Plainly
Paste anything dense. Get it explained in plain English, side by side with the original.

How should Plainly explain your documents?

There is only one Plainly — this is a setting, not a different app, and you can change it any time from Settings. Nothing is uploaded anywhere until you choose a mode that needs it. New here? See how it actually works →
Advanced: use your own Anthropic API key instead → Advanced: use your own hosted proxy instead → Have a tester code? → Moving from another device? Restore a backup file first →
Or add files — drag them anywhere on this box
A scanned page or a photo of a document works too; it's read on this device.

Sign a document

This places a picture of your signature on a PDF — it does not verify identity and is not a certified e-signature. For many everyday documents that’s all that’s needed; where certified signing is required, use a qualified signing provider. The saved copy is a page-image PDF, made entirely on this device — nothing is uploaded.

1 · Your signature — draw it below, or (sign on plain paper, photograph it — the paper background is removed automatically; a clear, well-lit photo works best)
Saved on this device only, so it’s ready next time.
2 · The document —
A Word or other text file needs saving as a PDF first (File → Print → Save as PDF) — a signed copy must show the document exactly as it looks, and only a PDF or a photo carries the exact appearance.
