One of the core promises of AI is that the more it knows about you, the better it can help. Delivering on that promise often means an AI app listens to your activity continuously to gather context. Privacy concerns follow, but startups keep building anyway, betting the market for personalized assistance is large enough to absorb those worries.
Former Plaud executive Peter Mo is building Ambi, an app designed to listen in the background and deliver real-time intelligence and insights. The company announced Monday it has raised $26 million across multiple funding rounds.
The rounds were led by Luminous Ventures, which has backed companies like Meituan and Unitree Robotics, along with original design manufacturer (ODM) Huaqin.
How the AI App Listens and Responds
Ambi is releasing apps for iPhones, Macs, and Apple Watch. These apps act like meeting notetakers, but users can choose to have them listen so they capture context all day.
Meeting notetaking companies have focused on automating tasks after calls end, using summaries, action items, and connectors to software systems. Ambi wants to go further by having its agent start work during the meeting itself.
The company says its AI agent can proactively offer suggestions or surface relevant knowledge while you are in a meeting, based on your calendar, meetings, knowledge base, and web data. Users can also start a task on one device and continue it on another.
“The way we interact with intelligence is limited. Often the intelligence is trapped on the screen, and if you use hardware like Plaud, you need to wait for recording to transfer to the phone, upload to the cloud, and get intelligence after processing. That’s why we are building Ambi to use AI anytime and anywhere,” Mo, the company’s co-founder and CEO, said.
Why Real-Time Context Matters
Most notetakers summarize what already happened. Ambi’s pitch is different: the agent works while the conversation is still unfolding. That shift matters for anyone who wants help recalling a detail, drafting a response, or pulling up a document mid-meeting.
The trade-off is that the AI app listens continuously to make this possible, which puts context collection at the center of the product rather than at the edges.
Ambitions Beyond the Phone
Ambi has ambitions to capture more information. Its upcoming desktop app will be able to look at the work users do and store important parts in its memory to give more personalized suggestions. Apps like Littlebird or Minimi already do something similar.
The startup also plans to launch its own hardware device, which will have a screen, a speaker, a camera, and microphones to capture context and display information.
That combination suggests Ambi wants to move from a phone-based assistant to an always-available companion across devices and rooms. Hardware would let the company control the full experience, from capture to display.
The Privacy Question
Ambi’s launch comes amid growing concerns around AI devices that lack enough indicators to show they are capturing data on people nearby. It is not clear if Ambi’s apps or its upcoming device will have enough indicators to alert third parties that their conversations are being recorded if the user doesn’t disclose their use of Ambi’s tech.
Some meeting notetakers have even been sued because their tech recorded people’s conversations and data without their consent. The recent release of Apple’s Audio Intelligence feature, which transcribes speech continuously, has also raised privacy concerns.
Mo said users can turn off ambient data capture on Ambi’s apps and devices at any time, and the feature is off by default. The startup said it doesn’t store any recordings of users and encrypts the data, but it didn’t specify what kind of encryption it uses.
Despite these measures, the onus of declaring ambient capture is still on the users. Mo classified this as an industry-wide problem.
“We have to inform our users that they have to tell others about ambient capture. We, as an industry, haven’t solved this problem [of disclosure]. We have tried to put the information about disclosure in every place possible, but if users try to hide the capture, we can’t just solve the problem,” he said.
What Users Should Consider
Anyone using an AI app listens feature should think about the people around them, not just their own convenience. Disclosure remains a user responsibility, and consent rules vary by location and situation. Turning capture off by default helps, but it does not remove the need for clear communication.
Team and Hiring Plans
Ambi currently has over 50 staff across offices in San Francisco, Beijing, Shanghai, and Shenzhen.
The company is hiring for its go-to-market function and AI engineers to work on speech-recognition models. The go-to-market roles suggest Ambi is preparing to push beyond an early-adopter audience, while the speech-recognition hires point to investment in the core technology that makes an AI app listens useful in noisy, real-world settings.

What to Watch
Ambi sits at the center of two converging trends: AI agents that want constant context and rising scrutiny over always-on recording. The company’s bet is that proactive, cross-device assistance will outweigh disclosure concerns.
For now, the $26 million gives Ambi room to ship its apps, build its desktop tool, and develop hardware. The bigger question is whether an AI app listens approach can win trust at the same time it scales.
