Keep Originality.ai, 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.
What you could make
- Reports: an app builder makes this well.
What you could not
- Grammar checking as you type, wherever you type.
- It plugs into other products, Google Docs, Moodle and Google Classroom among them, and has an API.
- AI features, unless you pay a model provider for each request yourself.
- The depth: we grade its features B, which means it covers the whole job.
What this rests on. Originality.ai’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
