Remember when The Beatles got together for one last song? It got mixed reviews, but the fact that one of the biggest bands of all time embraced AI set a precedent. AI was going to change the music industry. From writing songs to generating entire tracks, many predicted an AI-powered musical revolution.

TwoShot is one of those AI apps looking to make its mark on the music scene. Launched last week, It is focused on making music accessible to all by letting you craft tracks with your voice, text prompt, or just by humming into a mic. 

Say you’re working on a lo-fi track to stimulate productivity. You can instruct TwoShot to generate a “melody of flutes inspired by nature” and then pair it with a chill drum line by beatboxing into your mic. The AI will turn it into a full-fledged, professional-sounding track. 

It also comes with a library of over 200,000 samples, ranging from rock to country music and everything in between, that you can grab for inspiration or even use the AI to remix into something new to create your next banger. 

One of the most powerful features is TwoShot's plethora of different models. While building your track, you can swap your chosen AI model at any stage for a different one, including ones built by big names. Say you want your lyrics to have a female voice. You can load up the “Grimes” model with your prompt or existing sounds, and it will work it into a more Grimes-esque sound.

Alongside that, these models are “ethically trained,” according to the team, meaning they usually have attained artist permission to use their likeness or have worked with them to create the model itself, like in the case of the Grimes one above. 

Of course, TwoShot isn’t the only platform looking to change up the music scene. Spotify recently launched AI playlists, a new tool that lets you generate playlists with a prompt, and Meta launched AudioCraft last year as a tool for making songs with AI.

Building apps has become easier over the past few years thanks to APIs, frameworks, and SDKs. These tools make it faster to implement features that, say, twenty years ago, would have taken weeks, if not months, to build by yourself. 

One of the features that is still notoriously difficult to implement is real-time collaboration. The cursors and comments of your teammates in your Figma design that you might take for granted is no small feat, and in today’s remote work world, reliable, real-time collaboration is critical to any team software. 

Liveblocks is a platform built to make it easier to implement these features. It was founded by Steven Fabre and Guillaume Salles in 2021 as a live presence API showing which team members were viewing a document. Since then, it has raised $5 million in seed funding to expand its capabilities, and the team just launched the latest update.

So what’s new? Since its initial launch, the team has doubled down on its efforts to become an all-in-one collaboration suite for your products. The latest update expands beyond live presence functionality to include more complex features like real-time text editing, live commenting, and real-time notifications when your team makes edits or suggestions. 

It also ships with “Realtime APIs,” so if something is missing that your team can’t live without, you can build it with the Liveblocks service.

The handy thing about this is that every feature includes fully-styled default components. If you need to implement comments and aren’t too fussy about the specifics, you can theoretically add them to your app in moments. Components even include dark mode by default.

It's in pretty good company too with companies like Zapier, Vercel, Hashnode, and others all using Liveblocks to power their suite of real-time collaboration features.
