Filter a small, dated official-source catalog using hard constraints. Unknown or stale evidence cannot satisfy a requirement.
1. Choose hard constraints
This is a deterministic filter, not an AI recommendation or ranking. The catalog covers three conventional desktop workflows. Each required claim must be supported by the cited official sources and within its review window. Unknown does not mean unsafe or unavailable; it means this catalog cannot establish the requirement.
Budget refers to software license cost, not your computer, connectivity or time.
2. Verified matches
Matching waits for a current browser date. The dated catalog below is available without JavaScript.
Comparison and automatic extraction have no verified catalog match. The local comparison lab records outputs you supply; the manual action-item editor records your interpretations. Neither calls a model or performs automatic extraction.
3. Catalog, sources and limits
Official pages checked on 16 October 2026. These are documentation checks, not hands-on product tests. The 30-day review window is our editorial rule, not a vendor guarantee: after 15 November 2026 entries are excluded until rechecked. No date refresh happens automatically. Filtering uses your browser’s UTC date; verify your clock.
