Not every idea needs a designer. Sometimes you just need a poster for tonight’s event, a clean logo for a side project, or a shareable card, and you need it now. That is what Spark is for.
Spark is IsonAI’s visual creation tool. You describe what you want, and Spark builds a finished, self-contained visual you can preview instantly, refine in plain language, and export or share. Unlike image generation, Spark works in HTML and CSS, so the result can be a crisp poster, a real logo, an infographic, or even a small interactive page.
From a sentence to something you can use
Tell Spark what you have in mind (“a story-format poster for a coffee shop opening, warm tones, minimal”) and it returns a polished design in seconds. From there you keep talking to it: make the headline bigger, switch to a blue palette, add a call to action. Each round updates the same design, so you shape it visually instead of starting over.
When it looks right, you can export it to PNG or PDF, open the code to fine-tune it by hand, share it with a link, or save it to your collection to come back to later.
What’s new in this update
We rebuilt Spark to feel like a tool made for everyday use at scale:
- Stop whenever you want. While Spark is generating, the button becomes a Stop button. Change your mind mid-way and try a different direction immediately, without waiting for it to finish.
- Now in Bahasa Indonesia. The whole Spark interface follows your app language, so it reads naturally in Indonesian or English.
- Private, dependable exports. Turning a design into a PNG or PDF is processed privately, without reaching out to anything on the internet, so your export is fast and self-contained.
- Your edits stay put. Open the code, adjust it by hand, and your changes are kept with your creation; the next refinement builds on what you edited.
- Clearer limits. If you reach your daily limit, Spark tells you plainly instead of failing with a vague error.
- Built-in guardrails. Spark helps with mockups, personal brands, and class projects, and it declines requests designed to deceive, like fake login pages that impersonate a bank or brand to capture passwords. Legitimate creative work is unaffected.
Built and run in Indonesia
Like the rest of Epithre’s products, Spark runs on AI we build and operate ourselves in Indonesia. Your work is processed inside the country, and it stays yours.
Part of the Epithre family
Spark sits alongside the rest of what we make: Strata for reasoning over government regulation, IsonSearch for Indonesian web search, and IsonAI as the everyday assistant that understands local context and runs on local infrastructure. Spark brings that same idea to design: capable, considered, and made for how people here actually work.
