There isn’t a universal winner—decide by fit. Check: (1) Workflow/UI alignment; (2) Total cost at your usage (seats, limits, add‑ons); (3) Integration coverage and API quality; (4) Data handling and compliance. Use the table above to align these with your priorities.
Explore adjacent options in the Conversational AI category. Shortlist by feature depth, integration maturity, transparent pricing, migration ease (export/API), security posture (e.g., SOC 2/ISO 27001), and roadmap velocity. Prefer tools proven in production in stacks similar to yours and with clear SLAs/support.
Checklist: (1) Must‑have vs nice‑to‑have features; (2) Cost at your scale (limits, overages, seats); (3) Integrations and API quality; (4) Privacy & compliance (GDPR/DSA, retention, residency); (5) Reliability/performance (SLA, throughput, rate limits); (6) Admin, audit, SSO; (7) Support and roadmap. Validate with a fast pilot on your real workloads.
Normalize to your usage. Model seats, limits, overages, add‑ons, and support. Include hidden costs: implementation, training, migration, and potential lock‑in. Prefer transparent metering if predictability matters.
Run a structured pilot: (1) Replicate a real workflow; (2) Measure quality and latency; (3) Verify integrations, API limits, error handling; (4) Review security, PII handling, compliance, and data residency; (5) Confirm SLA, support response, and roadmap.
