Vendor-authored guide, rewritten October 5, 2026
Choose an AI platform by the work you need to do
The right AI platform depends on whether you need a native-provider app, a multi-model workspace, a workplace integration or a developer API. This vendor-authored guide compares those choices by actual workload and documents what was checked. It should help you identify a shortlist, not declare one universal winner.
Publisher interest
ZeroTwo publishes this guide and sells one of the products in it. Every product is described by the same rules, there are no scores or rankings, and each plan detail was read from the vendor's own page in October 2026 and is linked in the table.

Model quality and application capability are different things. Pick the shape of product first, then compare within it.
Native model-provider apps
One lab's models inside that lab's own app, with its newest features arriving there first: Custom GPTs and Codex in ChatGPT, Claude Code and Projects on Claude Pro, Gemini inside Gmail and Docs on Google AI plans.
- Fits when
- Your work lives in one vendor's models and you want its app features.
- Trade-off
- You cannot put another lab's models in the same thread, and each app's limits are its own.
- ChatGPT
- Claude
- Gemini
- P
Multi-model workspaces
One app, models from several labs. ZeroTwo offers 60+ models from providers including OpenAI, Anthropic, Google and xAI. Poe's home page names GPT, Claude, Gemini, Grok and Kimi models and says there are thousands of others.
- Fits when
- You move between labs, or want files and agents kept in one place.
- Trade-off
- You get the workspace's features, not every feature of each lab's own app. ZeroTwo routes to upstream providers, so a provider outage or model retirement reaches it too.
- ZeroTwo
- Poe
Suite-native assistants
AI inside the apps where the documents already live: Word, Excel, PowerPoint, Outlook and Teams for Microsoft 365 Copilot; Gmail and Docs for Gemini on Google AI plans.
- Fits when
- Most of your work is already in Microsoft 365 or Google Workspace.
- Trade-off
- Tied to the suite. Microsoft 365 Copilot is an add-on that needs a qualifying Microsoft 365 plan and may not be available in every market, per Microsoft's pricing page.
- Microsoft 365 Copilot
- Gemini in Gmail and Docs
Developer gateways and APIs
OpenRouter describes access to hundreds of models through a single API endpoint, with automatic fallbacks. It is built for developers calling models from code, as are the providers' own APIs.
- Fits when
- You are building software that calls models and want one endpoint.
- Trade-off
- You supply the interface, memory and file handling yourself. Multi-provider routing is not unique to ZeroTwo; it is what this category does.

What this guide is, and what it is not
Who wrote it, what was read, and what was left out.
Our interest
ZeroTwo publishes this guide and sells one of the products in it, a multi-model workspace. That is why it names cases where another product is the better pick, and why it carries no scores.
What we checked
Plan pages and docs from each vendor, read in October 2026: ChatGPT pricing, Claude pricing, Gemini subscriptions, Microsoft Copilot business pricing, the OpenRouter quickstart and the Poe home page. ZeroTwo's own figures come from its plan catalog.
What we did not do
We did not run benchmarks, score the products or sample reliability, and we did not read Poe's plan prices. An earlier version of this page carried numeric scores; they were removed because the per-criterion evidence was never published.

Prices are US list prices before tax, read from the linked vendor pages in October 2026. Vendors change plans without notice, so confirm on their page before you buy.
Data controls
Read the policy for the plan you would use, not the product's marketing page. OpenAI's pricing page lists an opt-out for model training on each individual plan. Claude's lists an opt-out on individual plans and no training by default on Team and Enterprise. ZeroTwo's terms are on its privacy page.
ZeroTwo privacy policyUsage limits and cost
Unlimited rarely means unlimited work. Claude documents 5-hour windows plus weekly limits, Gemini refreshes every 5 hours up to a weekly limit, ChatGPT says limits apply, and ZeroTwo meters paid work in monthly credits and free Auto requests. Compare what a month of your own work consumes.
compare plan and usage costsIntegration path
Suite assistants win when the documents already live in the suite. For everything else, compare connector lists for the three or four tools you cannot give up before comparing models.
ZeroTwo connectorsModel versus platform
Models are one layer; projects, memory, agents and file handling are another. Reaching a lab's model through a workspace does not bring that lab's own app features with it, and a strong model in a thin app can lose to a modest one in a better workflow.
Shortlists for distinct workloads
Conditional recommendations, including the cases where a competitor is the better first stop.
Long documents and polished writing in one house style
Start with
A native app from the lab whose model you already prefer
ChatGPT, Claude and Gemini each ship their own projects, memory and file tools around their models. Add a multi-model workspace if you want to test another lab on the same document.
multi-provider workspace comparisonYou compare models across labs, even occasionally
Start with
A multi-model workspace such as ZeroTwo or Poe
One thread and one bill across providers is the whole point of the category. If one lab clearly covers the work, its own app is the simpler choice.
ZeroTwo agent platformYour team lives in Microsoft 365 or Google Workspace
Start with
The suite assistant: Microsoft 365 Copilot or Gemini on a Google AI plan
The assistant sits where the documents, mail and meetings already are. Add a workspace only for the work that happens outside the suite.
business tools by departmentYou build software that calls models
Start with
A developer gateway such as OpenRouter, or the provider's own API
One endpoint, your own interface, and per-model pricing you can read in the catalog. Keep a chat workspace for quick prompt trials before you wire anything up.
Casual questions on a phone
Start with
The free tier of a native app
Free plans from ChatGPT, Claude and Gemini are listed on their pricing pages and need no comparison exercise. Move to a paid plan only when you hit limits you actually feel.
AI apps by use caseMulti-step file work that ends in a deliverable
Start with
Pilot two or three products with the rubric below
Agent features, file handling and limits differ most here, and a feature table will not tell you which holds up on your files. Count edits and limits hit, not just how good the first answer looks.
Run a pilot and revisit the decision
A feature table cannot tell you which product holds up on your files. One small, scored assignment per product can.
Shortlist two or three
If you are unsure of the category, take one product from each of two categories.
Run one real assignment in each
Same files, same instructions, on the plan you would actually buy.
Score before you compare
Use the rubric below on each result before you read the next one.
Price a month of your own work
Note the allowance each run used and write down the date you checked prices.
Scoring rubric
- Used every file you provided, and said so
- Numbers match the source, with the page or cell named
- Output arrives in the format you need
- Flagged what it could not verify
- Edits needed before you could send it
- Limits hit during the run
Cost worksheet
- Plans you would keep
- Name each plan, not just each vendor.
- List price per month
- Per seat if the plan is per seat. Before tax.
- Extra usage you expect
- Credits, top-ups or API tokens beyond the plan.
- Total per month
- Then divide by the assignments you actually ran.
When to recheck
- A vendor changes plans, prices or limits.
- A model you rely on is retired or replaced.
- Your usage changes enough to hit a limit.
- A data policy changes for your plan.
Update log: October 5, 2026. Rewritten as a category guide. Removed the numeric scorecard and ranking, third-party statistics and a paraphrased quotation with no exact source. Vendor plan details were re-read from vendor pages.
Questions before you choose
Do I need an app, a workspace or an API gateway?
If you only use one lab's models, its own app. If you move between labs, a multi-model workspace. If your documents live in Microsoft 365 or Google Workspace, start with the suite assistant. If you are writing software that calls models, an API gateway or the provider's own API. Many people combine two.
How were products and plans selected?
We picked one or two widely used products per category: ChatGPT, Claude and Gemini as native apps, Microsoft 365 Copilot for suites, ZeroTwo and Poe as multi-model workspaces, and OpenRouter for developers. It is not a market census, and ZeroTwo is our own product. Plans listed are the ones on each vendor's public page.
How do usage limits change total cost?
Limits decide how much work a plan covers before you pay more or wait. Vendors meter differently, with credits, usage windows or per-token charges, so compare what a month of your own work consumes rather than the sticker price. Price a pilot month before you commit.
Which features come from a model versus the platform?
The model supplies the reasoning and writing. The platform supplies projects, memory, agents, file handling, connectors and limits. Reaching a lab's model through a workspace does not bring that lab's own app features with it.
When were prices and data policies checked?
Vendor plan pages were read in October 2026 and are linked in the comparison table. Prices, plans and policies change without notice, so confirm on the vendor's page before you buy. This page makes no guarantee that any figure is current.
