Plans, credits and billing
What your plan includes, credits and codes, changing or cancelling a plan, invoices — and why connecting your own AI agent costs nothing here.
When billing is switched off
Billing is switched off: everyone has every feature. The pricing page shows the planned plans without prices, and codes you redeem now are kept on your account for launch.
Your own AI agent is not metered
By default the platform runs no models of its own: you connect Claude Code, Codex, Cursor, Claude Desktop, ChatGPT or another MCP client, your provider bills its reasoning as it does today, and everything the agent does through Hikma — searching the literature, fetching full texts, reading, extracting evidence, writing manuscripts, screening, pooling, analysing data — is free and unmetered. No subscription and no card are needed for it; see Connect an AI agent (MCP) and the API.
How the platform's own AI is counted
This applies only where an administrator has switched the platform's own assistant on (Admin → AI & keys) and billing is live; while billing is off nothing here limits you. Each of the platform's model calls is metered at the provider's cost in US dollars and recorded against the run, the project and you. Your plan includes an allowance per period; credits cover use beyond it; when both are used up the platform's assistant pauses until the period resets, you add credits, or you upgrade. Unattended runs are limited per period on some plans.
Settings → Subscription shows the allowance bar, credits, unattended runs used and the reset date. On a bring-your-own-agent deployment the allowance simply never moves.
Changing plans
- Settings → Subscription → pick a plan → checkout opens in Stripe.
- Manage billing opens the Stripe portal for cards, addresses and receipts.
- Cancel at period end keeps everything until the paid period is over; Resume renewal undoes it.
Invoices appear on the same page with links to the hosted invoice and PDF.
Codes and credits
- Credit codes add credit for the platform's own AI at once.
- Free-days codes unlock a plan for a number of days without a card.
- Discount codes apply at your next checkout — enter the code before choosing the plan.
- Credit packs (one-time top-ups) are sold when billing is on.
