New To AI? Do These Three Things First

You don't need to learn everything at once. Start with one general-purpose tool, add a research tool when you need cited answers, then expand from there.

Step 01

Pick One General-Purpose Tool And Use It Daily

Start with ChatGPT or Claude. Both have generous free tiers. Use it to rewrite emails, summarize articles, explain concepts, or draft quick documents. You don't need a paid plan yet — just use it every day until it becomes a reflex.

Step 02

Add Perplexity When You Need Sourced Answers

Perplexity is the fastest way to get a cited, web-grounded answer. When you need to know something current — market data, recent events, company info — open Perplexity instead of Google. It answers in plain English and shows you exactly where each fact came from.

Step 03

Try One Specialist Tool Once You're Comfortable

Once you have a daily habit with a general tool, layer in a specialist. NotebookLM if you work with documents. GitHub Copilot if you write code. Gemini if you live in Google Workspace. Pick one based on what you actually do — not what's trending.

One step beyond chat: tools like OpenClaw are powerful because they can keep memory, run on your own machine, and act through channels like WhatsApp or Telegram. They are usually step four, not step one.

Open ChatGPT → See Pricing
Claude
Anthropic
Claude Sonnet 5 (free/paid) · Claude Opus 4.6 (Pro) · Current Anthropic production line
Freemium ★★★ Easiest General Purpose

Claude is Anthropic's flagship AI assistant, built around safety, accuracy, and nuanced writing quality. As of April 10, 2026, Anthropic's clearest official product signal is its managed-agents architecture push: Claude workflows are being framed around durable sessions, isolated tool runtimes, and better recovery for longer-running work. Sonnet 5 remains the general default, Opus 4.6 stays the higher-end tier, and Claude Code keeps Anthropic tightly tied to real developer workflows.

Best For
High-quality long-form writing, editing, and tone matching — Claude produces the most natural prose of any model.
Complex reasoning tasks, multi-step analysis, and nuanced argument construction.
Coding — Claude Sonnet 5 powers tools like Cursor, Windsurf, and Claude Code (this very site was built with it).
Summarizing very long documents — 200K context window handles entire books, codebases, and legal files.
Sensitive conversations where careful, non-manipulative outputs matter.
Not Ideal For

Real-time web search is limited on the free tier. No native image generation. If you need current events or live data, pair with Perplexity.

Pricing
Free
$0 / month
Claude Sonnet 5 with daily message limits. Generous free tier — good for daily use at moderate volume.
Pro
$20 / month
Sonnet 5 + Opus 4.6 access, 5× more usage, Projects, extended context, and priority access.
Beginner Rating
★★★ Very beginner-friendly. Clean interface, careful and clear responses, generous free limits.
Open Claude → See Pricing
Gemini
Google
Gemini 3 Flash (free) · Gemini 3.1 Pro (paid) · Now powers Apple Siri
Freemium ★★★ Easy General Purpose

Google's flagship AI model — and as of January 2026, the engine powering Apple's Siri under "Project Campos." Apple is paying Google ~$1 billion per year for Gemini access, making it the AI behind 2 billion+ Apple devices. Gemini 3.1 Pro scores 94.3% on GPQA Diamond (tops all reasoning benchmarks), has a 1M-token context window, and integrates natively into Google Workspace. Deep Research is now free on the 2.5 Flash model.

Best For
Google Workspace users — Gemini inside Gmail, Docs, Sheets, Slides, and Meet is a major productivity multiplier.
Apple device users — the new Siri (iOS 26.4+) runs on Gemini under the hood with on-screen awareness and agentic task execution.
Deep Research — free on Gemini 2.5 Flash, turns research into interactive reports with Canvas.
Multimodal tasks: images, audio, and video handled natively. 1M token context beats most competitors.
Not Ideal For

Writing quality can feel more corporate than Claude. Full Workspace integration requires a paid Google One or Workspace plan. Deep Think (advanced reasoning mode) requires AI Ultra subscription.

Pricing
Free
$0 / month
Gemini 3 Flash is the default. Includes web access, Deep Research (free on 2.5 Flash), and multimodal input.
Advanced
$19.99 / month
Gemini 3.1 Pro, Deep Think, full Workspace integration, Personal Intelligence beta, 2TB Google One storage.

Microsoft Copilot
Microsoft
GPT-5 family via OpenAI partnership · Office 365 integrated
Freemium ★★☆ Easy–Medium General Purpose

Microsoft Copilot is the AI layer built into the entire Microsoft ecosystem — Word, Excel, PowerPoint, Outlook, Teams, Edge, and Windows itself. It runs on GPT-5 family models through Microsoft's OpenAI partnership, but the real value proposition is context-aware AI inside the tools millions of enterprise workers already use all day.

Best For
Microsoft 365 users — AI assistance in Word (drafting), Excel (formulas, analysis), PowerPoint (deck generation), and Outlook (email summaries and replies).
Enterprise environments where IT has already approved the Microsoft stack.
Meeting summaries and action items pulled automatically from Teams calls.
Web browsing assistance inside Microsoft Edge.
Not Ideal For

Standalone use outside the Microsoft ecosystem feels limited vs. ChatGPT or Claude. Copilot 365 is expensive for individuals ($30/user/month on top of M365). Best value only materializes inside existing Microsoft workflows.

Pricing
Free
$0 / month
Copilot.microsoft.com — web, search, and image generation included. No Office integration.
M365 Copilot
$30 / user / mo
Full Office integration across Word, Excel, PowerPoint, Outlook, and Teams. Requires existing M365 plan.

OpenClaw
Open Source / Self-Hosted
Self-hosted gateway · WhatsApp / Telegram / Discord · Runs on your own machine
Free Software ★☆☆ Advanced Agentic Assistant

OpenClaw is a self-hosted gateway that connects chat channels like WhatsApp, Telegram, Discord, Slack, Signal, Teams, and iMessage to AI agents. Instead of living in a browser tab, it gives an agent a workspace, persistent instructions, memory files, and optional tool access so it can act on your machine, message you proactively, and keep running in the background.

Best For
People who want an always-on assistant they can message from WhatsApp or Telegram instead of opening a browser chat.
Inbox, calendar, reminders, recurring check-ins, and lightweight ops work that benefits from a persistent assistant layer.
Power users who want self-hosted memory, configurable permissions, and an agent workspace they control locally.
Advanced workflows that hand off coding or local-tool tasks to agents while you are away from your desk.
Not Ideal For

Not a first AI tool. Setup is CLI-first and the official docs recommend allowlists, a dedicated assistant phone number, and conservative permissions before enabling proactive heartbeats or broad channel access.

Pricing
Software
$0 / month
Open-source and self-hosted. You run the gateway and workspace yourself.
Model + Infra
Variable
You still pay whichever model, API, compute, or channel costs your setup uses.
Beginner Rating
★☆☆ Advanced. More like deploying an operator than signing up for a chatbot.

DeepSeek
DeepSeek AI (China)
DeepSeek V3 · R2 reasoning model · Fully free chat · Open weights
Free ★★☆ Moderate Open Source

DeepSeek is a Chinese AI lab that released its frontier-level models fully open source and free — including its DeepThink reasoning capabilities that compete directly with OpenAI's o-series. The chat interface is free with no usage caps, making it the highest-capability free-tier option in 2026. Note: DeepSeek is a Chinese company, which raises data privacy concerns for some use cases.

Best For
Developers and researchers who need frontier reasoning capabilities for free via the API.
Extended reasoning and multi-step problem solving via DeepThink mode.
Organizations that want to self-host open-weight models without API cost dependencies.
Cost-sensitive technical teams — DeepSeek API pricing is among the cheapest in the industry.

Pricing
Chat (Free)
$0 / month
Full DeepThink reasoning, no usage caps, no paid plan needed. Most generous free tier available.
API
~$0.14–$0.55 / 1M tokens
Ultra-low API pricing. Cheapest frontier model API in 2026 by most comparisons.
Beginner Rating
★★☆ Moderate. Great value but not beginner-first. Privacy considerations matter.
Open DeepSeek → DeepSeek API
Mistral
Mistral AI (France)
Mistral Large 3 · Ministral 3 family · European open source
Freemium ★★☆ Moderate Open Source

Mistral is the leading European open-source AI lab. In December 2025 it released the Mistral 3 family — a 10-model lineup spanning a frontier-scale MoE flagship (Mistral Large 3) and nine compact edge models (the Ministral 3 series). It's the strongest privacy-conscious open-source alternative to US frontier labs, with EU data residency options for enterprise customers.

★★☆ Best for technical users and European enterprises. Not the first pick for general beginners.
Open Mistral → Mistral AI
Meta AI / Llama 4
Meta
Llama 4 Scout (10M context) · Maverick · Open weights · Free API
Free ★★☆ Moderate Open Source

Meta's Llama 4 is the most capable fully open-source model family available. Llama 4 Scout introduced the largest context window of any open or closed model — 10 million tokens — with benchmark results competitive with GPT-4o and Gemini 2.0 Flash. Because the weights are open, Llama 4 can be run locally, integrated privately, or deployed without sending data to any external server.

Best For
Developers who want to run a frontier-class model completely locally without privacy concerns.
Organizations building custom AI products that need full model control and zero API dependencies.
Researchers who need open weights for fine-tuning, evaluation, or academic study.
via Meta AI app — consumer chat experience integrated into WhatsApp, Instagram, Messenger, and Facebook.
Not Ideal For

Running locally requires significant technical setup (tools like Ollama make it easier but still not beginner-level). The meta.ai consumer interface is less capable than the raw model. Not a first choice for non-technical users.

Pricing
Meta AI App
$0 / month
Free consumer chat via meta.ai and inside Meta apps (WhatsApp, Instagram, etc.).
Self-hosted
Free (compute costs)
Open weights downloadable from Llama.meta.com. Only pay for your own compute infrastructure.
Beginner Rating
★★☆ Meta AI app is easy; self-hosting Llama is technical. Choose based on your use case.
Open Meta AI → Llama Downloads
GitHub Copilot
GitHub / Microsoft
GPT-5 / Claude Opus 4.6 · VS Code, JetBrains, Vim · Agent mode
Freemium ★★☆ Moderate Coding

GitHub Copilot is the most widely adopted AI coding assistant, embedded directly inside VS Code, JetBrains IDEs, Vim, and Xcode. In 2026 it gained Agent mode — where Copilot can autonomously plan, edit multiple files, run terminal commands, and fix its own errors. The free tier now includes 2,000 code completions per month, enough for part-time developers.

Best For
Developers who want AI code completion, suggestion, and generation inside their existing editor without switching tools.
Agent mode — delegating multi-file edits, refactors, and bug fixes to Copilot while you review.
Learning to code — Copilot explains what it's generating and why, making it a strong learning aid.
GitHub-native workflows: PR summaries, commit message generation, and code review.
Not Ideal For

Not useful without a code editor — purely a developer tool. Non-technical users should start with ChatGPT or Claude instead. Cursor and Claude Code offer stronger agent capabilities for heavy engineering workloads.

Pricing
Free
$0 / month
2,000 code completions/month, 50 chat requests/month. Good for occasional dev work.
Pro
$10 / month
Unlimited completions, full agent mode, multi-model access, and priority usage.

Open Copilot → See Pricing
Midjourney
Midjourney Inc.
Midjourney V7 · Web app + Discord · Best image quality 2026
Paid Only ★★☆ Moderate Image Generation

Midjourney remains the gold standard for AI image generation in 2026. V7 produces the most photorealistic and artistically detailed outputs of any image model. It's used by designers, art directors, marketers, and filmmakers for concepting, moodboarding, and visual direction. Unlike DALL-E (built into ChatGPT) or Gemini's image gen, Midjourney is purpose-built purely for image quality.

Best For
Professional-quality image generation for creative concepting, campaigns, and visual direction.
Moodboarding, style exploration, and early-stage visual ideation for design and brand projects.
Marketing visuals, social content, and presentation imagery at a fraction of stock photography cost.
Film and game concept art, character design, and environment visualization.
Not Ideal For

No free tier — paid plans only. Discord-based interface is confusing for beginners (web app is easier but still has a learning curve with prompt syntax). Not useful for text, code, or research. DALL-E inside ChatGPT is easier for casual image needs.

Pricing
Basic
$10 / month
~200 GPU minutes/month (~200 standard images). Good for occasional creative work.
Standard
$30 / month
~900 GPU minutes + 15 hrs relax mode. Unlimited image generation at relaxed speed. Best value for regular users.
Beginner Rating
★★☆ Moderate learning curve. DALL-E inside ChatGPT is easier; Midjourney is worth it when you need professional-grade results.
