Prompt input and token counting
Enter prompt text directly on the homepage to check token usage for the content you want to send to an OpenAI model.
Prompt Token Counter
Freemium
Check prompt token counts across supported OpenAI models before sending.
What is Prompt Token Counter?
Prompt Token Counter is a browser-based tool for checking how many tokens a prompt uses across supported OpenAI models. Its stated purpose is to help users make sure a prompt fits within the token limits of the model they plan to use.
The homepage provides a text area for prompt input, displays token counts for several OpenAI model families, and includes an explicit note that prompts are never stored or transmitted through the internet. The site also includes explanatory copy about token limits, prompt length, and why token counting matters when drafting requests for language models.
What can Prompt Token Counter do?
Model-specific token counts
The page shows token counts for multiple OpenAI model families and variants, including GPT-5, GPT-4.1, GPT-4.5 Research Preview, GPT-4o, and the o-series models listed on the page.
Privacy-focused prompt handling
A note on the homepage states that your prompt is never stored or transmitted through the internet.
Educational token guidance
The page includes explanatory guidance about what tokens are, what prompts are, and why token counting matters when working within model limits.
Optional prompt optimization service
The homepage promotes a professional prompt optimization service with consultation, prompt analysis, optimized prompts, documentation, a best-practices guide, three months of monitoring, and performance guarantees.
Use Cases
“Pre-flight prompt validation”
Check a draft prompt before sending it to an OpenAI model so you can trim or adjust text that would exceed the model’s token budget.
“Model selection support”
Estimate prompt size for different model families listed on the page, especially when comparing options with different token limits.
“Prompt refinement”
Review prompt length during prompt engineering work, where concise wording and token efficiency affect how a prompt performs.
“Onboarding and education”
Help new users understand how tokens relate to prompts and why token limits matter before they start using OpenAI models regularly.
Frequently Asked Questions
What does Prompt Token Counter do?
It is a web-based token counter for prompts used with OpenAI models. You paste or type prompt text into the page, and it shows token counts for supported models so you can check whether the prompt fits within a model’s limit.
Which OpenAI models does it support?
The homepage lists GPT-5, GPT-5 Mini, GPT-5 Nano, o4 Mini, o3, o1 Pro, GPT-4.1, GPT-4.1 Mini, GPT-4.1 Nano, GPT-4.5 Research Preview, GPT-4o, GPT-4o-mini, and GPT-4o as supported model families or variants, each with a displayed token count.
Does it store or transmit my prompt?
The page says your prompt is never stored or transmitted through the internet, which suggests the tool is designed for local, privacy-conscious prompt checking.
Is there pricing information on the site?
The site does not provide a documented pricing page; the `/pricing` URL returns a 404 page. Pricing details are therefore not available from the source pages reviewed.
