Every plan gets

The same engine on every plan

Every plan searches the same *Cores with the same engine. Plans differ on reports, usage, seats and support, and never on data quality.

All eight *Cores
All eight in the app, on every plan and every seat. The API and the MCP serve six of them.
Cited to source
Each claim carries its source: a DOI, NCT number, patent number or URL.
The working trace
Every *Core it searched, the terms it used, and what it read but didn't cite.
Fair use*
Unlimited reports on Standard and Business, under the fair-use note below.
MCP access
Connect Amass to Claude, ChatGPT, Claude Code, Codex or any MCP client, on every plan.
EU-hosted
Azure EU regions. Your queries never train a model. ISO 27001 + SOC 2 controls.

* Fair use covers unlimited reports. There is no hard cut-off: we contact heavy users to talk about their usage. Your usage allowance is a separate limit and pauses when it runs out (see the FAQ).

FAQ

Questions about plans and billing

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

No. Free needs an account but no card, and it never converts to a paid plan automatically.

Is MCP available on the Free tier?

Yes. MCP access is on every plan, Free included. Connect Amass to Claude, ChatGPT, Claude Code, Codex or any MCP client.

What counts as a report?

A report is a document Amass writes from a plan: in Build you review the sections, press Run plan, and get a report with numbered citations and its working trace. Answers in Ask and MCP calls are not reports. They draw on your usage allowance, and the app shows your balance.

What happens when I run out of my usage allowance?

Ask, Build and MCP calls pause until the allowance resets on your billing date, and reports pause with them, since each starts with a planning step that uses the allowance. On Standard, auto top-up under Settings › Subscription charges your saved card before you run out, at the amount, trigger and monthly cap you set. The monthly allowance is spent first; topped-up usage never expires. Fair use is a separate limit: it covers unlimited reports, has no cut-off, and means we contact heavy users.

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

Basic and Standard are single-seat plans. Basic includes 5 reports and a larger usage allowance than Free. Standard has unlimited reports under fair use and our largest single-seat allowance, for people who use Amass daily. Business is up to 10 seats in a shared workspace, with one pooled allowance and priority support. Above 10 seats, it's Enterprise.

Can I switch plans later?

Yes. Upgrades apply immediately, downgrades at the next billing cycle. Basic, Standard and Business have no contract.

How does billing work for the Amass API?

The API is billed separately, by usage, every month. Same login, separate billing stream, so a Business subscription and an API account run side by side without double-charging.

Can you build custom agents or integrations for us?

Yes. Amass Professional Services gives you dedicated developer time to build agents, integrations and workflows for your team. Contact us to scope one.

Do you offer academic or non-profit pricing?

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

Start with Free. Move when you’re ready.

No card required, and Free never turns into a paid plan on its own.
