For founders raising, sales sending decks, agencies sending proposals

You sent the link.
Now see exactly what they did with it.

Host any interactive HTML artifact — deck, proposal, audit, board memo — at one clean tracked link. Trail shows you who opened it, which tab they clicked, how long they sat on each section, whether they dragged the calculator, and the moment they hit "book a call". A dead PDF tells you nothing; a Trail link tells you who's a buyer.

Demo · what a Trail replay looks like

You sent the deck.
Here's the replay.

Below is exactly what Trail shows after someone opens your link. Flip between two viewers who got the same deck — and watch one turn into a booked call while the other bounces in eighteen seconds.

Same deck, two viewers. One booked a call. One was gone in 0:18. Your PDF couldn't tell the difference.

◆ This is what a Trail replay looks like. The dead PDF version of this deck would've told you it was "delivered" — nothing more. Trail shows you acme-ventures is ready for the call, and pings you the second they hit it.
Put your next deck behind a tracked link — $19/mo, 10 links, per-viewer timeline. Cancel anytime.

Why bother

Three numbers that decide it.

0:18
The bounce a PDF would've hidden
Email "open" tracking lies — it fires on a preview pane. Trail measures real dwell per section. The cold viewer above never reached your pricing slide; you'd have chased them for a week.
1 link
For the whole living document
No re-upload when you edit a number. The link stays the same; the artifact updates. Every viewer event keeps accruing under one URL — deck, proposal, audit, board memo.
16:02
The minute they became a buyer
The exact timestamp acme-ventures clicked "book a call". Trail pings you the second it happens — you reply while the deck is still open on their screen, not three days later.
How it works

Three moves. One link.

⤳ STEP 01
Drop in your artifact
Upload an HTML deck, proposal, or audit — or paste a URL. Trail hosts it at one clean tracked link: trail.link/your-deck. No build step, no re-export when you change it.
⤳ STEP 02
Send the link, not the file
Email it, DM it, drop it in the thread. Every viewer gets the same URL. Trail watches sections, tab clicks, scroll depth, calculator drags, and CTA hits — per viewer, per visit.
⤳ STEP 03
Read the replay, work the heat
Per-viewer timeline + a lead-heat score. Email or Slack alert the moment someone goes hot. You follow up the buyers and ignore the skimmers — instead of blasting everyone.

FAQ

The honest answers.

How is this different from DocSend?

DocSend is built for static PDFs — it tells you a page was viewed for N seconds. Trail is built for living, interactive HTML: it captures tab clicks, calculator drags, accordion opens, and CTA hits, and the link never changes when you edit the document. If you send dead PDFs, use DocSend. If you send the kind of interactive artifact the html-first playbook describes, use Trail.

What's the refund policy?

14-day full refund, no questions. Reply to vlad@belkins.io. Cancel anytime via Stripe — Solo and Team both.

Do my viewers have to sign in or install anything?

No. Recipients just open the link in a browser. Trail identifies viewers by email if they opened it from a tracked send, otherwise by a privacy-respecting session — no app, no login wall in front of your deck.

Can I track an artifact I host myself?

Yes — paste a URL and Trail proxies it at your tracked link, or drop in a snippet for full self-host. Either way the timeline and lead-heat scoring work the same. Self-host details land with the first paid cohort.

Is the lead-heat score real or made up?

It's a weighted blend of real signals — section dwell, return visits, calculator/CTA interaction, and time-to-pricing. The demo above uses canned data so you can see the contrast, but the scoring logic is exactly what runs in product. We show you the inputs, not a black box.
