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. Create the Project, write the instructions
  2. Add files, code and notes
  3. Work with any model from that context

What opens after login

Inside the app a Project holds instructions, files, imported Drive and GitHub content where enabled, and every chat about it. Switch models freely; the context stays.

Paid plans add more Projects, larger uploads, the latest models and shared Projects for teams.

Create a project

Choose the right model path

One Project per thing

The business, the codebase, the client, the research topic. Not one giant Project for everything.

Instructions are the brief

Who, what, conventions, what never to do. Every model reads them before every task.

Files are the evidence

Upload PDFs, spreadsheets, docs, screenshots and code; import selected Drive and GitHub files where enabled.

Compare inside the Project

Ask two models the same question against the same files. Disagreement is the useful output.

Use chat, files, and studios from the same account

01

Chat with files

Upload PDFs, documents, spreadsheets, or images and ask questions about the content.

02

Image Studio

Create image prompts and continue into the dedicated image generation workflow.

03

Document Studio

Generate reports, proposals, resumes, and structured drafts.

04

Presentation Studio

Create decks, outlines, pitch materials, and training presentations.

05

Excel Studio

Work with spreadsheets, formulas, CSV files, and data analysis tasks.

06

Projects

Keep chats and files organized around a client, topic, codebase, or research area.

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.

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.

What goes into a good Project

Instructions: who this is for, what it is, the conventions, what never to do. One page, written once. Files: the documents, spreadsheets, screenshots and code that the work depends on; imports from Google Drive and GitHub where enabled. A decisions file: what was chosen, why, what was rejected, so no model proposes what you already ruled out. Then the conversations, which accumulate.

One Project per thing. The business, the codebase, the client, the research topic. A Project that holds everything holds nothing useful.

InstructionsThe brief every model reads first.
FilesEvidence, uploaded once.
DecisionsSo nothing gets re-argued.
ChatsAll of them, in one place.

Frequently asked questions

What goes in a Project?

Instructions, files (PDF, DOCX, XLSX, images, code), imported Drive and GitHub files where enabled, and all the chats about the subject.

Can several models use the same Project?

Yes. That is the point: ChatGPT, Claude, Gemini, Grok and Perplexity all read the same context, so a second opinion costs one message.

How is this different from ChatGPT's projects?

Model choice. A MultipleChat Project is read by five model families, so you can cross-check inside it rather than trusting one vendor's answer.

Is my Project private?

Yes. Files and conversations stay in your account and are never used to train any model.

Can my team share a Project?

On team plans, yes: shared Projects, chats, prompts and files with seat management.

What is free?

Your first Project, file uploads with a starter allowance, and the major model families. More Projects, larger uploads and the latest models are on paid plans.

What is a Project?

A folder that every AI model in MultipleChat can read: files, instructions, code and the conversations about them.

How many Projects are free?

The free plan includes your first Project with a starter upload allowance. Paid plans include many more.

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.
