From Wikipedia, the free encyclopedia
Attention Is All You Need
"Attention Is All You Need" is a 2017 landmark research paper in machine learning authored by eight scientists working at Google. The paper introduced a new deep learning architecture known as the Transformer, based on the attention mechanism proposed by Bahdanau et al. in 2014.
It is considered a foundational paper in modern artificial intelligence, and a main contributor to the AI boom, as the transformer approach has become the main architecture of a wide variety of AI, including large language models.
Background
Before the Transformer, dominant sequence transduction models were based on recurrent or convolutional neural networks…

- Introduces the Transformer, replacing recurrence with self-attention end-to-end.
- Multi-head attention learns parallel relationships across the full sequence.
- Sinusoidal positional encodings let the model reason about word order without recurrence.
- Trained on WMT 2014 EN→DE and EN→FR, sets a new state of the art on both.
- Becomes the foundation for BERT, GPT, and almost every modern LLM that follows.

Features
A browser AI assistant that can actually help.
BrowsePal is free to use and built for private, everyday browsing work. Chat with live page context, give the assistant useful actions, and choose exactly which model provider or MCP server receives each request.
Agentic browsing on demand
Ask BrowsePal to research, compare, click, type, navigate, and capture screenshots in the active tab while you stay in control.
MCP server support
Connect MCP servers to bring your own tools, data, and workflows into each chat. Turn them on only for the conversations that need them.
Pages, tabs, files, images
Attach the current tab, selected text, screenshots, open tabs, PDFs, files, and images so answers match the context you are working with.
YouTube summaries
Attach a YouTube video and ask for a quick summary, timestamped notes, action items, or a comparison with another video.
Private by default
Use BrowsePal with no account. Sign in only if you want passphrase-protected encrypted sync for chats and settings across devices.
Attach anything
Bring the right context into every answer.
Use Attach to pull the exact context you need into a chat before you ask: the page you are on, a selection, another open tab, a screenshot, a PDF or file, or a YouTube transcript. BrowsePal keeps answers grounded in what you are actually looking at.
Attach six sources
- pageCurrent pageReadable content of the tab you are on
- selectionSelectionJust the text you highlighted
- tabAnother tabPick from tabs you already have open
- captureScreenshotViewport, full page, or a region you draw
- fileFilePDF, text, markdown, JSON, CSV, or image
- videoYouTubeTranscript and metadata from a watch URL
Agentic browser use
Let the assistant take the next step.
Turn on browser use and BrowsePal can click, type, scroll, and navigate the active tab for you. Ask it to research a product, book a table, fill a form, or pull data off a site, then keep chatting with what it finds.
- You stay in control of when browser use is enabled.
- Turn any website into a workspace for research, shopping, forms, and everyday tasks.
- Get instant summaries, extracted details, and clear answers from the page in front of you.

Your tools. Your instructions. Your skills.
BrowsePal is the side panel you shape. Connect MCP servers, write your own system instructions, and add reusable skills that the assistant pulls in only when a chat needs them.
- MCP servers
Plug in Model Context Protocol servers for your own tools, docs, and workflows. Enable them only in the chats that need them.
- Custom instructions
Give the assistant a lasting persona, tone, and house rules. Kept separate from your chats, applied to every turn.
- Skills
Add ready-made prompts as SKILL.md files. BrowsePal activates them on demand so guidance stays out of the way until you need it.
Privacy
Private by default. Useful by design.
BrowsePal is built for bring-your-own-key AI. Your API keys stay encrypted on your device, chat history stays local unless you choose sync, and you decide which provider or MCP server receives each request.

What happens to your API key
- 1 Add your provider keyConnect directly to Anthropic, OpenAI, Gemini, Grok, OpenRouter, or any OpenAI-compatible endpoint.
- 2 Wrap it locallyBrowsePal derives an AES-GCM-256 key with PBKDF2-SHA256, 150,000 iterations, and a per-install 32-byte salt.
- 3 Store only ciphertextChrome storage receives a v1 payload with a random 12-byte IV plus ciphertext. Synced settings never include API keys.
- 4 Decrypt only for requestsThe extension decrypts locally and sends the bearer token directly to your selected provider, not BrowsePal.
-
API keys stay on your device
Your provider keys are encrypted locally and are never sent to BrowsePal servers. Even if you sign in, API keys are excluded from sync.
-
No BrowsePal proxy for your chats
Prompts, attachments, and browser context go from your browser to the model provider or MCP server you choose. We do not inspect or store them.
-
Sync is optional and encrypted
Sign in only when you want chats and settings on another device. Your passphrase encrypts them before they leave your browser, so our servers store unreadable data.
Optional encrypted sync
Your chats can follow you without becoming ours.
BrowsePal works fully local with no account. If you want cross-device continuity, sign in and set a passphrase. Your chats and settings are encrypted before sync, and only your passphrase can unlock them.
API keys are never synced. They stay encrypted on each device where you add them.

Set up encryption
Choose a passphrase to encrypt your synced settings and chat history end-to-end. The passphrase never leaves your device. The server only stores opaque ciphertext and cannot read any of your content.

FAQ
Answers before you install.
Is BrowsePal free?
Yes. BrowsePal itself is free to use. You bring your own model access through a direct provider account, an OpenRouter key, or a local OpenAI-compatible server. If your model runs locally, BrowsePal can be used without provider usage costs.
Is my data private?
BrowsePal is private by default. API keys are encrypted locally, never sent to BrowsePal servers, and never included in sync. Chat history stays on your device unless you turn on encrypted sync. There is no analytics, telemetry, ads, or third-party tracking in the extension.
Which AI providers and models are supported?
Connect directly to Anthropic (Claude), OpenAI (GPT), Google Gemini, xAI Grok, and OpenRouter, or use any OpenAI-compatible server such as Ollama, LM Studio, vLLM, Together, Groq, or your own endpoint. Through OpenRouter you also get one-key access to hundreds of models including Claude, GPT, Gemini, Llama, DeepSeek, Qwen, and Mistral. BrowsePal fetches each provider model list automatically, so new releases show up without a client update.
Can I use local models?
Yes. Point BrowsePal at any local OpenAI-compatible endpoint such as Ollama, LM Studio, or vLLM. Prompts never leave your machine, and there are no usage fees for local inference.
Can it chat with tabs, files, and images?
Yes. BrowsePal can use the current tab, selected text, screenshots, open tabs, PDFs, text files, tables, JSON, and images as chat context. You can also attach a YouTube video transcript for summaries, notes, timestamps, and follow-up questions.
What does agentic browser use mean?
When you enable browser use, BrowsePal can help with actions in the active tab, such as clicking, typing, navigating, scrolling, waiting for page updates, switching tabs, and capturing screenshots. It is designed for user-directed workflows like research, comparison, and form-heavy tasks.
Does BrowsePal support MCP servers?
Yes. You can connect MCP servers and decide which ones are available in each chat. That lets BrowsePal work with your own tools, private knowledge sources, and custom workflows without turning them on globally.
How does encrypted sync work?
Sync is optional and zero-knowledge. Your passphrase derives a key via PBKDF2-SHA256 with 600,000 iterations and a random 32-byte salt, which wraps a per-user AES-GCM 256-bit data key. Chats and settings are encrypted with that data key before leaving your browser. The server only sees ciphertext plus the wrapped key, so it cannot read your conversations or derive the passphrase. A new device restores data only after you unlock with the same passphrase. API keys are never included in sync.
Does it work on Firefox?
A Firefox build is available. Firefox does not fully match Chromium's side panel API, so some interactions feel different, but the core BrowsePal experience runs.
