PaperTrack
Know exactly who's reading your documents — page by page
Third update on PaperTrack, the document-sharing tool I've been building solo. If you missed the first two:
I built PaperTrack because I was tired of sending documents into a black hole
We still don't know if people come for the analytics or the data-room side — so I bet on the data-room side this week
A few people in the comments on #2 asked some version of the same thing: "okay, but how does this actually compare to DocSend? Or Papermark?"
I'd been putting that post off. A comparison post written by the person who built the tool is inherently a little suspicious — of course I'm going to say mine wins. But dodging it felt worse than just writing the honest version, bias disclosed up front. So here it is.
DocSend is still the name most people say first, and it earned that. Page-by-page dwell time, clean viewer, a decade of investor trust behind it. The problem is what happened in March 2025: Dropbox killed the free tier. Now it's a 14-day trial, then Personal at ~$15/seat/mo (or $10 annually) with a visit cap, or Standard at $65/seat/mo (or $45 annually) if you actually want the full analytics. Five people on Standard and you're past $300/month before watermarking or a data room shows up.
Papermark is the one I'd genuinely tell someone to just go use, no caveat about me building a competitor. Open source, and the free plan is actually generous — unlimited documents and visitors, real page-level analytics from day one, not a taste of a paid feature. If self-hosting or not handing your deck to a vendor's black box matters to you, start there. The tradeoff: some access controls and custom domains are paid-only, and support is community-driven rather than a person on the other end of a chat.
PaperTrack, mine, exists because I wanted two specific things neither of the above gave me by default:
Per-recipient watermarking that's actually per-recipient — each viewer's copy stamped with their own email and timestamp at view time, not one static "CONFIDENTIAL" label everyone gets.
A free tier where the analytics aren't a stripped preview — same page-by-page engine as the paid plans. Free tier just doesn't include seats, watermarking, or a data room. Medium is $19/mo ($15 annual), Large is $49/mo ($39 annual, 5 seats + $9/mo per extra seat).
AI document summaries are opt-in per document, always — nothing gets processed unless I explicitly turn it on for that file. Wasn't a competitive move, just didn't want to build a feature that quietly reads someone's contract by default.
What I won't pretend: I'm the youngest of the three here. Papermark's community and self-hosting story is more mature than mine. DocSend's brand weight with investors is real — if your cap table specifically expects that name in the subject line, being cheaper doesn't fix that.
So, plainly: DocSend if the name matters more to your investors than the price. Papermark if you want a strong free tier and don't mind self-hosting. PaperTrack if what you actually lost when DocSend's free tier disappeared was narrower than either — "tell me when someone opens my deck, show me which page they stopped on, don't charge me per seat to get there."
If you've actually used two or more of these — genuinely want to know where I got something wrong above. That's more useful to me right now than "cool tool."
Quick update on PaperTrack (posted here a couple weeks back about building this because I was tired of documents going into a black hole 👋)
Someone in the comments on that post asked something I couldn't really answer yet: do people come for the analytics, or do they stick around once they discover the data-room/security side? Still too early to say for sure, but while digging into that I ended up going pretty deep on the data-room side of things — and realized there wasn't a great free resource out there for people prepping to raise or run a deal. Mostly paywalled legal sites or thin 300-word listicles.
So instead of just writing more marketing copy, I put together 5 actual guides/templates and made them fully free, no email gate:
→ The Ultimate Due Diligence Checklist — every document category investors ask for, why they ask for it, red flags, timeline by stage. Also comes with a free Excel tracker: https://papertrack.io/blog/due-diligence-checklist/
→ Data Room Folder Structure Template — the exact folder tree + naming convention I'd use today: https://papertrack.io/blog/data-room-folder-structure/
→ Data Room Security Checklist — access control, watermarking, audit logs, what actually matters vs. security theater: https://papertrack.io/blog/data-room-security-checklist/
→ Mutual NDA Template — copy-paste ready: https://papertrack.io/blog/nda-template/
→ Term Sheet Template (annotated) — liquidation preference, vesting, anti-dilution, explained in plain English: https://papertrack.io/blog/term-sheet-template/
Not gonna pretend it's purely altruistic — it's also a decent way to get in front of people who are about to need a data room anyway. But I think they're genuinely useful on their own, gate or no gate.
If anyone here has raised recently or run deal diligence — did I miss anything obvious? Especially curious if the folder structure matches what you actually used, since that one's the most "opinionated" of the five.
-
1Yeah, I can see why you’d bet on the data room side. It feels like a much easier problem for people to immediately understand and pay for. The analytics part is definitely interesting, but I’d probably use it as the “oh, that’s actually useful” layer after people are already using the data room. Curious to see which one ends up pulling more users in.
-

Yeah, matches my gut too — data room is a problem people already know they have, analytics is more of an "oh nice" you discover after. So maybe it's less about which pulls more people in, and more "data room gets them in the door, analytics keeps them around." Will know for sure once more people go through a full deal cycle on here.
-
1Yeah, exactly. I think the full deal cycle will tell you a lot more than the initial signups. Curious to see what you find once there’s enough usage data.

Hey IH 👋
Quick backstory: I've spent the last 7-8 years as a technical product owner/lead, plus years of freelance work before that. Across both, the same annoying thing kept happening — I'd send a proposal, a deck, a contract, and then just... wait. No idea if they opened it, no idea if they even scrolled past the first page. I'd just refresh my inbox like that was going to tell me something.
So I built PaperTrack — a document sharing platform that actually tells you what happens after you hit send.
What it does:
Page-by-page analytics — see which page someone's on, how long they spent, when they're viewing it live
Password protection, expiring links, dynamic watermarking, NDA-gated access for anything sensitive
Full data rooms with folder permissions and audit logs for due diligence / M&A use cases
A few decisions I made on purpose:
🔓 The free plan includes full analytics — not a locked "upgrade to see" screen. DocSend has no free tier at all. Papermark has one but gates the useful stuff.
💸 Flat-rate pricing, not per-seat. Watched too many teams get punished for growing.
🤖 The AI document summary feature is fully opt-in, zero-retention. Given people are sharing NDAs and financials on here, I didn't want to cut corners on that just to ship a flashier feature.
It's early — just launched, bootstrapped, building this solo (for now). Would genuinely love feedback from this crowd, especially if you've ever built or evaluated something in the document-sharing/data-room space.
🔗 papertrack.io — free, no credit card needed to try it.
Happy to answer anything — the tech stack (serverless on Azure, fully custom auth), why I made specific product calls, or just general "does this actually solve a problem you have" feedback.

1This is great. Just fix the bottom 2 links under resources in your footer.

“I’d just refresh my inbox like that was going to tell me something” is too real. I think it's clever that you’re building around that weird anxiety gap after someone hits send and then has no signal at all.
I keep coming back to the same thing: people struggle when there’s no feedback loop. The privacy piece is interesting too. For sensitive docs, there’s a balance between giving the sender useful clarity and making sure the recipient doesn’t feel like they’re being creepily monitored.
-

That balance is something I think about a lot, honestly. Right now it's page/duration level, not "they're on this exact pixel for this many seconds" — trying to keep it useful without it feeling like surveillance. Where that line sits is probably the thing I'll keep adjusting as real usage comes in.
And yeah, the anxiety-after-send thing is such a small, dumb feeling but apparently pretty universal — half the reason I built this in the first place.

The “what happened after I hit send” problem is much clearer than the feature list.
Curious whether early users are mainly coming for the engagement analytics, or for the security/data-room side once they realize it’s there.
-

Good catch, and honestly a fair callout on the feature list — that's on me, tried to cram too much into one post.
Too early to say with real data (just launched), but my honest guess based on the reactions so far: the "hit send and then nothing" pain is what gets people to click, since basically everyone's felt that. The security/data-room stuff feels like it's more of a "oh wait, it also does that" discovery once they're already poking around — not what pulls them in initially, but probably what makes teams with actual sensitive documents (contracts, financials) stick around and upgrade.
If that holds up, it's basically: analytics gets the click, data-room/security gets the retention. But ask me again in a month once I've actually got usage data instead of a hunch.
-
1
That makes sense. The distinction between what gets the initial click and what earns retention should be much clearer once you have real usage data.
-
1
Exactly, that's the plan anyway. Will report back once there's actual signal instead of a guess.
-
1
That makes sense. I’ll be interested to see what the first real usage data says once you have enough signal to separate the two.
-
1
Will do — if you want, I can tag you here once there's enough data to actually say something meaningful instead of guessing. Appreciate you following the thread.

Thanks, I’d appreciate that. I’d also be happy to continue the conversation privately if that’s easier — what’s the best email to reach you on?

The positionning here againts Docsend is flawless. As a solo founder building a B2B SaaS, their per-seat pricing has always felt incredibly restrivtive for growing teams. Offering a true free tier with core analytics while charging flat rates is a stellar alternative. I also heavily respect the zero-data-retention approach for the AI summary feature -- when dealing with NDAs and sensitive financials, privacy is non-negociable. Upvoted, dynamic watermarking is great touch ! Great job and good luck for your Launch !

Really appreciate this, thank you 🙏
The per-seat thing was honestly the main trigger for going flat-rate — watched too many teams quietly resent their document sharing bill as they grew. Glad the zero-retention call landed too; felt like an easy thing to cut corners on to ship faster, but not really negotiable once NDAs and financials are involved, like you said.
Solo building too, so comments like this genuinely help more than they might seem to — good luck with what you're building as well, happy to swap notes anytime.
