Every plan gets

The same engine. The same citations.

Amass *Core is the product. Plans differ on reports, usage, seats, and support — never on data quality.

All 8 data cores
Biomed · Trial · Drug · Regulatory · Gene · Patent. Every plan, every seat.
Cited to source
Every claim ties back to a DOI, NCT, patent, or URL. No paraphrasing.
The working trace
See every layer it searched and the terms it used — and what it read but didn't cite.
Fair use*
Use Amass the way real research works. Abuse gets a conversation, not a lockout.
MCP access
Connect Amass to Claude, ChatGPT, Cursor, or anywhere MCP is supported. Included on every plan.
EU-hosted
Azure EU regions. Your queries never train a model. ISO 27001 + SOC 2 controls.

* Fair use means practical limits that reflect how researchers actually work. We contact heavy users with a usage conversation, not a hard cut-off. Credit-based pricing is on the roadmap.

FAQ

Questions people actually ask.

Do I need a credit card to sign up for Free?

No. Free requires an account but not a card — and never converts to a paid plan automatically.

Is MCP available on the Free tier?

Yes. MCP is included on every plan, including Free. Connect Amass to Claude, ChatGPT, Cursor, or any MCP-compatible tool — no paid plan required.

What counts as a report?

A report is a full research run: Amass works through your question across the cores and returns a written synthesis with its citations and its working trace. Chat and MCP calls draw on your included usage allowance instead — the app shows your balance as you go.

What's the difference between Basic, Standard, and Business?

Basic and Standard are both single-seat plans. Basic includes 5 reports and a larger chat + MCP allowance than Free. Standard removes the report limit under fair use and carries our largest single-seat allowance — it's the plan for people running Amass daily. Business is up to 10 seats sharing a workspace, one pooled allowance, and priority support. Above 10 seats we move to Enterprise.

Can I switch plans later?

Yes. Upgrades apply immediately; downgrades apply at the next billing cycle. No contracts on Basic, Standard, or Business.

How does billing work for the Platform API?

The API is a separate product with usage-based pricing, billed monthly against your account. Same login, separate billing stream — so a Business subscription and an API subscription live side by side without double-charging.

I need custom agents or integrations built — can you help?

Yes. Amass Professional Services provides dedicated developer time to build custom agents, integrations, and workflows scoped to your team. Contact us to scope an engagement.

Do you offer academic or non-profit pricing?

Yes — email hello@amass.tech and we'll work something out.
