Rezonant - Talk, spec, ship: get your product ideas into production
Rezonant helps product teams turn messy ideas into code-ready specs, tickets, and engineering tasks. Collaborate with PMs, engineers, designers, and AI agents in one shared workspace. Ground decisions in your actual codebase, keep everyone aligned on the same version, and create work that humans and coding agents can confidently ship.

👋 Hello Product Hunt!
Now that anyone can ship code quickly, the bottleneck has moved upstream, to the question of what gets built and why.
Rezonant sits above tools like Cursor, Claude Code and GitHub Copilot. It gives product managers a live, multiplayer workspace to turn product ideas into structured specs and tasks that AI coding agents can actually execute - grounded in the codebase, not floating around in Notion docs and Slack threads.
Capture ideas with our Chrome extension, Rezonant Alter. Hit record, point to anything on your live product, prototypes or designs, and talk through your thinking out loud, just like you would with a dev or designer. Alter captures what you said and what you pointed to, maps it to your codebase, and surfaces it as a spec or PRD ready to edit, comment on, break into tasks, and ship.

Can’t wait to see what you build!

@emma_burrows Congrats on the launch Emma. What's the usp over something like slack here?
Rezonant
hey @zolani_matebese -- thanks for the question!
I'd say the focus is very different. Slack is meant to facilitate conversations between team members, customers, or agents.
Rezonant is meant to generate output (like markdown specs or JIRA/Linear tickets) that can be picked up by coding agents.
the ambition is for rezonant to be the best place where team can drop a feature idea (through the UI or chrome extension) and that quickly kicks off the delivery process, with a spec being generated and a coding agent picking the up the task.
Hope that clarifies?
@emma_burrows "The bottleneck moved upstream to what gets built and why" is the right read, shipping code stopped being the hard part the moment agents got good at it. Grounding specs in the actual codebase instead of a Notion doc is the real unlock here. The question that follows: a spec is a snapshot, but the codebase keeps moving. PM writes it Monday, three PRs land by Wednesday, and now the agent executes against a repo that no longer matches the spec it was handed. Does Rezonant re-ground a spec against the current code at execution time, or flag when the ground truth it was written on has drifted? For "humans and agents can confidently ship," that confidence lives entirely in whether the spec still describes the codebase it claims to. Stale spec, confident agent, wrong build is the failure mode I'd worry about most.
Hey @arturbrugeman - great questions. You currently can chat to Rezonant and say something like "update this spec with the current codebase" and it'll get everything back up to speed. It's on our roadmap to build this out further - updating automatically and flagging when anything's changed.
@emma_burrows Congrats on the launch. Quick question on Alter. When a PM points at a UI element and says "this button", how does Alter map that back to the right component in the repo? Especially curious about codebases with hashed class names (Tailwind JIT, CSS modules).
Rezonant
@whetlan hey there! Thanks :)
Alter actually works really well with Tailwind, CSS Modules, and other hashed-classname setups — when a PM points at an element, the agent locates the relevant components in the Github repo!

@emma_burrows This is a solid observation about where the real constraint lives now. The workflow you're describing—capturing context from live products and turning that into executable specs—directly addresses a pain point teams face when async communication breaks down. The Chrome extension angle for capturing intent is clever since product thinking often happens outside your tooling.

@emma_burrows @osakasaul thanks for the support, saul!
@emma_burrows @vincenzo_bianco2 and team - first of all, congrats on the launch. Looks really impressive! Quick question on the Chrome extension - how does that workflow work in practice? If a PM or engineer submits feedback or feature requests through the extension, how does Rezonant turn that into something Claude Code can execute?
Rezonant
hey @zevi_reinitz -- appreciate the support and thanks for the question! :)
The chrome extension is meant to let you quickly capture feedback on your webapp. For example, you can use the 'record' mode to describe a feature your customers have been asking for.
From then:
- Rezonant elaborates your transcript + interactions with your product to understand your intent
- Rezonant connects to your GitHub and other context (your docs, product roadmap, meeting notes, etc.) to define what it takes to ship that feature: this is the crucial step in which the agent plans implementation while keeping your product context in mind.
- Rezonant will produce a spec and/or a number of tasks to implement that feature
- You can export tasks as Linear / JIRA tickets. Docs can be exported as .md files
- You can ship the feature with a coding agent directly from Rezonant UI or from Claude Code/Codex!
Hope that clarifies the workflow!

Thanks for the support @zevi_reinitz !

@nalin_rajendran appreciate the support nalin! what's your stack to build these days? keen to hear how Rezonant will fit in there!
@nalin_rajendran Thanks Nalin!
Super excited to get this released and to see how teams use it!
@sam_walker13 Love the positioning above Cursor and Claude Code — the upstream bottleneck is real. One question though: how do you handle the "lost in translation" risk? If a PM records a rambling voice note pointing at the UI, and Rezonant interprets the intent into a spec, how does the team catch it if the AI misread what was actually meant? Is there a review step before tasks gget pushed to the coding agent?
Rezonant
@sam_walker13 @haotian_wang5 hey -- yes! we let teams customize how much review they want to go through before shipping.
Specifically, you can review (or ask your team members) to review the specs and tickets generated before sending them coding agents!
How does your team currently handle that?
Loved working on this! 🎉 It's really cool to be able to go back to more natural ways of communicating, bringing products to life just by chatting through ideas and features like you would with the team.
Rezonant
@abi_church LFG!

Very excited to launch Rezonant - check out the agent document editing functionality, really great for drafting and critiquing documents (shout out to @Tiptap AI Agent)
@sam_stephens2 🙌 🎉 🚀

@sam_stephens2 Amazing! Congrats on the launch 🙌
Congrats on the launch. Most broken features I've watched ship were already broken at the PRD stage. The engineering work just compiled the misunderstanding faster. With agents grabbing tickets directly out of Rezonant, what's the QA loop before that handoff?
Rezonant
@artstavenka1 Great question!
There's 2 layers of QA:
The Rezonant agent will flag edge cases and fill the gaps in your feature description while drafting a spec for you.
Rezonant is a collaborative workspace so you can review your PRDs/specs/tickets before 'handing off' to coding agents.
Hope that answers your question? How do you currently do that with your team?
Thanks for the support@artstavenka1! 🫶
Congratulations on the launch team! Fantastic product. We’ve been using it internally for weeks and it has made a significant impact on our engineering productivity. Have shared it with several friends across startups. 💪🏻

@lorcan_delaney thanks for the support and shoutout!!
@lorcan_delaney Thanks Lorcan! Glad you're enjoying using it 😁
Love this! The flow mode to PRD is great. Also enjoying sending straight to coding agents for simple tasks.
Thanks@matt_gunby! So glad to hear you're enjoying it. What're you building?
Tiptap AI Agent
It's a pleasure to work together and see your launch! I wish you lots of success moving forward.

Thanks @arnau_gomez_farell! Looking forward to working more together as we build this out 🙌
@arnau_gomez_farell Thanks Arnau! Appreciate the support
