Hey PH! Co-founder of Cuckoo here 🐦 It’s been a long-time dream to post our launch here, and I’m super excited to finally share what we’ve been working at Cuckoo over the past few months! Gunwoo and I started building Cuckoo in Seoul after seeing firsthand how language remains a significant barrier for global teams—especially during highly technical meetings. Meetings with interpreters are often twice as long, and critical details can get lost in translation especially when they don't understand your product your tech. When bilingual colleagues step in as interpreters, they’re pulled away from their core roles. At Cuckoo, we’re addressing this issue with a real-time AI translator designed specifically for global sales, marketing, and support. Our customers—Snowflake, PagerDuty, Weights & Biases, and ClickHouse—are already using Cuckoo to break down language barriers as they expand globally. We’ve also seen how early-stage AI startups, including our fellow YC batchmates, are going global from Day 1. Here’s how Cuckoo works: (1) Cuckoo works by joining your online meetings as a bot. (It also works in person). (2) You can contextualize translations by uploading relevant documents like pitch decks or product manuals. (3) You can easily share the live transcript with your customers and teammates with a link, allowing them to speak in the languages that they are most comfortable with. Cuckoo also provides you with AI-generated meeting notes, so you can follow up on your conversations in 20+ languages. We have a free trial—give it a try in your next meeting! We’d love your feedback. For those who are constantly involved in these global meetings, feel free to reach out to me personally at yonghee@cuckoo.so and I’d be happy to talk!

Launching soon!

@harryyongheelee The demo looks great! I’ll give it a try and share my feedback. Congrats on the launch—keep up the great work!

@masump First, we use a mixture of large language models and constantly update the phrases as we get the speech data. There's also a part where our users upload their documents (pitch deck, support docs, etc.) and enter keywords (company name, product names, customer names, etc.) to further optimize the translations for their conversations.

Yong Hee Lee

@jaythesong Thanks Jay❣️ Please give it a try and let me know how it goes!

@harryyongheelee Great launch ! It looks interesting ! Expanding internationally will be much easier !

Yong Hee Lee

@adinda97 Thanks Adinda!

Yong Hee Lee

@mattisssa Upvote 💪

James Cooper

In the video, I saw that it can provide translations in three languages simultaneously, which is surprising! From what I saw before, most real-time translation tools are bilingual. Perhaps Cuckoo can translate even more languages at the same time?

Yong Hee Lee

@focusaur Yes indeed! Our customers would sometime choose up to 4 languages when they have different partners and customers join a meeting — say a game developer who has to sync across U.S., Korea China, and Vietnam!

James Cooper

@harryyongheelee That’s more than I imagined. Cool product!

Yong Hee Lee

@focusaur Thanks James!

@harryyongheelee 🎉 Huge congrats on the PH launch, Yong Hee and team Cuckoo! 🚀 Love how you’re solving a real pain point for global teams—especially the struggle with technical jargon getting lost in translation. The "contextualize with docs" feature is genius for accuracy (Snowflake/PagerDuty use cases speak volumes!). 🔥
Quick suggestion: Have you considered adding a "custom glossary" for company-specific terms? Could be a game-changer for niche industries! 🙌
P.S. As a remote team lead, I’d love to test Cuckoo in our multilingual sprint reviews—any plans for Slack/Miro integrations? 👀

Yong Hee Lee

@rocsheh Yes your feedback and question is spot on! We do have some custom glossary or preset keywords for industries like AI, Data, Tech, and Steel. We are hoping to expand this to other industries like bio, finance, etc.

Slack integration is coming soon. Meanwhile give it a try in your Zoom or Google Meet meetings and shoot me an email at yonghee@cuckoo.so for any question or help!

Mikita Aliaksandrovich

Congrats on the launch, Yong Hee and the Cuckoo team! 🎉 This is a game-changer for global teams, especially with real-time translation for technical meetings. Excited to see how this evolves! 👏

Yong Hee Lee

@mikita_aliaksandrovich We'll be able to help you out when you launch and people start to use your product around the world 🗺️

Jonas Urbonas

This is such a smart solution to a common problem! It's amazing how Cuckoo is making global collaboration smoother and more efficient, especially in technical discussions where every detail counts. How do you handle complex industry-specific jargon during translations to make sure nothing gets lost?

Yong Hee Lee

@jonurbonas Our users can input keywords like their company names and relevant technical terms. This makes sure we detect the terms accurately in both our speech and translation engine.

Marianna Tymchuk

Expanding internationally is challenging, but Cuckoo makes it easier with real-time AI translation and AI-powered meeting notes. This is a major win for global teams. Congrats on launching!

Yong Hee Lee

@marianna_tymchuk Thanks Marianna! Surprisingly, we've seen how companies are using us from Day 1 as they talk to users around the world. Hopefully we'll be able to help you as well as you launch!

Shant Hambarsoumian
Launching soon!

Congratulations on your Product Hunt launch! What you're building at Cuckoo addresses a real pain point for global teams. The ability to contextualize translations with relevant documents is particularly clever - that solves the exact problem of technical terminology getting lost in translation. It's impressive to see companies like Snowflake and PagerDuty already using your solution. The meeting notes feature that works across 20+ languages is a brilliant addition that completes the workflow. As someone who's experienced the awkwardness of bilingual meetings firsthand, I can see how Cuckoo could transform global business communication. Looking forward to seeing how you continue to evolve the product!

Yong Hee Lee

@shant_hambarsoumian Thanks Shant! I personally struggled juggling languages as an ad hoc translator and we have a lot of users who experienced the same struggle as us!

Malte Prüser

Yo this is actually genius. Using this on calls and speaking your native language / the language you're most comfortable with makes everyone feel comfortable and heard – awesome job!! 🥳

Yong Hee Lee

@maltepruser Thanks Malte! Let's break that language barriers!

Alan Rivera

Breaking the barrier for hiring the best talent not just the one you can communicate with! Tools like this is definitely the future congrats on such an awesome product and launch!

Yong Hee Lee

@alan_rivera Good point! Hiring the best talent takes time especially when you are entering a new market. We can definitely shorten that time!

Tutu Y

That's a great application of generative AI

lusons

"Setup interpretation on the fly" looks amazing!!!

Yong Hee Lee

@lusons ❤️

Ilkkan

Love it! I think Cuckoo has the potential to help global companies overcome language barriers, making collaboration seamless across teams worldwide.


Which languages will be supported? I noticed only three in the demo.

Yong Hee Lee

@isibol01 We have 20+ languages in support!

Amanda Zhu

Congrats on the launch team!!

Yong Hee Lee

@amanda_zhu Our Recall team!

Nazar Nosanenko

Breaking language barriers in real-time is no small feat. Cuckoo is providing a seamless way for teams to collaborate globally without relying on interpreters. Wishing you all the success with this launch!

Yong Hee Lee

@nazar_nosanenko Thanks Nazar 🙏

Yevheniya Afanasieva

Huge congratulations on the launch! The ability to customize translations with pitch decks and product manuals is a game-changer. Context-aware AI ensures clarity in technical discussions and sales calls. What’s been the most exciting use case so far?

Yong Hee Lee

@yevheniya_afanasieva Love this question. Companies have a lot of 1-on-1s and having a translation tool allow them to express their thoughts and feelings more authentically in their language, that otherwise they could have not expressed. These kinds of conversations are not something that we had in mind when we first started working on this!

Sungmin Im

Tried Cuckoo on my own to test its real-time translation, and it worked surprisingly well. The speech recognition was smooth, and the translations felt natural. Curious to see how it performs in an actual conversation!

Yong Hee Lee

@smins1063 Sungmin, thank you for trying it out. If you need someone to test it alongside you, I'd be happy to jump in a call. Let me know through my email!

Rita Ling
Love it! Such a great project. Congratulations on the launch!
Yong Hee Lee

@rita_ling Thanks Rita, hope you give it a try!
