## Harmony.ai (formerly One AI)

Harmony.ai builds AI voice agents that hold real phone conversations rather than pushing callers through a phone tree. The platform targets go-to-market teams and covers the full lifecycle: qualifying inbound contacts, setting appointments against calendar availability, running discovery calls, following up on dormant pipeline, handling renewals and win-back, and even chasing overdue payments. Agents respond in under 200 milliseconds, navigate existing IVR phone trees to reach the right person, and hand warm prospects to a human rep with a live transfer.

Beyond the agent itself, Harmony bundles the operational pieces that voice deployments usually require: a predictive, power and batch AI dialer, smart routing and IVR traversal, branded caller ID, call analytics with automatic QA scoring, and a visual canvas for building and editing agent behaviour. Every call is recorded, transcribed and fed back into an optimisation loop, where insights surface common objections and drop-off points and changes are A/B tested against past calls before rollout. Industry templates ship with pre-trained vocabulary and compliance baselines for healthcare, finance, real estate, insurance, hospitality and automotive.

The company reports SOC 2 Type II, GDPR, HIPAA and ISO 27001 compliance, and states that agents would disclose they are AI by default, with configurable disclosure rules by region. It positions itself against developer toolkits such as Bland, Retell and Vapi by offering a managed revenue-calling system rather than a stack to assemble. Note this is a third-party entry: OpenAITools is not affiliated with Harmony.ai or monday.com.

**Pricing & Plans:** Harmony.ai offers a free trial sign-up and books demos through sales; specific plan prices are not published on the public site, so teams should request a quote based on call volume and seats.

- **Sub-200ms voice agents:** Purpose-trained phone models deliver natural interruptions, tone and timing, with responses grounded in your data to reduce pauses and hallucinations.
- **AI dialer and smart routing:** Predictive, power and batch dialing for outbound volume, plus inbound intent detection and IVR traversal to reach the right stakeholder.
- **Full lifecycle call playbooks:** Prebuilt flows for lead qualification, appointment setting, discovery, follow-ups, renewals, upsell and payment reminders, built on your existing scripts.
- **Call analytics and auto-QA:** Every conversation is recorded, scored and exportable, surfacing objections and drop-off points with A/B tests validating changes before rollout.
- **CRM and telephony integration:** Runs on your existing telephony and writes dispositions, transcripts and booked meetings back to your CRM records automatically.

**Strengths:** Sub-200ms response times with a model trained specifically for phone conversations; One managed platform covers dialer, routing, analytics and CRM write-back instead of a DIY stack; Industry compliance baselines and certifications for regulated verticals; Self-improving loop that optimises agent behaviour against recorded historical calls

**Limitations:** No public price list, so costs require a sales conversation; Advanced tuning is oriented to revenue teams rather than developers wanting raw API control; Disclosure rules and consent configuration still require your own legal review by region

## Switch

Switchphone, listed in this directory as Switch, is positioned as an always-on receptionist for small and mid-sized service businesses. The core promise is simple: when a customer calls and nobody is free to pick up, the AI voice agent answers in under two seconds, asks what the caller needs, and takes the next useful action rather than routing them to voicemail. It books appointments against live calendar availability, qualifies leads with scripted questions, and hands high-value callers to a human — all with a transcript and summary written back to your records.

The product also covers outbound work. A follow-up agent chases missed enquiries, sends reminders, and re-engages customers who have gone quiet, which is how the vendor frames the payback story: one recovered call per month is often enough to cover the subscription. Setup is deliberately low-friction — you enter your website URL, receive a text code, and call to hear a receptionist built from your own content before committing.

The site reports 30,265+ verified App Store reviews and says the product has been trusted since 2021. Published tiers are Starter, Standard, and Pro, billed monthly with minute allowances and a 20% discount for annual billing. Switchphone is operated by Atlas Guide, Inc. and is aimed at trades, salons, clinics, agencies, and other businesses that live and die by the phone.

**Pricing & Plans:** Paid monthly subscription with three published tiers: Starter at $297/month (up to 1,000 minutes), Standard at $497/month (up to 1,650 minutes), and Pro at $797/month (up to 2,650 minutes), with 20% off on annual billing. Building and testing a preview receptionist is free; you only pay once it goes live on your number, and there is a 30-day money-back guarantee.

- **Instant 24/7 call answering:** The agent picks up in under two seconds, 24/7, and can handle unlimited concurrent calls without hold times or voicemail.
- **Live appointment booking:** It checks real calendar availability, books the slot during the call, logs the customer to your CRM, and texts a confirmation before hanging up.
- **Lead qualification and call transfer:** Ask qualifying questions, flag high-value callers, and hand them to a human while routine calls never interrupt your staff.
- **Outbound follow-up and reminders:** An outbound agent follows up on missed enquiries, sends reminders, and re-engages lapsed customers on your schedule.
- **Transcripts, summaries and dashboard:** Every call is recorded and summarised, with a live dashboard showing answered calls, bookings, and outcomes.

**Strengths:** Answers calls in under two seconds around the clock with unlimited concurrent lines; Books appointments and writes results straight into your calendar and CRM; Separates routine calls from high-value leads so staff are only interrupted when it matters; Free preview build means you hear the agent on your own business before paying

**Limitations:** No self-serve public sign-up flow — you must call the AI agent or request a demo to get a plan; Plans are priced per month with minute caps (1,000–2,650 min), so high-volume callers need to upgrade; Built for phone-based businesses; teams without inbound call volume will see little value
