This month CallSwitch One Pro gains AI Transcription & Summaries. The launch covers both an initial release and a second phase, and it’s the first of several AI capabilities we’re rolling out through 2026. Here’s what it does, how it’s built, and what follows it on the roadmap.
The feature runs on Nebula’s AI infrastructure, which is 100% self-hosted in UK-based Google Cloud Platform data-centres using open-source LLMs. Call audio is processed on infrastructure we control rather than sent to a third-party AI provider, and customer data is never used to train a model. That means transcription operates with full UK data sovereignty.
Because we host the infrastructure ourselves, there’s no per-minute metering. Transcription is included with CallSwitch One Pro at no added cost. It’s part of the existing subscription rather than a usage-based add-on, so there’s no separate bill and no consumption to track, and users can enjoy inclusive usage immediately.
“Hosting the models ourselves, in UK data-centres, is what lets us offer transcription with genuine data sovereignty rather than a privacy policy that points elsewhere. It also means we can include it in CallSwitch One Pro at no extra cost, because we’re not paying a hyper-scaler by the minute.” Howard Stevens, CEO, Nebula
Transcriptions are accessed from the dashboard. Each one comes with a bullet-pointed summary and a copy-to-clipboard tool. Transcripts are keyword-searchable, with separate agent and caller channels and time-stamping throughout.
Transcripts can be downloaded as WebVTT files with time-stamping preserved. There’s also an inbuilt feedback tool for reporting on accuracy and flagging what to improve.
The release also includes granular settings to apply transcription to specific users or call routes, automatic email delivery of call summaries with a call recording download link, and CRM integrations for delivering captured outputs (rolling out over a six-to-eight-week window).
All of this is included with CallSwitch One Pro at no additional cost.
“This first release covers the core workflow, including searchable, time-stamped transcripts with summaries and the ability to send these directly to email or CRM integrations. But we've built it as a foundation rather than a finished product. The architecture is designed to extend, so the features that follow plug into the same framework rather than requiring us to rebuild.” James Lockhart, Head of Product, Nebula
Next month we’ll be aiming to launch our Call Actions tool, also inclusive with CallSwitch One Pro.
This adds dashboard-based post-call actions with owner and due-date capture, available to copy or download to CSV, alongside several integrated Next Steps options such as Add to Calendar and Draft Email. As functionality is rolled out, we’ll also add these to the automatic emails and CRM integrations that we’re deploying this month.
In August, an AI Assistant Add-On follows. This delivers transcription, summaries and actions directly to desktop and mobile applications, offering immediate efficiency gains for all users. This add-on will be chargeable per user, with industry-leading pricing.
AI transcription is becoming a standard expectation. What is less common is being able to tell a customer, without caveat, where their conversations are processed and that they will never become training data for another provider’s model. For partners selling into regulated sectors or to SMEs handling sensitive data, that distinction is often what determines whether AI features can be used at all.
That assurance is possible because Nebula owns and hosts the platform end to end. It’s the same reason the feature can be built on our own timeline, priced without metering, and included with the Pro subscription rather than charged as a separate consumption-based product.
For partners, that means an AI capability they can position on a flat, predictable cost, with no usage to monitor and no separate bill to explain. It also sets the pattern for the AI features that follow: self-hosted, UK-sovereignty assured, and built to extend the platform rather than sit alongside it.
