ErrorDost – Explain Errors in Urdu, Hindi, Arabic & English

Got an error you don't understand? One click, and ErrorDost explains it in your language.

ErrorDost turns confusing compiler, linter and runtime errors into a short, friendly explanation in English, Urdu (اردو), Roman Urdu, Hindi (हिन्दी) or Arabic (العربية):

• Meaning: what the error is saying, in plain words
• Why it happened: the most likely cause in your code
• How to fix it: concrete steps, plus a small before/after code example

Common errors are explained instantly and offline from a built-in knowledge base, no AI needed. For everything else ErrorDost uses the AI you already have (GitHub Copilot, Claude Code, Ollama, or your own Claude / OpenAI / Gemini key). No account, no server, no cost.

Made for students, bootcamp learners and anyone who'd rather read an error explanation in their mother tongue. Pro mode gives experienced developers short, technical answers.

Three ways to explain an error

1. 💡 In the editor: put the cursor on a red or yellow squiggle and click the lightbulb (Ctrl+. / Cmd+.) → Explain this error with ErrorDost. You can also hover over the error and click Explain with ErrorDost.
2. In the terminal: when a command fails (npm run build, python app.py, javac Main.java, …), ErrorDost offers to explain the error output. Needs VS Code's terminal shell integration, which is on by default.
3. Any error text: select an error message or stack trace in any editor → right-click → ErrorDost: Explain Selected Error. Or run ErrorDost: Explain an Error (paste) and paste text from the browser console, a CI log or anywhere else. (You can also right-click in the terminal to reach this command.)

Languages

On first run ErrorDost asks which language you want. Change it any time with ErrorDost: Choose Explanation Language or the errordost.language setting. Urdu and Arabic are shown right-to-left, and Urdu uses a Nastaliq font.

Here is the same error in all five languages:

TypeError: Cannot read properties of undefined (reading 'name')

English

Meaning: You tried to read .name from something that is undefined, meaning it has no value yet. Why: The variable before .name was never set, or the data (e.g. from an API) hasn't arrived yet. Fix: Check that the value exists first, e.g. user?.name, or make sure it is assigned before this line.

اردو (Urdu)

مطلب: آپ نے کسی ایسی چیز سے .name پڑھنے کی کوشش کی جو undefined ہے، یعنی اس میں ابھی کوئی قدر (value) نہیں ہے۔ وجہ: .name سے پہلے والا ویری ایبل کبھی سیٹ نہیں ہوا، یا ڈیٹا (مثلاً API سے) ابھی تک نہیں آیا۔ حل: پہلے چیک کریں کہ قدر موجود ہے، مثلاً user?.name، یا یقینی بنائیں کہ اس لائن سے پہلے اسے ویلیو دی گئی ہو۔

Roman Urdu

Matlab: Aap ne .name aisi cheez se parhne ki koshish ki jo undefined hai, yani us mein abhi koi value nahi hai. Wajah: .name se pehle wala variable kabhi set nahi hua, ya data (maslan API se) abhi tak nahi aaya. Hal: Pehle check karein ke value maujood hai, jaise user?.name, ya yaqeeni banayein ke is line se pehle us ko value di gayi ho.

हिन्दी (Hindi)

मतलब: आपने किसी ऐसी चीज़ से .name पढ़ने की कोशिश की जो undefined है, यानी उसमें अभी कोई value नहीं है। वजह: .name से पहले वाला variable कभी set नहीं हुआ, या डेटा (जैसे API से) अभी तक नहीं आया। हल: पहले जाँचें कि value मौजूद है, जैसे user?.name, या पक्का करें कि इस लाइन से पहले उसे value दी गई हो।

العربية (Arabic)

المعنى: حاولت قراءة .name من شيء قيمته undefined، أي أنه لا يحتوي على قيمة بعد. السبب: المتغير الذي قبل .name لم يتم تعيينه، أو أن البيانات (مثلاً من API) لم تصل بعد. الحل: تحقّق أولاً من وجود القيمة، مثل user?.name، أو تأكد من تعيينها قبل هذا السطر.

Choose beginner (default: simple words, step by step) or pro (short and technical) with errordost.level.

Supported programming languages

Errors from any other language still work through AI.

No AI needed for common errors

ErrorDost ships with an offline knowledge base of the most common beginner errors, written in all five languages. When your error matches, the explanation appears instantly, offline and free. A button lets you ask AI for an explanation tailored to your exact code.

Turn off errordost.knowledgeBaseFirst if you always want an AI answer first.

AI setup (optional)

With the default errordost.aiProvider: auto, ErrorDost uses the first one available: GitHub Copilot → Claude Code → Ollama → an API key you saved. Most people need no setup at all.

API keys are stored in VS Code's encrypted Secret Storage, never in settings files. Use errordost.model to override a provider's default model.

Privacy

• Only the error is sent. The AI receives the error message and a few lines of code around it, never your whole file or project.
• Secrets are stripped first. Those few lines are sanitized before sending: things that look like API keys, tokens, passwords and connection strings are masked.
• Your own AI. Requests go straight from VS Code to the provider you chose. ErrorDost has no server, no telemetry and no account.
• Offline mode. Set errordost.aiProvider to none and nothing leaves your machine.
• Explanations are cached locally so the same error isn't sent twice. Clear the cache with ErrorDost: Clear Explanation Cache.

Commands

Settings

Requirements

• VS Code 1.93 or newer.
• For AI explanations: one of GitHub Copilot, Claude Code, Ollama, or an API key. Common errors work without any of them.
