About
A library with a desk attached.
PromptTape is the hybrid: prompts you can paste, a leaderboard of what other readers actually use, and the stacks that feed them. It is built for retail investors who read filings, not for a chat room.
Prompt library
Paste-ready instructions for earnings calls, filings, portfolios, the open, screens, and the guardrails that keep a model from inventing a number. Each one names the inputs, the output, and what to do when the source is silent.
Leaderboard
Readers copy and upvote. The home board ranks this week's copies and this week's upvotes from the seed plus whatever has happened since. It is a usage board, not a research ranking.
AgentDesk stacks
A stack pairs a job with the tools and MCP servers that should be open beside the prompt: Fiscal.ai, Quartr, Koyfin, earnings.chat, Alpaca MCP, OpenBB. The prompt is the last step, after the source is on the page.
Tape Drop
A short email list for when the desk adds a prompt or a stack. It is not a signal service.
Not financial advice
PromptTape is an educational prompt library for researching public companies. A prompt is a writing instruction, not a recommendation to buy, sell, or hold any security, option, or other instrument. You can lose money. Read the SEC filing and the company transcript yourself before you act.
