Feedback & sign-off for designers
Design feedback your clients can actually give.
Share one link. Clients point, click and comment straight on your work — then approve with a certified sign-off that holds up later. No accounts. No installs. No “see attached screenshot”.
Free plan included · clients never pay · set up in two minutes
From “thoughts?” to signed-off in three steps
Tack replaces the email chains, annotated screenshots and WhatsApp voice notes with one link your client already knows how to use.
01
Add your work
A live site, images, a PDF deck, a video cut or an A/B test — every format gets the same review surface.
02
Share one link
Your client opens it in any browser. No account, no install, no “can you resend the login?”
03
Collect pins & sign-off
Feedback lands as numbered pins on the exact pixel. When they're happy, they approve — and it's certified.
Everything a review needs. Nothing a client fears.
Pin-point comments
Clients click for a pin or drag for a region. Every comment is anchored to the exact spot — no more “the thing near the top”.
Every format
Live websites (full-page snapshots), images, PDF & slide decks, video with timestamped comments, email templates, and A/B tests with a required reason.
Threads & statuses
Reply both ways, mark Open → In progress → Resolved, and bulk-resolve when the round is done.
Certified sign-off
Approvals become digitally signed PDF certificates with evidence both sides can verify. Built for “but I never approved that”.
Private by default
Files live in private storage behind short-lived signed URLs. Add a link password, expiry date, or revoke access instantly.
Made for solo designers
One flat price. No per-seat math, no enterprise sales call. Your clients never pay anything.
The Tack difference
“Approved” shouldn't be a matter of memory.
Every approval in Tack is a first-class, certified record: your client signs with their typed name and explicit consent, and Tack freezes the approved files, the whole conversation, the time and the device evidence into a digitally signed PDF certificate — delivered to both of you.
Anyone holding the certificate can verify it's genuine, byte for byte. Scope creep and “that's not what I approved” end here.

Questions, answered
Do my clients need an account?+
No. Reviewers open your link, type their name once, and start commenting. If you want verified identity on a sensitive project, you can require sign-in per link — their choice stays free either way.
What can clients review?+
Live websites (as pixel-perfect full-page snapshots), images and social sets, PDF documents and slide decks, video with timestamped comments, email templates, and two-option A/B tests where a reason is required.
What makes a Tack sign-off different from a thumbs-up emoji?+
When a client approves, they type their name as a signature and consent to the record. Tack freezes the approved files' fingerprints (SHA-256), the full conversation, time, and device evidence into a digitally signed PDF certificate delivered to both parties — and anyone can verify a copy at /verify.
How much does it cost?+
Free for your first project. Solo is $17.99/month flat for unlimited projects and sign-offs. Studio is $45.99/month, includes 3 designers, and adds more at $12/month each plus multiple brand profiles. Clients always review for free.
Can I password-protect a review link?+
Yes — per project you can set a password, an expiry date, require verified sign-in, or revoke and regenerate the link instantly.
Your next review could be this easy.
Create a project, drop in your work, and send the link. Your client will figure out the rest — that's the point.
