Show HN: Universal Blindspot Detector (AI meta-analysis)

A free, no-signup tool that reframes AI conversations to surface the smallest moves a user could have made to reveal unknown assumptions, aiming to show the value of AI as a reflective surface for finding "unknown unknowns." The author argues output quality depends on the context behind decisions, and that iterating in planning and strategy phases is cheaper than the execution phase, where they often one-shot output even with local models like Qwen 3.6/3.8. Users must export conversations in specific formats and upload them; the project was built by the author and a few interns in a barn during indie game development and costs money to run.
