# Compare Noesis Plans: Origin, Synthesis, and Noesis Tiers

> Compare the three Noesis plans — free Origin, $11.99/mo Synthesis, and $23.99/mo Noesis — to find the right fit for your research workflow.

Noesis offers three plans designed to scale with the depth and intensity of your research workflow. **Origin** is free forever and gives you the full non-linear experience — branching, concept mapping, document uploads, and standard AI models. **Synthesis** unlocks premium models, real-time collaboration, and unlimited Spaces. **Noesis** is for power users who need maximum usage headroom, early access to experimental features, and priority support.

## Frequently Asked Questions

<Accordion title="Can I switch plans?">
  Yes. You can upgrade or downgrade your plan at any time from **Account Settings → Subscription**. Upgrades take effect immediately, giving you instant access to higher-tier features. Downgrades take effect at the end of your current billing period — you keep your existing tier's benefits until then.
</Accordion>

<Accordion title="What counts as usage?">
  Usage is based on the number of AI model tokens consumed across your conversations. Premium models — such as Claude Opus 4.8 and GPT 5.5 — consume tokens at a higher rate than standard models like Gemini 3.5 Flash or Claude Haiku 4.5. The Synthesis plan includes a meaningfully higher usage allowance than Origin, and the Noesis plan gives you 5× the usage of Synthesis, making it well suited for intensive, multi-branch research sessions.
</Accordion>

<Accordion title="Is there a free trial for paid plans?">
  There is no time-limited trial, but the **Origin free plan** is designed exactly for this purpose. It gives you full access to branching, concept mapping, document uploads, and standard AI models so you can thoroughly evaluate the Noesis experience before deciding to upgrade. We want you to be completely confident the product fits your workflow before you commit to a paid plan.
</Accordion>

<Accordion title="What payment methods do you accept?">
  Noesis accepts all major credit and debit cards, processed securely via **Stripe**. You'll be billed in USD at the start of each monthly billing cycle.
</Accordion>

<Accordion title="Do you offer refunds?">
  No. Due to the significant compute, API, and infrastructure costs involved in delivering real-time AI responses and branching context management, **Noesis does not offer refunds or credits** for any subscriptions or purchases. Payments for a billing cycle are final and non-refundable once processed.

  That said, when you cancel your subscription you retain full access to your paid plan's features through to the end of the current billing period — no access is cut off early. For full details, see the [Refund Policy](https://thinknoesis.xyz/refund).
</Accordion>

<Accordion title="Are prices in USD? Can I cancel anytime?">
  Yes, all prices are in USD. You can cancel your subscription at any time through **Account Settings → Subscription** — no hoops to jump through. Cancellation takes effect at the end of your current billing period, so you always get the full value of what you've paid for.
</Accordion>

<Note>
  All prices shown in USD. You can cancel at any time through your Account Settings.
