## Keep it, or make your own?

**Keep it.** The plain part of Originality.ai you could make: reports. What surrounds it you could not. The 4 things listed below take a company, not a weekend. It costs $155.40 a year.

- You could make: Reports: an app builder makes this well.
- You could not: Grammar checking as you type, wherever you type.
- You could not: It plugs into other products, Google Docs, Moodle and Google Classroom among them, and has an API.
- You could not: AI features, unless you pay a model provider for each request yourself.
- You could not: The depth: we grade its features B, which means it covers the whole job.
