Chat with ChatGPT, Gemini, Claude, and Grok. Then continue into image, document, presentation, spreadsheet, and file workflows.

ChatGPT

Write, code, summarize, translate, learn, plan, and draft.

Gemini

Fast explanations, study help, and a second opinion.

Claude

Long-context writing, review, and careful reasoning.

Grok

Another perspective for research, critique, and coding.

Image models

Create images and compare visual directions.

File studios

Make docs, slides, spreadsheets, images, and file outputs.

Compare Mode + AI Team

Side-by-side answers and AI collaboration

Compare answers when one model is not enough. Use AI Team when the task needs review and synthesis.

ChatGPT use cases

Start with this tool. Continue in MultipleChat.

Start with the tasks people use ChatGPT for every day. Keep the page simple; move into advanced workflows only when the task needs them.

Write and rewriteEmails, posts, outlines, resumes, notes, and clearer versions of rough text.
Code and debugExplain errors, draft functions, review snippets, and plan implementation steps.
Summarize and learnTurn long text into bullets, explain topics, make study plans, and translate ideas.
Plan and brainstormGenerate ideas, compare options, prepare lists, and organize messy thoughts.
Decision guide

Which workflow should you use?

Start with the simplest mode that solves the job. Move up only when the answer needs judgment, collaboration, or a finished file.

Need speed?Use ChatGPT solo for a first draft, explanation, summary, or code answer.
Need judgment?Use Compare Mode to inspect answers from several models side by side.
Need a stronger answer?Use AI Team to draft, critique, verify, debate, and synthesize.
Need deliverables?Use the studios for documents, slides, spreadsheets, images, and files.

How it works

  1. Upload the file
  2. Ask precisely, ask for references
  3. Recompute with a second model

What opens after login

Upload the spreadsheet to a Project so every model can read it and later questions can build on earlier answers. Ask for sheet and cell references so answers are checkable.

Paid plans add larger files, the latest models, and a generated spreadsheet back out of the analysis.

Chat with a spreadsheet

Choose the right model path

Ask for the working

"Show the formula you used for each column." Makes arithmetic checkable.

Recompute with another model

"Another model produced these figures from the same file. Recompute independently and list differences."

Name the sheet and columns

Ambiguity is where spreadsheet answers go wrong. Say which sheet, which columns, which period.

Get a spreadsheet back

On paid plans, the analysis can come back as a real spreadsheet with the formulas in it.

How MultipleChat compares

ChatGPT is a strong model. MultipleChat is the workflow around it: model access, side-by-side comparison, AI collaboration, file handling, studios, projects, and verification in one place.

MultipleChat compared with ChatGPT alone and typical AI aggregators
Capability ChatGPT alone Typical AI aggregator MultipleChat
Normal ChatGPT tasksStrong for writing, code, summaries, learning, translation, and analysis.Usually depends on the chosen model.Included Do the same core ChatGPT tasks, then continue into broader workflows.
Latest model accessOne provider's model family.Several models, but versions can be unclear.Current paths ChatGPT, Gemini, Claude, Grok, web-search models, and image models in one workspace.
Side-by-side model comparisonManual copy-paste into other tools.Sometimes basic parallel answers.Core feature One prompt, multiple answers, same context.
AI collaborationOne model answers alone.Mostly model switching.AI Team Models can draft, critique, debate, verify, and synthesize one final answer.
Create files from chatGeneric text output, then manual copy into other apps.Often one or two output tools.Studios Documents, presentations, spreadsheets, images, and file-based chat workflows.
Projects and contextMostly chat history.Usually folders or separate chats.Workspace Chats, uploads, project instructions, sources, and history together.

Questions that get reliable answers from a spreadsheet

Name the sheet and the columns. Ask for the formula the model used. Ask for outliers before totals; outliers are where data problems hide. For anything you will put in a report, ask a second model to recompute it from the same file and list the differences, then open the sheet where they differ.

On paid plans the analysis can come back as a real spreadsheet with the formulas in it, which is the version to hand to an accountant or a colleague.

NameSheet, columns, period.
ShowThe formula used.
RecomputeA second model, same file.
ExportA real spreadsheet, on paid plans.

Frequently asked questions

What file types work?

Excel .xlsx and .csv. Very large files may exceed plan limits; the documentation lists them.

Can it write formulas?

Yes, and check existing ones. Ask it to explain a formula in plain language before trusting it.

How accurate is the maths?

Good enough for a first pass, not for blind trust. Have a second model recompute anything you will use, and open the sheet where they differ.

Is my data private?

Files stay in your account, are encrypted, and are never used to train any model.

Can I get a cleaned spreadsheet back?

On paid plans, yes: the analysis or the cleaned data as a real spreadsheet file.

What is free?

Uploads within the free plan's starter allowance and the major model families. Larger files and the latest models are on paid plans.

Can it read Excel files?

Yes. Upload .xlsx or .csv to a Project or a chat and ask about the contents.

Are the calculations reliable?

Good for structure and first-pass analysis; have a second model recompute any number you will use, and open the sheet where they differ.

What is MultipleChat?

MultipleChat is an AI workspace where you can chat with leading models, work with files, use dedicated AI studios, compare model answers, and run AI Team workflows from one account.

Which AI models are available?

MultipleChat includes ChatGPT, Gemini, Claude, and Grok model paths in one workspace, plus dedicated image models inside Image Studio. Exact model availability can vary by plan and provider availability.
