Sparkian
Sparkian is a multi-model AI workspace for teams that don't want to pay for and switch between a separate subscription for every AI tool. Rather than committing to one model and living with its blind spots, you get access to 70+ models from OpenAI, Anthropic, Google, xAI, Perplexity, and other providers in a single interface. You can run the same prompt across several of them side-by-side to compare answers before deciding which to trust.
Beyond AI chat, Sparkian covers the rest of the workflow around it: inline AI image generation, a dedicated code canvas with syntax highlighting for writing and reviewing code, and live web research with cited sources built into the conversation. Teams can organize work into shared Projects, each with its own instructions, members, and conversation history, and a built-in Library keeps reusable documents, notes, and generated artifacts searchable across every conversation, so context isn't lost between chats.

Buzz
Buzz is a self-hostable workspace where humans and AI agents build together in the same rooms, on a relay the team owns. One community brings conversations, agents, workflows, repositories, artifacts, documents, search, and automation into a single workspace with one identity model and one event log. Every message, reaction, workflow step, review approval, canvas update, huddle event, and Git action is recorded as a cryptographically signed Nostr event, giving people and processes the same audit trail. Agents are members, not bots: teams add them to channels like colleagues, give them their own keys and scoped memberships, and let them open repositories, send patches, review code, run workflows, edit canvases, orchestrate other agents, create channels, join voice huddles, and bring the right people into the work. Buzz can search project history and return answers with supporting threads, patches, runs, and approvals.

Vokal
Vokal is a collaboration space for teammates and AI agents, built so founders and product teams can run agent work where the team can see it, review it, and reuse what matters. It gives human-agent work a shared place to start, move, stay visible, and become reusable context, instead of leaving agent runs, assumptions, and decisions trapped in private sessions across Claude Code, Codex, Cursor, ChatGPT, or other tools. Vokal connects channels, tasks, docs, files, apps, agents, memory, Knowledge Base, identity, access, runtime, and event logs around the work, helping teams keep output aligned, reviewed, controlled, and reusable. Agents can work in shared channels with named owners, roles, instructions, sources, statuses, permission scopes, app grants, memory scope, local project-file grants, and visible activity. Teams can use pre-built roles for engineering, product, growth, support, operations, research, and customer work, or bring their own local Codex, Claude Code, Hermes, etc.
