Compared a few options

Evaluated this against two competitors. Where it wins: citation generator and integrates with Word, Docs, and Chrome. Where it lags: output sometimes needs manual editing. On balance the feature set — especially text summarizer for articles and documents — justifies the 5 stars for our use case.

Use it every day

Honestly didn't expect to like it this much. Citation generator is exactly what I needed, and usable free tier for basic needs. I do wish word and character limits on free plan, but I reach for it almost every day now and it just clicks.

Ethan Brooks

Does the job

Pretty happy overall. Citation generator just works and multiple paraphrasing modes for varied tone. but no dealbreakers — I'd recommend it to a friend without hesitating.
