About

Open Grok on the web or phone to ask questions, draft text, and explore topics. Teams and developers use the API for fast multilingual chat, speech-to-text/text-to-speech, and video generation. Heavy users can opt into SuperGrok Heavy for access to Grok Heavy and much higher rate limits.

Try It Like This

1
Draft social posts on your phone
Sign in to Grok on the iOS or Android app → paste a short brief (audience, tone, length) and ask Grok to draft 3 caption options → copy the best one and schedule or post. The first 'wow' moment: see multiple ready-to-post variants tailored to your brief within seconds.
2
Transcribe and reply to a call
Record or stream the call audio to Grok's Voice API → receive a fast transcript and ask Grok to draft a concise reply or follow-up email → send the suggested reply after quick edits. The first 'wow' moment: get a near-instant transcript you can search and use to create next steps.
3
Prototype a short ad video
Post a text prompt to the Imagine API specifying length, style, and quality → review the generated short clip and request a variant with different pacing or voiceover → iterate until the clip matches the concept. The first 'wow' moment: receive a playable draft clip tuned for your chosen tradeoff (quality, cost, or latency).
4
Quickly summarize trending info
Open a chat and paste links or short excerpts from current posts → ask Grok to summarize key points and list sources or timestamps → use the summary to create a short update or briefing. The first 'wow' moment: a concise, sourced summary of current material ready for sharing.
5
Add AI features to an app (non-developer preview)
Read the Developer Docs linked in Grok's product page to see sample requests and endpoints → try an example curl or Postman request provided in docs to call the Voice or Imagine API → evaluate response times and outputs to decide if you’ll integrate the API. The first 'wow' moment: a sample API response that produces usable text, audio, or video without building full infrastructure.
