Our take
Explain a private letter locally, and ask a person when the letter is a contract that matters.
Choose local if…
- The letter is personal or official
- You want a plain paraphrase
Choose cloud if…
- The contract is long and shareable
- You still plan to ask a professional

Questions
- Does this upload my files?
- The local tools on this page don't upload your files. The cloud options in the comparison do.
- What does it cost?
- Most options are free. A few apps are a one-time purchase, and a few models need a computer with more memory.
- What if it will not fit?
- Use Check my computer, or turn on the lighter memory filters. A red light on the model page means the file is too big.
