Gabriel’s notes
EVI is the first voice AI that really sounds like it understands you. By adapting its tone of voice, it emulates the way humans convey meaning beyond words, unlocking more efficient, smooth, and satisfying AI interactions.
Good fit if you want to:
- build, test, or ship software faster (APIs, dev tooling, code assistance).
Pricing snapshot (auto-enriched): Free tier available with 5 minutes of EVI usage; pricing is usage-based with plans ranging from $3 to $500 per month including varying amounts of EVI minutes and additional usage charged per minute; no per seat pricing but team seats available on higher plans.
