Ask in plain words. ChatGPT calls PackIndex and answers with the benchmark, its date and what to do next: check a quote, cost a pack or find suppliers.
Available in the ChatGPT app directory. Uses your PackIndex plan; nothing is billed through ChatGPT.
Illustration of PackIndex in ChatGPT; the real screens may differ slightly. The PP value is real PackIndex data (free view as of 2026-08-03 · live on Essential).
“What does PET resin cost today?” Value in USD and your currency, with 1-week, 1-month and 1-year change.
Open →“My supplier quotes $1,450/t for PP. Is that fair?” Verdict against the benchmark and its 12-month range.
Open →“Our contract was €1,300/t in March, 60% linked to PP. What should we pay now?”
Open →“Compare kraftliner in Europe and the US” and 12-week outlooks with a confidence grade.
Open →“Design a mailer box for 2 mugs and cost it.” Spec and priced bill of materials — 1 Suite run.
Open →“Who can make my folding carton in Canada?” Live Exchange listings and matched converters.
Open →Only after you confirm. Up to 3 suppliers per request, within your Exchange plan.
Open →Open the PackIndex app in ChatGPT (button above) or go to Apps and search “PackIndex”, then select Connect. Mention PackIndex in a chat, or pick it from the + menu, to use it.
Not for price questions. When a question needs your own data — projects, RFQs, PACKIQ agents — ChatGPT opens the PackIndex sign-in and you choose the permissions.
No. Price questions work without an account and show the free reference values. Signed in, your own PackIndex plan applies exactly as on the website: live values on Essential and above, Suite runs for Design Studio, PACKIQ credits for agents and your Exchange plan for RFQs.
Only what the assistant passes to a PackIndex tool, such as an index code or a quantity — never your chat history, memories or files.
Remove PackIndex in the assistant, or open opnplatform.com/portal → Settings → MCP Access and revoke it.
PackIndex also works in Claude · Microsoft Copilot · Cursor · Grok · Meta Muse, and any MCP client — tools, permissions and setup.
