Gnbly
A three-product AI studio built for teams that need work finished, not chat
Intermediate
What is Gnbly?
Gnbly is an AI studio behind three products on one agent runtime: NatterGPT for automated phone calls, bookings and IVRs, Vidsue for script-to-video production, and WorkerFleet for orchestrating specialized AI workers with shared memory and full tracing.
Gnbly Inc. is a research-led studio, founded in 2023 and headquartered in San Francisco, that builds AI-native software for go-to-market, content and operations teams. Rather than shipping a single assistant, the company runs three products on one shared agent runtime: NatterGPT for outbound and inbound phone calls, Vidsue for turning scripts and research into produced long-form video, and WorkerFleet for orchestrating fleets of specialized AI workers across research, ops, support and sales. The pitch is narrow and concrete: automate the work behind the work, and judge every product on whether it actually finished the job. The product most relevant to call handling is NatterGPT, a voice agent that dials suppliers, books appointments, works through IVR menus and reports back with a transcript and an outcome. Gnbly describes human-grade timing and turn-taking, multi-step goals that stretch across calls, email and calendars, and a recorded, transcribed and auditable trail for every conversation. Underneath all three tools sits the same runtime, which the company markets on long-horizon memory (context held across days and tools rather than a single chat session), typed and deterministic tool use with retries and replay, per-tenant keys with audit logs, and step-by-step tracing that lets a person inspect, intervene or take over in one click. Practically, the suite suits teams already running a lot of repetitive coordination: a sales or ops group that spends hours on follow-up calls and scheduling, or a content team that needs a steady output of video without a production pipeline. WorkerFleet is the orchestration layer for that work, with drag-and-drop agent workflows and connectors for Slack, Notion, HubSpot and Linear. The shared memory across products means an outcome captured on a call can inform the next task, which is the main argument for buying the bundle instead of point tools. The fit is narrower than a general assistant. Gnbly publishes no per-seat pricing on its homepage, no public free tier and no self-serve signup flow; the visible paths are exploring the products, applying as a design partner, or contacting the team directly. Buyers comparing it to standalone dialers or video generators should expect a sales conversation and an evaluation period rather than a credit card checkout, and should confirm regional availability, contract terms and any model or data residency requirements before committing.
How do you use Gnbly?
1Review the three products and pick your entry point
Start on the Gnbly homepage and read the product cards for NatterGPT, Vidsue and WorkerFleet. Decide whether your first job is outbound calls, video production or general agent orchestration.2Request a conversation with the team
Use the contact form or email on the homepage to describe your use case and volume. This is how pricing, access and any design-partner terms get established.3Apply as a design partner if you want early access
The homepage points design-partner inquiries to the same contact route. Expect a closer working relationship with the product team in exchange for earlier, less finished software.4Configure a call goal in NatterGPT
Once provisioned, define the objective for the agent: who to call, what to book or confirm, and what counts as a completed outcome. Multi-step goals can span calls, email and calendars.5Wire the agents into your stack with WorkerFleet
Connect Slack, Notion, HubSpot or Linear and build drag-and-drop agent workflows so call results flow into records and follow-up tasks without manual copying.6Set approvals and review the traces
Use the observability view to inspect each step, replay runs and require human approval at sensitive points. Decide which actions can run unattended and which need a person.
Pros and cons
Pros
- Call handling is auditable by default: every NatterGPT conversation is recorded, transcribed and reported back with an outcomeAI
- Multi-step goals cross channels, so a call can trigger email follow-ups and calendar bookings instead of ending at the transcriptAI
- Deterministic tool use with retries, replay and approvals makes agent behavior testable rather than probabilisticAI
- Shared runtime across the three products means one security model (SOC 2 Type II, GDPR and HIPAA-ready, region pinning) and common memoryAI
- WorkerFleet ships connectors for Slack, Notion, HubSpot and Linear, so agents can act inside tools teams already useAI
Cons
- No pricing, plans or free tier are published on the homepage, so cost has to be established through a sales conversationAI
- No self-serve signup path is described; onboarding appears to run through design-partner or contact-the-team routesAI
- The three products are separate sites and codebases, and it is unclear whether they can be bought individually or only as a suiteAI
- NatterGPT call quality will vary by telephony region and IVR complexity, and the homepage offers no benchmarks or sample transcripts to checkAI
- Uptime and adoption figures are self-reported vendor metrics without third-party verificationAI
