AI sources, limits, and allowance

AI generation uses its own weekly allowance. Review credits and AI allowance are separate: earning review credits from missions or ads does not replenish AI usage.

Supported sources

Use the camera or photo button for images, and the file button for supported documents or audio.

SourceSupported input
Written promptText entered in the composer
ImagesCamera capture or selected photos
Text files.txt and .csv
Audio files.mp3, .wav, and .m4a

PDF, DOCX, video, and direct website ingestion are not supported in this flow. For notes in another format, prepare a supported text file or a readable image first. A URL in a prompt is not a website-import feature.

Input limits

ItemLimit
Selected images5
Selected files2
Combined selected attachments20 MiB
Extracted text2 MiB
Prompt50,000 UTF-16 units, as counted by the app
Deck template1–20 fields
Cards in one generated result100

Requests that reuse earlier results can also include earlier attachments and card media. The app may report a limit that includes those sources. Prepared requests have additional limits of 20 images and 20 audio assets; reducing the number or size of sources can help when the prepared request is too large.

The composer displays validation errors before sending. Fix the displayed error; another one may appear after it is resolved. The send arrow remains unavailable while any input limit is exceeded.

Check your weekly allowance

  1. Open a deck's Generate with AI screen.
  2. Open AI Settings.
  3. Read AI Usage Limit for the percentage left and the reset date/time.

Flashnerd manages the AI service connection. There is no API-key or model-selection setup in the app. See Review and refine results for draft recovery and Troubleshooting permissions for device access.
