What we know about Upfirst
Upfirst is a voice ai platform: per-call-bundle AI receptionist with 35+ languages and declining overage rates up to 600 calls/mo. This profile tracks every Upfirst fact we have verified, each linked to a primary source and dated.
On pricing, Upfirst starts at $24.95 per month for its entry tier. That is the sticker rate: real production cost usually runs higher once you add a language model, a voice provider, and telephony minutes.
New Upfirst accounts get 14-day free trial, all features to test with before a card is required, which is enough to run a handful of real calls and judge latency and voice quality for your own script rather than a demo.
On capabilities, Upfirst covers built-in knowledge base, buy/port numbers in-platform, and self-serve signup, and does not offer annual contract required for best pricing?. Each of those is verified against Upfirst's own docs or dashboard, not marketing copy.
For compliance, with Upfirst: HIPAA is enterprise_only on the plans we checked. If you are in a regulated space, confirm the current posture with Upfirst before you commit, since these change plan by plan.
Upfirst ranks the 14th-widest language coverage of the 31 voice ai tools we track, so where it lands for you depends on which of those matters more.
