Word Auto-Index Generator: SKIP, 42/100 | Ideas Lab

An automated table of contents generator for Word documents solving a minor formatting pain point in a mature, declining market.

The pain

Users spend time manually creating and updating tables of contents and indexes in Word documents, especially for long-form content.

The gap

Word already has built-in TOC/index features that are free and functional, though not perfectly intuitive. The gap is small and closing.

Build angle

If pursuing: Position as AI-powered intelligent indexing that understands document semantics, auto-tags sections, and generates contextual indexes, not just automated formatting.

Strengths

Real, documented pain point (Google Trends validation)
Clear use case in academic/professional writing
Low technical barrier to MVP
Potential B2B angle (enterprise document management)

Risks

Microsoft Word already solves this natively, switching costs are high
Tiny TAM: only power users of long documents care enough to pay
No defensible moat, easily replicated or integrated by competitors
Declining relevance: Google Docs, Notion, and AI writing tools are eating Word's lunch
Low willingness to pay: users expect this as free functionality
Saturated market: multiple free/cheap solutions exist (Grammarly, Hemingway, etc.)

Fly Labs Method

Is the pain real, is there a gap, is it the right time, can one person build it.
