## Consensus

Consensus works like a scholarly search engine supercharged by AI. Instead of returning a flat list of PDFs, you ask a natural-language research question and Consensus extracts claims from relevant papers, then shows you what the studies actually find. A Consensus Meter summarizes the weight of evidence for yes/no questions, so you can see at a glance whether scientists largely agree, disagree, or remain divided.

The platform indexes hundreds of millions of peer-reviewed papers spanning medicine, biology, psychology, economics and more. Answers link straight back to the source studies, and you can filter by study design, journal quality, sample size and publication year to separate stronger evidence from weaker signals. Features like Deep Search, Topic Synthesis and Skills let researchers build a working knowledge base over time rather than starting from scratch on every query.

Consensus is designed for researchers, clinicians, students and analysts who need trustworthy signals from the scientific record without drowning in irrelevant results. A free tier gives limited AI-powered searches each month, while paid plans unlock unlimited use, advanced filters and deeper synthesis.

**Pricing & Plans:** Freemium. A free tier offers a limited number of AI-powered searches per month; paid individual plans unlock unlimited searches and advanced research features, with discounted student pricing and team/enterprise options.

- **Evidence-grounded answers:** Ask a research question in plain language and get answers synthesized from peer-reviewed studies, with each claim linked to its source paper.
- **Consensus Meter:** A visual summary shows how the scientific literature leans on a yes/no question, indicating agreement, disagreement or mixed evidence.
- **Powerful filters:** Narrow results by study design, sample size, journal quality, publication year and more to prioritize high-quality evidence.
- **Topic synthesis and Deep Search:** Aggregate findings across many studies into structured summaries that map what is known and where the gaps are.
- **Research workspace:** Save papers, organize sources and build a persistent knowledge base for literature reviews and ongoing projects.

**Strengths:** Answers cite real peer-reviewed papers, so claims are verifiable; Consensus Meter makes it easy to gauge scientific agreement at a glance; Rich filters help separate high-quality evidence from weaker studies; Fast, clean interface designed around research workflows

**Limitations:** Free tier caps the number of AI-assisted searches per month; Coverage is strongest for STEM and health fields, lighter for some humanities topics; It guides you toward sources but is not a substitute for reading full papers

## 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
