A Lovable alternative where the app is the beginning, not the deliverable
Assistant Cortex is a Lovable alternative that builds applications from plain-language briefs — and then runs them on a platform with AI phone, email and sales agents, a marketplace of installable applications, and more than 80 AI models to choose from. Lovable hands you a codebase. Assistant Cortex hands you a running business system.
No vendor assembly afterwards — the agents, the channels and the permissions are already there when your app lands.
Where Lovable is genuinely good
Lovable has earned its place as one of the leading AI app builders, and for some jobs it is exactly the right tool.
Full-stack MVPs, fast
A prompt becomes a complete React and TypeScript application — frontend, backend, database and authentication — with native Supabase integration and Stripe payments.
You own the code
GitHub sync gives you a real codebase you can take into any IDE, and Lovable Cloud now ships an official export path. For a product you plan to hand to an engineering team, that portability matters.
One-click shipping
Deployment, custom domains and previews are built in, so an idea can be live in an afternoon.
The question Lovable can’t answer: who runs the app?
When Lovable finishes, you have software. You still need the people — or the agents — who answer its phone line, work its inbox and chase its leads, and you assemble those from separate vendors. Assistant Cortex starts from the other end: the agent workforce is the platform, and new applications are built into it.
A workforce, on day one
- AI phone agents answer and place real calls, with recordings, transcripts and reasoning traces.
- AI email agents read, classify and answer mailboxes on schedules you control.
- An AI sales pipeline tracks leads and drives agent-assisted outreach from first contact to close.
- Knowledge bases your agents search and cite in their answers.
A platform, not a pile of apps
- A marketplace of applications and AI abilities that install with a click.
- Shared governance: user groups and per-application ACL permissions apply to every module, new or installed.
- Model freedom: more than 80 preconfigured AI models across 15 types, custom models included.
- MCP native: a built-in MCP client and server, so outside tools reach your agents and your abilities reach outside clients.
Assistant Cortex vs Lovable at a glance
Both products turn a plain-language brief into a working application. What surrounds that application is where they part ways.
| Capability | Assistant Cortex | Lovable |
|---|---|---|
| Prompt-to-app building | Yes — the Coding Sandbox builds, tests and publishes modules into your marketplace | Yes — generates full-stack React/TypeScript apps with Supabase and GitHub sync |
| AI phone agents | Yes — agents answer and place real phone calls, with recordings, transcripts and reasoning traces | Not offered |
| AI email agents | Yes — mailboxes agents read, classify and answer on schedules you control | Not offered |
| Module marketplace | Yes — applications and AI abilities install with a click | No — each generated app is deployed on its own |
| AI model choice | 80+ preconfigured models across 15 types; custom models supported | Uses the platform’s built-in generation models |
| Team governance | User groups and per-application ACL permissions shared across every module | Authentication and roles inside each generated app |
| MCP support | MCP native — a built-in MCP client and server; abilities are published as MCP tools | MCP integration for building apps from Claude |

Keep shipping by prompt — after launch, inside the platform
The Coding Sandbox is Lovable’s build-by-prompt workflow applied to a living platform. Write a brief, watch the build, and approve the result — a new application published into your own marketplace, running under your existing users, groups and permissions from its first minute.
- Isolated builds. Every project runs on its own sandbox and is tested against the live platform before you see it.
- Approve to publish. Nothing reaches your marketplace until you sign off.
- Agents can use it too. A module can ship AI abilities, which your agents call in conversation and the MCP server publishes to outside clients.
- Proof, not promise. A notes app, a 3D Rubik’s cube solver, an interactive chat card and a telnet server — four working modules from four short briefs.
Channels an exported codebase doesn’t come with
A generated codebase gives you a web app. Your customers also call, text and email — and wiring a voice vendor, a mailbox processor and a CRM to a fresh MVP is exactly the integration project you were trying to avoid.
- Phone, SMS and email are platform channels, answered by the same agents with the same knowledge and permissions.
- Every interaction is recorded — transcripts, reasoning traces and analytics without a separate reporting tool.
- Agents render live UI in chat — buttons, previews and controls instead of paragraphs.
Which should you choose?
Choose Lovable when…
- The deliverable is the codebase — a product your engineering team will take over in an IDE.
- You want a standalone SaaS MVP on the standard React/Supabase stack, shipped this week.
- Your product has no need for phone, email or sales agents around it.
Choose Assistant Cortex when…
- You are running a business, not shipping a repo — and the phone, the inbox and the pipeline need working agents.
- You want each new app to join a governed platform instead of becoming another deployment to babysit.
- You want to pick the models behind everything — 80+ preconfigured, custom ones included.
Frequently asked questions
Is Assistant Cortex an app builder like Lovable?
It contains one. The Coding Sandbox builds applications from plain-language briefs the way Lovable does — but the result is a module published into a running platform with agents, channels and shared permissions, rather than a standalone codebase you deploy and operate yourself.
Does Lovable have AI phone or email agents?
No. Lovable builds and deploys web applications; it does not run agents that answer phone calls or work mailboxes. Assistant Cortex agents answer and place real calls and manage email on schedules, with recordings, transcripts and reasoning traces.
Lovable gives me the code. What does Assistant Cortex give me?
A running system. Modules built by the Coding Sandbox are real TypeScript and Angular code, built and tested on an isolated sandbox — but they publish into your platform’s marketplace, where installation, users, permissions and the AI models behind them are already managed for you.
Can my whole team use it, with different permissions?
Yes. User groups control access to agents, AI abilities and applications, and each application carries fine-grained ACL permissions — one permission system across everything, set once rather than rebuilt inside every app.
How does Assistant Cortex compare to Base44 or Lindy?
Base44 is an all-in-one app builder inside the Wix family; Lindy is an AI-employee platform without app building. Assistant Cortex covers both jobs on one platform. See the Base44 comparison and the Lindy comparison.
Ship the app — and the workforce behind it
Start a trial, brief the Coding Sandbox, and let your new application launch inside a platform where the agents are already working.
