# ChatGPT: ask what decides the answers you want to be in > For the complete documentation index, see [llms.txt](https://attensira.com/llms.txt). > Every page on this site is also served as Markdown: append `.md` to any URL, or send `Accept: text/markdown`. > Connect Attensira to ChatGPT as a developer-mode app over OAuth, then ask which sources decide the answers in your category and where you are missing. - Canonical page: https://attensira.com/integrations/chatgpt - Family: integrations - Last updated: 2026-10-04 - Author: Karl-Gustav Kallasmaa (https://x.com/kallasmaa) - Claims as data: https://attensira.com/claims.json?slug=chatgpt **In short:** In ChatGPT on the web, turn on Developer mode, create an app named Attensira with the URL https://mcp.attensira.com/mcp, choose OAuth and sign in. Turn it on in a chat from the + menu. ChatGPT can then read which sources decide the answers you want to be in, who is named instead of you, and what the crew has waiting. ## What it showed on attensira.com (read 2026-10-04) Asked in ChatGPT: "Which sources decide the answer to "best GEO tools", and are we on any of them?" Call: `deciding_sources prompt="best GEO tools" days=30` Neither engine cites a page of ours for this question. ChatGPT builds it from roundup sites; Perplexity leans on roundups and Product Hunt. | Row | Value | Note | | --- | --- | --- | | bestgeosoftware.com | 14.3% | of ChatGPT's citations, n = 57 answers | | sitepoint.com | 8.6% | of ChatGPT's citations | | geoptie.com | 9.8% | of Perplexity's citations, n = 57 answers | | producthunt.com | 7.3% | of Perplexity's citations | _A question we lose, and the pages that decide it._ ## What can you ask ChatGPT once Attensira is on? - Ask which pages and domains decide an answer you want to be in, ranked by influence, and whether you appear on any of them. - Read mention and citation rates per engine, the prompts you lose and who is named instead, each with its sample size. - See what the crew has waiting for you, and approve or decline it, when your ChatGPT surface allows write tools. - Ask the crew for a win plan on one losing prompt, free, before deciding whether to spend credits on the work. ## How do I connect ChatGPT? 1. **Turn on Developer mode** In ChatGPT on the web, open Settings and turn on Developer mode. On Business and Enterprise, whether you can depends on what an admin allows. 2. **Create the app** Create an app, name it Attensira, enter https://mcp.attensira.com/mcp and choose OAuth. Attensira publishes standard OAuth discovery, so there is no client ID or secret to fill in. 3. **Sign in and allow** Sign in to Attensira and allow. The connection reaches every workspace your organisation owns; with several, name the one you mean in the chat. 4. **Turn it on in a chat** In a chat, open the + menu, choose Developer mode and turn Attensira on. Then ask it to call get_account, which lists your workspaces and the platforms really measured. ## Where does ChatGPT set the limits? - Developer mode and custom MCP apps depend on your ChatGPT plan and, on Business and Enterprise, on what an admin allows. Attensira cannot change that from its side. - Some ChatGPT surfaces restrict which tools an app may call. If write tools such as add_prompts are missing, that is a ChatGPT-side restriction, not a scope problem. - A deciding source is ranked by its share of the citations behind one answer. It is not traffic, and being on it is not a guarantee of being named. ### What did ChatGPT show on our own workspace? In 114 answers to "best GEO tools" over 30 days, neither engine cited a page of ours, and the two engines read different lists. ChatGPT leaned on roundup and ranking sites; Perplexity mixed roundups with Product Hunt. That tells the crew where the work is: not another page on our own site for ChatGPT, but a place on the lists it already reads. ### What is a deciding source, and what is it not? A deciding source is a page or domain ranked by its share of the citations behind one answer, per engine, over a window you choose. It is the closest thing to "what the model read before it answered", and it is still not traffic, authority or a promise. Being on the list gives the crew something to earn; it does not guarantee the next answer names you. Every placement the crew earns is re-read at +7, +14 and +30 days, and a change inside the noise is reported as no change. ## FAQ ### Do I need a client ID or secret? No. Attensira publishes standard OAuth discovery, so choosing OAuth is enough and there is nothing to fill in. ### Write tools like add_prompts are missing. Is my access wrong? Probably not. Some ChatGPT surfaces restrict which tools an app may call. Check what you granted under Connections in Attensira before changing anything; a signed-in connection always carries read and write. ### Why can I not turn on Developer mode? It depends on your ChatGPT plan and, on Business and Enterprise, on what an admin allows. That is decided on the ChatGPT side. ### Can I use an API key instead of signing in? The documented path for ChatGPT is OAuth. Keys are for headless callers that cannot complete a browser sign-in, such as n8n or a CI job. ### Where do I see and revoke what I granted? Under Connections in Attensira. Revoking stops the next refresh; an access token ChatGPT already holds stays valid until it expires. For access you can cut off instantly, use an API key and revoke it. ### Does asking ChatGPT about my numbers cost credits? No. Reading numbers Attensira has already collected is free. Credits are spent by ask and run_automation, which start agent work, and by add_prompts, which adds prompts to track. ## Sources Each entry below is one claim on this page. `retrieved` is the date the exporter or a human last saw the source say this, and nothing more: it is not a publication date and not a promise of re-verification. `cite` is the anchor on the canonical page where this claim is rendered. ### chatgpt-plan-dependent Attensira's connect documentation states that ChatGPT developer mode depends on the plan and, on Business and Enterprise, on what an admin allows, and that some surfaces restrict which tools a connector may call. - source: https://docs.attensira.com/mcp/connect (docs.attensira.com) - retrieved: 2026-10-04 - cite: https://attensira.com/integrations/chatgpt#claim-chatgpt-plan-dependent > If write tools such as `add_prompts` are unavailable, that is a ChatGPT-side restriction, not a scope problem ### chatgpt-oauth-discovery Attensira's connect documentation states that Attensira publishes standard OAuth discovery, so there is no client ID or secret for a ChatGPT app to fill in. - source: https://docs.attensira.com/mcp/connect (docs.attensira.com) - retrieved: 2026-10-04 - cite: https://attensira.com/integrations/chatgpt#claim-chatgpt-oauth-discovery > Attensira publishes standard OAuth discovery, so there is no client ID or secret to fill in. ### revocation-next-refresh Attensira's OAuth reference states that revoking a connection stops the next refresh while an access token already in a client's hands stays valid until it expires. - source: https://docs.attensira.com/mcp/oauth (docs.attensira.com) - retrieved: 2026-10-04 - cite: https://attensira.com/integrations/chatgpt#claim-revocation-next-refresh > Revoking a connection stops the next refresh, but an access token already in a client's hands stays valid until it expires.
