Frequently asked questions

Can I cancel Pro anytime?▾

Yes. Cancel anytime from your dashboard. You'll keep Pro access until the end of your billing period.

What happens when I hit 5 AI analysis on Free?▾

You can still browse papers, read existing summaries, and participate in discussions. You just can't generate new AI analysis until the next month — or you can upgrade to Pro for unlimited.

Is Annotia only for academics?▾

Not at all. Annotia is for anyone who wants to engage with research — clinicians, students, journalists, curious minds. The AI analysis are specifically designed to make papers accessible to non-specialists.

What papers can I access?▾

We index over 250 million open access papers from OpenAlex and Semantic Scholar. We only surface freely available research — no paywalled content, ever.

Will there be a team/institutional plan?▾

We're exploring this. If your institution is interested, reach out and we'll prioritise it.
