Intervo is the open-source platform for creating sophisticated phone call, voice and chat AI agents. Go beyond the limitations of closed platforms like ChatBase and Retell.AI to instantly assist customers qualify leads, handle support and do a whole lot more!
Intervo
Hey everyone,
Manjunath here, one of the makers of Intervo. To be honest, I'm both incredibly excited and terrified to be launching on PH this today. We’ve been living and breathing this project for the last 6 months, so sharing it with you all is a huge moment for us.
So, why another AI tool? Honestly, Intervo started out of pure frustration.
The backstory.
We are the team that built CodeDesign.ai - an AI website builder. We are a small team of 6. We were trying to code, sell, and market... all while handling every single customer question at the same time.
Sometimes leads were going cold overnight because we couldn't respond after 6 PM. Simple questions took hours to answer. It felt like we were letting our customers down, and it sucked.
We looked for a tool, but everything felt. wrong. Either it was a restrictive black box that cost a fortune, or it was just a dumb chatbot that couldn't do anything but point to an FAQ page.
We just wanted an assistant that could actually help. One we could train on our own stuff, that could handle real phone calls, and that we could actually trust to represent us well. We couldn't find it, so we decided to build it. And being developers, we had to make it open-source. We hate being locked in, so we’d never do that to anyone else.
Okay, so what can you actually do with Intervo?
Build an agent without the headache: You literally just write a prompt describing what you want it to do. "You're a friendly assistant for a hotel, your job is to book rooms and answer questions about amenities." Done.
Make it smart with YOUR data: This is my favorite part. Just dump in your PDFs, website links, text files—whatever. It learns your business so it doesn't give dumb, generic answers.
Pick a voice that doesn't sound like a robot: We hooked it up with ElevenLabs and Azure so you can find a voice that fits your brand and actually sounds human.
Deploy as a website widget or as a phone assistant via Twilio. You can do a whole lot with the widget which has AI chat & voice mode. You can also handle incoming and outgoing calls with Twilio.
It's actually open-source: I mean it. Tweak it, connect it to anything with webhooks, host it yourself if you want. No games, no vendor lock-in.
We're a small team, and we need you. We're a couple of people in a Discord server trying to build something cool. (feel free to join us there): https://discord.com/invite/paFJtW8fkZ
When you give feedback, you're talking directly to us, the people writing the code.
We're already working on deeper integrations and smarter agent abilities, but your feedback will decide what we build next. If you have a minute to check it out, we'd be over the moon. Any and all feedback—the good, the bad, the "why on earth didn't you do this?"—is exactly what we need right now.
Thanks so much for your time.
Cheers,
Manjunath
@manjunath_m1 all the best for your launch ✊

Hey everyone, @hakhil_nizeem here.
@manjunath_m1 has shared our origin story. I will just give you a peek through of what's next
Before that, a huge shoutout and thank you to our early customers. We found you on reddit, and you’ve trusted us before we even hit launch, and your real-world feedback has been invaluable in shaping our roadmap.
Our vision is to evolve Intervo from a conversational partner into an autonomous team member that gets things done. Here’s what that will look like in the near future:
Closing the Loop: We’re building deep integrations for your calendar, CRM and much more. Your agent won't just find a lead, it will book the meeting and create the deal in your pipeline, eliminating that painful manual follow-up.
Meeting Customers Everywhere: We're bringing the full Intervo experience voice & chat to WhatsApp. Be instantly available and responsive on the platform over a billion people use every day.
Automating at Scale: For businesses with higher volume, we're developing robust workflows like automated confirmation calls for bookings or appointments. Think of it as intelligent, operational heavy lifting that frees up your team.
These aren't just features; they're the building blocks for our ultimate goal, enabling any business to build and deploy an entire AI workforce.
This launch is the fuel for that future. I'd genuinely love to hear from you in the comments which of these areas would have the biggest impact on your business?
Thanks for helping us build this.
@hakhil_nizeem @manjunath_m1 Nice to see that you will bring WhatsApp integration soon. Do you have any time frame of when that integration will be completed?
Intervo
@hakhil_nizeem @asik_aman Hi Asik! Whatsapp is coming next week. Please join our discord community to keep track of updates!
@hakhil_nizeem @asik_aman @manjunath_m1 Awesome, can't wait to use the whatsapp option. welldone

Congrats with the launch, guys 🎉
Just at the beginning of this year I met a client from a teleco who wanted this tool for his corporation.
As I understood the widgets are not customizable within the Intervo SaaS but I can change their view by myself in case I use opensource?
Intervo
@goshatirov Hey Gosha! That's great. The widget is limited in terms of customization now, but happy to share feedback with my team if you can let us know what kind of customization you'd like to make.
Also, we're introducing an SDK. That should give you full control over the UI to you and the sdk will take care of the rest. Meanwhile, please feel free to test out the open source version as well.
Intervo
@preksha_shah2 Hey Preksha, thank you! We've added a background noise cancellation middleware that should isolate the noises to an extent. Also, we use certain with speech-to-text that also filters out the background noises. we've tested it in office-like noisy environments, we've had good results.
Regarding the internal AI agent for onboarding, this is something which we started with actually. It had too many pieces which we had to build in one go, so we pivoted to conversational AI.
If you're interested, I'd like to know your requirements over a call. Please feel free to leave a message at support(at)intervo.ai. Happy to connect!

With articles like Klarna rolling back AI voice agents because "customers like talking to people". I'm curious on what kind of feedback the Intervo team has received with respect to the AI voice agents used for customer support?
Intervo
@lienchueh That's a fantastic question, and thank you for bringing it up. The Klarna news is super interesting and I wasn't aware of it.
To be honest, I don't believe AI should replace all human interaction, but it should eliminate friction. It's about using the right tool for the job.
For transactional tasks, like processing a refund, checking an order status, or confirming a booking, many customers prefer the speed and 24/7 availability of an AI agent. They just want to get it done, and our goal is to make that instant and effortless.
For complex, emotional, or nuanced issues, nothing beats talking to a person. Our goal is to free up human agents from the repetitive tasks so they can focus on these higher-value conversations where they're needed most.
Also the line between what sounds "AI" and what sounds "human" is blurring fast. The goal isn't to trick anyone, but to make the experience so smooth and natural that it isn't jarring.
Actually, here’s a quick demo of our AI calling a guest to confirm a hotel booking. It shows how a proactive and pleasant AI interaction can work in practice:

Hi Team, Firstly it's a great innovation guys. Keep up the good work. I'm a test engineer for a large furniture retailer based in USA, and we handle thousands of customer inquiries daily. The open-source nature is very appealing for a large-scale deployment. My main question is about multilingual support, (specifically for Spanish, Brazilian Portuguese,Filipino), does the chat/voice synthesis and data ingestion handle different languages? Also, any benchmarks on performance under high concurrency? Looks very promising product.
Intervo
@krishnadas_chandran Hey Krishnadas! Right now, we have support only for English. We just wanted to make it perfect on one language, before we scale to others. This is possible tho, and is on our immediate pipeline. And apart from being open-source, also working on a self-hosting version where we can provide the maintenance and updates while the whole thing runs on-premise.
We don't have any benchmarks yet, but we've optimizing it for performance! Will ask my team to create some benchmarks and see how it fares with the competition.
If you're interested, I'd like to know your requirements over a call. Please feel free to leave a message at support(at)intervo.ai. Happy to connect!
Open-source alternative to Retell.AI? Interesting. But let’s get real—can Intervo actually handle:
1. Real-world chaos: How does your AI handle angry customers or heavy accents? (Most OSS voice agents fail here)
2. CRM sync: Does it auto-log calls to Salesforce/HubSpot without 5 layers of Zapier?
3. Customization: Can I train it on my sales pitch, not just generic scripts?
As someone burned by ‘open-source AI’ that required a PhD to deploy… prove me wrong. #AIDeveloperPTSD
