Everything Tack does
Built for the way solo designers and small studios actually work with clients — one link out, pinned feedback in, certified sign-off at the end.
The review link
One URL is the whole client experience. They open it in any browser — phone or desktop — type their name once, and start pointing at things.
No account, no install
Clients never create a login or download anything. The link is the product.
Point or drag
Click for a numbered pin, or click-hold-drag to mark a whole region with a comment.
Works on phones
Clients review from the sofa. Pins, threads and approvals all work on mobile.
Password & expiry
Protect a link with a password (checked in the database, not just the page), set an expiry date, or revoke and regenerate instantly.
Require verified sign-in
For sensitive projects, flip one switch and reviewers must verify who they are before commenting.
Every format you deliver
Different deliverables, same review surface. Your client learns Tack once and reviews everything with it.
Live websites
Tack captures a full-page snapshot of any URL — clients pin comments straight onto it. Re-sync whenever you publish changes.
Images & social sets
Logos, posts, stories, ads, app screens — upload a set and every image is pinnable.
PDFs & slide decks
Every page becomes a pinnable image. Perfect for brand books and pitch decks.
Video & audio
Comments land at exact timestamps. “Cut at 0:32” finally means 0:32.
Email templates
Upload the HTML — clients comment on the rendered email.
A/B decisions
Show two directions. The client must pick one and say why — the decision is logged like a sign-off.
Feedback that resolves itself
Comments aren't a chat — they're a worklist. Every pin has a status, a thread and an owner.
Threads both ways
Reply to clients from your dashboard; they answer from the link. Everything stays attached to the pin.
Statuses
Open → In progress → Resolved. Bulk-resolve a round when you ship the fixes.
Inbox
Every comment, reply, vote and approval lands in your notification inbox the moment it happens.
Client dashboard
Clients who create a (free, optional) account see every project they've reviewed — across all their designers — in one place.
Certified sign-off
The reason Tack exists: approval as a verifiable record, not a vibe. Read the deep-dive on the sign-off page.
Typed signature + consent
The client signs with their full name and explicitly consents to the record — transparent, ESIGN/UETA-style.
Frozen evidence
SHA-256 fingerprints of every approved file, a hash of the whole conversation, time, IP and device details.
Signed PDF certificate
A digitally signed (PKCS#7), tamper-evident certificate delivered to both parties.
Public verification
Anyone can check a certificate at /verify — drop the PDF and it's hashed in the browser against the registered fingerprint.
Private by default
Client work is confidential until launch day. Tack treats it that way.
Private storage
Files live in a private bucket. Every preview renders through short-lived signed URLs — a leaked file URL goes stale the same day.
Access controls
Password, expiry, revoke, pause — cut reviewer access at the database level, not just the UI.
Encrypted
HTTPS in transit, AES-256 at rest.
