As answered by people managing PremiumGuardHQ and Diffyn.
PremiumGuardHQ's answer
PremiumGuardHQ is built specifically for the wheel options strategy, not generic trade journaling. Connect your brokerage account and it automatically detects complete wheel cycles from your actual fills (cash-secured put, assignment, covered calls, called away) with no manual tagging or trade-by-trade data entry. It then reconciles cost basis, separates premium P&L from equity P&L, and computes how much income you can safely withdraw without eroding your capital base. That last question is the one no journal or spreadsheet answers.
Diffyn's answer:
Addresses workflow and change management on LLM prompts, provide teams with traceability and visualization of tests across multiple models, provide deeper understading into efficiency of these prompts.
PremiumGuardHQ's answer
Most alternatives are journals: you type in or tag every trade yourself, and the analysis breaks the moment you fall behind. PremiumGuardHQ syncs directly with your broker so your books stay current whether you remember to update them or not. It also answers questions that matter specifically to wheel traders: real premium yield, equity P&L net of assignments, capital at risk by position, and a safe withdrawal number. After every sync your whole account is reviewed, and risk, strategy drift, and track-record patterns surface as graded insights. There is a free plan, and Pro comes with a 14-day trial with no credit card required.

PremiumGuardHQ's answer
Self-directed options traders running the wheel strategy who treat premiums as a real income source, ranging from people supplementing a salary to people funding their lifestyle from their portfolio. They typically trade at Schwab, Interactive Brokers, Robinhood, or Fidelity, and they care about two questions: am I actually making money after assignments, and how much can I withdraw without shrinking my base.
Diffyn's answer:
Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.
PremiumGuardHQ's answer
Founder Michael O'Donnell is a lifelong entrepreneur who sold his previous company, Cave Tools (barbecue tools e-commerce), in 2021 and began trading the wheel with his own capital. He was originally taught to withdraw premiums immediately as income. That worked until a downturn assigned him stock below cost basis and he realized he was quietly eroding his equity base, while broker cost-basis adjustments made the displayed numbers untrustworthy. He built an internal tool to answer three questions: what's my real premium yield, what's my equity P&L net of assignments, and how much is safely withdrawable. Conversations with other wheel traders surfaced the same gap, so the internal tool became PremiumGuardHQ.
Diffyn's answer:
I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.
PremiumGuardHQ's answer
