## Automaticall

Automaticall turns every missed call into a handled conversation. When nobody on your team can pick up, the AI assistant answers instantly with a human-like voice, works through the caller's questions, qualifies the lead and, where relevant, places a booking directly into your Google, Outlook or Apple calendar with respect for your lunch breaks and meeting-free blocks. You train the assistant on what to say, what to ask and how to behave, so it reflects the tone of your business.

A distinctive part of the product is its spam defence: instead of simply declining nuisance calls, the assistant keeps suspected telemarketers and scammers talking until they give up, which reduces repeat calls. After each conversation you receive a summary and clear action items, and follow-up details can be sent to email or WhatsApp so nothing is lost between channels. The service also offers embeddable website widgets that let visitors start a call or request a callback and convert into qualified leads.

Setup is deliberately lightweight: choose a personality and script in a short guided flow, connect a calendar, then activate with a QR code and a local number. Automaticall supports demo numbers in the United States, United Kingdom, Canada, Germany, Czech Republic and the Netherlands, and the assistant handles more than 25 languages with native-trained voices, with the option to bring your own voice.

**Pricing & Plans:** Free trial with no credit card required; paid plans start at $9.99/month and include 50 call minutes, with additional minutes purchasable in bulk. Custom/partner pricing available on request.

- **24/7 missed-call answering:** Every unanswered call is picked up instantly by an AI assistant with a natural-sounding voice, including nights, weekends and holidays.
- **Calendar-aware appointment booking:** Checks availability and books meetings directly in Google, Outlook or Apple calendars, respecting lunch breaks and meeting-free time.
- **Active spam and scam filtering:** Detects telemarketers and scammers, keeps them engaged until they give up, and reports on the calls it deflected.
- **Post-call summaries and follow-ups:** Delivers a call summary with action items, and sends details by email or WhatsApp so nothing falls through the cracks.
- **Multilingual voice and website widgets:** Handles 25+ languages with native-trained voices and offers embeddable widgets that turn site visitors into qualified leads.

**Strengths:** Answers missed calls instantly, 24/7, without extra staff; Spam-trapping behaviour measurably reduces nuisance call traffic; Calendar and WhatsApp/email integrations keep bookings and follow-ups in one flow; Straightforward setup with QR-code activation and demo numbers in several countries

**Limitations:** Call minutes are metered, so heavy call volume requires buying extra minutes; Advanced configuration and voice cloning involve contacting the team; Effectiveness depends on how well you train the assistant's script and intents

## Sierra

Sierra is a conversational AI platform aimed at businesses that want to improve customer experience and grow customer lifetime value. Instead of static chatbots, Sierra focuses on AI agents that can hold natural conversations, take actions through connected systems, and adapt over time. The company describes its offering as the leading conversational AI platform for businesses, used by large brand-name enterprises across sectors such as financial services, healthcare, telecom, media, travel and hospitality, retail, technology, and the public sector.

A central feature is Ghostwriter, an agent-building agent that can take unstructured input — standard operating procedures, transcripts, whiteboard photos, or audio recordings — or a plain-English goal, and turn it into a production-ready, multilingual, multichannel agent with built-in guardrails. Around it sits a set of operating tools: Insights Explorer for deep, research-style analysis of agent performance, Monitors that flag conversations needing attention, Experiments for multivariate testing of conversation design, and Observability that exposes tool calls, knowledge lookups, and latency. Horizon adds long-horizon planning, customer context memory, outcome optimization, and proactive engagement triggered by real-world signals.

Sierra deploys a single agent across chat, SMS, WhatsApp, email, voice, and ChatGPT, so customers get consistent help on the channel they prefer. Trust, security, and compliance are emphasized, including a public Trust Center. Notably, Sierra prices on outcomes rather than seats: the company states customers pay for a job well done, aligning cost with the value the agent delivers.

**Pricing & Plans:** Outcome-based pricing: Sierra states that customers pay for results delivered rather than per seat. Specific rates are not published and require contacting Sierra.

- **Ghostwriter agent builder:** Turn SOPs, transcripts, whiteboard photos, audio recordings, or a plain-English goal into a production-ready, multilingual, multichannel agent with built-in guardrails.
- **Omnichannel deployment:** Run a single agent across chat, SMS, WhatsApp, email, voice, and ChatGPT so customers get consistent help on their preferred channel.
- **Analytics and observability:** Insights Explorer, Monitors, Experiments, and Observability surface agent performance, flagged conversations, and every tool call, lookup, and latency event.
- **Horizon long-horizon planning:** Breaks complex outcomes into steps that improve over days or months, with customer context memory and proactive engagement triggered by real-world signals.
- **Outcome-based pricing:** Pay only for the value Sierra delivers, aligning cost with completed customer outcomes instead of seats or licenses.

**Strengths:** Ghostwriter builds production-ready agents from SOPs or plain-English goals, lowering the barrier to launching.; Single agent spans chat, SMS, WhatsApp, email, voice, and ChatGPT for consistent cross-channel support.; Outcome-based pricing ties cost to delivered results rather than seats.; Strong operational tooling for analytics, experiments, and observability of live agents.

**Limitations:** No published price list, so budgeting requires a sales conversation.; Enterprise-oriented positioning may be heavy for very small businesses.; Deep capabilities like Horizon and Context Engine assume integration with existing systems to reach full value.
