Ellipses 2.0 listens to your live call through Otter and puts the right thing in front of you at the right moment: the correction, the number, the better phrasing, the question worth asking. Grounded in your own email, Slack, past meetings and store data.
Runs in your own Claude account, on your own connectors. Installing takes a few minutes.

"Your minimum on the 90-count is 5,000 units."
The briefing has the agreed minimum at 3,000 units. Worth correcting before pricing is discussed.
Our last agreement had the minimum at 3,000, not 5,000. Can we confirm before we go further?

About Ellipses 2.0: Your Co-pilot, Always On
Ellipses 2.0 reads the live transcript every 20 to 45 seconds, compares what was just said against a short briefing you control, and returns at most three cards per pass. Each card is color-coded by what it needs from you, carries the words you could say next, and shows exactly where its substance came from. It assists you; it does not hide from the room.
Install Ellipses in Your Own Claude
Ellipses runs inside Claude, on your account and your connectors. A shared link can't lend you someone else's, so you install your own copy. It takes a few minutes.
Download the app file.One HTML file, about 107 KB. It holds no names, accounts or data.
Start a new chat in Claude and attach the file.Use claude.ai or the desktop app, signed in to the account or organization where you want Ellipses to live.
Paste the install prompt and send it.Claude publishes the file as a private artifact and gives you the link.
Open the link and allow access.The first time, Claude asks whether the page may use Claude and your connectors. Say yes, then tap Demo to try every button on a fictional call.
On a team? Share your copy inside your organization.Give the organization Contributor access. Teammates then use the same copy, each on their own Claude and connectors.
File version 2.1.1, November 13, 2026. To update a copy you already have, attach the new file in a chat, paste the install prompt below and add: "Don't make a new artifact. First declare these capabilities on my existing Ellipses 2.0 artifact, then publish this file to it. Same link."
Install prompt
Publish the attached ellipses-2-app.html as a new artifact titled "Ellipses 2.0". Publish the file exactly as it is. Do not rewrite, restyle or shorten it. Use the latest runtime contract and declare these capabilities:
{"sample":{},"room":{},"downloads":true,"user":{"scopes":["profile"]},"db":{"rules":[{"path":"","read":"view","write":"admin"},{"path":"data/users/{self}","write":"interact"},{"path":"stats","read":"admin","write":"admin"},{"path":"stats/{self}","read":"interact","write":"interact"}]},"mcp":{"servers":[{"server":"Otter.ai","tools":["otter_search","otter_fetch"]},{"server":"Gmail","tools":["search_threads","get_message"]},{"server":"Slack","tools":["slack_search_public_and_private"]},{"server":"Google Calendar","tools":["list_events"]},{"server":"Google Drive","tools":["search_files"]},{"server":"Parallel Search","tools":["web_search"]},{"server":"Shopify","tools":["run-analytics-query"]},{"server":"Amazon Selling Partner","tools":["accounts_getMerchants","call_read_only_tool"]},{"server":"Stay","tools":["query_analytics"]},{"server":"Intuit QuickBooks","tools":["profit_loss_quickbooks_account_text"]}]}}
Declare every connector in that list, including any I have not connected yet. The app marks a missing connector as unavailable. When it is published, give me the link and tell me whether every capability was accepted.
What you need
A Claude account that can publish artifacts and use connectors.
The Otter.ai connector connected in Claude, and Otter's notetaker in your meetings. Without Otter, Ellipses works from text you paste.
Any of these you already use: Gmail, Slack, Google Calendar, Google Drive, Parallel Search, Shopify, QuickBooks, Stay, Amazon Selling Partner. In the app, turn off the source chips for the ones you don't have.
What the app can touch
Every connector tool in the prompt is read-only: search and read email, search Slack, read Otter transcripts, list calendar events, search Drive, search the web, run store and finance reports. The app can't send, post, edit or delete anything.

Six Cards, One Glance
Six tiers, six colors, one question each. Urgent cards pin to the top of the stack. Any tier can be muted for the rest of the call, and any card can be pinned to a section you return to later.
Action chips
Every card carries two to four chips matched to the meeting type. Work calls: Check with data, ELI5, Devil's advocate, Suggested response, Add to follow-up. Personal calls: Look it up, Good follow-up question, Remember this.
Three Modes, Your Quality Dial
Pick how hard Ellipses works. Manual when you'd rather tap. Standard for most calls. Turbo when the stakes are high and the room moves fast. Auto mode pauses on its own after a set time, after five minutes of silence, or ten minutes past the calendar event's end, so a forgotten tab never runs up your usage.
Otter's transcript lags speech by up to about ten seconds, so polling faster than 20 seconds adds cost, not speed. Use SOS or the paste box when you need this exact moment.
Manual
No automatic pulls. Tap Check now whenever you want a pass.
Standard, every 45s
Balanced triage on each pass. The right default for most calls.
Turbo, every 20s
Quick-tier triage. An Urgent card with an incorrect verdict auto-escalates to a deep check, capped at three per ten minutes.
Quality: Fast, Balanced, Deep
Sets the model tier for deep checks and answers. If your plan substitutes a tier, the card says which one answered.
SOSOr paste what was just said (Meet captions) and press Enter
Bridge: "Good question. Let me make sure I answer the part about timing first."
Answer: The pilot ships on the 15th if the label proof clears by Friday. The two open risks are the proof itself and the carton count, and both have owners as of this call.
From briefing and transcript
SOS, Brainstorm, Ask
SOS
For when you're called on and lost. One tap pulls the transcript through to now, then returns a natural bridge sentence that buys a moment, followed by a short answer to what was most likely asked. Copy Meet's captions into the paste box, press Enter, and it runs on that text directly.
Brainstorm
One button for the whole call: three to five options the room hasn't considered, each with a one-line trade-off. Keep any of them into your notes.
Ask
Ask anything mid-call. Fast answers from the briefing and transcript, or turn on connectors for a sourced answer in 30 to 90 seconds.
Your Sources, Your Badges
Every output carries a lightweight badge saying where it came from. Any number without a tool or briefing source gets the unverified badge automatically. There is no confidence score to interpret; the badge is the whole story.
Work calls default to as many sources as the plan's tool cap allows, in priority order: Gmail, Otter, Slack, Amazon, Shopify, Google Drive, web search, Stay, QuickBooks. A visible count means nothing is ever dropped silently. Calendar detection and the Otter transcript never take a tool slot. Personal calls use no connectors at all.

Amazon Data, Your Way
Ellipses runs fine without Amazon data. If you sell on Amazon, connect Amazon's official Selling Partner connector in claude.ai under Customize → Connectors, and deep checks can pull your sales and FBA inventory. There's nothing to paste: Ellipses finds your seller account and marketplace by itself, the US marketplace first.
Wired today
Amazon Selling Partner (official)
Amazon's own connector for Claude. Sales, units, orders and average unit price for any date range in the last two years, for the whole store or one ASIN or SKU, plus FBA inventory with inbound and reserved units. Read-only, with no Amazon Ads or traffic data.

Private by Design
No personal data in the page. Your name, time zone, email domain and account IDs live in a per-device Settings panel that starts blank. The page source contains none of it.
Your copy, your account. You install your own copy. It runs on your Claude usage and your connectors, and it doesn't report back to us.
Guest mode. No connectors, no briefing, generic coaching only.
Reset. One tap clears the briefing, findings, pins, notes, transcript, source toggles and settings on this device.
Usage counts stay with you. If you share your copy inside your organization, you can see session and check counts for the people using it. Nothing about what was said is recorded.
Transparent to the room. On personal calls, the other person should know Otter is on the call.
Limits worth knowing
Deep checks use at most four connector calls and cap each result at about 10 KB.
Turbo costs more than Standard; the escalation cap keeps a noisy call from running up usage.
Stay queries are fixed and date-bounded on purpose. QuickBooks answers come from line items only.
Guest mode still uses Otter for the transcript; without it, the paste box is the input.

Find It Useful?
Ellipses is free to install and use. If it saves you on a call and you'd like to buy me a coffee, any of these work. Thanks either way.
