Anku is a product diagnostics tool that reads a company's existing PostHog analytics data and turns it into finished work items rather than charts. Its homepage describes the gap it targets: analytics tools show where people leave, and Anku tells you what to fix. Each diagnostic ends in a UX blueprint, a set of targeted user questions, or a code patch.
The product is positioned for teams that already collect events in PostHog and want a faster path from drop-off data to a decision. Anku describes itself as an independent product diagnostics platform and states that it does not store customer personally identifiable information. A free landing page audit is available for visitors who do not use PostHog.
Setup uses a read-only PostHog Personal API Key. The user picks the US or EU region to match their PostHog cloud, then pastes a key with read scope for Events, Persons, and Insights. Anku probes the key with a two-second budget before storing anything. No tracking code is installed and no write access is requested.
Diagnostics can be run on demand, which the integrations page says takes under 60 seconds, or on an optional weekly scan at 09:00 UTC on Mondays. Raw event data is processed in memory and not persisted. Each scan is compared against a baseline, so a new regression can surface on the day it ships.
Anku produces three deliverables. The UX blueprint finds friction in a flow, draws a new one, and writes a spec prompt for an AI builder. The outreach deliverable identifies five users who hit a wall and drafts one blunt Mom Test question for each; the owner sends them. The code patch groups similar crashes and proposes a diff to verify with replay.
The homepage sample report shows the approach on an app called Zoju, where 57 percent of signups never reached the practice test, the product's aha moment. Users who reached it returned at 61 percent, versus 3 percent for those who did not. Anku's suggested fix moved that step forward in the signup flow.
Anku is a product diagnostics tool that reads PostHog analytics data and produces finished deliverables. These include UX blueprints, targeted user outreach drafts, and suggested code patches. It is meant to tell teams what to fix rather than only where users leave.
Anku has a Free plan with no card required and a Pro plan at $49/mo flat, cancelable anytime. Pro includes unlimited on-demand diagnostics, an optional weekly Monday scan, targeted user feedback, and ready-to-ship fixes. Founding members keep the $49 price forever.
Yes. Pro includes a 7-day free trial. The card is entered on Polar at checkout, you can cancel anytime, and you are not charged until the trial ends. A separate free tier offers a landing page audit with no card.
Anku uses a Personal API Key with read scope for Events, Persons, and Insights. It does not need write access or tracking code. It probes the key with a 2-second budget before any persistence.
Anku connects natively to PostHog US and PostHog EU. Segment, Mixpanel, Amplitude, and Snowflake are supported through PostHog ingestion, so their data must be sent to PostHog first.
The company states that zero customer PII is stored. Raw event data is processed in memory and not persisted, PII is scrubbed before synthesis, and the site cites AES-256-GCM encryption.
Partly. The free URL audit lets you audit a landing page without PostHog. The full diagnostics in Pro rely on a connected PostHog account.
You can run a diagnostic on demand whenever you ship, which the site says takes under 60 seconds. An optional weekly scan runs Mondays at 09:00 UTC, and each scan is compared against a baseline.
