## Elephas

Elephas is built for the kind of work that should never be pasted into a general chatbot: contracts, client files, policies, research notes and reports. Instead of uploading documents to a cloud service, you point Elephas at files or entire folders on your machine. It reads and indexes them locally, then lets you ask questions in everyday language. Every answer comes with a source reference, so you can open the quoted passage and check it against the original page, slide or sheet.

The privacy model is the core of the product. Documents, the search index and your chats stay on your computer in an encrypted database. When you ask a question, personal details such as names, emails and phone numbers are masked before the request leaves the device, and you can inspect exactly what was hidden under each answer. You also choose where answers are generated - the default Elephas gateway, your own API key for OpenAI, Claude or Gemini, or a local model that runs entirely on your machine with nothing sent anywhere.

Elephas supports documents in English, German, Spanish, French, Japanese and Chinese, with cross-language search, and ships as a macOS and Windows desktop app. A team tier lets an organisation put shared contracts and policies into a common Brain with role-based access, private per-person chats and end-to-end encrypted sync. Pricing is a 7-day free trial with no card required, followed by individual plans and a Teams option at $29 per person per month with no minimum team size.

**Pricing & Plans:** Free 7-day trial with no credit card required. After the trial, individual subscription plans apply, and Elephas Teams is priced at $29 per person per month with no minimum team size.

- **Local document indexing:** Files, folders, PDFs, Word documents, spreadsheets, slides and scans are read and indexed on your own computer rather than uploaded to a third-party service.
- **Answers with sources:** Every response cites the underlying file plus the page, slide or sheet it came from, so you can open and verify the passage yourself.
- **Personal detail masking:** Names, email addresses and phone numbers are hidden before a question leaves your device, and you can view exactly what was masked under each answer.
- **Choice of AI engine:** Use the default Elephas gateway, plug in your own OpenAI, Claude or Gemini API key, or download a local model so answers are generated on your computer with nothing sent.
- **Shared team Brains:** Invite teammates to a common Brain with manager, contributor or reader roles, keep individual chats private, and sync through end-to-end encryption.

**Strengths:** Documents, index and chats stay on your own machine in an encrypted local database; Every answer cites the exact file and page, making verification fast; You choose the AI backend, including fully local generation with nothing sent; Cross-language search across six languages without a language setting

**Limitations:** Desktop-only: there is no browser version, so you need macOS or Windows; Answers still travel to a cloud model unless you pick local generation, and cloud requests are not end-to-end encrypted; Automatic masking of personal details can miss things, so answers should still be reviewed

## CielChan (phasma.ai)

CielChan is a local-first desktop companion rather than a web chatbot. Everything — conversation, memory, and voice — runs on your own PC, so there are no accounts, no API keys, and no subscription. The free version covers voice and text chat, companion memory, and an animated avatar with lip sync. The Plus tier, a one-time payment, unlocks system and audio awareness, advanced voice options, custom VRM avatars and models, multiplayer rooms, a TXT/EPUB book reader, minigames, and local vision for images and screenshots.

Beyond conversation, CielChan bundles utility: timed focus sessions, quick tasks and notes, reminders, ambient soundscapes, and bridges into live-stream chats on TikTok, YouTube, and Twitch. She can react to whatever you are doing on screen with subtle contextual comments, and advanced users can load custom GGUF models to control how she thinks, plus swap in their own VRM avatars. Multiplayer shared spaces let users and companions chat, interact, or run debate sessions together.

Two things are worth stating plainly for anyone who arrived here expecting the older product. First, this is a Windows application with meaningful system requirements (Windows 10/11, 8–16 GB RAM, around 28 GB of disk space), packaged as a download rather than a browser tool. Second, the phasma.ai domain formerly hosted Phasma, an AI writing and coding editor for document processing, translation, and summarization; the site now presents CielChan instead, and it is unclear whether Phasma is still maintained elsewhere.

**Pricing & Plans:** Free version available (voice and text chat, memory, animated avatar, no setup). CielChan Plus is a one-time $7.99 purchase (current version shown as 1.9.7) unlocking system/audio awareness, advanced voice options, custom VRM and model support, multiplayer rooms, book reader, minigames, and local vision. No subscriptions. Free version also distributable via itch.io, with Plus available on Steam or itch.io.

- **Offline voice and text conversation:** Natural two-way voice chat plus full text chat, all processed locally on your PC with no accounts, API keys, or data leaving your machine.
- **Persistent memory and evolving personality:** Ciel remembers who you are and your past conversations, becoming more familiar the more time you spend together.
- **Animated VRM avatar with context awareness:** An expressive avatar with emotions, gestures, and lip sync that optionally reacts to your apps, media, and activity with subtle comments.
- **Productivity and companion tools:** Focus sessions, quick tasks and notes, reminders, ambient soundscapes, and a TXT/EPUB book reader with narration — plus minigames like Tic-Tac-Toe.
- **Live chat bridges and multiplayer rooms:** Connect to TikTok, YouTube, Twitch, and Discord chats so Ciel can interact with your live audience, and join shared rooms for companion interactions or debates.

**Strengths:** Runs 100% offline with no accounts, API keys, or subscriptions — strong privacy posture; One-time $7.99 Plus upgrade with a genuinely usable free tier; Rich feature set beyond chat: focus tools, book reader, stream bridges, local vision, custom models; Extensive customization through custom GGUF models, VRM avatars, and personality controls

**Limitations:** Windows-only and fairly demanding (around 28 GB of storage, 8–16 GB RAM); Several headline features (system awareness, custom models, multiplayer, book reader) require the paid Plus tier; This domain previously hosted a different product (Phasma writing/coding editor), which makes older listings misleading; Heavy local AI inference benefits from a dedicated GPU for best performance
