One prompt.
Multiple image models.
One creative workspace.

Built for people who ship images, not one-off experiments
Reusable refined prompts
Describe an image once. Chall22 turns it into a refined, parameterized prompt with variables you can adjust and version — so good results are repeatable, not lucky.
Side-by-side provider comparison
Generate with OpenAI and Gemini from the same prompt and compare the results next to each other. Keep the one that fits; retry only what didn't. More providers coming soon.
One organized history
Every generation is recorded with the exact prompt and settings that produced it. Reopen any result, rerun it, or pick up where you left off.
A workflow, not a slot machine
Four steps that turn a description into results you can reproduce.
- 01
Describe
Start from a plain-language description of the image you need.
- 02
Refine
Chall22 rewrites it into a stronger, reusable prompt and identifies the variables worth changing.
- 03
Compare
Run the refined prompt on multiple providers at once and judge the results side by side.
- 04
Reuse & process
Save prompts, rerun past generations exactly, and send whole batches through the same pipeline.
Batches, handled end to end
The same care Chall22 puts into a single image applies to a hundred: upload a set, choose the operations, and let the batch run with full visibility — nothing silently dropped.
Background removal
Clean cut-outs across a whole folder of product shots in one job.
Renaming & optimization
Consistent file names and web-ready sizes, applied to every image in the batch.
Progress & ZIP downloads
Watch each item move through the pipeline, then download the finished set as a single ZIP.
Everything stays connected
Prompts, provider results, assets and history reference each other — so you can always answer “how did I make this?”
