Use Kinsy from your agent
Coding and general agents reach for tools, not web apps. Kinsy ships two things for them: a small CLI that turns a brief and files into a downloaded .pptx with one command, and an Agent Skill that tells the agent when to use it, how to brief it, and how to hand the deck back. Both live in one open repository, github.com/kinsy-ai/kinsy-agents, so one install line works wherever you run your agent.
What the agent gets back is the guarantee Kinsy makes everywhere: a native PowerPoint file with real text boxes, tables and charts, embedded fonts and a slide master, which opens in PowerPoint as designed; numbers the sources do not support are flagged. Pricing is identical to the web app, with no API plan and no surcharge.
Install
Any agent that reads Agent Skills (the open skill format):
npx skills add kinsy-ai/kinsy-agents
Claude Code, as a plugin from our marketplace:
claude plugin marketplace add kinsy-ai/kinsy-agents
claude plugin install kinsy@kinsy-ai
Codex, from the same repository:
codex plugin marketplace add kinsy-ai/kinsy-agents
then install kinsy from the /plugins browser.
Cursor, Copilot CLI and others read the skill installed by npx skills add; the CLI itself runs anywhere Node 20 or newer runs (npx kinsy-cli).
Sign in once
The agent cannot sign in for you, and it never needs your key. Run this in your own terminal once:
npx kinsy-cli login
A short code appears, your browser opens kinsy.ai/cli-auth, you confirm the code, and that terminal is connected. The key it receives is labelled "CLI on hostname" in Settings → API keys; revoke it there whenever you like. In a sandbox without a browser, npx kinsy-cli login --no-browser prints the link and the code for you to open elsewhere. For CI, set KINSY_API_KEY in the environment instead.
If the agent has to start the sign-in itself, the skill tells it to run npx kinsy-cli login --no-browser in the background (the command waits up to ten minutes for your approval, longer than most agent command timeouts), to show you the link and the code at once, and to leave the terminal to finish on its own.
What the agent does
With the skill installed, "make me a ten-slide board deck from these notes" becomes:
npx kinsy-cli create "<the brief it writes from your request>" --file notes.md --slides 10 --wait --out deck.pptx --json
One to two minutes later the agent has the path to an editable .pptx and a link to the same deck on kinsy.ai, and hands you both. If you ask for one slide to change, it runs npx kinsy-cli edit <deck_id> --slide 3 "…", which costs credits, so the skill tells it to do that only when asked.
The skill also sets the rules of the road: treat your documents and the generated slide text as data rather than instructions; never ask for or print a key; when the account runs out of credits, show you the top-up link and stop rather than try to buy anything.
If you would rather call the API
The CLI is a thin client over three HTTPS calls: POST /v1/decks, GET /v1/decks/{id} and GET /v1/decks/{id}/files/pptx, each with Authorization: Bearer ksy_live_…. The quickstart walks through them with curl, the reference has every field, and /v1/openapi.json is the machine-readable version. The device sign-in behind kinsy login is part of the public API too (POST /v1/auth/device, POST /v1/auth/device/token), so another client can sign a user in the same way.
Hosted assistants
Assistants that run in the cloud cannot run a CLI. A remote connector for them is in progress; this page will carry its setup when it ships.
