Self-description (latest meta description): “Sierra helps businesses build better, more human customer experiences with AI.”
Current plans (latest pricing snapshot)
Snapshot #2971 captured 2026-09-01 via wayback. Raw price language is preserved; the normalized column is filled only when the arithmetic is defensible.
Price history
Normalized monthly USD per plan across pricing snapshots (only plans that could be normalized). Gaps are unobserved quarters, not zero prices.
Feature claims over time
Presence of each lexicon feature on the pricing page at each snapshot (1 = pattern matched). Flicker (present → absent → present) usually signals page A/B variants or extraction noise and is flagged in events.
