On-device AI models
Run PDF AI on your own device
Check this device reports your browser’s support, memory and storage, and suggests a model: Gemma 4 E2B, about 2 GB, which works best with 8 GB of memory or more, or Qwen3 0.6B, about 600 MB, for machines with less. The voice and speech models used by the audio tools are managed here too. While you use a downloaded model, the AI tools work in this browser and don’t send your documents anywhere.
- Select Check this device.
- Select Download next to the suggested model and wait for it to finish.
- Open any AI tool, and come back here later to switch or delete models.
