What is this?

Apogee is a browser extension (Firefox and Chrome) for AI summarization that runs entirely locally — no cloud, no API keys, no accounts, no telemetry. It was built by GitHub user darshi1337 as a privacy-preserving rebuild of Mozilla's discontinued Orbit project, which had routed summarization through centralized servers. Apogee supports multiple local inference backends: WebGPU-accelerated llama.cpp in the browser, WebAssembly builds, and connections to local Ollama or llama-server instances on 127.0.0.1. It summarizes web pages, PDFs, YouTube transcripts, and emails. The extension is open source on GitHub.

Why it matters to Scott

Apogee is a shipping browser extension that concretely implements Scott's advocated architecture: local-first inference in the browser (WebGPU/WASM/llama.cpp), multiple sovereign backends (Ollama, llama.cpp), zero cloud dependency, and privacy-preserving design — directly realizing patterns from Runtime Containment, SiloOS, Sovereign Software Assurance, and Hardware-aware local inference. It also serves as a live case study for the Mozilla Orbit discontinuation analysis in Cheap Thinking Makes Strategy Harder and AI-Mediated Disruption: a third party rebuilt the cloud-dependent product locally, proving the local-first alternative is viable now.

It helps the project reach more contributors. ## Get Started 1. Install Apogee from the [Chrome Web Store](https://chromewebstore.google.com/detail/apogee/pgemlpomhkdcjjjcpnjlebalnfglomog). Or use [Firefox Add-ons](https://addons.mozilla.org/en-US/firefox/addon/apogeeext/). 2. Open a page, video, PDF, or DOCX file, or paste text into the Apogee popup. 3. Pick a summary format and select Summarize. The first in-browser run downloads the picked model. Cached models run offline after that. For larger models, set up [Ollama](https://github.com/darshi1337/apogee/blob/main/OLLAMA.md) or [llama.cpp](https://github.com/darshi1337/apogee/blob/main/LLAMACPP.md) in Settings. ## Why Apogee The discontinued Orbit project from Mozilla inspired Apogee. Orbit tried browser-based page summarization, but it used central API servers and stored summaries on servers. Apogee fixes the design and privacy problems of Orbit by staying local-first: - Local by default: Tokenization, inference, retrieval, and caching happen on your device. - Private by design: Page content, transcripts, files, and summaries never go to cloud APIs. - No account needed: No subscription, API key, telemetry service, or Apogee backend exists. ## At A Glance The table below compares Apogee with common cloud-based AI extensions and the discontinued Orbit project from Mozilla. \| Feature or Architecture \| Apogee \| Cloud AI Extensions \| Mozilla Orbit Project \| \| --- \| --- \| --- \| --- \| \| Local On-Device Inference \| Yes (WebGPU, WASM, Ollama, llama.cpp) \| No (Needs cloud APIs) \| No (Used remote Mistral 7B servers) \| \| Zero API Key Requirement \| Yes (No keys, subscriptions, or accounts) \| No (Needs API keys or paid tiers) \| Yes \| \| Offline Functionality \| Yes (Works offline after initial weight cache) \| No (Needs active internet connection) \| No (Failed without server connection) \| \| Zero Data Transmission \| Yes (Stays on your device) \| No (Uploads full webpage text) \| No (Caches page summaries remotely) \| \| Open Source License \| Yes (MIT License) \| Varies \| Yes \| \| Local Ollama Integration \| Yes (Direct loopback HTTP connection) \| Rare \| No \| \| Local llama.cpp Integration \| Yes (Direct loopback HTTP connection to `llama-server`) \| Rare \| No \| \| Grounded Passage Highlighting \| Yes (Interactive source sentence scroll) \| Rare \| No \| ## What It Can Do - Articles and Web Pages: Clean text extraction uses Readability and site-specific extractors.

Apogee is an AI browser assistant for articles, videos, emails, and more. It runs fully in your browser. It uses your GPU with WebGPU (Chrome, Edge, and other Chromium browsers). It uses your CPU with WebAssembly, which now works everywhere.

WebAssembly is the default on Firefox and an opt-in fallback on Chromium browsers. It helps on machines without WebGPU. No backend, no API keys, no cloud. Install the extension and start.

For power users, Apogee also talks straight to a local Ollama instance over `127.0.0.1`. It also talks to a `llama-server` you run yourself.

> **In short:** Apogee summarizes pages, videos, PDFs, DOCX files, and pasted text locally. It needs no account, API key, backend, or cloud upload.

⭐ If Apogee helps you, [star the repository](https://github.com/darshi1337/apogee). It helps the project reach more contributors.

## Get Started

1. Install Apogee from the [Chrome Web Store](https://chromewebstore.google.com/detail/apogee/pgemlpomhkdcjjjcpnjlebalnfglomog). Or use [Firefox Add-ons](https://addons.mozilla.org/en-US/firefox/addon/apogeeext/).
2. Open a page, video, PDF, or DOCX file, or paste text into the Apogee popup.
3. Pick a summary format and select **Summarize**.

The first in-browser run downloads the picked model. Cached models run offline after that. For larger models, set up [Ollama](https://github.com/darshi1337/apogee/blob/main/OLLAMA.md) or [llama.cpp](https://github.com/darshi1337/apogee/blob/main/LLAMACPP.md) in Settings.

## Why Apogee

The discontinued Orbit project from Mozilla inspired Apogee. Orbit tried browser-based page summarization, but it used central API servers and stored summaries on servers.

Apogee fixes the design and privacy problems of Orbit by staying local-first:

- **Local by default**: Tokenization, inference, retrieval, and caching happen on your device.
- **Private by design**: Page content, transcripts, files, and summaries never go to cloud APIs.
- **No account needed**: No subscription, API key, telemetry service, or Apogee backend exists.

## At A Glance

The table below compares Apogee with common cloud-based AI extensions and the discontinued Orbit project from Mozilla.

| Feature or Architecture | Apogee | Cloud AI Extensions | Mozilla Orbit Project |
| --- | --- | --- | --- |
| Local On-Device Inference | Yes (WebGPU, WASM, Ollama, llama.cpp) | No (Needs cloud APIs) | No (Used remote Mistral 7B servers) |
| Zero API Key Requirement | Yes (No keys, subscriptions, or accounts) | No (Needs API keys or paid tiers) | Yes |
| Offline Functionality | Yes (Works offline after initial weight cache) | No (Needs active internet connection) | No (Failed without server connection) |
| Zero Data Transmission | Yes (Stays on your device) | No (Uploads full webpage text) | No (Caches page summaries remotely) |
| Open Source License | Yes (MIT License) | Varies | Yes |
| Local Ollama Integration | Yes (Direct loopback HTTP connection) | Rare | No |
| Local llama.cpp Integration | Yes (Direct loopback HTTP connection to `llama-server`) | Rare | No |
| Grounded Passage Highlighting | Yes (Interactive source sentence scroll) | Rare | No |

## What It Can Do

- **Articles and Web Pages**: Clean text extraction uses Readability and site-specific extractors. They cover Wikipedia, GitHub, Reddit, Hacker News, Bluesky, Mastodon, Lemmy, Discourse, Stack Overflow, Lobsters, and arXiv.
- **Selected Text**: Select at least 20 characters on a supported page. Use **Selection** in the popup or the browser context menu to summarize only that text. Follow-up Ask questions keep the picked text as their source.
- **YouTube and Bilibili Videos**: Interactive timestamped timelines. Click key moments to jump straight to them in the video.
- **Social Threads**: Apogee parses Bluesky, Reddit, Hacker News, Mastodon, Lemmy, Discourse, and other discussion sites into structured Markdown. It keeps author, score, and reply order.
- **Local documents and text**: Pick or drag PDF, DOCX, TXT, Markdown, JSON, or HTML files into the popup, or paste text directly.
- **Ask Q&A with Smart Retrieval**: Apogee matches passages locally. You can ask about long documents without losing context.
- **Grounding and Sentence Highlighting**: Click any summary bullet to scroll the page straight to the source passage on Chromium browsers.
- **Persistent Chrome Side Panel**: Keep the summary or Ask view open next to the page while you browse.
- **Light and dark themes**: Change themes from the home and summary headers.
- **Custom Standing Instructions**: Set your own prompt guidance such as simple explanations or technical summaries.
- **Per-Page Focus Keywords**: Enter an optional topic or keyword (up to 200 characters) in the **Focus on... (optional)** field (located below the response format selector in the home view) before summarizing articles, PDFs, DOCX files, or pasted text to steer emphasis toward specific themes without inventing facts. The input is hidden on video, discussion (Hacker News, Reddit, Stack Overflow), and multi-tab pages.
- **Multi-Language Translation**: Summarize pages into 32 target languages with the default Helsinki-NLP Opus-MT engine or direct LLM translation.
