Cartesia Prompts
Cartesia is a real-time voice AI company whose Sonic model delivers ultra-low-latency text-to-speech for voice agents. It is purpose-built for real-time, sub-second synthesis as infrastructure, prioritizing speed for live voice agents over content tooling.

What are cartesia prompts?
cartesia prompts are engineered instructions that already work, written and tested for Cartesia. These are not one-line questions. Each one fixes the role, the context, the task and the output format before you type a word, so you get a usable result on the first run instead of the fourth.
They cover the work that actually fills a week: research, briefs, copy, content, analysis, reporting, planning and outreach. Open a card to see the full prompt and the output it returns.
Free to read, free to copy.
Why these prompts beat writing your own
A weak prompt costs you the hour you were trying to save: you rewrite it three times, get something generic, then finish the job by hand. An engineered prompt front-loads that thinking once.
That means first drafts you can send, analysis you can act on, and the repetitive work handed off, so the time goes into judgement instead of typing.
Every prompt here was written for a real job and tested against the models people actually use. Nothing scraped from a thread.
How to use these prompts in Cartesia
Open a prompt, copy it, and replace the [bracketed] variables with your own product, audience or topic. The structure around them stays as is. That structure is the part doing the work.
Paste it into Cartesia and run. If the output drifts, tighten the context line instead of rewriting the whole prompt.
No account needed to copy one. No setup, no extension, nothing to install.
Do these prompts only work with Cartesia?
They are tuned for Cartesia, but the skeleton of role, context, task and format carries over to any capable model. Swap model-specific settings like tone or length when you move.
Are these AI prompts free to use?
A big part of the library is free: open a prompt, copy it, use it. Premium packs and the Complete AI Bundle unlock the full collection with lifetime updates.
How do I adapt these prompts to my use case?
Start with the [variables]: niche, audience, constraints. If the result still misses, add one example of the output you want. A single good example beats three extra instructions.
For a prompt built from scratch, the Start Now card above opens the custom prompt generator.

How to use Cartesia
Create an account and call the Sonic model through the API, or test it in the playground, with your text and a chosen voice. It is billed per character, so estimate cost from your output volume. It suits being embedded in a voice-agent stack rather than one-off content.

Low-latency, real-time speech for conversational voice agents. Streaming synthesis where response time is critical. Developer and API-first voice infrastructure.
Pricing
Free tier with a monthly allowance for non-commercial use. Paid tiers scale up to a few hundred dollars a month, working out to roughly $5 to $37 per million characters.
