What it does

Everything you keep re-doing — automated.

AI Identity
Build your identity once — name, role, goals, communication style, you name it. Endless customization. Throttle injects it silently and automatically across ChatGPT, Claude, and Gemini. No re-explaining. Ever.
Response Presets
Switch between Concise, Developer, Detailed, and Balanced in one click. Fully customizable — your preference is injected automatically every chat. No pasting. No repeating.
Context Meter
AI gets worse in long conversations. Throttle shows a live bar so you know exactly when quality drops — and automatically compresses your conversation so nothing gets lost.
Compact & Continue
When your context is almost full, one button asks the AI to summarize your entire conversation. Resets the meter so you can keep going without starting completely from scratch.
Instant Switching
Change your preset or identity profile mid-session from the floating toolbar — no need to open settings. Changes take effect on your very next message.
Private by Design
Your settings live in your browser's local storage. We never read your conversations, never sync to servers, and never require an account. Your data is yours.

Set it once. It runs itself.

1
Install the extension
Add Throttle from the Chrome Web Store. No account, no signup — it's live the moment it installs. The toolbar appears automatically on ChatGPT, Claude, and Gemini.
2
Build your identity
Open the popup and fill in your AI Identity — name, role, goals, style, whatever you want AI to know about you. Endless customization. Takes 60 seconds. You'll never do it again.
3
Chat normally — Throttle handles the rest
Every new conversation starts with your context already loaded. The AI knows who you are and how you want it to respond — from message one, every time.

One click to change how AI responds.

No more pasting "please be concise" into every chat. Pick your mode and Throttle injects the right instruction automatically — before every message you send.

Switch instantly from the floating toolbar, mid-conversation. Changes take effect on your next message.

⚖️
Balanced
Clear and direct. Smart default for most conversations.
✂️
Concise
Short answers only. No fluff, no filler, no essays.
💻
Developer
Code first. Terse and technical. Skip the prose.
📚
Detailed
Full depth. Complete answers, every detail included.

Know when your AI is running out of memory.

Every AI has a context window — a limit to how much conversation it can hold. Once you hit it, responses get vaguer and the AI starts "forgetting" what you said earlier.

Throttle's live bar shows you exactly where you are. When it turns red, hit ⚡ Compact & Continue — Throttle asks the AI to summarize your conversation so nothing gets lost.

Common questions.

Does Throttle read my conversations?

No. Throttle never reads, stores, or transmits your conversations. It only prepends a small instruction block to the first message of each new conversation — everything stays between you and the AI. We have no server-side component that touches your chats.

Does it work with free ChatGPT, Claude, and Gemini accounts?

Yes. Throttle works on all plans — free and paid — for all three platforms. It injects instructions at the browser level, so no special API access or paid subscription to the AI is required.

Will the AI see the Throttle instructions?

Yes — the instructions are prepended to your first message in a compact format. The AI processes them naturally. You don't need to change how you write prompts; just type normally and Throttle handles the formatting.

What happens when ChatGPT or Claude updates their interface?

We monitor all three platforms and ship updates quickly when they change their UI. Chrome will update the extension automatically. If the toolbar ever stops appearing, check for a pending extension update in Chrome.

Is my data stored anywhere?

Your settings (presets, identity profile, preferences) are stored locally in Chrome's built-in storage on your device. Nothing is synced to our servers. If you uninstall the extension, all data is deleted by Chrome automatically.

How accurate is the context meter?

It's an estimate based on message count and typical token usage per exchange. It won't match the exact token count from each platform's internal systems, but it gives you a reliable directional signal — you'll know when you're getting close to the limit before it starts affecting response quality.
