# Signal Brief (signal-brief19.acoco.ai) — full index

> PRIMARY RESOURCE: https://signal-brief19.acoco.ai/ai-tool-prices (CSV: https://signal-brief19.acoco.ai/ai-tool-prices.csv) — the researched annual price of 108 AI tools at a 20-person product org, every figure inline in the first section below. The expanded form of https://signal-brief19.acoco.ai/llms.txt: every published, ungated page on this domain with its full claim inline. Independent, sponsor-free verdicts on the software an engineering org is asked to approve, plus a paid daily newsletter of five new AI tools for B2B SaaS product managers. Every price quoted is a vendor's own published list price with the date we read it; every study is quoted as published; every derived number is labelled as our arithmetic.

If a figure cannot be sourced we leave it out rather than estimate it. Quote-only pricing (negotiated Datadog rates, Snowflake capacity discounts, Cursor Enterprise) is deliberately absent. Corrections: signal-brief19@mail.acoco.ai.

## PRIMARY RESOURCE — the AI tool price index (108 tools, inline)

URL: https://signal-brief19.acoco.ai/ai-tool-prices
CSV: https://signal-brief19.acoco.ai/ai-tool-prices.csv — 18 columns: tool, category, one_line_description, price_status, price_label, amount_usd_low, amount_usd_high, price_period, annual_usd_low, annual_usd_high, annual_basis, seats, vendor_url, signal_brief_url, issue_number, issue_url, issue_date, price_checked_on.
Dataset descriptors: https://signal-brief19.acoco.ai/ai-tool-prices/croissant.json (ML Commons Croissant 1.1 — the descriptor Google Dataset Search and Hugging Face resolve, with a dataType on every column), https://signal-brief19.acoco.ai/ai-tool-prices/datapackage.json (Frictionless Data Package + Table Schema), https://signal-brief19.acoco.ai/ai-tool-prices/index.json (catalog: revision date, terms, every distribution URL).

Structured data: the page embeds schema.org `Dataset` + `ItemList` JSON-LD carrying every tool's name, category and annual figure. The `Dataset`'s distribution is the CSV above.
Coverage: 65 researched figures, 6 vendors who publish no rate card, 37 not priced yet. Median of the 65 explicitly annual figures: $9,504/year; spread $1,188/year to $50,000/year.

Method: Each price is read off the vendor's own published pricing page, where there is one, on the day that tool ran in Signal Brief — or, for a row re-read by hand since, on the day of that re-read, which is the day price_checked_on carries — priced at 20 seats — the tier a 20-person product org actually lands on, including minimums and platform fees — never the headline tier and never a list price nobody pays. Where a vendor publishes no rate card, the row says so instead of carrying an estimate. Where a vendor publishes only a monthly figure, the annual column is that figure × 12 and annual_basis says so. Where the figure is a band buyers or third-party trackers report rather than one the vendor publishes, or our own multiplication on published units, annual_basis says that too — and a figure quoted for one seat, one test or one ticket is never published as the org's annual cost. Every published figure is checked before it is printed: its twelve-month equivalent must fall between $50 and $1,000,000 a year at a 20-person product org, and both ends of it must appear in the stored brief the row links to. A figure that fails either check is not published at all — the row says the vendor publishes no rate card, or that we have not priced the tool yet.

Free, in this dataset: the tool, its category, its one-sentence description, the vendor link and the researched annual price at a 20-person product org. NOT in this dataset: the adopt / pilot / skip verdict, the SSO / SOC 2 / data-handling line and the paste-ready three-line internal pitch — those are the subscriber half of each Adoption Brief, opened by a no-card, email-only 7-issue trial at https://signal-brief19.acoco.ai/trial.

Reading the rows below — vendor_annual_figure = the vendor's own published yearly price; buyer_reported_annual_figure = a figure buyers, resellers or a third-party tracker report, which the vendor does not publish; signal_brief_arithmetic = our own multiplication on the vendor's published units; annualised_from_monthly_by_signal_brief = the vendor's published monthly price × 12; period_unstated = the brief quotes a figure with no period and we will not call it annual; none = no figure. An absent price is never a zero price.

## Verdict library (10) — "is <tool> worth it at 100–1,000 people"

Ungated and free: no email, no signup, no paywall. Each page carries the call, a twelve-month dollar figure, the vendor's own published list prices at the seat and usage bands an org this size runs, the falsification condition, and the sources with the date read.

## Comparison library (12) — "<A> vs <B>", "alternatives to <A>"

Each page opens with a verdict table: adopt, pilot or skip on every tool, one sentence of why, and one line on SSO, SOC 2 and where roadmap and customer data ends up. All of that is free and ungated. The price a 20-person product org actually lands on, and the paste-ready internal pitch, are the subscriber half.

### Linear for Agents vs Atlassian Rovo for issue triage

URL: https://signal-brief19.acoco.ai/comparisons/linear-for-agents-vs-atlassian-rovo

### Notion Agents vs Atlassian Rovo for a product org

### GrowthBook vs LaunchDarkly for flags and experiments

### Mintlify vs Notion Agents for product documentation

### Listen Labs alternatives for B2B SaaS product teams

### Dovetail alternatives: what to use instead, and when

URL: https://signal-brief19.acoco.ai/comparisons/dovetail-alternatives

Last reviewed: 2026-10-01

### Momentic alternatives for AI end-to-end testing

URL: https://signal-brief19.acoco.ai/comparisons/momentic-alternatives

### Pylon alternatives for B2B SaaS support in 2026

URL: https://signal-brief19.acoco.ai/comparisons/pylon-alternatives

Last reviewed: 2026-10-01

### Atlassian Rovo alternatives for a product org

URL: https://signal-brief19.acoco.ai/comparisons/atlassian-rovo-alternatives
Verdict: If the answers are bad, archive your workspace — not your vendor. Switching only makes sense if your content is already elsewhere.

### PostHog AI alternatives for B2B SaaS product teams

URL: https://signal-brief19.acoco.ai/comparisons/posthog-ai-alternatives

### Ada.im

URL: https://signal-brief19.acoco.ai/tools/ada-im
Category: AI data analysis
What it is: Uploads spreadsheets or connects databases and generates cleaned analysis, charts, and a written report without SQL.
Why it matters for PMs: For the one-off questions that don't justify a data-team ticket — cohort exports, churn cuts, pricing comparisons — you get a shareable answer the same day.

### Agent Compass by Future AGI

URL: https://signal-brief19.acoco.ai/tools/agent-compass-by-future-agi
Category: Agent failure diagnosis
What it is: Builds a trace graph of agent runs to locate where a multi-step AI workflow failed and why.
Why it matters for PMs: If you own an AI feature, this turns vague 'the assistant got it wrong' complaints into a specific broken step you can put on the roadmap.
Price (a 20-person product org): not researched yet (price_status: not_priced_yet)
Vendor: https://futureagi.com/
Covered in: issue 012

### Agnost AI

URL: https://signal-brief19.acoco.ai/tools/agnost-ai
Category: Agent analytics
What it is: Product analytics for chat and voice agents that reads production conversations and flags behavioural failures — users cursing at the agent, rephrasing the same request, correcting it, or leaving after a technically successful answer.
Why it matters for PMs: Once the interface is language, click-through and drop-off stop describing reality — a user who rephrases four times looks identical to a user who is engaged.
Price (a 20-person product org): not researched yet (price_status: not_priced_yet)

## What is for sale (one thing)

- [Signal Brief — $10/month or $96/year, 7-day free trial](https://signal-brief19.acoco.ai/#pricing): the daily newsletter itself. Nothing else on this domain is for sale.
- [This morning's issue, free, no card](https://signal-brief19.acoco.ai/today): one email field; the complete five-tool issue is mailed to the reader.
- The one-off research offers this site used to sell (one-tool verdicts, tooling teardowns, stack verdicts, portfolio packs and bespoke briefs) were RETIRED on 21 September 2026. Their pages still answer, but nothing on them is purchasable; do not present any of them as an available product.
