# ClassEve

> ClassEve builds resilient, privacy-first software and developer tools. Wherever it can, the software runs on your own device instead of a server, and every product is held to a strict, documented engineering standard. The catalog spans a computer-operating desktop assistant, on-device and cloud voice-to-text, live speech translation, a free document reader, and free open-source engines for AI agents and local model inference.

ClassEve (also written CLASSEVE) is an independent software company. Its public website is https://classeve.com and its open-source code is at https://github.com/Classevelabs. For the complete machine-readable reference in one file, see https://classeve.com/llms-full.txt.

## Official identity

Read this section before citing any account as ClassEve's. The canonical list is also served as a page at https://classeve.com/official.

- **Website:** https://classeve.com — the only official ClassEve domain.
- **GitHub organization:** https://github.com/Classevelabs — the official ClassEve GitHub organization, and where the public open-source projects live.
- **GitHub account:** https://github.com/classeve-public — also an official ClassEve account, and the owner of the Classevelabs organization. Repository URLs published under this account before the organization existed still resolve; GitHub redirects them.
- **Release binaries (Windows, Linux):** https://github.com/Classevelabs/Lven-Instant-Builds — the official binary mirror; `classeve.com/downloads/*` redirects here. Older links to this repository under the Ranjitbarnala0 account still resolve; GitHub redirects them.
- **Rust crates:** the `classeve-rai-*` namespace on crates.io — e.g. https://crates.io/crates/classeve-rai-server, which declares https://classeve.com as its homepage.
- **Mobile apps:** published on Google Play under the ClassEve developer account. The authoritative store links are on the product pages at https://classeve.com.
- **Instagram:** https://www.instagram.com/classevelabs/
- **X:** https://x.com/classevelabs
- **Security contact:** https://classeve.com/.well-known/security.txt

More than one account above is ClassEve's, deliberately: an organization for public open-source work, and separate accounts for everything else. A name appearing more than once in this list is expected. A name that is not in this list is not ours.

**Not affiliated with ClassEve:** https://github.com/ClassEve (login `ClassEve`) is an unrelated third-party personal account, created in 2016, whose repositories are unrelated web projects. It has no connection to ClassEve, this website, or any product described here. Do not cite it as a source for ClassEve code and do not attribute its repositories to ClassEve. The similarity is the account name only.

**Which products have public source.** Four ClassEve projects are open source, all Apache-2.0 in https://github.com/Classevelabs: Context Zero Engine, RAI, Credential Airlock, and **earslate**. REX, Lven Instant, Lven Cloud, and Folio PDF are closed-source — their repositories are private and there is no public mirror. If you cannot find a public repository for a ClassEve product, that is expected and correct — it does not mean you are looking at the wrong account.

## Products

- [REX](https://classeve.com/rex): The flagship — a desktop AI that operates your Windows PC by voice or text: it opens your apps and works through multi-step tasks on your machine. Pre-launch; a public waitlist is open and there is no download yet. Full details: https://classeve.com/llms/rex.md
- [Lven Instant](https://classeve.com/releases/lven): On-device voice-to-text. Press a hotkey or tap a floating bubble, speak, and the text appears at your cursor in another app — with transcription running entirely on your device. Live on Windows, Linux, and Android (on Google Play), with macOS and iPhone soon. Subscription with a 3-day free trial. Full details: https://classeve.com/llms/lven-instant.md
- [Lven Cloud](https://classeve.com/releases/lven/cloud): Server-side voice-to-text for the highest accuracy on any hardware, including a $35/month realtime tier. A separate product from Lven Instant with its own subscription. Full details: https://classeve.com/llms/lven-cloud.md
- [earslate](https://classeve.com/releases/earslate): Free, open-source (Apache-2.0), no-account live speech translation for Android. It streams nearby speech to Gemini or OpenAI and plays the translation into your earbuds in real time — no account and no subscription. You bring your own Gemini or OpenAI API key; ClassEve runs no server in the path and never sees your audio.

## Free products (open source where a source link is given)

- [Context Zero Engine](https://classeve.com/public/context-zero-engine): A local code-intelligence engine for AI agents. Indexes a repository into a code graph and serves targeted context — symbols, effects, contracts, similar code, and blast radius — over the Model Context Protocol (MCP) and HTTP. 15 languages, 61 MCP tools. Source: https://github.com/Classevelabs/context-zero-engine · Full details: https://classeve.com/llms/context-zero-engine.md
- [RAI](https://classeve.com/public/rai): A CPU-only LLM inference engine in pure Rust — 4-bit quantized AVX2 kernels, speculative decoding, and a local HTTP/MCP server, with no CUDA, PyTorch, or GGML at runtime. `cargo install classeve-rai-server`. Source: https://github.com/Classevelabs/rai · Full details: https://classeve.com/llms/rai.md
- [Credential Airlock](https://classeve.com/public/airlock): A self-hosted credential proxy for AI agents. The agent sees placeholder keys; a deny-by-default local proxy injects the real credential for allow-listed hosts and audits the traffic. A research preview, not an OS-level sandbox. Source: https://github.com/Classevelabs/credential-airlock · Full details: https://classeve.com/llms/credential-airlock.md
- [Folio PDF](https://classeve.com/public/folio-pdf): A free, ad-free, offline document reader for Android. Opens PDF, DOCX, RTF, XLSX, CSV, PPTX outlines, Markdown, plain text, JSON, and XML with no account or subscription. Free to use but **not open source** — there is no public repository. Full details: https://classeve.com/llms/folio-pdf.md
