IDE agent

You set the task, the agent does it in your project

No need to copy code into a chat and back. The agent opens the files it needs, writes the changes and shows them to you before saving to disk. All IDE features and screenshots

01

Reads the project itself

Opens files, searches the code and gathers context. You describe the task in plain words, like to a colleague.

02

Edits only with your approval

Every change is shown as a diff first. The file changes only after you click “Apply”, and the agent takes rejections into account too.

03

Runs commands

Tests, builds, package installs. Before running, you see the full command text and decide whether to execute it.

04

Any model

Claude, GPT, Gemini, Grok, DeepSeek, Kimi and GLM. Give hard tasks to a strong model and routine to a cheap one.

05

History for each project

Chats are stored separately for each folder and continue after a restart, along with drafts.

06

No prying eyes

Code goes only to the model you choose. The IDE collects no telemetry and doesn't load the editor from the internet.

FAQ

How do I pay?

By card in your profile, under “Balance & billing”. Tokens arrive on your balance right after payment, no subscription.

What are tokens and why do models cost differently?

Your balance is counted in base-rate tokens: 1M tokens costs $0.397. Stronger models are more expensive, so each of their tokens uses more balance tokens. Each model's price is listed in pricing, and the exact charge is shown under every answer in the chat.

Why are tokens cheaper than from the model developers?

We buy model access in bulk and sell tokens at a single price for input and output. For many models that's up to 10 times cheaper than the official rate; see the per-model comparison in pricing.

Do tokens expire?

No. Your balance stays on your account until you use it.

How is the IDE different from the chat?

The chat answers questions. The agent in the IDE works with your project files: it reads code, makes edits after you confirm them and runs commands.

Can I change the model's reasoning effort?

Yes. In the chat and the IDE there's a switch next to the input box: “Fast”, “Normal”, “Deep” and a maximum mode. In the IDE it's called “Ultracode”: the model reasons longer, the agent takes more steps and checks its edits with tests.

What do “Goal” and “Check for inconsistencies” do?

The “Check for inconsistencies” button is available in the chat and the IDE: the model rereads its answers and edits and looks for contradictions, errors and unverified claims without changing anything. The IDE has a “Goal” mode and a /goal command: the agent works on its own until it finishes the task and verifies the result with tests or a build.

Is there a referral program?

Yes. Your link is in your profile under “Invite friends”. Every time someone who signed up with it tops up by card, you get 10% of the top-up amount in tokens. More about the program.

How do I contact support?

Message us on Telegram: t.me/Sawasdee_krap. We'll help with payments, signing in, the IDE and API setup.

Can I connect my own app?

Yes. Create a key in the API tab and use the address https://slafy.co/v1. Any client that supports the OpenAI or Anthropic API will work.
