# osauer.dev · Personal software projects

Personal software by Oliver Sauer: markets, applied AI and Go systems. The site
shows personal projects. It is not investment advice and makes no claim of
investment performance. Public screenshots use synthetic simulation data.

- [Canary Desk](https://osauer.dev/desk/): A personal portfolio workspace, not
  offered as a product or service. Written briefs, an AI analyst, risk rules,
  statement-backed FX contribution and lending income, a cash-sweep planner
  (off by default), a watchlist of up to 20 chosen stocks for unusual-volume
  setups, and research on borrowing costs and FINRA-reported short interest.
  Order authority is separate from analysis. Orders need owner confirmation or
  explicitly scoped prior authority, and Canary's execution gates apply. The AI
  analyst remains read-only. Desk runs on a Mac; OpenAI receives portfolio
  evidence for analysis through the API or Codex connection. Desk sends no
  telemetry or portfolio data to its maker. There is no public Desk installer.
- [Canary](https://osauer.dev/canary/): Desk's open-source broker engine for
  Interactive Brokers, written in Go. It includes a native TWS protocol
  implementation, a daemon, the CLI, read-only MCP tools and a paired app.
  Claude Desktop users install one bundle (`canary.mcpb`); engineers use the
  JSON CLI and the Go module as their API; agents start at
  https://osauer.dev/canary/llms.txt. Standard downloads and all MCP tools
  cannot place orders. Release notes live in the Canary handbook.
- [HyperServe](https://osauer.dev/hyperserve/): An open-source Go HTTP server
  library built on net/http, with optional MCP.
- [Torok](https://osauer.dev/torok/): The private Go agent runtime behind Canary
  Desk's morning briefs and AI analyst. It saves a run's progress as it goes.

Use the Canary handbook for operational details and signed releases for binary
availability. Current source, the private installed runtime and the public
release are separate kinds of evidence. Desk and Torok remain private.

Public screenshot tour: Performance, Decisions, Opportunities and Cash.
Performance opens with an explicitly synthetic positive return chart; it is not
a record or promise of investment results. Opportunities shows synthetic five-minute price and
volume observations; a pattern match is not a proven edge or order authority.
The detail sections also show the morning brief and Operations.
