a platform that speaks the language of professional vol traders while staying usable for individuals.

The headline feature is the Moontower Agent, an AI assistant that answers questions such as whether a name's volatility is cheap or rich into earnings, which stocks have the richest skew against their own history, or how to price a zero-cost collar. Answers are grounded in market data with sentence-level citations, and the team stresses that prompts and documents are never used to train models, with audit logs available for Enterprise. Structured workflows for income, defensive and collar strategies turn that context into trades.

For developers and quant workflows, Moontower runs a hosted MCP server. Adding it with one command gives Claude Code and other MCP clients 16 typed tools covering implied vol, skew, constant-maturity IV, option chains, trade ideas and cockpit statistics, authenticated via OAuth or an API key. Moontower reports 5,000+ traders, 500+ monitored assets, 52 proprietary charts and more than 100 million tokens processed per month.

**Pricing & Plans:** Moontower uses a freemium model with a free sign-up tier and paid plans for individuals and firms; enterprise features such as audit logs and the funding suite are available. The hosted MCP server is included on every plan at 2 credits per call. Exact prices are best confirmed on the site or via a demo.

- **Proprietary vol surfaces and charts:** Moontower computes its own volatility surfaces, derives downstream metrics and presents them in 52 proprietary charts covering a live dashboard, cockpit, trade ideas and drill-down views.
- **AI agent with cited answers:** The Moontower Agent answers questions like whether NVDA vol is cheap into earnings, grounding every claim with sentence-level citations from market data, research or your firm's own knowledge base.
- **Trade workflows:** Workflow templates for income (covered calls, cash-secured puts), defensive defined-downside exposure and collars including zero-cost collars map market context to concrete structures.
- **Hosted MCP server:** A hosted MCP server exposes 16 typed tools — implied vol, skew, constant-maturity IV, option chains, trade ideas and cockpit statistics — to Claude Code and other MCP clients over HTTP.
- **Cross-asset screening:** Screen across equities, ETFs, crypto and more for rich or cheap variance risk premium, IV rank and skew relative to each name's own history, while filtering by earnings dates and liquidity.

**Strengths:** Computes its own volatility surfaces rather than reselling third-party data.; AI answers come with sentence-level citations, which builds trust for trading decisions.; MCP server gives Claude Code and other agents direct, typed access to options data.; Covers multiple asset classes and workflows including income, defensive and collar strategies.

**Limitations:** Serious options analytics carry a learning curve for beginners.; Full desk-grade features and the funding suite are aimed at firms and may require a demo or higher-tier plan.; Output is strictly educational analytics, not investment advice.
