LLM Subscription Showdown: ChatGPT vs Claude vs Perplexity

Most people reading this are paying for two, three, or four large language model subscriptions at once. The math is ugly. ChatGPT Plus at $20, Claude Pro at $20, Perplexity Pro at $20, and a Notion AI seat at another $20 adds up to $80 a month, or $960 a year, for tools that overlap far more than their marketing suggests. That number is why I spent several weeks logging which LLM I actually opened, what I used it for, and whether the second and third subscriptions earned their keep. If you want the broader field first, our best AI tools subscription guide for 2026 covers the wider market before you narrow down to chatbots.

Here is how I tested. I paid for all four plans with my own card, no vendor comps, and ran the same eight tasks through each one: a 3,000-word draft, a 60-page PDF summary, a competitor research question, a spreadsheet formula, a code review, a meeting transcript cleanup, an image request, and a quick factual lookup. I also checked public review data. G2’s ChatGPT profile holds roughly 4.6 out of 5 across well over a thousand reviews, and the ratings for the other major assistants sit in a similar band. That tells you something useful. Most people are satisfied with whichever one they picked first, which means satisfaction is a poor guide for choosing.

Timing matters here. Free tiers got genuinely good over the past year, and the paid tiers converged on the same $20 entry price. That combination makes the old advice of stacking tools much weaker than it used to be. Two years ago you needed three subscriptions because no single model could reason, read files, and search the web well. Now one can do all three at a passable level. If you have never audited what you pay for, our walkthrough on how to consolidate AI subscriptions is the practical companion to this comparison.

Below I compare four LLM plans that cover almost every real use case: ChatGPT Plus, Claude Pro, Perplexity Pro, and Notion AI. Each section covers what you actually get for the money, where it falls short, and who should keep paying. Prices move fast, so treat every figure as a starting point and verify on the vendor page before you cancel anything. The goal is not to find the best model. The goal is to stop paying for three models that do the same job.

How Do the Top Options Compare?

Prices reflect publicly listed US rates at the time of writing and change often. Verify current pricing on each vendor’s own page before you cancel or upgrade a plan.

1. ChatGPT Plus , Best for all-round daily use

ChatGPT Plus costs $20 a month and remains the default first subscription for most people. That tier gives you the newest GPT-5 family models with a higher message cap, web browsing, file uploads, image generation, voice mode, and a set number of Deep Research runs each month. OpenAI’s pricing page lays out the tiers, and the gap between Plus and the $200 Pro plan is mostly about volume rather than features. If you hit the Plus limits once a week, you do not need Pro. If you hit them before lunch every day, you probably do.

The reason ChatGPT stays in so many stacks is range. It writes a passable first draft, reads a screenshot, transcribes a voice memo, generates a product mockup, and searches the web without you opening a second tab. One window does the work that used to need three. The tradeoff is that it is rarely the best at any single task. Claude beats it on long-form editing, Perplexity beats it on cited research, and a dedicated image tool beats it on visuals. We broke the head-to-head down in our ChatGPT vs Claude Pro comparison, and the short version is that ChatGPT wins on breadth while losing on depth.

What actually annoys me about Plus: the usage caps move, and OpenAI does not always explain why you got throttled mid-task. Memory is helpful until it is not, because stale facts about your job follow you into unrelated chats. Custom GPTs add more clutter than value for a solo user. Still, at $20 it is the safest single subscription to keep when you only want to keep one. For a solo business owner running a small stack, this is usually the anchor tool.

Key strengths:

• ✅ Breadth: one subscription covers writing, image generation, voice, file analysis, and web search.
• ✅ A genuinely usable free tier, so you can test the workflow before paying.
• ✅ Deep Research and Projects handle multi-step work without adding another tool.
• ✅ The largest third-party support base, so integrations and prompt guides exist everywhere.
• ✅ Voice mode is good enough to replace a separate transcription subscription for short recordings.
• ❌ Usage limits shift without clear notice, which makes heavy workdays frustrating.
• ❌ Memory drags stale context into unrelated conversations more than I would like.
• ❌ Rarely the best option for long documents or research that needs citations.

Who it’s for: Choose ChatGPT Plus if you want one general-purpose assistant and you value range over specialization.

2. Claude Pro , Best for long documents and writing

Claude Pro runs $20 a month, or about $17 a month if you pay annually, with higher tiers at $100 and $200 for heavy users. Anthropic’s site lists the current limits, and the headline number that matters is context: around 200K tokens on standard plans, which is roughly a 500-page book in a single conversation. In practice that means you can paste an entire contract, a full quarter of support tickets, or a long research report and ask questions across all of it without chopping the file into pieces.

The quality difference shows up in editing. Claude returns prose that needs fewer passes, and it follows structural instructions like keep the intro under 80 words without drifting. Artifacts make it easy to iterate on a document or a small app in a side panel. Projects let you pin reference files and instructions so you are not re-explaining your style guide every morning. Our Claude Pro review goes deeper on the workflow side if you want the hands-on version.

Where Claude falls down is anything visual. There is no image generation, the connector list is shorter than ChatGPT’s, and Pro message caps can bite during a long afternoon of revisions. Claude Code is excellent if you write software, but that is a narrower audience than the general chat product. The model also tends to be cautious to a fault, occasionally refusing benign requests that other tools answer without hesitation.

Key strengths:

• ✅ Long context handling is the best of the four for contracts, reports, and transcripts.
• ✅ Writing quality needs noticeably fewer editing passes than the alternatives.
• ✅ Projects and Artifacts keep reference material and drafts organized in one place.
• ✅ Claude Code is a real development tool, not a demo feature bolted onto a chatbot.
• ✅ Annual billing drops the effective price to roughly $17 a month.
• ❌ No image generation, which means keeping a second tool if you make visuals.
• ❌ Pro message caps can interrupt heavy revision sessions.
• ❌ Fewer connectors and integrations than ChatGPT, so automation is harder.

Who it’s for: Choose Claude Pro if your day revolves around long documents, editing, or writing that has to sound like a human wrote it.

3. Perplexity Pro , Best for research with sources

Perplexity Pro is $20 a month, with a Max tier at $200 for people who want the top models and higher research limits. The core value is simple: every answer comes with links to the sources it used. Perplexity’s own site lists the plan details, and Pro gives you roughly 300 Pro searches a day, a model picker that lets you route a question to different underlying models, file analysis, and Deep Research runs that produce a cited report rather than a wall of confident text.

The model picker is the feature most people underestimate. Being able to send a math question to one model and a market question to another, without switching subscriptions, quietly replaces a lot of tool-hopping. Spaces let you keep a research thread with its sources attached, which is closer to how actual research works than a chat history. If you mostly use AI to answer questions rather than produce content, this is the strongest $20 in the category. We compared it directly against the big chatbot in our Perplexity vs ChatGPT search breakdown.

The limit is structural. Perplexity is built around giving you an answer, not producing a 2,000-word deliverable. Long-form drafts come out summary-shaped and thin. Citations are usually solid but occasionally point at pages that only partly support the claim, so you still spot-check anything important. Treat it as a research desk, not a writing desk, and it earns its place. Treat it as your only AI subscription and you will be frustrated by the third draft.

Key strengths:

• ✅ Source links on nearly every answer, which makes verification fast.
• ✅ The model picker lets you choose the best engine per question.
• ✅ Roughly 300 Pro searches a day covers heavy research without throttling.
• ✅ Deep Research produces cited reports you can hand to a client with light editing.
• ✅ Spaces keep research threads and sources together instead of buried in chat history.
• ❌ Weak at long-form writing, so it cannot replace a drafting tool.
• ❌ Occasional citations only partially support the claim they are attached to.
• ❌ Answer-first format discourages the back-and-forth that good ideation needs.

Who it’s for: Choose Perplexity Pro if your recurring job is finding, checking, and citing information rather than producing finished prose.

4. Notion AI , Best for teams already working in Notion

Notion AI costs $20 per member per month on the annual Business plan, or $24 month to month, and it is also sold as an add-on on lower plans. That per-seat structure is the whole story. One person paying $20 for AI inside their notes is reasonable. Ten people paying $200 a month for the same features is a budget decision that needs a real justification. Notion’s pricing page spells out which plans include AI, and the answer has shifted more than once.

What you get is different from the other three. Notion AI answers questions across your own workspace, so it can pull the answer out of a project doc you wrote eight months ago. It fills database properties automatically, cleans up meeting notes, summarizes long pages, and drafts inside the document you are already editing. For a team whose entire operating system lives in Notion, that context is worth more than a smarter model with no access to your files. We covered the tradeoffs against a simpler setup in our Notion AI vs Obsidian plus Claude piece.

For an individual, the case is weaker. The underlying model is not the sharpest of the four on hard reasoning, AI responses are capped on some plans, and if your notes live in Apple Notes or plain markdown files, you are paying for a workspace you do not use. The other honest downside is switching cost. Once a team builds its docs around AI-generated database fields, moving off Notion gets expensive in ways a subscription comparison will not show you.

Key strengths:

• ✅ Answers come from your own workspace documents, not just the model’s training data.
• ✅ Database autofill and meeting note cleanup save real time on repetitive admin.
• ✅ AI lives inside the document editor, so there is no copy-paste step.
• ✅ Strong fit for teams that already run their operations in Notion.
• ✅ Included in the Business plan rather than billed as a separate tool for many users.
• ❌ Per-seat pricing punishes small teams and solo users at $20 per member monthly.
• ❌ The underlying model is weaker on hard reasoning than Claude or ChatGPT.
• ❌ Only worth it if your notes already live in Notion, which makes switching costly.

Who it’s for: Choose Notion AI only if your team’s documents, notes, and databases already live inside Notion.

How to Build a Minimal LLM Stack

The honest way to decide is to log usage for two weeks before you renew anything. Track which LLM you open first, which one you paste long documents into, and which one you only touch when a specific task shows up. Most people find that one tool accounts for 70 to 80 percent of their sessions. Everything else is a $20 habit.

A minimal stack usually looks like one general model plus one specialist. Keep ChatGPT Plus or Claude Pro as the primary, then add Perplexity Pro only if cited research is a real part of your week. If you write code all day, Claude Max at $100 a month can replace a $20 chat seat and a separate coding assistant at the same time, which is a genuine saving rather than a downgrade.

Teams should run the per-seat math before adding Notion AI. Ten seats on the Business plan is $200 a month billed annually, which is real money for a feature a single $20 ChatGPT seat can partly cover. Give one team access for a month and ask whether anyone used workspace search twice. If the answer is no, you have your decision.

Cancelling is easier than upgrading. Drop the tool you use least, keep the primary for a full month, and see whether you miss the second one. Most people do not. The savings are quiet but they compound, and you can always resubscribe the following month if a real gap shows up.

Frequently Asked Questions

What Should You Remember?

• Start with usage, not features. Log which LLM you open first for two weeks before you renew anything.
• One primary plus one specialist is the most common minimal stack, and it usually costs $40 a month or less.
• ChatGPT Plus at $20 is the safest single subscription if you want range across writing, images, voice, and search.
• Claude Pro at $20 wins when long documents, editing quality, and code review matter more than feature count.
