How Credits Work

Discover how credits work and how they provide flexible access to our powerful AI tools.

What are Credits?

Credits used for features like Translation, Transcription, and Context Extraction. Using these features will deduct credits from your balance. See "Credit Usage" below for details.

You can receive credits by purchasing credit packs as needed.

Where Can I See My Credits?

You can see your remaining credit balance and usage history in User Information page.

Which Models Should I Use?

Different LLMs (Large Language Models) have varying performance when it comes to different languages and tasks.

For example, DeepSeek models excel at English and Chinese (surprisingly good at Indonesian too) but may struggle with other languages, while some models like Gemini and Claude are multilingual and perform well across many languages.

It's important to experiment with different models to find the best fit for your specific language and use case.

Tips:
  • Start with cost-effective models (like Gemini 2.0 Flash / Qwen3 235B / GPT-4.1 mini).
  • If the results meet your needs, you can continue using them.
  • If you need higher quality results, you can gradually switch to more expensive models.

Generally, Gemini 2.5 Pro, GPT 4.1, and Claude Sonnet provide excellent results for most use cases and languages.

Credit Usage

Credit costs vary based on the specific AI model used. Costs are typically calculated based on the number of input and output tokens processed. More models will be added in the future. See the estimated costs below.

* These are estimated costs and limits, and are subject to change. Input/Output token costs may vary. Refer to the dashboard for precise figures.

Token: A unit of text processed by the LLM. Roughly 4 characters or 0.75 words.

Context Length: The maximum number of tokens (input + output history) the model can consider at once.

Max Completion: The maximum number of tokens the model can generate in a single response.

Transcription (Experimental)

Transcription tasks consume credits based on the duration of the audio processed. The credit cost differs when the audio is less than 100 minutes compared to when it is more than 100 minutes. Yes, you can split your audio first for better pricing.

Background Processing (Soon)

Background processing allows certain tasks, like audio transcriptions, to run on our servers even if you close the browser tab.
This means you don't have to wait for the process to finish. This feature will be available soon.
