What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
Invoice editor: Client at the top, editable line items in the middle, total and preview action at the bottom.
States: Empty draft, validation errors beside each field, exporting, and a retry action that preserves the draft.
Hypothesis: Contractors need faster repeat invoices more than more templates.
First experiment: Test duplicating a previous job with five contractors. Watch where they hesitate before expanding the feature set.
The full kit adds a phased build plan, evidence notes, tool prompts, and implementation guidance. It is a plan for your coding agent, not a finished app.
Usage: Mechanics are fair game; never reuse the original name, branding, assets, or verbatim copy.

One song, one mood, your own AI music video. Some things are hard to say out loud, and some moments deserve more than a spot in your camera roll. Give a song to Sondo, add a photo or write down the story you want to tell, and the AI understands the rhythm, emotion, and lyrics in the music to generate the visuals, arrange the story, and finish the editing for you. In minutes, you can turn how you feel right now into a complete music video. No film crew, no editing skills, and no aligning the music frame by frame. All you have to do is tell Sondo what you want to express. Let the music tell your story It could be longing for someone, a relationship that has ended, an unforgettable trip, or simply an emotion that suddenly surfaced today. Sondo unfolds the story along with the music's emotion: when the melody grows quiet, the visuals slow down; when the chorus hits, the emotion is released along with the shots; and when the lyrics reach a key moment, the story responds on screen. Your music is no longer just sound—it now has characters, emotion, and a story. Make photos the star of your music video Choose a photo of yourself, a friend, family, or your pet, and let the people in the photo step into the world of music. With no filming required, you can turn an ordinary photo into a music video with movement, emotion, and a cinematic feel. Create what you truly want to express Here, you can: Make a complete music video for your own original song so more people can hear and see your work; Use a song to capture birthdays, trips, anniversaries, and important moments; Turn your wedding memories into a love story you can replay anytime; Make a music video that belongs only to you and someone you miss; Express how you feel through creative visuals you can share; Make a friend, family member, or pet the star of a music video; Follow trending music to quickly make short videos with rhythm and a story. More than music videos AI music creation: Write a sentence, a story, or a few lines of lyrics, and the AI can generate an original song of your own. It supports many music styles including pop, rap, rock, and jazz, and you can go straight on to generate a music video. Diverse visual expression: You can describe the mood you want, such as warm, lonely, passionate, romantic, or nostalgic. Based on your emotion, the AI chooses more fitting visuals and shots, rather than simply applying a single visual style. Music can capture your experiences, and it can also express the things you never said out loud. Let your music be not only heard, but also seen.

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
From the Build Kit assessment.
A reliable timeline needs an agreed scope and a technical check. Ask your agent to estimate the phases in BUILD_PLAN.md after that review.
