A Base44 alternative for teams that need agents, not just apps
Assistant Cortex is a Base44 alternative that combines prompt-to-app building with AI phone, email and sales agents, a marketplace of installable applications, and support for more than 80 AI models. Base44 turns a prompt into a standalone app. Assistant Cortex turns a prompt into a module of a platform that is already answering your phone.
Same starting point — describe what you want in plain language. Very different ending point.
Where Base44 is genuinely good
Credit where it is due: Base44, now part of Wix, is one of the fastest ways for a non-technical builder to get a working app. If any of these three things is your whole requirement, it is a fine choice.
Everything built in
Hosting, a database, user authentication and role-based permissions come with every generated app, plus integrations for email sending, SMS, payments and file upload — no external services to wire up.
Fast for non-technical builders
The fewest decisions between a prompt and a working app. For an internal tool or an MVP built by someone who never wants to see code, that focus is a real strength.
Background Superagents
Base44’s Superagents run always-on background tasks and connect to external tools, so generated apps can automate work rather than just store records.
What changes when the app is part of a platform
A Base44 app stands alone: its own login, its own database, its own island. An Assistant Cortex module lands inside a platform where your agents, your user groups and your other applications already live — and everything shares one set of permissions.
Your apps join a marketplace
- Install, don’t rebuild. Phone, email, knowledge bases, image and audio generation and dozens more applications install with a click.
- Build what’s missing. The Coding Sandbox turns a written brief into a new module, tests it against the live platform, and publishes it to your marketplace when you approve it.
- One login, one permission system. Every module answers to the same user groups and ACL permissions, so access control is set once, not once per app.
Your agents pick up the phone
- Real phone calls. AI phone agents answer and place calls on real numbers, with recordings, transcripts and reasoning traces.
- Real mailboxes. Email agents read, classify and answer mail on schedules you control.
- A working pipeline. The AI Sales Pipeline tracks leads and drives agent-assisted outreach from first contact to close.
- Your choice of models. More than 80 preconfigured AI models across 15 model types, with custom models supported.
Assistant Cortex vs Base44 at a glance
Both products build applications from a plain-language prompt. The differences start the moment the app exists.
| Capability | Assistant Cortex | Base44 |
|---|---|---|
| Prompt-to-app building | Yes — the Coding Sandbox builds, tests and publishes modules into your marketplace | Yes — generates standalone apps with hosting, database and auth built in |
| 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 | Email-sending integration; no agent-managed mailboxes |
| Module marketplace | Yes — applications and AI abilities install with a click | No — each generated app is its own standalone product |
| AI model choice | 80+ preconfigured models across 15 types; custom models supported | Uses the platform’s built-in model integrations |
| Team governance | User groups and per-application ACL permissions shared across every module | Role-based permissions inside each generated app |
| MCP support | MCP native — a built-in MCP client and server; abilities are published as MCP tools | Not documented |

The same prompt-to-app workflow — watched, tested and approved
Assistant Cortex builds applications the way Base44 does: you write a short brief, a coding agent does the work. The difference is what surrounds the build. Every project runs on an isolated sandbox, is tested against the live platform, and only reaches your marketplace when you approve it.
- A project, not a chat. Each build is a project you can watch, stop, modify and re-run from a dashboard.
- Tested against the real thing. The sandbox runs your module against a live copy of the platform before you ever see it.
- Published on approval. Nothing lands in your marketplace until you say so — and once it does, it installs like any other application.
- Real results. A notes app, a 3D Rubik’s cube solver, an interactive chat card and a telnet server — four working modules from four short briefs.
The part no app builder ships: agents on the phone
An app builder gives you screens. Assistant Cortex also gives you the workforce: agents that answer inbound calls on a real number, place outbound calls with an instruction, hand a caller to a human when it matters, and file the recording, the transcript and the reasoning trace afterwards.
- Provision numbers inside the app and point each one at an agent.
- Every call explained — recording, speaker-separated transcript, and the agent’s reasoning at each step.
- The same agents answer SMS and email, so one workforce covers every channel.
Which should you choose?
Choose Base44 when…
- You need one standalone app — an internal tool, a form, an MVP — and nothing around it.
- The fewest possible decisions matters more than control over models, permissions or data.
- You are already in the Wix ecosystem and want to stay there.
Choose Assistant Cortex when…
- You want AI agents doing real work — answering the phone, working mailboxes, moving a sales pipeline — not only an app.
- New apps should join the platform you already run, under the same users, groups and permissions.
- You want to choose the AI models behind everything, including your own.
Frequently asked questions
Is Assistant Cortex a direct replacement for Base44?
For app building, yes — you describe the application in plain language and the platform builds it. But the two products end in different places: Base44 produces a standalone app, while Assistant Cortex produces a module inside a platform that also runs AI phone, email and sales agents under shared permissions.
Does Base44 have AI phone agents?
No. Base44’s Superagents run background tasks, but the product does not offer AI agents that answer or place real phone calls. Assistant Cortex agents work real phone numbers, with recordings, speaker-separated transcripts and reasoning traces for every call.
Can Assistant Cortex build an app from a prompt the way Base44 does?
Yes. You write a short brief the way you would hand a ticket to a developer. The Coding Sandbox builds the module on an isolated sandbox, tests it against the live platform, and publishes it to your marketplace when you approve it — every build is a project you can watch, stop and modify.
Can I choose which AI models Assistant Cortex uses?
Yes. Assistant Cortex ships with more than 80 preconfigured AI models across 15 model types — language, image, audio, speech, embeddings and more — and custom models can be added, so you decide what powers each agent and application.
How does Assistant Cortex compare to Lovable or Lindy?
Lovable is an app builder like Base44, strongest at full-stack MVPs you export as code; Lindy is an AI-employee platform without app building. Assistant Cortex covers both jobs. See the Lovable comparison and the Lindy comparison.
