😂 Meme Generator

Turn a photo - or an instant AI image - into a meme with top and bottom captions

About this tool

Turn any picture into a ready-to-share meme. Upload your own image, or generate one instantly from a text prompt with the AI image generator - then add a top caption, a bottom caption, or both. The picture stays whole: each caption is added as a clean bar above or below it (no text means no bar), and the canvas grows to fit, so nothing is cropped or covered. Pick the bar and text colours (a black bar with white text by default), then play with the post-production controls - a colour grade plus saturation, brightness, contrast, temperature and hue - to make it pop. Free, no signup, no watermark.

Upload a photo, or type a prompt and hit Generate for an instant AI image.

API

POST /api/tools/meme-generator/run (multipart/form-data) → JSON with outputs[].url, a zip link and a config_url.

Every run also hands you the config JSON (button above). It is the request body - POST it straight back to replay the exact generation:

curl -X POST -H 'Content-Type: application/json' \\
  --data @genbox-config-meme-generator.json \\
  /api/tools/meme-generator/run

Call it from an agent

GET /api/tools/meme-generator - machine-readable spec of this tool (inputs, category, API block).
GET /api/tools - list of every tool plus the categories.
POST /api/tools/meme-generator/run - run it. Accepts multipart/form-data (with files) or a raw application/json body. Returns JSON with outputs[].url, zip and config_url.
The config_url JSON is the request body - POST it back to replay the same generation.

  -H 'Content-Type: application/json' \\
  --data @genbox-config-meme-generator.json

Rate limits

Max 1 request per minute per IP on the run endpoint.
Over the limit you get HTTP 429 with retry_after (seconds) - wait that long and retry.
Higher limits and API keys are coming soon: an API key will lift the per-IP throttle. Not available yet.
