System Designer is a low-code development platform for creating systems. No matter the frameworks you use and the code you write, the most important is the model that you define to create your system. System Designer helps you to design this model and to generate the classes and components to build your system. DESIGN YOUR SYSTEM WITH EASE If you look at the different JavaScript frameworks on the market, you will notice that they all have their own way to define a model, generally only with code. System Designer uses UML, a standard, to define your model. So you probably already know how to design in System Designer even if you have never run it. The definition of the model is stored on a JSON format called MSON. With MSON you can define types, classes, one to one / one to many relationships and multi inheritance between classes. CODE THE BEHAVIOR OF YOUR SYSTEM Once you have created your model, System Designer generates the skeletons of all your methods. You only have then to add your code to implement them. System Designer provides you helpers to manage your components. You can easily navigate threw your components to create your application. CREATE COMPONENTS GRAPHICALLY There is no need to code to instantiate a component. Create a component in System Designer is like creating a document in a NoSQL Database. In fact, System Designer acts as an ODM (Object-Document Mapper) to manage your components as NoSQL Documents. RUN YOUR SYSTEM You can run your system directly from System Designer. Because you have defined a model for your application, a Dynamic Type Check is done on every action of your system. All warnings are send and shown in System Designer. DESIGN ON THE GO System Designer can be used on macOS, iPad or any browsers. System Designer has a Github module to synchronize your work between all these apps. You can begin your design on your Mac and then continue it on your iPad.

PRIVACY AND CONTROL, FULLY ON-DEVICE: TRANSCRIPTION, SUMMARIES, SEARCH AND Q&A Daisy records meetings and voice notes, transcribes them, tells the speakers apart and writes the summary — on your iPhone or iPad. Audio, transcripts and voiceprints stay on the device. No vendor or 3rd party that receives your recordings unless you choose to. Planning a trip with friends? A conversation that could become a podcast episode? Customer discussing their needs? Record it once and use it for anything you need. And sometimes your name came up in a meeting, but you really needed to buy those shoes online right at that moment... You know who you are. Daisy is free for 30 days. After that, a subscription is required for new recordings. Everything you already recorded stays available. Languages supported: English, French, German, Italian, Spanish, Portuguese, Mandarin, Japanese and Korean. PRIVATE BY ARCHITECTURE • Recording, live captions, transcription with on-device speech models, speaker identification and summaries that run on your iPhone or iPad • Works in airplane mode. • Built for confidential work: interviews, client calls and notes governed by HIPAA, legal privilege or an NDA stay on this device SUMMARIES, YOUR WAY Choose between Gemma 4 by Google, an open-weight model or Apple Intelligence on-device. Settings can point Daisy at 3rd-party AI providers with your own API key, or at LM Studio or Ollama running on your own computer. The transcript text goes to the provider you chose, and only then. ASK YOUR OWN MEETINGS Ask a question and Daisy answers from your own recordings, citing the moments it drew on. Search runs on the device across everything you have recorded. VOICES Enrol your own voice once and Daisy names you across meetings. Name the other speakers after a meeting and the transcript follows. NOTES AS YOU TALK Anything you note stays with the recording. FROM YOUR WRIST The phone records; Apple Watch shows the timer and carries the controls. YOUR DAY, READY TO RECORD Integrate to your calendars so that you can one-tap start recordings, titled and tagged. iPHONE, iPAD, MAC Record on the phone, finish at the desk. Daisy syncs with the Mac app over your own network, device to device. BUILT FOR THE ROOM Daisy was tuned on real meetings: several people around a table, one phone in the middle. It works as well for a voice memo dictated on a walk. RECORDING OTHER PEOPLE Recording-consent laws vary by place. Before the first recording Daisy asks you to acknowledge that you will get the consent the law and your participants require. Daisy is made by Small Bricktory.
