Tierpik is a free, read-only information service that suggests which AI model, setting and app to use for a task. Recommendations are general guidance based on publicly available information about AI products as of the date shown in each answer. AI vendors change plans, models and limits often; always confirm in the vendor's own app.
The service is provided "as is" without warranties of any kind. Tierpik is not affiliated with OpenAI, Anthropic, Google, xAI, Perplexity or Microsoft; their names are used only to identify their products.
To the extent permitted by law, Tierpik is not liable for any loss arising from use of the service, including usage charges or limits incurred in third-party AI products.
Don't attempt to disrupt the service, overload it with automated traffic, or use it unlawfully. We may rate-limit or block abusive traffic.
We may update these terms; continued use after changes means you accept them.
These terms are governed by the laws of India.
