	Claude Agent SDK S	Granola S	Claude Code S	Devin A
Tagline	Anthropic's SDK for building your own agents on Claude.	Meeting notes that don't suck. Runs locally, no bot joins.	Anthropic's CLI agent. Opus-powered, operates on your repo directly.	Cognition Labs' autonomous coding engineer.
Category	Agents	Meetings	Coding	Agents
Pricing	API usage + SDK is free	Free + $18/mo	Part of Claude Pro/Max/Team plans	$500/mo
Best for	Developers building custom agents for their own company/product.	Founders, execs, consultants who live in calls.	Developers who want an agent, not autocomplete. Large refactors, tests, docs.	Engineering teams offloading tickets. Ops/platform work.
Strengths	Production-grade agent primitives Built on Claude (best reasoning) Full control — build exactly what you need	No bot in the call — runs on your Mac Strong templates Fast summaries	Runs locally, edits your actual files Strong on large codebases with 1M context Great at multi-step tasks	Works like an engineer — takes Slack tasks, opens PRs Handles multi-hour engineering work Reports back with what it did
Weaknesses	Developer-only You build the UI	Mac-only Single-user by design	Terminal-based — learning curve Can't be used without Claude subscription	Expensive Best for well-scoped tasks Not for solo hobbyists
Kai's verdict	S-tier for builders. The right primitives. What Kai is built on under the hood.	S-tier. Category-defining UX. If you take notes in meetings, switch this week.	S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.	A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
