Text to app — the whole loop.
“Text to app” is the promise of typing a description and receiving working software. opix delivers the unglamorous full version: your text becomes a real Next.js app with a database, the preview streams live, and the same loop — describe, look, refine — carries you from first draft to shipped product.

What text-to-app actually means
Between your sentence and a working app sit a dozen decisions: pages, data model, navigation, design language, what happens on error. A text-to-app system is really a decision-making system — the text is the brief, and the quality of the result depends on how well the machine fills the gaps you left.
opix fills them conservatively and shows its work: it plans the structure, writes real files you can watch stream in, checks that its own output compiles and runs, and presents a clickable preview in about two minutes. Where the brief was ambiguous, you correct by pointing — which beats specifying everything upfront, because nobody can.
How to write a prompt that builds well
State the job, the user, and the core objects. “A booking tool for a hair salon: customers pick a service, stylist and time; staff see a daily calendar” beats “make me a booking app” — not because opix can’t fill gaps, but because your gaps get your defaults.
Name the vibe, or show it. “Clean, editorial, lots of white space” steers the design language; attaching up to four screenshots of sites you like steers it harder. opix locks one art direction and applies it consistently across the build.
Say what matters most. If the admin view is the product, lead with it. And for anything non-trivial, start in plan mode: opix drafts the plan, you approve or redirect, and generation only starts once the direction is right — no credits spent guessing.
The loop after the first build
Point, don’t re-prompt
Click the exact element in the preview and describe the change. opix maps it back to the source and edits only that.
Screenshots as language
Paste a screenshot of the bug — or of any site whose style you want. Pictures resolve ambiguity that paragraphs can’t.
Versions as save points
Every iteration is a restorable version. Try the risky idea; rolling back is one click.
Grow it by describing
“Add login.” “Add a chatbot with a $10 cap.” “Make the dashboard exportable.” Features arrive the same way the app did.
From toy to tool
Text-to-app demos usually stop at the screenshot stage. The loop only matters if it survives contact with reality: real data (your own Postgres), real accounts (auth generated in), real money (your Stripe via connectors), real domains — and an exit (GitHub export, eject anywhere).
That’s the standard to hold any text-to-app tool to, including us: if the text ever stops working, you should be able to open the code and keep going. On opix, you can.

Asked before you asked.
How long does text-to-app take?+
The first clickable preview arrives in about two minutes. Refinements — a section changed, a feature added — typically land in under a minute each, streamed live so you watch them happen.
How specific does my text need to be?+
A sentence works; a spec works better. The practical rule: name the user, the job and the few things you have strong opinions about. For anything ambitious, plan mode lets you approve the interpretation before the build starts.
Can it match a design I have in mind?+
Attach up to four screenshots — your current site, competitors, anything whose vibe you want — and opix folds them into the design language. Words like “warm, editorial, generous white space” steer it too.
What kinds of apps work best?+
Full-stack web apps: marketing sites, dashboards, SaaS tools, booking and admin systems, storefronts. Native mobile apps and heavy real-time systems (games, trading engines) are outside the sweet spot — we’d rather say so here than after your first build.
What if the result is wrong?+
Point at it — click the element or paste a screenshot — and describe what should be different. Failed builds and auto-fixes are free, so refining costs you nothing but the successful changes you keep.
Do I keep what the text produced?+
Entirely. The output is a standard Next.js repository on your own Postgres database: export it to GitHub, eject to your own hosting, or keep shipping from opix. Your text, your app, your code.
