LiteAI Chat: a web UI for Claude in your browser and on your phone

The sk-bf-… key you buy at liteai.tech/pricing is more than an API key. After payment, LiteAI automatically provisions a browser chat at chat.liteai.tech and sends the credentials to the email you entered at checkout. The chat exposes the same Anthropic models (Opus4.8, Sonnet4.6, Haiku4.5, fable-5) you already paid for in tokens, plus conversation history, search, file uploads and quick mobile access.

The chat is built on Open WebUI — the open-source AI platform (144K GitHub stars, 447K-member community) that LiteAI hosts for you. No installs, no Docker, no sign-up on third-party services — just the login and password that arrived by email after your first purchase.

What's included in the chat

• All four Anthropic models you paid for:
  • Claude Opus4.8 — the flagship for deep reasoning and long context.
  • Claude Sonnet4.6 — the daily driver for most tasks.
  • Claude Haiku4.5 — for speed and cheap workloads.
  • Claude fable-5 — for reasoning and multi-step instructions (separate plan).
• Conversation history — every session is stored on the LiteAI server and reachable from any device.
• Mobile web access — chat.liteai.tech works in Safari/Chrome on iOS and Android with a responsive layout.
• File uploads — PDF, images, text documents (for models with multimodal support).
• Prompt library — system prompts for common jobs (code, translation, analysis).
• Voice input — browser-native speech-to-text.
• Search & web browser — keyword search across every conversation.

Technically this is a full Open WebUI (the same stack that Anthropic, Google and many enterprise companies deploy on their own hardware) — LiteAI handles install and maintenance for you.

How to log in — 4 steps

Step 1. Buy a LiteAI key

If you already have an sk-bf-… key in the Telegram bot @liteaitech_bot, skip this step.

If not:

1. Open liteai.tech/pricing.
2. Pick a package by volume (1M for ₽30 to test, 5M for ₽150 for active work, 100M for ₽2,000 for production).
3. Enter your email at checkout — the chat login will be sent there.
4. Pay via SBP, card or USDT.
5. Within 30 seconds the sk-bf-… key is in both the Telegram bot and your inbox.

Step 2. Open the email

The message contains:

• Login — your email address.
• Password — auto-generated, format XXXX-XXXX-XXXX.
• Link to https://chat.liteai.tech.

You can change the password under Settings → Account.

Step 3. Log in and pick a model

https://chat.liteai.tech

After login:

1. At the top of the chat — Model selector (Opus4.8 / Sonnet4.6 / Haiku4.5 / fable-5).
2. Left panel — History with search across all conversations.
3. At the bottom — the input field with a + button for file uploads.

The default is Sonnet4.6 — optimal for most tasks. For harder work switch to Opus4.8 or fable-5.

Step 4. First conversation

Try something like:

Explain how to add the Anthropic API to my Express.js server, with env-based auth and an OpenAI fallback

Within a few seconds you'll get the answer. All tokens (input and output) are billed from the same LiteAI balance as the API. If the balance hits 0 the chat returns "Insufficient balance" — top up at liteai.tech/pricing.

Usability: what sets LiteAI Chat apart from claude.ai

Feature	claude.ai (Pro)	LiteAI Chat (web)
Browser chat	✅	✅
Mobile access	✅ (via PWA)	✅ (responsive web)
Available in Russia	❌ (needs VPN + Pro subscription)	✅ (just email + password)
Pay in rubles	❌ (Pro only, $20/mo)	✅ (SBP / card / USDT)
Same tokens for API + web	❌ (Pro and API billed separately, $20 + pay-as-you-go)	✅ (one sk-bf-… key for both)
Open WebUI features (multi-modal, file upload)	⚠️ partial	✅
Save/Export chat history	built into claude.ai	✅ (JSON, Markdown)
Can self-host on another server	❌	❌ (LiteAI Chat is SaaS, not self-hostable)

The main advantage: LiteAI Chat uses the same sk-bf-… key you already use in Claude Code or OpenRouter. One balance powers three places at once: the API, LiteAI Chat, LiteAI for OpenClaw/LiteRouter, etc.

What you get in LiteAI Chat out of the box

Voice input and output (TTS/STT)

The Open WebUI interface uses the browser-native Web Speech API for speech recognition — no separate app required. Just tap the microphone icon in the input field.

File uploads and multimodal

For models with vision support (Opus4.8 and Sonnet4.6) you can attach:

• Images (PNG, JPEG, WebP) — the model will describe the content or answer questions about the image.
• PDF — the model reads the document and answers questions on it.
• Text files (.txt, .md, .csv, .json) — handled as long context.

The file size limit is ~50 MB (subject to the model's context window).

Prompt library

Presets for common tasks:

• Code Review — PR feedback focused on security/performance/correctness.
• Explain Like I'm Five — simplify a complex topic.
• Translator RU↔EN — translation that preserves technical terms.
• SQL Optimizer — analyze and optimize SQL queries.

To create your own preset: Settings → Prompts → + New Prompt.

History search

Every conversation is stored in an encrypted SQLite on the LiteAI side. Search is fast even with 10K conversations. You can delete any conversation via its context menu.

How it works under the hood

When you send a message in LiteAI Chat:

1. The web UI at chat.liteai.tech authenticates with a JWT token (email + password).
2. The request goes through the LiteAI API → LiteAI proxy → Anthropic API (/v1/messages or /v1/chat/completions).
3. The response streams back to Open WebUI via SSE.
4. All tokens are debited from the same balance your sk-bf-… key uses in Claude Code, Cursor, opencode, etc.

The LiteAI Chat advantage: the same Open WebUI that Anthropic uses internally (open-source), but fronted by the LiteAI proxy that already works in Russia without a VPN. You don't provision Docker, configure HTTPS or worry about server hosting — LiteAI has done it.

What to do if something doesn't work in LiteAI Chat

The login email never arrived

• Check the Spam folder in your mail client.
• In the Telegram bot @liteaitech_bot run the "Chat login" command — the bot will resend the password.
• If you mistyped the email at checkout — write to support@liteai.tech with your purchase receipt and we'll update it.

Forgot the chat password

• LiteAI Chat has a "Forgot password" link on the login page. Click it → email → get a new password.
• Or via the Telegram bot @liteaitech_bot: run "Reset password" → a new password arrives in the bot.

The "Open chat" button in the dashboard doesn't work

• That means your email isn't linked to a chat account. Write to support@liteai.tech with the email and your Telegram username — we'll link it within 15 minutes.

The chat says "Insufficient balance"

• This is expected behavior at zero balance.
• Top up at liteai.tech/pricing — the key and chat access stay the same, the balance just increases.

Summary

LiteAI Chat is a web UI for Claude that activates automatically when you buy tokens. No extra sign-ups, no extra payments. The same sk-bf-… key, the same balance, the same Anthropic model lineup — just with a browser-friendly email/password entry instead of an HTTP API.

It fits: quick notes in the browser, mobile access to Claude (when a terminal isn't handy), explaining code to a colleague (via a share link), prototyping before going to production through the API.

If you already bought a key in LiteAI — open https://chat.liteai.tech and log in with the email/password from the message. If not — start with the 1M for ₽30 package at liteai.tech/pricing to get both an API key and chat access in a single payment.
