| What's free | 25,000 conversions/month (Engine 1 & 2) plus 1,000 Engine 3 conversions/month; max 1 MB file, PDFs up to 3 pages | 10M free tokens (one-time) across all models — embeddings, rerankers, classifier; plus a keyless Reader (r.jina.ai) for basic use |
| Rate limits | 500 requests per day per IP address | Free key: 100 RPM / 100k TPM for embeddings & reranker; Reader 20 RPM keyless, 500 RPM with a free key |
| Expires | no expiry | no expiry |
| The catch | Free searchable-PDF output carries a watermark (raw text extraction is unrestricted); the free key needs only an email, no card. Commercial use permitted. | The 10M-token balance is a one-time grant that does not replenish; the keyless Reader is genuinely ongoing. Hosted API is commercial-OK and data is not used for training. No card required. |
