SpeechGPT

What is SpeechGPT?
SpeechGPT lets you hold voice conversations in the browser using your own OpenAI API key. You type or record messages, send them through a chat interface, and hear spoken replies without installing desktop software.
Unlike hosted TTS services that bundle model costs into a subscription, SpeechGPT runs in the browser and bills you only through the OpenAI, Azure Speech Services, or Amazon Polly accounts you connect. That makes it a lightweight option for developers and language learners who already have API access and want a simple voice chat front end.
The interface supports English, Spanish, and Chinese UI labels, includes a record button for speech input, and stores session data locally in the browser. It suits developers testing voice chat flows, language learners practicing spoken prompts, and anyone who wants a minimal ChatGPT voice client on mobile or desktop.
Endel

What is Endel?
Endel generates personalized soundscapes that adapt in real time to help you focus, relax, sleep, or stay grounded during activity. The audio engine uses patented Endel Pacific technology that reacts to inputs like time of day, weather, heart rate, and location instead of looping static tracks. The marketing site describes it as neuroscience-backed functional audio for everyday wellness.
Playlist apps give you fixed songs; Endel keeps regenerating sound on the device so the mix shifts with your context. Focus mode claims up to a 7x increase in sustained concentration versus playlists in peer-reviewed research cited on the site, and Relax, Sleep, and Activity modes each ship with generative visuals. The same engine runs across iOS, Android, macOS, web, Apple Watch, Alexa, Apple TV, and Fire TV.
Students, remote workers, people with ADHD, parents, and anyone fighting insomnia are the implied audience from focus and sleep landing pages plus App Store reviews quoted on endel.io. A free edition exists, while Premium unlocks all modes, offline playback, wearable integrations, and artist collaboration soundscapes like James Blake: Wind Down.
