A full IDE and a build agent that run on any laptop, desktop or phone, and take mobile money, not a card.

It plans, then writes, then shows you what changed
Hand the work to the agent and keep the decisions. You describe the app. HEWA writes a plan with the credit cost, then the files. In chat, the agent proposes commands and waits for a yes. A build writes its files, installs and previews; every file it wrote can be undone with one click.

What keeps a bad build cheap
In chat, the agent proposes commands and waits for a yes. A build writes its files, installs and previews; every file it wrote can be undone with one click. Stop before the reply finishes and that request is not charged.
- Approve, edit or reject commands the agent wants to runNothing runs in your project until you say yes.
- Review and accept/reject proposed edits (per file and per hunk)Approve each change before it lands in your files.
- Keep / Undo for an applied agent editRoll back an edit you do not like with one click.
- Stop button; no charge if stopped before output completesChange your mind mid-build and you do not pay for what you stopped early.
Say what you want, in plain words
Six prompts to start with, written the way you would type them. The agent reads the project, plans the steps, then writes the files.

- Mobile Make a USSD-style menu for airtime top-ups
- Data Create an inventory tracker with low-stock alerts
- Bots Wire a WhatsApp order bot to my product list

Questions people ask first
What does a credit buy?
One request to the agent. HEWA Smart, HEWA Fast, HEWA Africa, HEWA Long, HEWA General cost 1 credit per request; HEWA Reason costs 3 credits and HEWA Pro 5 credits. The cost is shown next to the model before you send. A credit is KES 12 with VAT included, and credits don't expire.
Which devices and browsers work?
Chrome and Edge on a laptop or desktop; on an Android phone, the editor, agent and preview in Chrome. In Safari and on iOS you can edit, build, preview and export, but the terminal is not available there. There is nothing to install, and you can add HEWA to your home screen like an app.
Which languages can I use?
Voice input is live in English, Kiswahili, French, Amharic, Hausa, Yoruba and Arabic: speak, and HEWA writes the prompt down. The interface is available in English, Kiswahili, French and Arabic, with six more languages in the switcher.
How do I pay?
By mobile money, card or bank transfer. Choose any amount from KES 35 to KES 3,500 (KES 120 is 10 credits), confirm the prompt on your phone, and the credits land in your wallet. Every top-up comes with a VAT receipt you can download as a PDF.
Does it work on a slow connection?
Yes, within limits. A network indicator in the header shows whether you are on 4G, 3G or 2G and what the connection can handle. If the network drops you keep editing and your changes sync when it returns. Inline autocomplete is built for slow links.
Can my team use it?
Yes. Create an organisation, invite teammates and give them roles, and work on the same project. Share one organisation wallet, or let each person spend from their own.
