A company called Equal AI has raised $30 million to build an AI assistant that answers your spam calls for you. Instead of blocking unwanted calls outright, the AI picks up and talks to the caller, then tells you what the call was about — so you can decide whether you want to take it, TechCrunch reports.

This matters because India has a massive problem with unwanted calls. Over a billion people have mobile phones there, and they are bombarded with spam, scams, and sales pitches every day. The government tried to fix this with a "Do Not Call" registry — basically a list of people who said they did not want to receive unsolicited calls — but it has not worked very well. Equal AI thinks AI can do better.

Other companies already screen calls. Google has a feature called Call Screen that comes on Pixel phones, and it can block spam automatically. There is also a Swedish app called Truecaller, which is hugely popular in India. It uses a crowdsourced database of spam numbers plus machine learning to identify scam calls. But Equal AI is trying something different: instead of just saying "this is spam, block it", their AI actually talks to the caller. It listens to what they say, understands what they want, and summarizes it for you.

That sounds simple, but it is technically complicated. A normal spam blocker just checks the caller ID before the phone even rings. Equal AI's AI has to listen, understand, and respond in real time, all within a few seconds. It also has to work across India's patchy phone networks — 4G coverage is congested in many places, and 5G is only available in big cities.

One reason Equal AI can afford to do this now is cost. A few years ago, it would have been too expensive to route every incoming call through an AI conversation. But speech recognition and AI language models have become much cheaper and faster. Meta and OpenAI have released free, open-source versions of their AI tools, which brought prices down dramatically. Suddenly, this kind of service became possible.

There is a downside worth thinking about. The AI system listens to every call you get — it knows who is calling, what they want, and how urgent it sounds. That is a lot of personal information in one place. The question of how Equal AI will handle that data, whether it will sell it to advertisers, and how it will keep it private is going to matter a lot — especially in India, which has strict new laws about data privacy that came into effect in 2023.

Equal AI also faces an uphill battle against bigger competitors. Truecaller has already been installed on hundreds of millions of phones in India and has deals with phone carriers. Google owns Android, the operating system that most phones in India run, which gives it advantages that a smaller app company cannot match. Equal AI needs to prove that its conversational AI is so much better than what Google and Truecaller offer that people will choose it and stick with it.

The $30 million gives Equal AI a few years to make its case. India is so large that even a small slice of the market would be worth a fortune. The real test ahead is whether the AI gets good enough to become indispensable, or whether Google and Truecaller simply add similar features to their own products.
