ChatGPT Go is $8 a month | AIToolsEssentials

ATEAIToolsEssentialsDisclosure

Eight dollars is easy to add without thinking. That’s why it matters this week. A cheap seat next to a chat seat you already renew is still another renewal date.

Claude

If the weekly job is drafts, long docs, and careful edits, keep one chat seat you actually open. Claude still has the cleanest sticker we have for that. Official page checked 18 Sep 2026: Free is $0. Pro is $17 a month with a $200 annual prepay, or $20 month to month. Max starts at $100. Team seats list Standard at $20 and Premium at $100. Pro is the keep for chat, research, and rewriting. Max is for the days that eat the limit.

Do not stack Claude Pro next to ChatGPT Go “just to try the $8.” Run the same real brief in Free ChatGPT and in the Claude seat you already renew. If Go only duplicates answers you already get, leave it. If you live in GPT for multimodal work and Claude for long writing, pick the one job each seat owns and cut the third window.

One cut to watch: Plus at $20 plus Claude Pro at $17 is $37 before Go ever enters the picture. Add Go and you’re paying three chat bills for overlapping drafts. Keep the seat that finishes your weekly work. Put the other on Free until a real task fails without it.

This week

Pricing Watch’s baseline is 8 Oct 2026. The ChatGPT dollar print on 1 Oct is the move that opens this letter. A few other seats people stack still matter if a renewal is coming. Full tracker: Pricing Watch.

ChatGPT (1 Oct 2026): Go $8, Plus $20, Pro $100 — Astra listed as a Pro feature, not a new SKU.

Claude (18 Sep 2026): Pro $17 prepaid or $20 month to month; Max from $100.

Cursor (18 Sep 2026): Pro $20, Pro Plus $60, Ultra $200, Teams $40 a user — editor seat, not chat.

Grok (1 Oct 2026): Free $0, SuperGrok $30, SuperGrok Plus $100. API flagship on that check is grok-4.7 at $2 input / $6 output per 1M tokens.

Gemini Notebook

NotebookLM is now Gemini Notebook. Google’s FAQ says the rename took effect in July 2026; our re-check on 1 Oct 2026 found a dedicated plans page. The product stays free for individuals with standard limits and up to 50 sources per notebook. Higher limits come through Google AI Plus, Pro, and Ultra via Google One. That plans page still does not print US-dollar amounts.

For the chat/Google side of the same wallet, Gemini personal pricing checked 18 Sep 2026 lists Free at $0, Google AI Pro at $19.99 a month, and Ultra from $99.99. If you already pay Google AI Pro for Docs and Gmail help, Gemini Notebook’s higher limits may already sit in that bill. If you only need grounded Q&A on uploaded files, stay on the free notebook until a real source set hits the 50-source wall.

One thing

Before you add ChatGPT Go — or any other cheap seat next to a chat you already renew — write down the assistants on your card. Run one real brief in Free ChatGPT and in your keep seat. If the $8 tier does not finish a job the Free tier bungles, leave it. Then run the free Stack Audit. It stays in the browser, no login, and it maps overlap by job.
