How it works

Lindi lifts the design out of your app.
Design edits can’t touch the logic. Developers can.

Bring the product you already ship. Designers and builders rework the design layer while your logic stays out of their reach — and developers get the whole codebase, front end to back end. Everything merges back as clean changes your team can review.

§ 01 · extractiondesign edits can never touch your logic. developers can edit everything.

Bring your app, lift the design out, rework it, merge it back.

That's the whole flow, in the order it happens. Your business logic sits there through all four steps — not one design edit touches it, and your developers can still work on every line.


FIG 1 — the layer stack: the design lifts off the top; the code underneath is safe from design edits, and developers can still work on all of it.

Bring the product you already run.

Point Lindi at the live product — the screens, the styles, the flows, the repo behind them. It reads everything and writes nothing.

STEP 01/04 — Lindi reads your product where it lives, and writes nothing

source: the product you run
read: screens · styles · flows
written: nothing

Lift the design layer out.

Every screen, style and interaction becomes editable on the canvas. Design work can’t touch the code underneath — and your developers can still edit every line of it, back end included.

STEP 02/04 — the design comes out, the logic stays put
After the lift
design layer — editable, on the canvas
code & logic — untouched by design edits

Rework it with the agent.

The agent proposes structured edits — each one named, scoped to the design layer, and reversible. You keep the ones you like and undo the ones you don't, one decision at a time.

STEP 03/04 — each edit is one decision: keep it or undo it
Structured edits
edit 01 · header — kept
edit 02 · spacing — kept
edit 03 · type scale — undone
keepundo

Merge it back as one change.

The rework lands in your own repo as a single branch — reviewable line by line, like any change your team ships. Nothing else moves.

STEP 04/04 — one branch lands in your repo, ready for review

§ 02 · the kit

Eleven capabilities ship with Lindi.
You own every one of them.

Here's the full kit, exactly as it ships. Each capability is its own module you can switch on or off — try the live configurator on the homepage.

The agent only ever edits the design layer — it never even sees your business logic.
§ 03 · builder mode

Describe a change in a sentence.
Watch the preview make it.

Builder mode is for the people on your team who don't design or code. There's no toolbar to learn — you describe the change in plain language and the live preview makes it in front of you. Designers and developers stay in the same file the whole time.
