## Gnbly

Gnbly positions itself as a research-led studio rather than a single-purpose SaaS. Three focused products share one underlying agent platform: long-horizon memory that carries context across days and tools, deterministic tool-use with retries and replay, per-tenant isolation with audit logs, and open tracing so a human can inspect, intervene or take over any step. Because the runtime is model-agnostic, swapping the underlying LLM does not require rebuilding the products. Internal metrics the studio publishes include 12 million-plus agent actions per month across 40-plus countries and a trailing-90-day uptime of 99.98%.

NatterGPT is the product closest to the original call-handling brief. Its agents pair a templated script with a chosen voice and model, then place outbound calls to a list, answer inbound numbers 24/7, or run in copilot mode where a human speaks and the agent feeds one-line prompts on screen. It auto-detects and switches language mid-call, records MP4 audio with a full transcript on every call, and offers five per-number inbound modes including caller-ID routing that sends VIPs to a different agent. Published plans are Hobby at $49/month for 120 minutes, Pro at $200/month for 10 hours with recording, and Business at $2,000/month for 100 hours with inbound calling and reports. Vidsue covers script-to-screen video production, and WorkerFleet orchestrates specialised research, ops, support and sales agents with connectors for Slack, Notion, HubSpot and Linear.

Compliance posture is stated in plain terms: SOC 2 Type II, GDPR alignment, HIPAA-ready configurations, region pinning and customer-managed encryption. The studio is upfront that calls traverse third-party carriers, speech-to-text, text-to-speech and LLM providers, so sensitive information should be handled with that chain in mind. Numbers are currently provisioned by Gnbly for US local and toll-free use, with bring-your-own-carrier on the roadmap.

**Pricing & Plans:** Paid, sold per product. NatterGPT voice agents publish Hobby at $49/month for 120 minutes, Pro at $200/month for 10 hours with call recording, and Business at $2,000/month for 100 hours plus inbound calling and reports. A 14-day trial with no credit card runs on every plan. Vidsue and WorkerFleet are priced separately.

- **AI voice agents for outbound and inbound:** Templated scripts pair with a chosen voice and LLM to dial a contact list or answer inbound numbers around the clock, with transcription and outcomes logged per call.
- **Automatic multilingual switching:** Agents mirror the caller's language across 99 supported languages, switching mid-call without any language selector or per-call configuration.
- **Copilot mode for risky calls:** A human stays on the line while the agent listens to the live transcript and writes one short sentence at a time on screen to be read aloud.
- **Five per-number inbound modes:** Route each number to a full AI agent, a browser softphone, copilot assist, forwarding to a cell, or rejection, with caller-ID rules sending VIPs elsewhere.
- **Shared agent platform:** Long-horizon memory, replayable tool-use, audit logs, tenant isolation and full tracing are shared across NatterGPT, Vidsue and WorkerFleet.

**Strengths:** One agent runtime underpins every product, so memory and tooling carry across use cases; NatterGPT speaks 99 languages and switches automatically mid-call; Copilot mode gives a safer middle ground than fully autonomous agents; Published per-product pricing with a 14-day card-free trial

**Limitations:** Pricing is aimed at teams, with the $2,000/month Business tier far above casual use; Voice quality and turnaround depend on third-party carriers, STT, TTS and LLM providers; Bring-your-own carrier is still on the roadmap, so numbers are provisioned through Gnbly today
