## Missive

Missive was built around a simple observation: email was designed for individuals, but most businesses run on shared inboxes that several people need to work on together. Missive turns those inboxes into team workspaces. Every email becomes a conversation where colleagues can discuss the reply internally, assign ownership, and see who is handling what. Team inboxes, shared tasks, private notes, and tags replace forwarded messages and side-channel chat apps, keeping context attached to the message it belongs to.

The platform is a full email client as well, supporting Gmail and Google Workspace, Microsoft 365 and Outlook, IMAP, plus SMS and other channels. On top of that sits an automation layer: rules can handle repetitive routing and tagging tasks automatically, and integrations with more than 25 apps such as Stripe and CRMs pull extra context into the inbox. The AI assistant is positioned as a real assistant rather than a generic sidebar, gathering context from connected tools via MCP before drafting a reply.

Missive is popular with small and mid-sized businesses that live in email, including accounting, legal, real estate, logistics, and professional services firms. Customers include teams of 100-200 and above, and the company publishes customer stories, a status page, and a partner program for certified consultants.

**Pricing & Plans:** Missive offers a free trial so teams can invite colleagues and evaluate the product before paying. Paid plans are subscription-based per user, with tiers determined by team size and required features. Exact rates are published on the Missive pricing page.

- **Shared team inboxes:** Let multiple people work the same inbox with clear assignment, internal statuses, and visibility into who is answering what.
- **Internal conversation on emails:** Discuss and prepare replies inside the email thread itself, so context stays attached and nobody is left out of the loop.
- **Tasks and workload visibility:** Turn any email into an assigned task and see what each teammate is working on today, tomorrow, and next week.
- **Automations and rules:** Automate repetitive routing, tagging, and follow-up with rules, rule templates, and workflow automations.
- **AI assistant and integrations:** An AI assistant that gathers context from connected tools via MCP, plus integrations with 25+ apps including Stripe and CRMs.

**Strengths:** Turns shared inboxes into genuinely collaborative workspaces with internal chat; Combines email, tasks, automations, and integrations in one client; AI assistant pulls context from connected tools rather than acting as a generic sidebar; Strong fit for small and mid-sized teams that run on email

**Limitations:** Pricing is per-user and scales up with larger teams; The depth of features can be more than a very small team needs

## 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
