Artificial Intelligence

Unleash creativity Unlock intelligence

Your potential is currently hindered by:

  • Unwieldy chat interfaces with assistant personas
  • Prompts that don't adapt to the edits you make to their outputs
  • Settings that can only be changed by developers, but dialed to general, cost-saving levels in consumer apps
  • Apps that make creating, running, and saving prompts and their outputs difficult

Promethic is a prompt manager that creates, customizes, runs, and refines your prompts based on your usage.

Free with your own API key. No subscription required.

Versioned Prompts

A prompt manager with versioned prompts. No more retyping, copying and pasting, or clicking through menus to find your prompts.

Dialed-in Settings

Set model, reasoning effort, verbosity, image output dimensions, and other settings only available to developers. Settings are set per prompt, per version.

Run & Revise Loop

Prompts run directly. Ask for a revision, or edit the output. These changes are automatically stored so Promethic can refine your prompt for you.

Text, Image, and JSON Output

Supporting all of your needs, from productivity to creativity. Attach text or images to be sent automatically for every conversion.

Generate New Prompts Effortlessly

Give Promethic real examples of the output you want, and let it create a skillful prompt including those examples. Need help with that? Submit messy unstructured data, and Promethic will parse out examples, creating synthetic inputs if needed.

Own Your Data

Each prompt keeps records of all conversions you end up copying or downloading. Use this database to create more powerful prompts, to fine-tune future models, or build your portfolio.

No more conversations. Input in, output out.

Conversations make for an easy on ramp, but don't work well for tasks you repeat often. Copy or paste your input, and click convert. If the output needs work, ask Promethic for a revision or make the edits yourself. When you copy the output, this tells Promethic you got your desired result. Other interfaces have no idea whether you got there, or whether you gave up trying. Any revisions or edits you made along the way get saved automatically as a Delta. These accumulate as signals for this version so that Promethic can know how to refine your prompt.

Refine prompts based on the edits you make.

After using a prompt for a while, Promethic will automatically track changes you've had to make to the output. Have Promethic refine a prompt, and it will analyze the current version along with the Deltas it has tracked, and propose a new version which incorporates real examples from your actual usage. Review the diffed changes and request a revision, or accept it as a new version. Enjoy creating with fewer corrections. Roll back at any time.

Settings dialed in per prompt.

Every prompt version carries its own model, reasoning effort, verbosity, or whatever other parameters that model allows you to set. Switch models, or switch output type from text to image, and the available settings you can set appear, ready for you to dial them in.

Image generation? Same workflow.

Create a prompt, select image output, optionally attach an image for reference, and dial in resolution, format, quality, and other settings you couldn't access before. If an image isn't quite right, request a revision just like you would with a text prompt.

We exist to bring form to platonic ideals, building tools so we can co-create with our users.

Promethic exists because we needed it ourselves. We wanted to distill our creativity, our essence, our vibes into workflows that would allow us to dream bigger and build more. We wanted to put the effort to work that we were spending on refining outputs from generalist chatbot interfaces.

We recognize that we exist to serve our users. If our ethos and our products resonate with you, please support us, and share with others so we can build a more beautiful future.

Your prompts should evolve, not reset.

Every change you make is data that belongs in a feedback loop. Start creating with Promethic.
