Learn about the original Promptheus push-to-talk extension, its exact identity, historical free launch and current compatibility and pricing limits.

Updated October 28, 2026

Name	Promptheus
Overview	Promptheus is Doug Silkstone’s voice-to-ChatGPT Chrome extension, identified here by extension ID eipjdkbchadnamipponehljdnflolfki. Its maker’s original launch describes push-to-talk voice input using the spacebar and the browser’s speech-recognition API. Current store availability and compatibility could not be confirmed from the exact listing.
Key features & benefits	Speak a prompt instead of typing using the original push-to-talk workflow. Open ChatGPT through the extension button, as described at launch. Language settings were part of the earlier product description; current language coverage is unverified.
Use cases and applications	Dictate a question or rough draft for later review. Reduce typing where voice input is appropriate. Check the transcription before sending; the original spacebar workflow is not fully hands-free.
Who uses?	People who prefer dictating prompts, subject to current browser, microphone and service compatibility.
Pricing	The maker’s original launch listed Promptheus as free. No current premium subscription or paid feature pricing was verified, so the earlier subscription claim should not be relied on.
Tags	Voice Input, ChatGPT, Chrome Extension, Dictation
App available?	Originally a Chrome extension. The exact store URL returned an empty listing shell during retrieval; current installation availability was not confirmed.

Availability and limitations

The feature description is historical, not a live compatibility test. No extension was installed, microphone permission granted or speech recorded. Verify the exact publisher and listing before using software with microphone or page access. A similarly named prompt-engineering tool is not evidence of a replacement for this extension.

Practical example

Hypothetical editorial example: dictate a non-sensitive question about a book, then inspect the transcription for names and punctuation before sending it. This is a possible use case, not a tested recognition or response-speed result.
