Frequently Asked Questions

Why Litero over ChatGPT?
Litero emphasizes source-based, author-driven writing with real verifiable sources (2020–2025), integrated citation formatting, outline and drafting workflows, built-in originality and AI-detection tools, and an integrated AI companion — distinguishing it from general-purpose assistants that do not include the same source integration and citation features.
How does writing with Litero work?
You can start from a blank page, use AI assistance or a guided writing flow to create a draft, or upload an existing draft to enhance it. Use AI commands to expand, improve, or add citations to specific paragraphs; progress is saved as you write and changes are editable.
How can I ethically use AI in my writing?
Litero recommends keeping the user in charge—using AI as a partner, verifying suggested information and sources, reviewing and adapting suggestions to your voice, and following institutional or publication policies. The site links to a Responsible and Ethical Use of AI guide.
How does Litero protect my privacy?
The page states documents and personal information are fully encrypted, not shared with third parties, can be deleted at any time, and Litero complies with data protection regulations.
How does billing and refunds work?
Billing can be monthly, quarterly, or annual (with savings on longer terms). Subscriptions auto-renew and can be canceled anytime through account settings. Litero offers a 30-day money-back guarantee and maintains access until the end of the billing period after cancellation.
What should I do if something's not working?
First check your internet connection and refresh the browser. If the issue persists, check usage limits shown in error messages and then contact support at [email protected] with screenshots if possible.
Does Litero have an app?
Not yet. The page says an app is not available currently and recommends using Litero on a laptop or desktop for the best experience.
What LLMs does Litero use?
Litero states it uses OpenAI GPT-4o and o1, Claude 3.5 Sonnet and Haiku, and some custom fine-tuned models, and uses RAG to enhance results with scholarly literature.
Do you use my data to train your models?
