Notion's ChatGPT token sharing: your AI bill now has two meters
Notion now lets a ChatGPT Plus or Pro subscription pay for some of its AI. It covers one agent and one model family, it still needs a Notion Business or Enterprise plan, and its eligibility changed by tweet within two days of launch. What token sharing is, how to set it up safely, what it covers, and why I still can't tell how much of either allowance a Notion task will use.
On 29 September Notion posted the kind of announcement that gets shared before it gets read:
Yes, you just heard that right.
Got @ChatGPT Plus or Pro? That subscription now covers your AI usage in Notion.
Just connect your plan, pick a GPT model, and go.

A week earlier I wrote that Notion's AI pricing had become a price you cannot compute: the included allowance has no published size, the free credits have no published size, and the annual credits cost more than the monthly ones. So a post saying another subscription now "covers your AI usage in Notion" deserved a careful read. It turns out to be useful for a fairly narrow group of people, and it adds a second allowance to the bill without a published way to convert a Notion task into either one.
What is Notion's ChatGPT token sharing?
A connection between your ChatGPT account and Notion, so that Notion Agent can run GPT models on your ChatGPT plan instead of your workspace's Notion allowance. Notion calls it token sharing. It is Notion's slice of a broader OpenAI program announced at DevDay the same day. From OpenAI's recap:
Use your allowance across 16 partners including Cognition’s Devin, Notion, Vercel, T3,
OpenClaw, and Dactyl, and control how much each can use. Eligible OpenAI usage counts
toward your plan limits.
OpenAI's release notes call it "a limited preview with participating integrations," which is worth knowing before you build habits on it. The other partners are mostly coding tools (Amp, Warp, Kilo Code, Conductor, Devin, open-source clients such as OpenCode); Notion and Vercel are the two that aren't coding agents. OpenAI also widened its existing Sign in with ChatGPT, a plain identity login that some apps support without the plan-sharing part.
On Notion's side, as of 4 October I found one dedicated help page and Notion's posts on X. There is no entry on Notion's releases page, which jumps from Notion 3.7 on 15 September to nothing, and the word "ChatGPT" appears nowhere on Notion's pricing page. That second absence is a little awkward, because OpenAI's own guidelines for partners say a participating app "must clearly show which of its plans support ChatGPT plan usage" on its pricing or plan-comparison page.
Who can use a ChatGPT plan in Notion?
You need a qualifying plan on each side.
On Notion's side, the workspace must be on Business (listed at $20 per member per month, billed annually) or Enterprise (custom pricing), you must be a member rather than a guest, and each person connects their own ChatGPT account. Free and Plus workspaces are out. Readers on X attached a Community Note to Notion's announcement saying exactly that: "This feature requires a Notion Business or Enterprise workspace plan (in addition to ChatGPT Plus/Pro)." Notion's own reply in the thread says it is "starting on our Biz and Ent plans," so that may widen later.
On OpenAI's side, its help page names only two plans:
Anyone can sign in to participating apps and sites with ChatGPT, but the option to use
your ChatGPT plan is only available with Plus and Pro.
ChatGPT Business and Enterprise seats aren't on the list, and OpenAI doesn't say why. A Reddit thread titled "Notion x ChatGPT plan mismatch" made the obvious point: on Notion the feature needs a business tier, on ChatGPT it needs an individual one. In practice it suits people who already have both, Notion Business or Enterprise and their own ChatGPT Plus or Pro, and who have ChatGPT capacity to spare.
The most common requests under the announcement were predictable: the same thing for Claude, support for Notion's Plus plan and education plans, and bring-your-own-key.
How do you connect your ChatGPT plan to Notion?
The connection is short; the part worth doing carefully is the cap. From Notion's help page:
- Go to Settings, then Notion AI, then Usage.
- Under Connected subscriptions, select Connect next to ChatGPT.
- Sign in to ChatGPT and allow Notion to connect to your account.
- Return to Notion.
Or from the agent: open the model picker in Notion Agent and select Connect ChatGPT plan under Subscriptions.
Signing in with ChatGPT and letting an app spend your plan are separate permissions, so make sure you approve plan usage, not only the login. Then, before your first funded request, set a weekly limit for Notion in ChatGPT under Settings, Usage, App limits, Notion, Manage limits. The limit is a percentage of your overall weekly usage. In Notion, the model picker shows which plan a session will use before you send anything; check it the first time.
To stop, you have two places. In Notion, turn off Use your ChatGPT plan, or select Disconnect to remove the account. In ChatGPT, go to Settings, Security and login, Login connections, Sign in with ChatGPT, Notion, Disconnect. Signing out of Notion is not enough, OpenAI notes, and "disconnecting does not reverse usage already recorded."
Which Notion AI features does a ChatGPT plan pay for?
Fewer than "your AI usage in Notion." The help page is precise:
You’ll use your ChatGPT plan only when you select a specific GPT model. The model picker
shows which plan is in use before you send a message.
| Situation | Usage charged to |
|---|---|
| Notion Agent, a specific GPT model selected | Your ChatGPT allowance, while funding is enabled and your app limit allows |
| Notion Agent on Auto, Notion's recommended setting | Your workspace's Notion funding (the help page says "credits" in one place and "plan" in another) |
| Notion Agent with a non-GPT model (Claude, Gemini, Grok) | Your workspace's Notion funding |
| Custom Agents | Your workspace's Notion credits; "This feature doesn't work with Custom Agents" |
| Claude agents in Notion | Your workspace's Notion credits |
| Your ChatGPT allowance runs out mid-session | Notion asks before switching the session to workspace credits |
The help page doesn't say whether Workers, meeting notes, search or other AI features outside Notion Agent are covered, or which GPT models the picker offers under a ChatGPT plan, so I wouldn't assume any of that. The "credits" versus "plan" inconsistency matters too: in Notion's pricing those are different things, credits being a paid add-on and the plan including an allowance, and the page doesn't settle which applies.
There is no Anthropic equivalent. The premium models that moved to credits on 10 September were Claude Fable 5 and 5.1, according to the notice Notion sent my workspace, and for its separate Claude agents Notion says outright that "using your own Anthropic account isn't possible." GPT models were not on that premium list, so as far as Notion's own notices show they were already running on the included allowance. Token sharing moves that usage to OpenAI; it does nothing for the models that cost extra.
How is ChatGPT usage in Notion counted?
Against your ChatGPT Work and Codex allowance, with a cap you set per app. From OpenAI's help page:
When you turn this on, eligible AI requests count toward the ChatGPT Work and Codex usage
included in your plan. You can set a weekly usage limit for each app and review app usage
in ChatGPT settings. How quickly you use your included usage depends on the app and the
tasks you run.
OpenAI does publish rough numbers for that allowance, which is more than Notion does. Its usage guidance estimates, on Plus, about 5 to 45 local messages with GPT-6 Astra or 15 to 160 with GPT-6.1 Sol per five-hour window. What neither company publishes is the conversion: how much of that allowance one Notion Agent request uses. OpenAI says plainly that "usage rates may differ between an app and ChatGPT," and its settings "do not show details about your actions in the app."
The rest of the small print:
- The per-app limit is "a cap, not a separate pool." It stops Notion from eating your week but doesn't reserve anything for it.
- On Plus, the five-hour limit is shared across every app connected this way, so a long Notion session and a long session in another connected tool draw from the same window. Pro has no five-hour limit.
- If your ChatGPT allowance runs out, Notion offers to continue on workspace credits and switches back when your ChatGPT usage resets. Separately, OpenAI lets apps spend purchased ChatGPT credits, an opt-in that is off by default and requires the app's limit to be set to 100%. With automatic purchases enabled, "you may not receive a separate notice when your included usage limit is reached." The sources don't say which overflow wins if you enable both; I would enable neither at first.
- For organizations with audit-log access, an Enterprise feature, Notion records connection and disconnection events. "Usage volume is not available."
Why did Notion's ChatGPT connection fail with different email addresses?
Because at launch it required them to match. The French help page still says so:
Votre compte ChatGPT utilise la même adresse e-mail vérifiée que votre compte Notion.
("Your ChatGPT account uses the same verified email address as your Notion account.") The Korean page says the same. For the people this feature targets, that rule is a dealbreaker: a personal ChatGPT subscription usually sits on a personal address, a Business workspace on a work one. The replies under the announcement said it directly. One user wrote that they "can't use my private subscription with my company email-based Notion account"; another asked Notion to fix "the weird ChatGPT email issue," pointing out that people pay for subscriptions from one address and work from another. A Reddit thread titled "Those of us who use a different ChatGPT email to Notion..." made the same point.
Notion's follow-up on 1 October:
We heard people asking for this yesterday, so we built and shipped it!
You can now set up token sharing even if your ChatGPT and Notion accounts use different
email addresses 🫡
Less than two days from launch to fix, one day from the requests Notion acknowledged, is fast. Two things about it are less tidy. OpenAI's developer guidance tells partners to link accounts by a stable identifier and to confirm a link when emails match, since "an email match alone isn't proof of account ownership"; I found no OpenAI requirement that the two services share an email, so the original rule looks like Notion's own choice. That is my inference; Notion hasn't explained it. And the fix lives in a post on X. The English help page simply dropped the requirement without saying how cross-email connection now works, and the French and Korean pages still carry the old rule. If your connection failed in those two days, nothing on the help page tells you to retry. Retry.
What happens to your Notion data on a ChatGPT plan?
According to Notion, the ChatGPT connection is used "only for billing and usage attribution." Notion says its existing agreements with its AI subprocessors still apply, including the commitment that customer data is not used for training, and that conversations funded by a ChatGPT plan don't appear in your ChatGPT history or memory. Its standard AI policy provides zero retention at the model provider on Enterprise and up to 30 days otherwise, with exceptions it documents on its AI security page; that describes retention at the provider, not storage of your workspace in Notion. On the identity side, OpenAI says a Sign in with ChatGPT app receives your name, email address and profile picture. I can't verify any of this from outside; it is what the two companies state.
Does a ChatGPT plan make Notion AI cheaper?
Only conditionally. Moving work from one prepaid allowance to another doesn't lower either subscription. It helps if you would otherwise run past Notion's allowance and buy credits, and you have ChatGPT capacity you wouldn't use anyway. If both subscriptions already cover your work, connecting them changes who absorbs the usage, not what you pay. And it can cost you: the ChatGPT capacity Notion uses is capacity you don't have for ChatGPT itself or for coding tools on the same five-hour window.
What it doesn't do is make the cost predictable. Before 29 September, GPT usage in Notion Agent drew on Notion's allowance, whose size Notion doesn't publish. Now it can draw on OpenAI's, which OpenAI estimates in ranges but never in Notion tasks. I still can't calculate from anything published how much of either allowance a given Notion workload will consume. The second meter has a scale. It doesn't have the exchange rate.
And the second meter can move. On the same day, The New Stack reported that the Work and Codex allowance of OpenAI's $200 Pro plan falls from 20 times Plus to 10 times on 30 October, with existing subscribers getting 62,500 usage credits that expire on 31 December. OpenAI's own Pro tiers page confirms the shape without the multiples: eligible existing subscribers keep their previous allowance through 29 October and then "move to the lower included usage allowance," while the price "stays at $200/month." If you read my earlier piece, the pattern is familiar: the price holds, the allowance under it changes, the old terms are honoured for a window, and the cushion is credits that expire.
Should you connect ChatGPT to Notion?
If you have both plans and spare ChatGPT capacity, yes, with three precautions. Set Notion's weekly limit before the first request, at a share of your allowance you are willing to lose to it. Leave the credits opt-in off on the ChatGPT side until you have decided, in money, how much you would spend without being asked. And pick GPT models explicitly, because Auto never uses your ChatGPT plan.
If you are a workspace admin, plan as if the feature didn't exist. The connection is per member, the help page offers no switch to stop members connecting, and you won't see their ChatGPT usage. Keep tracking workspace credit spend the way you do now, and treat any drop in it as a bonus you can't forecast.
What does token sharing say about AI pricing in SaaS tools?
That the meter moved again without becoming readable. A month ago the question was how much of Notion's allowance a task takes. Now it is how much of Notion's allowance or OpenAI's, depending on which model you picked, with a weekly cap set in a third place, and with eligibility adjusted by a post on X two days after launch. Anthropic did something similar from the other side when it put a meter on the programmatic side of its subscriptions in May. Each piece is documented somewhere. The sum still isn't a number.
The lesson from the last piece stands, with one addition. A bill you can't compute from published numbers is an estimate. This one is now an estimate kept by two parties, and the only number in the whole arrangement you control is the weekly cap. Set it.
