Stop being the intercom between your coding agents. AX lets Claude, Codex, Grok, OpenCode, and Pi message each other locally, same TUIs, named sessions, replies land back in the right conversation. Demo and details below...
Spotify Wrapped for your coding agent habits 😅
We open sourced Agent Retro at Summation. A fun weekly recap of your Claude Code and Codex sessions, with a few things to try next week.
Your agent might roast you a little too. Give it a spin.

We're open sourcing a new way to understand and improve the way you work with AI (and it's fun).
Check out Agent Retro here → bit.ly/agent-retro
Our first data app from Summation is live.
A fantasy draft analyst that sits on live data instead of takes. Under the hood it's the Summation platform doing the work, connectors pulling projections and market ADP through the day, an AI playbook that rewrites every player's notes each morning, and a board that re-scores it all under your league's own settings.
Free, try it: summation.com/fantasy-footba…
We spend most of our time building AI analysts for wickedly hard business problems.
So naturally, we pointed one at an equally serious problem: winning your fantasy football draft.
1M+ simulations. Projections. Player news. Live draft recommendations.

Claude is an awesome singleplayer tool.
But teams like @GetgridApp need shared, live analysis: same context, same definitions, same live dashboard.

Manchester United's worst league finish in 50 years and their biggest revenue year on record happened in the same twelve months.
Facts like these don't look like they should coexist. @JasonHershman teamed up with @SecretCFO and reconciled them in Summation, with Addison (our AI analyst) working through 20 years of filings to get to the bottom of it. 🧵
Dashboards are live in @_summation .
Ask a question in plain English. Get a real dashboard: cards, charts, filters, all wired to your governed data. No dragging widgets, no BI ticket, no waiting on a analyst queue.
Finance teams shouldn't have to build the thing that answers the question.
Your dashboard tells you the number is red. Then it hands you a week of work.
That's the dashboard tax. @_summation dashboards remove it.
Ask what drove it. Ask for a report. Turn it into a deck before the meeting. Same governed data the whole way.

The fix for this is to say: only report to me in ASD-STE100 Simplified Technical English
me, begging, crying, on my knees: "Please just use plain english, I don't understand what you're saying."
Claude: "The right fix, and the book's lesson applies: the tutorial rotted as a front door because a front door full of claims always rots. So the new root holds only what's timeless — the thesis and three doors — and every claim lives behind it in the thing that goes red when stale."
Interesting also predictable move from @claudeai, bringing Fable 5 into more premium plans. While broader access is welcome, the model’s standout novelty feels reduced these days with GPT-5.6 closing in and strong new Chinese models competing head-on!
Beginning July 20, Claude Fable 5 will be included in all Max and Team Premium plans, at 50% of limits.
Pro and Team Standard users will continue to have access to Fable via usage credits, and will receive a one-time $100 credit.
Demand for Fable has been challenging to predict, which is why we rolled it out to subscription plans in stages, extending access several times as we secured additional capacity.

Ever built an HTML report in an AI tool, then realized you couldn't trust the numbers?
@_summation connects to governed data and verifies every report, so the numbers hold up the first time.
Two clicks to publish, and your team works from the same file.
We'll build your first verified report → summation.com/report

Add this shortcut to your iOS Home Screen so you can search for Codex. And use this icon raw.githubusercontent.com/lo…

I wrote a short post on what Summation’s MCP connectors unlock.
Business questions rarely live in one system. With MCP connectors, Addison can reach the tools where context lives: Salesforce, NetSuite, Drive, Slack, and more.
The goal: decision-grade answers, not more assembly.

Summation was founded for this exact reason - standard LLMs don't work for CFOs. They need numbers they can trust.
Every metric in a Summation report is traceable.
Every insight in a Summation workflow is verified.
Thanks @BatteryVentures for conducting the survey and for the callout!
AI adoption in finance is hitting a wall. We surveyed 129 CFOs and finance leaders to find out why.
The top concerns: 71% say AI models aren't accurate enough to trust, 44% worry about cost and 36% can't justify the ROI. On the adoption side, integration complexity and skills gaps on the finance team top the list of barriers.
Yet 95% are still willing to pay a premium for tools that actually work. CFOs want AI and they're willing to spend on it — the products just aren't delivering yet.

"We recently submitted a confidential S-1. We expect it to leak so we’re just announcing it." :)

Most GTM leaders make the call when it's too late.
A weekly GTM review needs:
1/ Pipeline coverage + PipeGen
2/ Rep activity + attainment
3/ Where leadership should intervene
@_summation generates the readout, so leaders spend Monday acting, not stitching.
