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 document
  2. Ask for review or extraction
  3. Rewrite or create a new output

What opens after login

Document upload, chat, review, rewriting, summaries, action extraction, and continuation into Document or Presentation Studio.

The useful part is not merely reading the file; it is turning it into the next useful artifact.

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.

Ask Multiple AI Models Ask multiple AI models the same prompt in MultipleChat and compare ChatGPT, Gemini, Claude, and Grok answers. Side-by-Side AI Comparison Compare AI answers side by side in MultipleChat to spot disagreements, better phrasing, and stronger reasoning. AI Research Assistant An AI research assistant that cites its sources and gets checked by a second model. Market, competitor, academic and product research in one Project. AI Projects Create an AI Project: files, instructions, code and chats in one place, used as context by ChatGPT, Claude, Gemini, Grok and Perplexity. Free to start. GitHub Code Review with AI Import selected files from a GitHub repository into a Project and have ChatGPT, Claude and Gemini review them. Bugs, security, edge cases, with a model that did not write the code. AI Code Reviewer Paste a file or a diff and get a code review for bugs, security and edge cases, ordered by severity, from ChatGPT, Claude or Gemini. Then a second opinion from another model. AI Fact Checker Check a claim, a paragraph or an AI answer against sources with an independent verification pass, then a second model's reading. Built for the confident-but-wrong problem. AI Second Opinion Get a second opinion from a different AI on the same question and context. Where ChatGPT, Claude and Gemini disagree is where the answer needs checking.
