Buying Guide

Workflow Fit

Start with tools that clearly map to knowledge & documents workflows instead of generic assistants. The winner should remove a full step from the job, not just autocomplete text.

Buying Guide

Grounding Quality

For retrieval-heavy stacks, ingestion quality, chunking, citations, and filtering matter more than raw model branding. Weak grounding will poison downstream outputs.

Buying Guide

Integration Surface

Check whether the tool plugs into the systems you already use. For this group, the biggest gains usually come from context sharing, handoffs, and automation coverage.

Buying Guide

Pricing Model

Watch for usage-based pricing, seat minimums, and enterprise gating. Cheap entry plans matter less than predictable cost once the workflow becomes part of the stack.
