What is Infi?

Infi is a desktop app that lets you research stocks and portfolios using AI coding agents. The agent fetches data, structures every claim as a source-backed block, and submits it through Infi's tools — the report is assembled from those typed blocks, never parsed from free-form prose.

Every analysis includes a thesis, risks, scenarios, and a final stance — all citing their sources.

Core Features

Structured Research

• Thesis and risk blocks with source citations
• Scenario analysis (base, upside, downside)
• Final stance with confidence level and rationale
• Projections with bull/base/bear price targets

Portfolio Analysis

• CSV import for holdings and transactions
• Allocation review across asset class, sector, geography
• Risk assessment: factor exposures, macro sensitivities, tail risks
• Rebalancing suggestions with scenario comparisons
• Portfolio-level expected return modelling

12 Data Providers

• Tavily, Brave Search, SEC EDGAR, Alpha Vantage, Financial Modeling Prep
• Finnhub, Polygon, Yahoo Finance, NewsAPI, Finviz, StockTwits, Hacker News
• API keys stored in your OS keychain; providers without keys are excluded

Export & Share

• Standalone HTML export (interactive viewer)
• Markdown export
• Publish to PageDrop.io with a shareable link

Privacy-First

• Local SQLite storage — no cloud, no account, no telemetry
• API keys never leave your machine

Supported Agents

Infi works with multiple AI coding agents via the Agent Client Protocol (ACP):

Claude	Codex	Gemini	Kimi	Mistral	OpenCode	Qwen

You can also use any custom agent via INFI_CUSTOM_AGENT and INFI_CUSTOM_AGENT_ARGS.

Installation

Homebrew (macOS)

brew install --cask khanhthanhdev/tap/infi

Windows / Linux

Download the latest installer from GitHub Releases.

From Source

git clone https://github.com/khanhthanhdev/infi.git
cd infi
cargo run

Requires Rust (stable toolchain) and Bun for the frontend build.

Development Setup

Prerequisites

• Rust — stable toolchain (managed via rust-toolchain.toml with rustfmt and clippy)
• Bun — frontend package manager and runner

Quick Start

# 1. Clone the repo
git clone https://github.com/khanhthanhdev/infi.git
cd infi

# 2. Install frontend dependencies
cd frontend && bun install

# 3. Start the frontend dev server (hot reload)
bun run dev

# 4. In a separate terminal, run the Tauri app
cd ..
cargo run

Frontend Commands

Command	Description
cd frontend && bun install	Install frontend dependencies
cd frontend && bun run dev	Start Vite dev server with hot reload
cd frontend && bun run build	Type-check and build for production
cd frontend && bun run build:viewer	Build standalone HTML viewer (for export)
cd frontend && bun run check:ci	Biome lint + format check (zero warnings)

Rust Commands

Command	Description
cargo run	Run the Tauri desktop app
cargo check	Validate compilation
cargo test	Run all tests
cargo fmt	Format code with rustfmt
cargo clippy --all-targets --all-features -- -D warnings	Lint (warnings = errors)

CI Validation

All checks must pass with zero warnings before committing:

cd frontend && bun run check:ci   # Biome lint + format
cd frontend && bun run build      # TypeScript type-check
cargo fmt --check                 # Rust formatting
cargo clippy --all-targets --all-features -- -D warnings  # Rust lint
cargo test                        # All tests

Environment Variables

Variable	Purpose
INFI_DB_PATH	Override SQLite database path
INFI_CONFIG_PATH	Override app config path
INFI_MAX_METRIC_AGE_DAYS	Data freshness cap (default: 365)
INFI_CUSTOM_AGENT	Custom ACP agent binary
INFI_CUSTOM_AGENT_ARGS	Arguments for custom agent
INFI_SRC_KEY_<PROVIDER>	Data source API key (e.g., INFI_SRC_KEY_ALPHA_VANTAGE)
