ChainMemory gives your AI agents persistent memory that belongs to YOU โ€” not to a single vendor.

Save a memory in ChatGPT, recall it in Claude or Gemini. Available via Chrome extension, MCP server (npm), or REST API. Every memory gets a cryptographic fingerprint and project states are anchored with Merkle proofs, so anyone can independently verify integrity โ€” no trust required.

Memories consolidate into a structured Project Brain (decisions, milestones, risks) instead of a pile of raw notes. Multi-agent native: Claude, Cursor and GPT share one consolidated state. Free tier available.

Practically lets you upload any PDF and get back a list of the practical, actionable advice from it โ€” the specific things you can actually do, not a summary of what the document is about.

Most nonfiction books have 10โ€“15 genuinely useful "do this" moments buried across 300 pages. Practically finds them and pulls them out so you don't have to reread or dig through old highlights.

You can also chat with any uploaded PDF to ask follow-up questions, and build a knowledge base from multiple documents so you can ask questions across all of them at once โ€” useful if you're trying to learn a topic from several sources.

Extracted advice can be exported to PDF or Notion.

Free tier includes 3 uploads per month.

Analysis of Practically PDF

Overall verdict

  • Practically PDF appears to be a niche PDF utility/resource site; without verified independent reviews or extensive user feedback, it seems to offer basic, functional PDF-related tools or downloads that may suit casual or occasional needs but lacks the track record of established, well-known PDF platforms.

Questions & Answers

As answered by people managing ChainMemory and Practically PDF.

Which are the primary technologies used for building your product?

Practically PDF's answer:

React and Vite on the frontend, Node.js and Express on the backend, OpenAI's API for the extraction and chat features, Supabase for the database, and Vercel for hosting.

Who are some of the biggest customers of your product?

Practically PDF's answer:

Practically just launched, so there aren't big-name customers to point to yet. Early users are mostly individual readers and professionals, people working through business and self-help books who want to get more out of what they read.

What makes your product unique?

Practically PDF's answer:

Most AI book tools give you summaries or a condensed version of what a book is about. Practically focuses specifically on extracting actionable advice: the concrete, specific things you can actually do. There's also a Knowledge Base feature that lets you upload multiple books and chat across all of them at once, which is useful when you're trying to learn a topic from several sources rather than one book at a time.

Why should a person choose your product over its competitors?

Practically PDF's answer:

If you want a summary, there are better tools for that. Practically is for people who've already read a book (or don't have time to) and want to know what to do differently. The output isn't "this book argues that habits are important", it's a list of specific techniques, frameworks, and steps pulled directly from the text. The Notion export also means the advice actually lands somewhere in your workflow rather than getting forgotten in another app.

How would you describe the primary audience of your product?

Practically PDF's answer:

People who read nonfiction regularly but feel like they're not getting much out of it. That's a pretty wide group: professionals, students, anyone working through a reading list, but what they have in common is that they're trying to actually apply what they read, not just finish books.

What's the story behind your product?

Practically PDF's answer:

I was reading a lot of nonfiction and noticing that very little of it was changing how I actually behaved. The books were good, but the advice was buried and spread across hundreds of pages of stories and research. I started manually extracting the practical parts into notes, which worked, but it was slow. So I built a tool to do it automatically. What started as a personal workflow became Practically.
