Karve AI · Coming soon

The API copilot that runs on your machine.

AI that generates requests, explains failures, and writes tests — running on local, on-device models, so your API data never leaves your PC.

Runs on-device · No cloud Built for Windows + NVIDIA RTX / DGX Spark

Ask in plain English

"Generate a request from this cURL" "Why is this returning 401?" "Write tests for this response"

API work is repetitive, fragmented, and often sensitive — yet the tools that speed it up want your endpoints and tokens in the cloud. Karve AI does the grunt work on your machine instead.

What Karve AI will do

Generate requests from a sentence — or a cURL.

Describe it in plain English, paste a cURL, or point at your docs — Karve AI writes a clean, runnable .http request you can send on the spot.

From cURL From docs Plain English

Create an order for SKU K-2049, qty 2…
generated.http
# @name createOrder
POST {{baseUrl}}/orders
Authorization: Bearer {{token}}
Content-Type: application/json

{
  "sku": "K-2049",
  "quantity": 2
}

Explain failed calls

Karve AI reads the status, headers, variables, request body, and response, then tells you what went wrong and how to fix it.

401 → "Your token variable is empty."

Suggest tests & assertions

From a real response, Karve AI proposes assertions worth keeping — status, shape, and the fields that actually matter.

expect status 200 · body.id is present

Extract variables & auth

Spot the host, tokens, and IDs repeated across requests and lift them into reusable variables and a clean auth pattern.

@baseUrl · {{token}} · @apiVersion

Generate docs & onboarding

Turn a working set of requests into readable API notes a teammate can follow on day one — straight from your real workflow.

Where it fits your day

Any dev

Debug a failing call in place

A 4xx you can't explain? Ask why — Karve AI points at the header, variable, or body that's off, without you leaving the workspace.

New joiner

Onboard to an unfamiliar API

Inherit a folder of requests with no context? Ask Karve AI what they do and how they fit together, and get oriented fast.

Sensitive work

Keep internal APIs internal

Working with private endpoints, tokens, or unreleased APIs? The AI runs locally, so none of that context is uploaded anywhere.

Local-first by design

Your API context is sensitive. It should stay yours.

Internal endpoints, tokens, private schemas, unreleased APIs — the things you debug daily are exactly what you can't paste into a cloud AI tool. Karve AI runs the model on your machine, built for the Windows AI PC era where NPUs and GPUs make on-device inference practical. AI help, without the upload.

The plan

Available today

Stage 1 — Local API workspace

The native Windows app that's already live: organize, run, and inspect .http requests locally.

Coming

Stage 2 — AI-assisted workflow

Generate requests, explain failures, suggest tests, and document APIs — the capabilities on this page, brought into the workspace.

The vision

Stage 3 — On-device copilot

A copilot tuned for Windows AI PCs and NVIDIA RTX / DGX Spark — local models doing the repetitive API work while your data stays put.

Karve AI

Karve AI is coming. The workspace it's built on is here today.

The AI features are in the works. The native, local-first Karve they're built on is already on the Microsoft Store — start there.
