Pricing Model
Difference
PaidSciSpace uses a subscription-plus-credits model. The official pricing page we could read showed the plan headline and a 24-hour money-back guarantee but not the dollar amounts, so the figures below come from a third-party tracker (CostBench, last verified October 2026) and should be confirmed on scispace.com/pricing before you buy. That tracker reports no permanent free tier or trial. Reported paid tiers: Premium at $20/month or about $12/month billed annually ($144/year); Advanced at $90/month or about $70/month annually ($840/year); and Max at $200/month or about $160/month annually ($1,920/year). Annual billing is said to save roughly 20 to 40 percent depending on tier. Enterprise pricing is custom. Usage is credit-based and monthly credits do not roll over; add-on credits and services such as English editing or journal submission cost extra. Several user reviews describe credits running out faster than expected, so starting monthly before committing to an annual plan is sensible.
FreemiumScite offers a free plan with limited Smart Citations per month and basic search features \u2014 sufficient for occasional research needs. The Personal plan unlocks unlimited Smart Citations, full-text search, dashboards, contextual citation reports, the Scite Assistant AI, and custom alerts at $20/month (monthly) or $12/month billed annually ($144/year). A 7-day free trial is available for new users. Organization and Developer plans require custom pricing through Scite\u2019s sales team and add upgraded AI models, expanded assistant capabilities, expanded search analysis, shared dashboards, expanded data exports, 24/7 dedicated support, API access, and SSO/SAML for institutions. Important: Multiple users have reported auto-billing without advance notification. Monitor your subscription renewal dates carefully and cancel before trial expiry if not proceeding to paid.
