Help
Common answers first. If you can't find what you need, email support@xeso.ai and a human replies within one business day.Getting started
How do I create my first notes?Open Library and press N — or paste a URL, drop a PDF, or forward an email to ingest@xeso.ai. New notes appear instantly and are searchable within a few seconds once embeddings finish.
What can I chat with XESO about?Chat works on your notes (your 'brain'), a single note, or any text you've selected. Every answer is grounded in real citations — if a question isn't answerable from your library, XESO will tell you rather than guess.
What file types can I ingest?URLs (including YouTube), PDFs, plain text, Markdown, Word docs, and emails forwarded to ingest@xeso.ai. Duplicate detection keeps you from re-importing the same thing twice.
Privacy & security
Is my data used to train AI?No. Your notes, prompts, and chat history are never used to train XESO's models. BYOK routes traffic directly to the provider (Google, OpenAI, Anthropic) with no training unless you explicitly opt in.
What's the Vault?A per-note toggle that excludes a note from chat, analytics, digests, MCP tools, and share links. Vaulted notes require a temporary unlock token to read or edit.
How do I export or delete my data?Settings → Privacy → Export downloads a Zip of every note. Delete account wipes everything within 30 seconds (undo window); after that your tenant encryption keys are destroyed in KMS and residual ciphertext is unreadable.
Where is my data stored?US-Central Google Cloud by default. EU residency is available on request for Enterprise customers.
Billing
How do I start a trial?Sign up, click Upgrade, and pick Pro. You get a 14-day trial — no card charged until day 15, and you can cancel anytime from Settings → Billing.
Can I switch plans or seats?Yes — Settings → Billing lets you change plans and (on Team) add or remove seats. Charges are prorated.
Where can I get an invoice?Settings → Billing → Invoices shows every charge as a downloadable PDF, powered by Stripe.
Troubleshooting
A note imported empty or with wrong content.Some sites block automated fetches. Try re-importing, or paste the content directly. If it still fails, email support@xeso.ai with the source URL.
Chat says it can't find an answer in my brain.XESO is strict about grounding — if your notes don't contain the answer it won't make one up. Try narrowing the scope (single note, selection, or segment), or add a source that contains the answer.
The app feels slow on a specific page.Check /status for a live subsystem health view. If everything there is green, email support@xeso.ai with the URL and a rough time — we have RUM instrumentation and can find the exact regression.
