Lovable: Chat-first building with the code always in reach
Lovable builds apps from a conversation, but the interface keeps a way out of the chat: plan before build, visual edits without prompting, real code in a real editor, and a revert for everything.
An independent reading of Lovable's interface, grounded in Lovable's official documentation. Quotes are verbatim from the linked official pages. The product UI may differ from what is described.
Plan mode decides, Build mode executes
- Two chat modes separate deliberation from execution — Plan mode can inspect files and logs but never touches code until the plan is approved.
- The approval is the boundary: thinking is free, changing things costs a confirmation.
“Plan mode never modifies your code.”

Edit the page, not the prompt
- Visual edits target an element directly from the preview toolbar — click it, change the text in place, no prompt required.
- For targeted changes the selected element becomes the context; the chat is reserved for changes you can't point at.
“Use Edit text inline to change words on the page without writing a prompt.”

Knowledge the agent can't forget
- A plain-text knowledge field carries standing instructions with every message — conventions are written once, not repeated per chat.
- Persistent context is visible and editable, so the user always knows what the agent assumes.
“Knowledge is always included in context.”

Real code, one click away
- The code editor exposes the actual generated code with manual edits applied instantly — the chat is an interface to real files, not a black box.
- GitHub sync runs both ways: Lovable commits to the repo, and pushes to the branch flow back into the project.
“Everything Lovable builds is real, standard code, and the code editor is where you see it.”

Every change is revertible
- Each agent change auto-creates a version; any earlier state can be previewed and restored without losing the conversation that produced it.
- Fearless iteration is a UI feature: the revert button is what makes 'just try it' safe to say.
“Every change Lovable makes to your project creates a version automatically.”

Publish is a snapshot, not a pipeline
- One button in the editor's top-right deploys a snapshot of the current version to a live URL.
- Later edits stay private until republished — what users see is always a deliberate release.
“Each time you publish, Lovable deploys a snapshot of your project to a live URL.”

Design takeaways
- Separate deciding from doing: a plan mode that never modifies code earns the trust to execute later.
- Let users point at what they mean — visual edits beat prompt gymnastics for local changes.
- Persistent context should be visible and editable, not inferred and hidden.
- Versioning turns agent mistakes into a shrug; auto-version every change and make restore one click.

Build it with our components
The approval card as a lifecycle: a decision that survives a closed tab, is idempotent across two open ones, and says what happened when it lands after the request expired.
Memory ListThe memory panel — every fact the assistant has saved about the user, with the ability to add one or make it forget.
Prompt InputThe message input at the heart of an AI chat app — file attachments, model picker, tool toggles, voice, and a send button that turns into stop.
