Two questions I get asked more than almost anything else. First: "What even is a token?" Second: "How do I stop Otter AI from randomly joining my calls?" Both have answers way more useful than what most articles give you.
What Is a Token in AI?
The real explanation — not the abstract one.
A token is the smallest unit of text that an AI model reads and processes. When you type a message into ChatGPT, Claude, or Gemini — the model doesn't read it the way you do. It converts your text into a list of numbers, processes those numbers, predicts what numbers should come next, and converts the result back into text.
But it's not always that clean. The word "unbelievable" might become two tokens: "unbeliev" and "able". A space before a word is often its own token. Even punctuation marks are tokens. Think of tokens as building blocks optimized for computational efficiency, not readability.
Word: "tokenization" → never seen in training?
Subwords: "token" + "ization" → model knows both pieces
Result: model processes 2 tokens instead of failing on 1 unknown word
The Three Types of Tokenization
- Word-based — splits at spaces and punctuation. Simple, but struggles with new words and technical terms.
- Character-based — breaks into individual characters. Handles anything, but creates very long sequences.
- Subword tokenization — the method most modern AI uses. Breaks words into meaningful chunks that balance vocabulary size and flexibility. GPT models use about 50,000 tokens in their vocabulary.
Why Tokens Matter For You
Where abstraction meets your actual experience.
Tokens stop being abstract the moment they affect your workflow and your wallet. Here's where they actually matter:
Context Windows
Every model has a maximum token count it can consider in one conversation. Exceed it, and the model starts forgetting earlier parts of your chat.

API Cost
You pay per token. Input tokens (what you send) are cheaper than output tokens (what the model generates). Output tokens are consistently 4–8x more expensive across all models.

Pro Tips to Save Tokens
Remove filler from prompts — every unnecessary word costs money. Use smaller models for simple tasks. Leverage cached inputs (75–90% cheaper). Use Batch API for 50% off non-real-time workloads.
The Hidden Environmental Cost
Creating one image uses roughly the same compute as charging your phone. Token cost and environmental cost move together — which connects directly to the water and energy discussions around AI infrastructure.
How to Manage and Turn Off Otter AI
When a helpful tool becomes an uninvited guest.
Otter AI is an AI-powered transcription and note-taking service that connects to Zoom, Google Meet, and Microsoft Teams. The feature that causes most confusion is OtterPilot — when enabled, it automatically joins all your scheduled meetings without asking permission each time. Even if you've canceled your subscription, Otter can keep showing up until you manually turn off auto-join or disconnect it from your calendar.
How to Stop Auto-Join
- Sign in to your Otter account
- Go to Account Settings → Meetings
- Find OtterPilot settings
- Toggle off "Auto-join all meetings"
- Check Calendar view for individual events still toggled on
- Open iPhone Settings
- Tap Apple ID → Subscriptions
- Find Otter AI in the list
- Tap Cancel Subscription
- Confirm when prompted
- Open Google Play Store
- Tap Payments & Subscriptions
- Find Otter AI
- Tap Cancel Subscription
- Confirm to avoid next billing cycle
Remove Otter from a Live Meeting
If Otter has already joined a meeting you're currently in:
- From Otter homepage: Navigate to the calendar section → click the stop recording button on the live conversation.
- From Otter app: Go to My Conversations → select the recording → click Stop Recording.
- From meeting host controls: If you have host permissions on Zoom, Google Meet, or Teams, remove Otter like any other participant.
Disconnect from Calendar (Nuclear Option)
To completely sever the connection:
- Google Calendar: myaccount.google.com/security → Third-party apps → find Otter.ai → Remove Access.
- Microsoft/Outlook: account.microsoft.com/privacy → Apps and services → find Otter.ai → Remove.
Critical Timing
Cancel at least 24 hours before your next billing date to avoid being charged for another cycle. You keep paid features until the end of your current billing period. Otter also offers a Pause Plan option if you don't want to cancel permanently.
Delete Your Account Entirely
Canceling stops billing. Deleting removes all data permanently. If you've recorded anything sensitive (HIPAA or FERPA content), delete those recordings before closing your account. Go to Account Settings and locate the account deletion option — Otter's help center has direct guidance if you can't find it.
Did the Token Explanation Click?
Tokens are the invisible backbone of every AI interaction — they determine what the model can remember, how much it costs, and how efficiently it processes your input. Otter AI is genuinely useful until it starts joining meetings uninvited. The fixes are straightforward once you know where to look.
