Overview

BRIVOX.AI is built around a simple idea: most AI work doesn't need the most expensive model. About 80% of what people ask an AI to do — drafting, brainstorming, summarizing, translating, basic coding — can be handled beautifully by a well-engineered free model. The other 20% — complex reasoning, elite-level code, deep analysis — is where you genuinely benefit from a frontier model like Claude Sonnet 4.6.

Every other AI platform forces you to choose. Pay $20/month for the premium model whether you need it or not, or stay on the free tier with quality that quietly stops being good enough. BRIVOX.AI breaks that trade-off: get the free model with no limits, ever, and upgrade to Claude Sonnet 4.6 in the exact same conversation when — and only when — you need it.

The headline feature: one chat, two minds. Start with the free model, escalate to Claude mid-conversation, return to free when you don't need the extra horsepower. Same context, same memory, zero copy-paste.

Who BRIVOX.AI is for

  • Developers who need a real coding assistant without a monthly bill, and Claude-grade help when a problem actually requires it.
  • Students and learners who can't afford $20/month subscriptions but still need genuine intelligence, not a stripped-down free tier.
  • Designers, writers, and creators who use AI as a thinking partner across many small tasks every day.
  • Teams and small businesses who want predictable, pay-once costs instead of recurring per-seat licenses.
  • Anyone in Egypt or the Middle East who's been blocked by the lack of local payment methods on global AI platforms.

Quick Start

BRIVOX.AI is designed so you can be productive in under 60 seconds. There's no signup wall in the way of the free experience.

Step 1 — Launch the app

Open chat.brivox.tech directly in your browser. It works on desktop, tablet, and mobile without any installation. On mobile, you can add it to your home screen for a native-feel app.

Step 2 — Start chatting (no signup needed)

The free BRIVOX AI model is available immediately. Ask anything — write code, draft an email, plan a trip, debug a stack trace, translate a document. There are no daily message limits. No "free tier exhausted, upgrade to continue" surprises.

Step 3 — Save your chats (optional account)

Create a free account if you want your conversation history saved across sessions and devices. Account creation takes about 15 seconds and doesn't require a credit card.

Step 4 — Upgrade only when you need Claude

When you hit a problem that needs more horsepower — a complex refactor, a tricky reasoning chain, deep file analysis — buy a token pack. Token packs never expire. The smallest one ($10 for 700K tokens) covers weeks or months of typical Claude usage.

You're never locked in. The free model alone is enough for most users, indefinitely. Token packs are a feature you opt into, not a wall you eventually hit.

The Two Models

BRIVOX.AI ships with two distinct models, and understanding when to use each is the key to getting the most out of the platform.

BRIVOX AI Model (Free)

The flagship free model is a custom blend of multiple frontier models, refined through our own engineering and prompt-tuning. It's not a stripped-down version of someone else's model — it's a system we built and tuned specifically to deliver strong general-purpose intelligence at zero cost to the user.

What it does well:

  • General reasoning, writing, and brainstorming
  • Strong coding across mainstream languages (Python, JavaScript, TypeScript, Go, Rust, PHP, etc.)
  • Multilingual conversation including Arabic, English, French, Spanish, and 40+ other languages
  • Summarization, translation, and content transformation
  • Day-to-day Q&A and learning

Use it for: everyday work where you want quality without thinking about cost.

Claude Sonnet 4.6 (Premium)

Claude Sonnet 4.6 is Anthropic's frontier model, available across all paid token packs. It's the model you reach for when the task is genuinely hard.

What it does best:

  • Elite-level coding — large refactors, complex architectural reasoning, intricate debugging
  • Deep, multi-step reasoning where mistakes compound
  • Image analysis and document understanding
  • Very long contexts where holding many ideas at once matters
  • Tasks that need careful, precise output

Use it for: the work where being right matters more than being fast or free.

Model Switching Mid-Conversation

This is the feature that makes BRIVOX.AI structurally different from every other AI chat platform. In paid plans, you can switch between the free BRIVOX AI model and Claude Sonnet 4.6 inside the same conversation, and the context follows you.

Why it matters

Real work is rarely uniformly difficult. A debugging session might start with "what does this error mean?" (free model is plenty) and end with "refactor this 800-line module into a clean architecture" (now you want Claude). On every other platform, that workflow forces you to copy-paste context between two chats or stay on the expensive model the whole time.

With BRIVOX.AI, you click a button mid-conversation, the next message is processed by Claude with full memory of everything that came before, and you switch back to the free model when the hard part is done. You only burn premium tokens on the messages that actually needed them.

How it works under the hood

  1. Your conversation history is stored independently of which model is active.
  2. When you switch models, the next request includes the full prior context formatted for the new model.
  3. The response is appended to the same conversation thread, indistinguishable from any other message in the chat history.
  4. Switching back is instant — no rebuild, no reload.
Pro tip — let the free model do the warm-up. Use BRIVOX AI to explore, gather context, and draft your first attempt. Then switch to Claude for the precision pass. This pattern saves tokens dramatically while keeping output quality high.

Pricing & Token Packs

BRIVOX.AI uses a token-pack model instead of monthly subscriptions. You buy credits once, they never expire, and you spend them only when you use Claude Sonnet 4.6. The free BRIVOX AI model is unlimited and free regardless of whether you have any tokens.

The plans

Plan Price Tokens File Uploads Best For
Free $0 forever Everyday work, unlimited free model
Pro $10 once 700K Up to 25MB Individuals who want Claude on demand
Business $18 once 1.33M Up to 100MB Teams with a shared workspace
Power $35 once 3M Up to 500MB Heavy users + API access

How tokens are counted

Tokens are units of text, roughly 4 characters of English per token. A token pack of 700K tokens covers:

  • Approximately 500,000 words of conversation (input + output combined)
  • Roughly 1,000-2,000 medium-length Claude conversations
  • About 3-6 months of typical individual usage based on our user data

Tokens are only consumed when you use Claude Sonnet 4.6. Every message you send through the free BRIVOX AI model is free, no matter how long, no matter how many you send.

What happens when tokens run out

When your Claude tokens are depleted, your account continues working normally — you just lose access to Claude until you buy another pack. The free BRIVOX AI model stays available with no interruption. Conversations don't end; you just stop being able to switch to Claude for new messages.

Token packs stack. Buy a Pro pack today, a Power pack next month, and your account has 3.7M tokens total. They all consume from the same balance, in the order they were purchased.

Payment Methods

BRIVOX.AI accepts payments globally and locally in Egypt, so users in regions historically underserved by AI platforms can pay in ways that actually work for them.

International payments (Paddle)

For users outside Egypt, payments are processed by Paddle — a global payment infrastructure trusted by thousands of SaaS companies. Paddle handles VAT/tax calculations automatically and provides full invoicing.

  • Visa, Mastercard, American Express
  • Apple Pay, Google Pay
  • PayPal
  • Bank transfers (in supported countries)
  • Full receipts and tax invoices for business expense reports

Egyptian payments (Kashier)

For users in Egypt, payments go through Kashier — a local payment gateway with full support for the methods Egyptian users actually use day-to-day.

  • Visa, Mastercard, Meeza — credit and debit cards from any Egyptian bank
  • Vodafone Cash — pay directly from your mobile wallet
  • InstaPay — instant bank-to-bank transfer
  • Bank installments — split larger token packs into monthly payments through partner banks
All payments are secured. Card details are tokenized by our payment processors and never touch BRIVOX servers. We're PCI DSS compliant by design — we don't store payment data, our processors do.

API Access (Power Plan)

The Power plan ($35) includes API access, giving you programmatic access to both the BRIVOX AI model and Claude Sonnet 4.6 directly from your own applications, scripts, or workflows.

What you can build

  • Internal tools — Slack bots, CLI assistants, custom dashboards.
  • Automated workflows — content moderation, document classification, ticket routing.
  • Embedded AI features in your own product, paying per-use through your token balance instead of negotiating direct deals with model providers.

Authentication

curl https://api.brivox.tech/v1/chat/completions \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "brivox-ai",
    "messages": [
      {"role": "user", "content": "Hello, what can you do?"}
    ]
  }'

Switching models programmatically

Use brivox-ai for the free model and claude-sonnet-4.6 for the premium model. Only requests against the Claude model consume tokens; BRIVOX AI requests are free for as long as your API key is active.

// Free model — no token cost
await api.chat({ model: "brivox-ai", messages: [...] });

// Claude — consumes from your token balance
await api.chat({ model: "claude-sonnet-4.6", messages: [...] });
Keep your API key safe. Never commit API keys to public repositories. Rotate keys immediately if you suspect exposure. We monitor for unusual patterns and may temporarily suspend keys that show signs of compromise.

Limits & Quotas

Free plan limits

  • Messages: Unlimited
  • Conversation length: Up to standard context window of the free model
  • Saved chats: Unlimited
  • Rate limit: Soft throttle on bursts (≈60 messages/min) to keep the service healthy

Paid plan limits

  • Tokens: As per your purchased pack (Pro 700K, Business 1.33M, Power 3M)
  • File uploads: 25MB (Pro), 100MB (Business), 500MB (Power)
  • Concurrent requests: 3 (Pro/Business), 10 (Power)
  • API rate limit (Power only): 60 requests/min, 1,000/day base — raised on request

Fair use

The free tier is designed for genuine personal and professional use. Automated abuse — scraping, training other models on outputs, mass content generation for spam — is monitored and will result in account suspension. We err on the side of being permissive; if you're using BRIVOX AI to do real work, you're fine.

Privacy & Data

What we store

  • Your conversations (if you have an account and chat history is enabled)
  • Your account email and authentication tokens
  • Token balance and purchase history

What we never do

  • Sell your data to third parties
  • Train models on your conversations without explicit opt-in consent
  • Share conversation content with advertisers or data brokers
  • Store credit card numbers — those are tokenized by our payment processors

Encryption

All traffic between your device and BRIVOX is encrypted with TLS 1.3. Conversation data at rest is encrypted with AES-256. Payment data never reaches our servers in raw form — it's tokenized by Paddle (international) or Kashier (Egypt) before we see it.

Deleting your data

You can delete individual conversations at any time from the chat interface. Account deletion (which removes all stored data permanently within 30 days) is available from account settings. Token balances are non-refundable on account deletion — you can use them out before deleting, or transfer them to another account on request.

Frequently Asked Questions

Is BRIVOX AI really free?

Yes — 100% free, forever. The BRIVOX AI model has no usage limits and requires no credit card. You only pay if you want to use Claude Sonnet 4.6 for advanced tasks, and even then you buy a one-time pack, not a subscription.

What makes BRIVOX AI different from the free model?

The BRIVOX AI model is a custom blend of multiple frontier models, refined through our own engineering and prompt-tuning. It's tuned specifically to deliver strong general-purpose performance without compromising quality the way most free tiers do.

Do token packs expire?

No. Token packs never expire. Buy once, use them whenever — over months, years, whenever you need Claude. There's no clock running against you.

Can I switch between models in the middle of a chat?

Yes, on any paid plan. The conversation context follows the model switch, so Claude picks up exactly where the free model left off — no copy-paste, no restart.

What happens if I run out of tokens?

Your account continues working normally. You lose access to Claude until you buy another pack, but the free BRIVOX AI model stays unlimited and your conversation history is untouched.

Can I get a refund?

Unused token packs are refundable within 14 days of purchase. Once tokens have been consumed, the consumed portion is non-refundable. Full refund policy: ai.brivox.tech/refund.

Is my data used to train models?

No. We never train on your conversations without explicit opt-in consent. Your data is yours.

Do you support payment from Egypt?

Yes — fully. Through Kashier we support Visa, Mastercard, Meeza, Vodafone Cash, InstaPay, and bank installments. This is a first-class payment option, not an afterthought.

Is there an API?

Yes, on the Power plan ($35). The API exposes both the free BRIVOX AI model and Claude Sonnet 4.6 with a standard chat-completions interface compatible with most existing AI tooling.

Can I use BRIVOX AI for commercial work?

Yes. Outputs from BRIVOX AI are yours to use commercially, including in products, content, and client work.

Ready to experience it?

The free model alone outperforms most paid subscriptions. Try it for yourself — no signup, no credit card, no catch.
