Bihar’s First AI Startup
AI Website & App Builder
Build websites and apps with a simple prompt.
Describe what you want to create. LineItem helps turn your idea into a web experience you can preview, improve, and take further — without starting from a blank project.
Web app or Mobile app. Same key builds both — web and mobile.
Start building — describe the app you want to build. Free to build with — DeepSeek included, no key needed. Never paste a key in chat.
Try: Build an expense tracker with categories, charts and a clean dashboard. Or: Habit tracker with a weekly view · Landing page for a bakery · Expense splitter for flatmates · Quiz game about space
What LineItem can do
- Prompt-based editing
- Responsive previews
- Code download
- Version history
- Installable PWA
- GitHub push
Four steps. No blank project.
You describe; the builder writes the first version; you refine it in plain words; the finished app is a file you own.
Describe your idea.
Write one sentence about the app you want — a habit tracker, a booking page, a store.
Get a first draft.
LineItem writes the first version of the app — one HTML file, ready to look at.
Preview and refine.
Click through the working preview, then describe changes in the chat. Every version is kept.
Take it with you.
Download the HTML file, share a link, or push to GitHub. The file is yours to host anywhere.
Everything you need to ship a small app.
Nothing you don’t. No backend, no database, no login system in version 1 — the builder says so honestly and offers a browser-storage version instead.
Your key, any of six providers
Bring a key from Zhipu, Qwen, DeepSeek, OpenAI, Anthropic, or OpenRouter. It stays in your browser; the provider bills you at their own rates, and LineItem adds nothing.
Web and mobile from one prompt
Pick Web app or Mobile app before you start. The mobile build is a real installable PWA, and one key covers both.
Push to GitHub
Send any project to a public GitHub repo in one click, from the builder. Your code lives where you can keep working on it.
Download it, share it
Every app downloads as one HTML file you own outright. Share a link, or host the file anywhere — no LineItem account needed to view it.
Start from a template
Five working starting points: a dashboard, a store, a booking page, a game, a tool. Pick one and make it yours.
DeepSeek included, 10 builds a day
No key? No problem. The platform’s DeepSeek builds are included — 10 a day, free. When they run out, add your own key or come back tomorrow.
From a sentence to a working app.
Three stages on one screen: describe it, watch the preview build, refine it until it is yours.
1. Describe it in the chat
Type the idea, attach a screenshot, or speak it in Hindi. The chat keeps the whole conversation, so a change is one more sentence.
2. Watch the preview build
The preview pane shows the working app as it is written — desktop, tablet, or phone width. Click through it like a user would.
3. Refine, version, download
Each generation becomes a version you can restore. When it is ready, download the HTML file, share a link, or push to GitHub.
Start somewhere useful.
Five working templates — each one starts a real build, ready for your edits.
Analytics dashboard
See the numbers at a glance.
Online store
Show products and test a cart.
Booking page
Let visitors pick a time.
Browser game
Make something people can play.
Utility tool
Turn one repetitive task into a tool.
Web + mobile (PWA). Stores check out with a form, not real payments. Bookings and game scores stay in the browser. No database, login, or payments in version 1.
One builder, many small apps.
LineItem builds single-file front-end apps — no backend, no database, no login system in version 1. Within that honest scope, it covers a surprising amount of everyday software.
Build web apps from a plain-language prompt
Describe the tool you need — a tracker, a converter, a calculator — and get a working front-end app you can use the same day. If the idea needs a database or login later, the downloaded file is a plain HTML starting point a developer can extend.
Create landing pages and business websites
A bakery page, a clinic booking page, a portfolio: describe the business and the sections you want, then refine the words and layout in the chat. The page downloads as one file, ready to host anywhere.
Prototype dashboards and internal tools
A KPI dashboard, a rota viewer, a stock checker — the kind of small internal page that never gets built because it is not worth a sprint. Build it in an afternoon, share the link with the team, and keep the file.
Free to build. The AI bill goes to your provider.
LineItem costs $0. The tokens your builds use are billed by your own AI provider — or use the included DeepSeek builds. Other builders charge a subscription and sell you their credits on top. Here is the difference, checked 15 November 2026.
| LineItem | Lovable | Bolt.new | v0 | Replit | Emergent | |
|---|---|---|---|---|---|---|
| Price to build seriously | $0 — the platform is free | From $25/mo (Pro) | From $25/mo (Pro) | From $30/user/mo (Plus) | From $20/mo (Core) | From $20/mo (Standard) |
| How AI usage is charged | Your provider’s own rates — no markup | Credits, per message | Tokens, per month | Dollar credits, per token | Credits, per checkpoint (effort-based) | Credits, per task |
| Free tier | DeepSeek included, 10 builds/day | 5 build credits/day, max 30/mo | 1M tokens/mo, 300K/day | 7 messages/day | No free plan on the rate card | 10 credits/mo |
| Your own key runs the builder | Yes — 6 providers | No | No | No | No | Yes |
| What it builds | Front-end apps + mobile PWA (no backend in v1) | Full-stack web apps | Full-stack web apps | Full-stack web apps | Full-stack apps, hosted | Full-stack web + mobile apps |
| Code export | Download the HTML file, any time | GitHub sync, download on paid plans | GitHub sync | GitHub sync | GitHub sync or ZIP download | GitHub export on paid plans |
Prices and limits checked 15 November 2026, from each company’s own pricing page — except Lovable’s price, from published pricing reports. They change — check before you pay. LineItem’s own pricing is on the pricing page.
Frequently asked questions
Is it really free?
The platform is free: every builder feature, unlimited projects. DeepSeek V4.1 Flash is included — 10 builds a day, no key needed. Beyond that, or on other models, you pay your AI provider directly for the tokens your builds use — with your own key, DeepSeek V4.1 Flash costs from $0.15 per 1M input tokens off-peak (peak hours cost double). If you want $0 usage, the free GLM-4.7-Flash model costs $0 with your own free key. The free tier shows placeholder ad slots; Pro ($20/month, billing opens soon) removes them. See “What free means” in the docs for the full cost stack.
Where does my API key live?
Only in your browser. Keys are stored in your browser’s local storage and are never sent to our servers on the direct path. If your browser cannot reach a provider directly, the request goes through a thin relay that forwards it and forgets the key — it never stores or logs it. Never paste a key into the chat. Included DeepSeek builds use the platform’s key through our relay — it is never shown to you and never stored in your browser.
What kind of apps can I build?
Single-file front-end apps: landing pages, tools, dashboards, games, booking pages, stores — as a website, or as an installable mobile app (PWA). Pick Web app or Mobile app before you start; the same key builds both. Version 1 has no database or user login — if you ask for one, the builder says so honestly and offers a browser-storage version instead.
Can I build mobile apps?
Yes. Pick Mobile app before you start, and LineItem builds an installable mobile app — a PWA, installed from the browser onto a phone home screen. It is not a native app-store build: there is no App Store or Google Play package in version 1, and we will not pretend otherwise. One key builds both web and mobile, and web and mobile builds share the same 10-builds-a-day included allowance.
Do I own the code?
Yes. Download the app as one HTML file at any time and host it anywhere. The download is the complete app — it does not include a database, login system, or hosting, because version 1 apps do not have those.
Do I need to know how to code?
No. You describe the app in plain words and the AI writes the code. If you can read code, you can open the downloaded file and edit it — it is one plain HTML file, no build step, no framework to install. If you cannot, you never have to look at it.
How is LineItem different from Lovable or Bolt?
Three differences. First, the platform itself is free and stays free — you pay your AI provider directly, or use the included DeepSeek builds. Second, your keys stay in your browser, and the app you build downloads as one HTML file you own outright. Third, LineItem is honest about scope: version 1 builds front-end-only apps, with no database or login. Lovable and Bolt offer backends — if you need one today, they are the better fit, and their free tiers cover small projects.
