AI chat for PDF

AI chat for PDFs that keeps the document in context.

Upload course readings, contracts, or reports and ask questions across the file—switch models when you need summary, extraction, or careful reading, without re-pasting every page. Full workspace access requires a Pro or Lifetime plan.

From this 40-page report: list obligations in section 4 and flag anything that conflicts with section 9.
Gemini 3 Flash

I read the attached PDF and separated contractual obligations from cross-references:

  1. 01Section 4 obligations in plain language
  2. 02Section 9 clauses that narrow or override them
  3. 03Items you should verify with counsel

Documents are the source of truth

Copy-paste workflows break on long PDFs.

When page limits, formatting, or multiple files enter the picture, answers need to stay anchored to what you actually uploaded—not a fragment from chat history.

  1. 01

    Truncated context

    Pasting chunks loses structure, tables, and cross-references between sections.

  2. 02

    Re-upload fatigue

    Starting a new chat for every follow-up question wastes time and drops nuance.

  3. 03

    Wrong reading mode

    Summaries, clause extraction, and numeric tables benefit from different models and depth.

Document workflow

Built for questions against real files.

Keep PDFs attached while you summarize, extract, compare, and follow up.

01

PDF attachments

Upload documents so answers reference the file you provided.

Textbooks, briefs, specs, and reports.

02

Model choice

Pick models suited to long reading, tables, or technical language.

Switch as the task changes.

03

Careful reading

Increase reasoning when clauses, definitions, or proofs must be traced precisely.

For contracts and STEM PDFs.

04

Compare readings

Branch alternative summaries or interpretations from the same document.

Useful for ambiguous sections.

05

Supplement with search

Add current external context when the PDF references fast-moving topics.

On supported models.

06

Math in PDFs

Strict Math and visualization when the document is formula-heavy.

Problem sets and technical papers.

Document loop

Upload, ask, drill down, verify.

Treat the PDF as part of the conversation—not a one-time paste.

  1. 01

    Attach the file

    Upload the PDF and state what you need: summary, extraction, or comparison.

  2. 02

    Choose depth

    Use higher reasoning for dense legal or technical sections.

  3. 03

    Follow up in-thread

    Ask page-specific questions without re-uploading; branch if two readings are plausible.

FAQ

PDF workflow questions

What PDF sizes are supported?

Limits depend on model and plan constraints. Very large files may need to be split or scoped to relevant sections—check in-app attachment guidance.

Can milkyway.chat replace legal review?

No. AI can help you read and organize a document faster; important decisions still need qualified professionals.

Does the PDF stay attached for follow-ups?

Yes, within the same conversation thread, so later questions can reference earlier context.

Can I attach images or other files too?

Supported models accept images and documents beyond PDFs. Use the format that matches your source material.

How much does milkyway.chat cost?

Pro is $14.99 per month and includes all premium models plus voice chat. Lifetime is $149.99 as a one-time payment and lets you bring your own API keys. Visit the pricing page for current plan details.

Can I try the workspace before subscribing?

Yes. You can explore the interactive math visualization example without a subscription. After signing in, you can browse the workspace interface, but sending messages requires an active Pro or Lifetime plan.
