AI Investment Without Returns
Businesses are investing heavily in AI experimentation, yet many struggle to turn promising proofs of concept into production-ready applications that deliver measurable business value.
toPrompt helps you turn an idea into a working application using AI. When you’re ready to launch, NineHertz engineers can help with integrations, security hardening, deployment and ongoing development.
Working application
toPrompt is a solution from The NineHertz, an AI-native engineering partner
toPrompt is an AI app builder from The NineHertz that turns plain-language prompts into working web and native mobile applications, then puts real engineers behind them. Write the prompt yourself or have a toPrompt prompt engineer write it, build from a ready-made design library, and get a working prototype in 5–10 days. When the app needs integrations, security hardening or scale, the same NineHertz team takes it to production and supports it after launch. One team from prompt to post-launch. No separate dev team to hire.
It is built for solopreneurs testing an idea, startups racing to an investor-ready MVP, small businesses that need custom software without an agency budget, and enterprises that want internal tools without adding headcount. You own 100% of the code. Download it, host it, extend it.
From the first prompt to the next stage of development, you have a path to keep building.
We don’t compete with vibe coding. We complete it.
The gap between an idea and a working application is rarely the code alone. It is the specs, tickets, handoffs and rework that sit in between, spread across tools and teams.
Businesses are investing heavily in AI experimentation, yet many struggle to turn promising proofs of concept into production-ready applications that deliver measurable business value.
Traditional application development requires significant investment in engineering talent, infrastructure, and delivery. This forces businesses to prioritize a handful of initiatives while other valuable ideas remain on the backlog.
Engineering teams are stretched across new development, maintenance, bug fixes, and technical debt, leaving limited capacity to experiment, innovate, and respond to changing business needs.
AI can accelerate application creation, but integration, security, testing, performance, and deployment remain critical hurdles between an impressive prototype and a production-ready solution.
What the toPrompt builder does, and where NineHertz engineering takes over.
Describe what you want in natural language. toPrompt turns your requirements into an initial application you can review, test, and refine as your idea evolves.
Build web apps and, on eligible plans, native iOS and Android apps. NineHertz engineers can support testing and submission to the App Store and Google Play.
Start from ready-made templates for landing pages, dashboards, and client portals, or import Figma designs to shape the app’s visual structure.
Access your application’s source code to customise, extend, and continue development outside toPrompt. Code ownership is subject to the platform’s terms.
Eligible plans include security scanning, monitoring, architecture diagrams, and technical docs. Further testing and compliance needs are assessed against production requirements.
Publish applications beyond local prototypes. NineHertz can support deployment planning, environment configuration, and launch readiness.
Connect apps to external services through APIs. NineHertz can build custom integrations with your existing business systems and workflows.
NineHertz engineers add custom functionality, system integrations, code review, deployment, and ongoing development to take your app from working to production-ready.
Bring an idea, a design or code built in another tool. toPrompt generates the app in days. When it’s time to go live, NineHertz engineers partner in to harden, launch and scale it.
* Included on paid build plans. Integrations, load testing, compliance and hypercare are delivered by NineHertz engineers through Prompt & Partner engagements.

What changes when ideas move to production faster.
Move from an idea to a working application faster, shortening the journey from concept to execution.
Validate ideas and build functional prototypes without committing to the cost and complexity of traditional development upfront.
Empower teams to translate business needs into applications using natural-language prompts, reducing dependence on lengthy development cycles.
Go beyond AI-generated code with NineHertz architects reviewing, refining, and helping take applications live in as little as a week, depending on scope and complexity.
Iterate, adapt, and improve applications as business requirements evolve, without restarting the development process from scratch.
Every app, team and market is different, so we don’t promise generic percentages. Tell us where you are today, and we’ll agree on measurable goals for time to launch, build cost and post-launch stability.
Watch one prompt become a working app, then follow it from first build to live launch.
What you’ll see
Accelerators built by the same engineering team, for the work that runs your business after launch.
AI agents that watch your infrastructure around the clock, spot incidents early and run the fix, so on-call engineers only step in when it counts.
Connect people, systems and AI agents into one governed workflow, with approvals, hand-offs and audit trails built into every step.
A CRM that updates itself. Emails, calls and meetings flow into contacts and deals automatically, so the pipeline stays current with no manual data entry.
An AI support agent that resolves customer queries across chat and email from your knowledge base, and hands complex cases to your team with full context.
Use toPrompt to explore your idea and create an initial application. When you’re ready to go further, NineHertz can help you plan the engineering work needed to integrate, test, deploy and evolve your application.
Answers to the questions founders and product teams ask before they start building.
toPrompt is an AI-powered application builder from The NineHertz. It helps turn plain-language instructions into an initial application. When additional engineering is needed, NineHertz can help assess the application and scope the work required for integrations, testing, deployment and ongoing development.
No. You describe what you want in plain language, and toPrompt generates the initial application. Developers who want more control can use the code editing capabilities and download the source code.
You can build landing pages, web applications and mobile applications. Typical examples include booking and membership platforms, community apps, online stores, client portals, dashboards and internal business tools.
toPrompt combines AI-assisted application development with access to NineHertz engineering services. You can start by building an application yourself and engage engineers when you need additional technical expertise. Depending on your requirements, this can include integrations, security improvements, testing, deployment and ongoing support.
Yes, NineHertz can assess applications built with other AI tools, subject to access, technical feasibility and the agreed scope. The assessment can identify areas that may require code changes, security improvements, integrations, testing or deployment work. The proposed approach, cost and timeline depend on the application’s current state and requirements.
toPrompt offers self-service plans and engineer-assisted engagements. The self-service option provides access to the product according to the selected plan, while Prompt & Partner engagements cover additional engineering work based on an agreed scope.
Self-service plans currently start at $0 (Free), $7 for 7 days (Starter) and $29 a month (Pro); see the current pricing on toprompt.ai. Engineer-assisted projects are scoped according to the application, required integrations, technical complexity and delivery requirements.
Under toPrompt’s terms, you own your projects and source code, and you can download the code to use outside toPrompt. For engineer-assisted projects, ownership and handover are also set out in the project agreement.
Enterprise readiness depends on the application’s architecture, data, integrations and security requirements. toPrompt provides the capabilities included in the selected plan, while NineHertz can help assess additional requirements and scope appropriate engineering work. Depending on the project, this may include authentication, access controls, security testing, monitoring and deployment controls. Enterprise security and compliance requirements are confirmed during project scoping.
Applications may require integrations with systems such as CRMs, ERPs, payment services, analytics platforms and identity providers. NineHertz can assess these requirements and scope the integration work based on the systems involved, available interfaces, data flows and security considerations. The supported integrations and delivery scope depend on the application and the agreed engagement.
Start by exploring the toPrompt builder and creating an initial application. If you already have an application that needs additional engineering work, or you know that your project requires integrations, testing or deployment support, contact NineHertz to discuss the requirements and next steps.
