Major Updates: Louis AI V3 — Trace for Flow Builder & Refresh Rate

Explore major updates including Louis v3, execution traces for Flow Builder, and configurable refresh rate.

Updated on October 1, 2026

Louis AI V3 is a major upgrade focused on three things: accuracy, reliable doc discovery, and better control for support teams.
This release introduces a new answer pipeline, stronger reasoning, improved guidance management, full Flow Builder logs, and automatic document refresh to keep your knowledge up to date.

Happy New Year — this is our first big release of 2026, and the best is yet to come.

Louis AI V3

We’ve upgraded Louis AI end-to-end to deliver more accurate answers, better doc discovery, and stronger brand control.

New pipeline process (higher accuracy, fewer hallucinations)

Louis now follows a more robust answer pipeline:

  • Refine the user query

  • Retrieve relevant content

  • Rerank for precision (custom model)

  • Generate the response

  • Validate accuracy + optimize performance

2. Better prompts, better reasoning

We improved the core prompt strategy and reasoning flow so Louis:

  • stays closer to your sources

  • answers more directly

  • handles multi-step questions more reliably

3. Date comprehension (temporal awareness)

Louis now understands today’s date, which improves answers involving:

  • deadlines, renewals, “this week / next week”

  • time-based policies and exceptions

4. Better guidance following (more on-brand, more consistent)

Guidance instructions are applied more reliably across tone, escalation rules, and support policies.

5. Better retrieval with custom reranking (find the right doc, faster)**

We implemented a custom rerank model to ensure Louis consistently surfaces the most relevant document chunks — especially when multiple docs are similar.

New: Guidance management (UI)

You can now manage guidance one by one, with full control:

  • Enable / disable any guidance instantly (no need to delete it)

  • Edit and iterate safely without impacting the rest

  • Keep your setup clean by activating only what matters

Major news: Flow Builder Logs (full traceability)

Logs are finally here — and they’re built for real debugging.

You now get a complete execution trace of your bot:

  • Each step = one log entry (input, AI generation, conditions, API calls, data manipulation, output, etc.)

  • See exactly what happened at every step, in order

  • Inspect the state of every variable at any moment via the Variables tab

  • Debug while building and investigate decisions from real conversations

Where to find them

  • In the Flow Builder, click Test → open the Inspector → Access logs

👍 You can now know which use cased triggered for a specific message !

  • In Conversations, click Trace to understand why the bot answered that way

Note: the current view is intentionally “verbose” to maximize detail. We’ll simplify the display soon, but the traceability is already complete.

Document refresh rate (always up-to-date content)

Each document now has its own refresh rate.
When enabled, Louis will** re-fetch the source automatically** to keep answers aligned with the latest version of your content (help center pages, web pages, etc.).

  • Set refresh per document: Never / Daily / Weekly / Monthly

  • Refresh runs at 3:00 AM (UTC+2)

  • Best for content that changes often (policies, pricing, FAQs)

Minor update: Better FAQ / Q&A parsing in Mayday

We shipped a small but important improvement to Mayday for FAQ-style content (question/answer formats).

Previously, when the question was only in the page title, it could be missed during document retrieval — which reduced match quality.
Now, Mayday duplicates the title into the question field, so the query has the full context and the right documents are found more consistently.

Result: better retrieval on FAQ pages with zero change required on your side.
