Turn messy client feedback into clear product tasks.
From "it's broken" → page, element & console error.From "which button?" → exact selected element.From "nothing happens" → console error, repro steps and task draft.
TellBack captures voice notes, screenshots, selected elements, clicks, browser details, and safe error context — then drafts the dev-ready task and coding-agent prompt.
Pay button throws ReferenceError on /checkout
Pricing CTA may not be discoverable on /pricing
Reposition & restyle the hero CTA
Close the loop between "it's broken" and "it's fixed."
Every messy report becomes a clean, contextual task — so you spend time shipping, not interrogating.
No more detective work
URL, element selector, browser, and console trace arrive attached. Stop asking "which browser were you on?"
Paste straight into your agent
Each task ships a markdown prompt with selectors, evidence, and acceptance criteria for Cursor, Claude Code, or Windsurf.
Clients review in the real app
Send one review link instead of chasing Looms. They click-to-comment in context; you close the project sooner.
Sound familiar? A client sends a voice note, a screenshot with no context, and "it's broken." You spend the next hour asking which browser, which page, which button.
There's a better way — and it takes one script to set up.
The status quo vs. Tellback.
Same feedback. One path costs you a day. The other costs you a paste.
- Feedback scattered across five apps
- "Make it blue" with no page or element
- No browser, viewport, or console trace
- You hand-write the spec before any fix
- Silent, confused users just churn
- One contextual inbox for every report
- Exact element, page, and stable selector
- Browser, viewport & console auto-attached
- AI writes the first task draft for you
- Rage/dead clicks surface silent struggles
"My client sent the same 'the button's broken' voice note I always get — but this time Tellback handed me the exact selector and the console error. I pasted the prompt into Cursor and the fix shipped before I finished my coffee."
Live in ~2 minutes.
One async script for any Next.js, React, or static app. Non-blocking, style-isolated, and safe if our backend ever hiccups.
Paste one script tag
Add the lightweight widget with your public site key. Gated by allowed-origin rules.
Flip on Feedback Mode or share a review link
The widget appears only when you enable it — or for clients on your private review link.
Feedback lands with full context
Testers highlight elements, type, or record voice. Tellback logs the session and friction signals.
Copy the AI task into your agent
Structured cards land in your Project Inbox. Copy or download the markdown prompt and ship.
<script async src="https://tellback.io/widget.js" data-tellback-site="YOUR_SITE_ID"> </script>
⚠️ Replace YOUR_SITE_ID with the public site key from your dashboard. It's a public key — never a secret — and only accepts traffic from your allowed origins.
Everything the AI needs, captured for you.
Event-first, not video-first — and privacy-safe by default. Passwords, card fields, tokens, and hidden inputs are never recorded.
In-product widget
Lightweight, style-isolated, whitelisted to your domains. "Powered by Tellback" on free.
Screenshot capture
Auto-captures the viewport with the selected element highlighted on submit.
Voice notes → spec
Record, preview, re-record. Transcribed and turned into implementation-ready items.
Element picker
Binds the exact stable selector — data-testid, id, aria, semantic path.
Clickstream timeline
Page views, SPA routes, clicks, scroll depth — the path to the problem.
Rage & dead clicks
Detects friction even when the user never says a word — "Silent Struggle" cards.
Console & network errors
Uncaught exceptions and failed requests bound to the moment they happened.
Privacy-safe by default
Passwords, card numbers, CVCs, tokens, auth headers, cookies & hidden inputs are masked. Skip any subtree with data-tellback-ignore.
Coding-agent prompts
Export markdown for Cursor, Claude Code, Windsurf, or generic — one task or a whole session.
Four feedback modes
Collect nothing, page views only, hidden sessions, or full feedback — per site.

Questions, answered.
What is Tellback? ▾
A feedback-intelligence layer for builders. One lightweight widget captures feedback in context — screenshots, voice, clickstream, console errors — and Vertex AI turns it into clean, structured task cards and coding-agent prompts.
Who is it for? ▾
Solo developers building for clients, indie hackers testing SaaS with early users, and vibe coders shipping quick apps with coding agents.
Do I need to install anything? ▾
No server install. Embed one async script tag and configure your public site key. Testers don't need a Tellback account either.
Does it record full sessions or keystrokes? ▾
It's event-first, not video-first. It tracks meaningful events and friction signals — never password, card, or token values. Raw input contents are masked by default.
Can I control what's collected? ▾
Yes — four per-site Feedback Modes: collect nothing, page views only, hidden session tracking, or full feedback with the widget shown.
Does it generate prompts for coding agents? ▾
Yes. Each task produces a markdown prompt with selectors, evidence, and acceptance criteria — ready for Cursor, Claude Code, Windsurf, or a generic agent.
