Chap by ChatPanel — Privacy-First AI Agent

Meet Chap, your AI agent for work: Claude Code, Codex or any model in a privacy-first side panel for meetings, chats & notes.

ChatPanel is a privacy-first AI assistant in your browser's side panel. Chat with the coding agents already on your computer, such as Claude Code and Codex, with your own local or API models, or with a private model that runs right in your browser. It uses the context of whatever tab you're on, without routing your data through anyone's servers. Most browser AI extensions send your prompts (and your page) to their cloud. ChatPanel doesn't, unless you choose to. It runs a model on your own machine, talks to the coding agents already running on it, or uses a model endpoint you control, and it can strip personal data out of anything that does go to a cloud model. CHAT INSTANTLY, ZERO SETUP — the moment you install ChatPanel you can chat: a small private model runs right in your browser on WebGPU, with no API key, no account and nothing to install. Your first message downloads it once (~700 MB, cached); after that it works offline and 100% on-device. Pick a bigger model from the built-in catalog, or bring your own, whenever you want more power. YOUR LOCAL AGENTS — the optional ChatPanel Gateway (listening on 127.0.0.1 only) lets ChatPanel talk to the AI coding agents installed on your computer, using your own logins and your own compute. The popular ones are detected automatically, and you can add any other command-line agent yourself. Nothing is routed through our servers. BRING YOUR OWN MODEL — connect any cloud AI provider with your own API key, a model running on your own machine, or any OpenAI- or Anthropic-compatible endpoint you host. One-click presets cover the major providers and local runtimes, and some providers support one-click sign-in, so there is no key to paste. NOTES — a notebook your AI writes with you. Capture a chat reply, a page or a meeting takeaway into notes that link to each other with [[wiki-links]], so your workspace becomes a connected, searchable graph. Co-write inside a note (with authorship tracked), research across your own notes, chats and meetings and the web, and turn a selection into a plan. Everything is stored locally and encrypted at rest. BUILT-IN PII REDACTION — ChatPanel can detect and mask personal data (names, emails, phone numbers, organizations, locations) in your messages before they reach a cloud model, then restore the real values in the reply. Detection runs locally, on your device. An optional local Privacy Gateway extends the same redaction to command-line tools and your own apps. LIVE MEETINGS — in the major video-call apps, ChatPanel turns a call's live captions into running notes, decisions and action items, plus a searchable transcript you can ask about afterwards. It reads the captions only — never your audio or video — and everything stays on your device. An optional local Gateway adds on-device dictation, with your audio never leaving your machine. ACT ON PAGE (optional, opt-in) — let your chosen agent fill in forms and click elements on the current tab for you. It runs only on the tab you're acting on, only while you ask it to, and entirely on your machine. TOOLS — connect Model Context Protocol (MCP) servers, from a built-in catalog or your own, so your agent can use real tools. ChatPanel picks the most relevant tools for each message, and can keep personal data redacted when a tool is remote. WHAT YOU CAN DO: • Chat from any tab without leaving the page — instantly, with a private in-browser model or the agent/model of your choice • Pull in the current page, your selected text, several open tabs, or a pasted URL as context • Attach an image or a screenshot of the page for vision-capable models • Summarize pages, analyze a URL, explain the code in a repo, and more • Keep linked, searchable Notes your AI co-writes with you — with research across your workspace and the web, and one-tap plans • Live AI meeting notes & transcripts from your video calls — captured locally, with optional on-device dictation • Keep a searchable, local history of every conversation, organized by topic • Define your own agents, per-agent system prompts, and reusable skills / prompts • Back up and restore everything — with optional passphrase encryption, and automatic local backups on Pro PRIVACY-FIRST BY DESIGN: • A private model can run entirely in your browser — no key, no account, no cloud • Your settings, chat history, notes, and API keys stay in your browser • Page content is read only when you explicitly attach it, and is sent only to the agent or model you chose • Optional on-device PII redaction before anything reaches a cloud model • Optional passphrase encryption for your local backups • All extension logic ships inside the package — the optional in-browser model downloads its weights once, on your request, then runs fully on-device • No telemetry on your conversations; the only server call is a license check that carries no chat content • Verifiable, not just promised: the extension's every request is visible in DevTools, the gateway prints an egress audit (chatpanel-gateway --audit), and the redaction engine is source-available on GitHub. PRICING: • Free — the in-browser model, one local agent + one model endpoint of your choice, current-tab & URL context, local history, your first 10 notes, live meeting notes, built-in skills • Pro — all your agents & endpoints, multi-tab / whole-window context, unlimited notes with the AI co-writer, custom skills, per-agent system prompts, PII redaction with names/orgs/locations, exports, and encrypted auto-backup • Team — cloud sync, shared agents & skills, hosted agents, SSO QUICK START — the in-browser model works with zero setup.

Local by design. Your agents, your models, your data.
