Free

Cangjie Skill distills books, long videos, and podcasts into callable AI Agent Skills using the RIA-TV++ methodology.

Key features

  • RIA-TV++ Distillation Method: A structured methodology that pulls extractable, verifiable, transferable methodologies out of long-form source material.
  • Multi-Format Ingestion: Works with books, long videos with subtitles or transcripts, podcasts, interviews, speeches, courses, and long articles.
  • Skill Composability: Distilled outputs are independent Agent Skills that can be called individually or composed with other skills.
  • Stress-Test Validation: Every skill is stress-tested so distilled methodology actually holds up in real problem-solving, not just summary form.
  • Platform Compatibility: Runs on Claude Code and OpenClaw, so distilled skills plug directly into existing agent workflows.
  • Video Pipeline Integration: Pairs with a companion video-downloader skill to fetch subtitles, audio transcripts, and key assets before distillation.

Best for

  • Book to Actionable Skill: Turn a business or self-help book into a callable skill that helps you apply its framework during real decisions.
  • Long Video Knowledge Capture: Distill a two-hour interview or Bilibili/YouTube deep dive into a reusable methodology skill.
  • Podcast Methodology Extraction: Convert recurring podcast frameworks into a library of composable agent skills.
  • Course Companion: Package a paid course's methodology into a skill an agent can invoke while the student is doing real work.
  • Personal Knowledge Base for Agents: Build a growing library of methodology skills that your coding agent can call on demand.
  • Team Playbook Distillation: Convert long internal training material into structured, callable skills for teammates.

Freemium

Self-hosted AI agent with long-term memory that spans CLI, chat, SDK and real-world actions, running on open-weight models you host.

Key features

  • Persistent Cross-Surface Memory: Teach the agent something once in the CLI and it already knows it in chat, in the SDK and on a phone call — memory persists per user across sessions and surfaces instead of dying with one login.
  • Self-Hosted Open-Weight Stack: Run the entire agent inside your own walls on your keys, machines and network, using open weights the company hosts or local models through Ollama, so source code never leaves your infrastructure.
  • Proactive Background Operation: The agent is already running rather than waiting to be opened — it monitors what you asked it to watch and hands back only the decision that was actually yours.
  • Approval-Gated Real-World Actions: Control smart-home devices, monitor an inbox around the clock, place phone calls and look up half-remembered contacts, with every action gated behind an explicit approval.
  • 1M-Token Context on Every Tier: A one-million-token context window is included even on the free plan, letting the agent hold an entire repository in mind at once.
  • Model-Agnostic Tiering: Dropstone Fast, Pro and Heavy each run whatever tops the open-weight leaderboards that month rather than being tied to a single lab.
  • Learned Skills: The agent picks up skills it does not yet have, retains them and reuses them without being asked twice, with the skill list growing month over month.
  • Multi-Surface Access: Reach the same agent through the Dropstone CLI, a web dashboard, VS Code / Cursor / Windsurf extensions and Remote MCP connectors, with sandboxed code execution and plan mode before changes apply.

Best for

  • Air-Gapped Engineering Teams: Ship real code with an AI agent while keeping the models, the repository and the network entirely inside company infrastructure.
  • Always-On Inbox Triage: Let the agent watch an inbox around the clock and surface or act on the messages that matter instead of checking it yourself.
  • Terminal-Native Development: Use the CLI agent to generate code, run it in a sandbox and open diffs, with plan mode and approval gates before anything is applied.
  • Personal Operations Automation: Hand off recurring real-world tasks — smart-home control, placing a call, chasing a contact — to an agent that already has your context.
  • Cost-Sensitive Heavy Usage: Get several times more weekly coding usage per dollar than subscription coding CLIs by running on self-hosted open-weight models.
  • Custom Agent Integration: Embed the same memory-backed agent into your own stack through the SDK and Remote MCP connectors.
