Understanding the free tier

250 calls per month, BYOK required, no API access, and how to check your remaining quota.

Updated 2026-04-13

BYOK is mandatory — even on Free

PromptAssay never provides shared inference credits. On every tier, including Free, you must add your own Anthropic / OpenAI / Google API key before any AI feature works. Each provider gives you a free key in under two minutes — we walk you through it the first time you sign in. Without a key, every LLM call returns a provider key missing error.

What you get

250 LLM calls per 30-day rolling window across all providers in this workspace.
1 seat — the workspace can have exactly one member. Invites beyond seat 1 are blocked at invite time and re-verified at accept time.
BYOK required (non-negotiable) — you must add your own provider key before running anything. See the callout above.
No public API — the REST API is Solo tier and above. You can generate an API key on Free, but every call returns a 403 Forbidden error.
Editor, AI assistant, 7-day version view, import/export — everything else is available. Evaluation suite creation requires Team tier. Full version history requires Solo tier or higher.

Checking remaining quota

Open the Usage or Billing page for the current period's call count and remaining quota. The number is computed on every page load, so it's always within a few seconds of real-time.

Free is per-workspace

A free personal workspace and a free team workspace each get their own 250 call budget. They don't share.

7-day version history view

On the Free tier, the version history panel, search, annotations, and dashboard activity feed only show prompt versions created in the last 7 days. This is a view filter, not a retention policy — every version you've ever created is still stored in the database. When you upgrade to Solo or higher, the 7-day filter drops off on your next page load and the full history reappears instantly. You don't lose anything by staying on Free for a while; you just can't browse or diff older versions until you upgrade.

The filter applies to reads only. You can still create new versions at any rate (every edit, AI suggestion, or restore creates a version), and the latest current_content on every prompt is always visible regardless of age. Restoring or branching from a version older than 7 days is blocked on Free with a clear "hidden on Free plan" error.

Evaluation suites

Free and Solo workspaces cannot create new evaluation suites — the "New Test Suite" button is disabled on the Evaluate page. If you already have suites (from a prior Team subscription or a platform-admin override), you can still view, run, and edit them. New suite creation requires Team tier or higher. See Evaluation suites.
