1.
Claude
Best for: Client deliverables, long documents, and building things
Pricing: Free tier, flat monthly Pro, plus usage-based API for anything you automate
Claude is the strongest model for the work agencies actually bill for: long-form writing, editing, analysis, and code. It holds huge context, so you can drop an entire brand guide, transcript, or codebase in at once. It also powers Claude Code, which is how a lot of internal tools now get built.
- +Best for long documents and careful writing
- +Huge context window, feed it whole briefs or codebases
- +Powers Claude Code for building internal tools
Watch out: Fewer built-in consumer extras than ChatGPT (no native image generation), so many agencies run both.
2.
ChatGPT
Best for: A general assistant and custom GPTs across the team
Pricing: Free tier, flat monthly Plus/Team per seat, plus API
ChatGPT is the most general and the easiest to get a whole team using. Custom GPTs let you package a repeatable task (a brief writer, a QA checker) and share it. Native image generation and voice make it the broadest single tool.
- +Easiest for a non-technical team to adopt
- +Custom GPTs package repeatable tasks
- +Native image generation and voice
Watch out: Per-seat pricing adds up across a team, and for long, careful writing many prefer Claude.
3.
n8n
Best for: Wiring AI into hands-off workflows you own
Pricing: Flat cloud tiers, or self-host for effectively unlimited executions
AI tools only pay off once they run without you. n8n is the automation backbone that connects Claude or ChatGPT to your real stack (email, CRM, sheets, Slack), so a task runs on a schedule or a trigger instead of someone remembering to prompt. Self-host it and client data stays on your own infrastructure, white-labeled.
- +Turns one-off prompting into automated systems
- +Runs any API and full custom code, no rigid ceiling
- +Self-host, own your data, white-label for clients
Watch out: More setup than a consumer app, which is why agencies usually have it built and maintained for them.
4.
Make
Best for: Visual automation for mid-complexity flows
Pricing: Per operation, free tier to start
Make is the friendlier visual builder for wiring apps and AI together without much code. Good for moderate branching and logic when you want to see the flow on a canvas.
- +Approachable visual builder
- +1500+ connectors
- +Cheaper per run than Zapier
Watch out: Per-operation billing climbs at volume, no self-hosting, and a ceiling on custom logic.
5.
Perplexity
Best for: Research and answers with sources
Pricing: Free tier, flat monthly Pro
Perplexity is the fastest way to get a researched answer with citations you can actually check, which matters for agency work where a claim has to hold up. Good for market scans, competitor checks, and first-draft research.
- +Answers with real, checkable citations
- +Fast for research and market scans
- +Low friction for the whole team
Watch out: It is a research tool, not a builder or an automation layer, so it complements the others rather than replacing them.
6.
Cursor
Best for: Building internal tools and sites faster
Pricing: Free tier, flat monthly Pro per seat
Cursor is an AI code editor that lets a technical person on the team ship internal tools, landing pages, and fixes far faster. Paired with Claude, it is how a small agency builds the software it used to outsource.
- +Big speed-up for anyone who builds
- +Works with the strongest models
- +Good for internal tools and client sites
Watch out: It is for people who write code; non-technical teams get more from the assistants above.
