Quick Overview: Two Different Approaches

Air AI

Air AI positioned itself as one of the first conversational AI platforms capable of conducting full-length phone calls lasting 10 to 40 minutes. The platform promised human-like interactions with context awareness and memory across extended conversations.

Key promises included:

• Natural-sounding voice synthesis with turn-taking
• Integration with 5,000+ applications including Salesforce and HubSpot
• SOC 2 Type II certification and HIPAA compliance capabilities
• 12 standard voice personalities with customization options

However, there are significant concerns about platform status. Multiple sources report that as of 2025, Air AI's platform has experienced operational issues, with some core features reportedly inactive. The agency program and outbound voice functionality have faced disruptions, and users have reported difficulty reaching support.

Burki

Burki is a production-ready voice AI platform focused on ultra-low latency (0.8-1.2 second response times), transparent pricing, and maximum deployment flexibility. The platform emphasizes developer control with BYO (Bring Your Own) API keys and multi-provider support.

Key differentiators include:

• Sub-second response times with optimized pipeline architecture
• $0.03/min platform fee with BYO mode options
• 50+ provider integrations across LLM, TTS, and STT
• Included HIPAA compliance with free BAA
• Unique IVR Explorer feature for legacy system migration

Pricing Deep Dive

Air AI Pricing Structure

Air AI's pricing has been a significant barrier to entry for many businesses:

Upfront Licensing Fee: $25,000 to $100,000 depending on business size and use case. This is required before accessing the platform.

Per-Minute Usage:

• Outbound campaigns: $0.11/minute
• Inbound/API calls: $0.32/minute
• Additional Twilio telephony costs: $0.0075-$0.015/minute

Critical Billing Detail: Air AI charges for entire call duration including ring time and connection time, not just when the AI is speaking. A 4-minute conversation that took 30 seconds to connect bills as 4.5 minutes.

Additional Costs:

• Premium CRM integrations may incur extra fees
• Extended training or setup support
• Custom voice development for enterprise

Burki Pricing Structure

Burki uses a transparent, usage-based model with no upfront costs:

Platform Fee: $0.03/minute flat rate

Provider Costs: Pass-through pricing for LLM, TTS, STT, and telephony with full transparency

BYO Mode: Use your own API keys and pay providers directly, eliminating markup

Free Trial: 200 minutes plus a free phone number for 30 days, no credit card required

Cost Comparison Example

For a business making 10,000 outbound minutes per month:

Air AI:

• Upfront license: $25,000-$100,000 (one-time or annual)
• Monthly usage: 10,000 x $0.11 = $1,100
• Twilio costs: ~$100
• Total first month: $26,200-$101,200
• Ongoing monthly: ~$1,200

Burki:

• Upfront: $0
• Platform fee: 10,000 x $0.03 = $300
• Provider pass-through: ~$400-600 (varies by configuration)
• Total monthly: $700-$900

Annual savings with Burki: $3,600-$6,000 in platform fees alone, plus avoiding the massive upfront investment.

FAQ

Is Burki a good Air AI alternative?

Yes. Burki offers similar conversational AI capabilities with several advantages: no upfront licensing fees, lower per-minute rates, transparent billing, BYO API key support, and an actively maintained platform. The 200-minute free trial lets you evaluate the platform without financial commitment.

Can I migrate from Air AI to Burki?

Burki's assistant configuration supports similar use cases. Migration involves recreating your conversation flows and prompts in Burki's system. The voice builder assistant simplifies this process, and Burki's free trial provides time to test before committing.

Which platform has better voice quality?

Voice quality depends on your chosen TTS provider. Burki supports 8+ TTS providers including ElevenLabs, Deepgram, Cartesia, and OpenAI, giving you flexibility to select voices that match your brand. Both platforms can achieve high-quality voice synthesis with proper configuration.

Is Air AI still operational?

As of January 2026, there are mixed reports about Air AI's operational status. Some sources indicate platform disruptions and inactive features. We recommend verifying current status directly with Air AI before making purchasing decisions.

Which is better for healthcare?

Burki includes HIPAA compliance at no extra charge with a free Business Associate Agreement (BAA). The platform also features automatic PII redaction for transcripts and memories. Air AI advertised HIPAA compliance, but given reported platform issues, we recommend confirming current compliance status directly.

What if I need 40-minute conversations?

Burki supports configurable maximum call lengths per assistant. While Air AI specifically marketed long-duration calls, Burki's conversation continuity feature maintains context across multiple interactions, which can be more practical for complex customer journeys.

The Bottom Line

Air AI attempted to pioneer the long-form conversational AI space with ambitious technology, but high barriers to entry (starting at $25,000) and reported platform stability issues have created challenges for many potential users.

Burki offers a pragmatic alternative: no upfront costs, transparent per-minute pricing starting at $0.03, extensive provider flexibility, and an actively maintained platform. The 200-minute free trial with no credit card requirement lets you evaluate the platform thoroughly before any commitment.

For businesses seeking a reliable Air AI alternative with lower costs, greater control, and proven operational stability, Burki represents the logical choice. The ability to bring your own API keys, choose from multiple telephony providers, and leverage unique features like IVR Explorer provides flexibility that enterprise-priced alternatives simply cannot match.

Start with Burki's free trial, build something real, and make an informed decision based on actual experience rather than marketing promises.
