What's the difference between these three tools?

They cover three different stages of the research-writing workflow. SciSpace is strongest at the literature-review stage — finding and comprehending papers. Jenni.ai is strongest at the drafting stage — writing your own prose with citation-aware autocomplete. Paperpal is strongest at the pre-submission stage — polishing language and checking journal-compliance requirements before you submit.

Can I use more than one?

Many researchers do, precisely because they cover different stages: SciSpace for literature review, Jenni.ai (or your own drafting) for the manuscript itself, and Paperpal for a final submission-readiness pass. They're not mutually exclusive — think of them as a pipeline rather than three competitors for the same job.

All three offer usable free tiers. For paid plans: SciSpace Premium is $12/mo, Jenni.ai Unlimited is $12/mo (billed annually), and Paperpal Prime starts around $11.58/mo (billed annually) — very close to each other, so pick based on which stage of the workflow you need help with, not price alone.

Do any of these replace a human copyeditor?

No. All three speed up drafting, review, or formatting, but none replace a substantive human read for argument quality, discipline-specific nuance, or a native-level command of academic register that a good copyeditor or advisor provides.
