Improve Answer Accuracy & Stop Wrong Chatbot Answers

A chatbot that gives a confident wrong answer is worse than one that says "I don't know." Alee is built to avoid that — every answer is grounded only in your own content and self-checked before it sends — but the bot can still get things wrong when a source is missing, outdated, or vaguely worded. This guide shows you how to diagnose exactly why a bad answer happened, fix it at the root, and tune grounding and fallback so the bot stays sharp.

First, understand why Alee answers wrong

Alee uses Advanced RAG. When a visitor asks something, the bot embeds their question, retrieves the closest chunks from your knowledge brain, and an LLM writes an answer grounded only in those chunks — then self-checks that answer for grounding before sending. Because of that design, the bot will not invent facts out of thin air. So a "wrong" answer almost always traces back to one of four causes:

• Missing source. The fact simply isn't in your knowledge brain, so the bot honestly says it doesn't know — or stretches to answer from a loosely related chunk.
• Stale content. The fact is there, but it's an old version: an outdated price still sitting on a crawled page, last season's timings, a discontinued product.
• Vague phrasing. The fact is buried in marketing copy or a long paragraph, so the embedding match is weak and the bot retrieves something less relevant.
• Wording mismatch. The visitor asks in words that don't resemble anything in your content (a different language, slang, an acronym), so retrieval misses.

Almost every accuracy problem you'll meet is one of these four. The trick is to identify which one before you start fixing.

Diagnose the bad answer

Before you change anything, reproduce and classify the problem.

1. Find the real question. Open the bot's analytics and check the Top Questions list and the question-triage inbox. These show you the exact wording visitors used and what the bot replied — far more useful than guessing. The triage inbox lets you mark a question important, FAQ, or answered, so flag the bad one to track it.
2. Reproduce it in the test chat. Open the bot's preview and ask the question in the visitor's exact words, not your cleaned-up version. Many bugs only appear with the messy real-world phrasing.
3. Read what the bot actually said. Decide which category it falls into:

• The bot said "I don't have that information" → missing source (or a wording mismatch).
• The bot gave an answer that used to be true → stale content.
• The bot gave a fuzzy, generic, or half-right answer → vague phrasing in the source.
• The bot answered fine when you reworded it but failed on the original → wording mismatch.

1. Check which source it pulled from. If you can see the cited sources on the answer, trace the chunk back to the page, PDF, or text source it came from. That tells you exactly what to fix.

Once you know the category, the fix is straightforward.

Fix 1: Add the missing source

If the answer simply isn't in the brain, add it. Alee can learn from a website URL, a full sitemap, PDFs and documents, YouTube transcripts, and raw text you paste — and you can add sources any time; the brain grows.

• For a public fact that already lives on a clean page, open the bot's Sources area and crawl that page (or the whole sitemap to grab many pages at once).
• For a fact that lives in a brochure or report, upload the PDF.
• For a fact explained in a video, add the YouTube URL so Alee uses the transcript.
• For a fact that lives nowhere public — internal policy, seasonal pricing, a WhatsApp-only number — paste it as a raw text / FAQ source. This is the most reliable option because you control the exact words.

After adding, wait for the short processing window, then re-ask in the test chat. See add PDF and document sources or the features overview for the full source list.

Fix 2: Refresh stale content

Stale answers are the sneakiest, because the bot sounds confident. The cleanest fix is always to update the source itself.

1. Fix it at the original. If the wrong fact is on a webpage, correct it on your site, then re-crawl that page so the source updates. If it's in a PDF, delete the old file and upload the new one.
2. Add a precise text override as backup. Even after re-crawling, paste a clean Q&A pair stating the correct fact directly (more on overrides below). A focused, specific entry tends to get retrieved ahead of a vague mention.
3. Remove contradictions. If two sources disagree, the bot may retrieve either one. Keep a single source of truth per fact and delete duplicates.
4. Refresh the cache. Repeat or similar questions are served instantly from a cache, so an old answer can linger after you fix the source. Re-ask the corrected question, or use the triage inbox to teach the better answer, to refresh what gets served.

Fix 3: Sharpen vague phrasing with a text override

When the fact exists but is buried in fuzzy copy, the fix is to give the bot a clean, specific version to retrieve. Pasted text is the only source type where you control the exact words, which makes it the most powerful accuracy tool you have.

1. Open the bot's Sources area and add a raw text / paste text source.
2. Name it clearly (Pricing FAQ, Shipping & returns) — visitors never see this.
3. Write the fact as a question-and-answer pair, phrasing the question the way a real visitor types it, then a complete, standalone answer.
4. Save, wait for processing, and re-test.

Good override habits:

• Keep each answer self-contained. Chunks get retrieved in isolation, so don't write "as mentioned above." Repeat the key noun instead of "it" or "they."
• One topic per entry. Smaller, focused entries chunk and retrieve more cleanly than a giant paragraph.
• Put numbers in plain words. Write "₹499 per month," not "see pricing table." The bot answers only from what's in the text.
• Add the phrasings people really use. List variants right in the question line so retrieval matches more queries.

Fix 4: Close the wording-mismatch gap

If the bot answers fine when you reword the question but fails on the visitor's original, retrieval is missing because the wording is too different from your content. This is common for India-facing bots where visitors mix English and Hindi, or type "cost" / "kitne ka hai" / "price" for the same idea.

The fix is to feed those phrasings into a text source. You can stack variants in one question line:

```
Q: What are your timings? When are you open? Office hours? Kab khula rehta hai?
A: We're open Monday to Saturday, 10am to 7pm IST. Closed on Sundays
and national holidays.
```

Now whichever way a visitor asks, the embedding lands close to your answer.

Tune grounding and fallback

Two settings shape how cautious or generous the bot is — and both live in the bot's persona / system prompt, where you set tone and rules.

Grounding is Alee's core guarantee: answers come only from your content, and each one is self-checked before sending. You can reinforce it in the persona. Tell the bot, in plain words, things like:

• "Only answer using the provided knowledge. If the answer isn't there, say you don't know."
• "Never guess prices, dates, or policies. If unsure, ask the visitor to contact support."
• "Keep answers short and quote the specific figure or policy from the source."

A tighter persona makes the bot lean toward "I don't know" rather than stretching — which is exactly what you want when accuracy matters more than coverage.

Fallback is what the bot says when it genuinely has no grounded answer. A good fallback turns a dead end into a next step. Instead of a bare "I don't know," set the persona to offer a path:

• Hand over a contact or booking link.
• Ask for the visitor's name and email so you can follow up — Alee can capture leads right in the chat and push them to your CRM, Google Sheets, or email via webhook.
• Suggest a related question the bot can answer.

The honest "I don't know it" plus a helpful next step beats a confident wrong answer every time.

Worked example: the ₹299 price that won't die

Your old landing page still mentions a launch price of ₹299, but you've moved to ₹499. Visitors ask "what's the monthly price?" and the bot keeps replying ₹299.

1. Diagnose. The triage inbox shows the bot citing the old landing page → stale content.
2. Fix the source. Correct the price on the site and re-crawl that page.
3. Add an override. Paste a Current pricing text source:

```
Q: What is your monthly price? How much does it cost? Price kya hai?
A: Our plan is ₹499 per month, billed monthly. This is the current
price as of June 2026. There are no hidden charges.
```

1. Refresh the cache. Re-ask "what's the price?" in the test chat. If the old answer still shows from cache, re-ask once more or teach the new answer from the triage inbox.
2. Confirm. Ask two phrasing variants to be sure.

The bot now answers ₹499, grounded in a source you fully control.

Build an accuracy habit

Accuracy isn't a one-time fix; it's a loop.

• Watch Top Questions weekly. Every question with a weak answer is a text source waiting to be written.
• Use the triage inbox. Mark questions important, FAQ, or answered, and teach a better answer where the bot fell short.
• Re-crawl after every change. New plan, new shipping zone, festival hours — update the matching source the same day.
• Test like a customer, not the owner. You know the right keywords; your visitors don't. Ask in their messy phrasing.

Frequently asked questions

Why does my Alee bot say "I don't know" when the answer is on my website?

Either the page isn't in the knowledge brain yet, or the visitor's wording is too different from your content for retrieval to match. Crawl the page (or add a text source) and include the real phrasings people use in the question line.

Can Alee give a wrong answer or hallucinate facts?

Alee grounds every answer only in your content and self-checks it before sending, so it won't invent facts. A "wrong" answer is almost always stale or vague source content — fix or override the source and refresh the cache.

How do I force the bot to use a specific answer?

Paste a clean, specifically worded Q&A as a text source, fix or remove any contradicting source, and refresh the cache by re-asking or teaching the answer from the triage inbox. A focused entry usually gets retrieved ahead of a vague mention.
