AI Fact-Check Writing Assistant

Automatically review your notes while writing and flag factual errors or misleading statements

Problem

Bloggers, students, and writers often introduce factual errors or outdated information due to memory bias, and proofreading afterward is time-consuming. Most AI writing tools focus on generation rather than fact-checking against the user's own notes. Someone is building Threadz, a 'human-first' AI writing app whose core feature is letting AI review notes for factual errors—validating this need.

Solution

A writing assistant that lets users import their notes/drafts, then uses AI to check factual statements sentence by sentence, highlight dubious content, and suggest corrections or sources. Integrates with common note-taking apps for in-flow checking without interrupting creativity.
