Annote is an AI-powered bug reporting tool that turns vague reports into diagnosed, developer-ready tickets.
Most bug reports arrive as a mystery โ "the checkout button doesn't work." No page, no steps, no context. Someone has to reproduce it from scratch before real work starts. Annote removes that step.
How it works: Click the element that's broken on any site โ production, staging, or localhost. Say what's wrong, either by speaking or typing. Annote writes a structured ticket with a screenshot, the console errors, the network requests, and your actions โ and an AI reads that evidence to flag the likely cause before an engineer opens it.
Every bug in one shared session. Reports don't scatter across recordings, Slack, and email. Every capture lands in a single shared session your whole team works from โ assign an owner, set a priority, comment and mention teammates on the ticket, and resolve it together.
Share a session with one link. Anyone can open it in their browser with no signup and no install, so clients and stakeholders can follow along and comment. Sessions can carry your own logo for client work.
What gets captured: console errors and logs, read by the AI for the likely cause. Network requests, status codes, and bodies, with every request copyable as cURL. A full user-action timeline, in plain English for PMs or element-level detail for engineers. A screenshot of the exact element. And voice โ speak the bug, and the AI writes the ticket.
Private by design. Annote captures nothing until you start a session. Secrets and common PII โ tokens, emails, card numbers, API keys, auth and cookie headers โ are redacted in your browser before anything is stored or sent. It never reads what users type, runs on four browser permissions, and uses no third-party analytics.
Who it's for: dev shops, agencies, and product teams โ developers, PMs, and QA โ who want bug reports that arrive complete and get fixed together.
Free to start. No credit card required.
ThreadMine is a Java thread dump analyzer with AI โ detects deadlocks, CPU spikes, pool exhaustion and virtual thread pinning. Free online, no signup.

Annote doesn't just capture a bug - it diagnoses it and gives your team one place to fix it.
Click the broken element, say what's wrong in plain words, and Annote writes a structured ticket with the screenshot, console errors, network requests, and your actions attached. An AI reads that evidence and flags the likely cause, citing what it found, before an engineer opens the ticket.
Then every report lands in one shared session your whole team works from - assign an owner, set a priority, comment on the ticket, resolve it together. Instead of scattered recordings and links, you get one collaborative workspace where the bug actually gets fixed.
Annote's answer
Most bug tools have solved capture - screenshots, console logs, network requests are table stakes now. Annote is built for what happens next.
Two things set it apart:
The AI actually diagnoses. It reads the console, network, and user actions on one timeline and tells you the likely cause with cited evidence - so your team starts from a diagnosed ticket, not a blank one.
Bugs live in one shared session, not scattered links. Every report lands in a single collaborative workspace where the team assigns, prioritizes, discusses, and resolves together. No chasing feedback across recordings, Slack, and email.
Plus: sensitive data is redacted in the browser before anything is sent, sessions open by one link with no signup for viewers, and there's a free tier.
Annote's answer
Development shops, software agencies, and in-house product teams - anyone shipping web software where the person who finds a bug isn't always the person who fixes it.
That means developers, PMs, QA testers, and designers working together. Annote is especially strong for agencies and dev shops maintaining client applications, where vague client-reported issues arrive constantly and someone has to reconstruct them before real work can start.
Annote's answer
I run a web studio, and the same thing kept happening: a client or teammate would report a bug - "the checkout button doesn't work" - and before anyone could fix it, someone had to become a detective. Which page? What browser? What did they click? That reconstruction happened on every single bug, and it was pure overhead.
The context that would have made the report useful - the console errors, the failing network request, the steps taken - was right there in the browser at the moment it broke. It just wasn't being captured.
So I built Annote to capture it automatically, let an AI read it, and put every report in one place a team could actually work from.
