Get more context
Get better answers from AI
Blaine doesn’t treat a response from AI as one block of text. It reads the claims inside it, tests what can be tested, and shows you what held up, what didn’t, what was revised, and why.
Blaine.chat checks its AI answers, including answers about your uploaded documents, with code, rules and real sources. Every claim gets a mark: Supported, Disputed, Corrected or Unconfirmed. Tap any mark to see why.
Built with a neuro-symbolic reasoning layer
- Blaine CortexChecks its own work before you see it, so every claim arrives marked Supported Disputed Corrected
- Blaine ChameleonBecomes the right expert for whatever you bring up, on every message, even the niche stuff.

How Blaine reviews your work
Blaine reads the claims inside an answer, tests what can be tested, and marks what held, what did not, and what was revised, to stay informed.
A word from the architect:
Just as Autocomplete on your smartphone can sometimes incorrectly predict the next word in a sentence, Large Language Models or “LLM’s” (AI) can also incorrectly predict the answer to your question, or fill in what it doesn’t know with 100% fabricated information (known as “Hallucinations”).
This is an inherent limitation of LLM’s due to how they fundamentally operate (via prediction, rather than true intelligence).
Ergo, as with ALL AI’s, 100% accuracy is NOT possible 100% of the time. Therefore, Blaine checks responses and transparently gives you more context, accuracy, and confidence… Without bleeding away your tokens.

One workspace for reasoning and execution
Blaine brings conversations, documents, code, background agents, connected tools, media, and data control into one workspace. The same reasoning layer follows the work instead of stopping at a prompt-and-answer box.
A mark on every claim
Each mark sits beside the part it belongs to. Supported, Disputed, Corrected, or Unconfirmed — so you can see what to trust before you act.
Documents and files
Create, upload, edit, and download office documents, Markdown, text, and JSON. Bring PDFs, images, and other attachments into the work.
Code and background agents
Use a dedicated Build mode, run Python or JavaScript, inspect code with GitHub context, and hand longer goals to background agents with live logs and stop controls.
Research and connected tools
Fetch pages, search the web, inspect ZIP archives, work with attached files, and generate downloadable images or video when connected providers support it.
Models, personas, and rules
Choose Auto or your own model, connect OpenRouter, Abliteration.ai, Hugging Face, Fireworks, LiteLLM, or your own OpenAI-compatible endpoint, and control behavior with personas and Agent Rules.
Your memory, context, and data stay yours
See transparently what Blaine remembers about you in Settings. Edit or remove individual memories, turn future memory capture off, or clear account memory altogether.

Questions people ask
How can I tell if an AI answer is true?
Look for proof behind each claim. Blaine checks the claims in its own answers with code, rules and real sources, then puts a mark beside each part: Supported, Disputed, Corrected or Unconfirmed. Tap any mark to see why.
What do the marks mean?
Supported means two independent reliable sources agree with the claim. Disputed means a reliable source says something different, or the answer clashes with something said earlier. Corrected means a part was proven wrong, so it was fixed or taken out, and you can tap it to see the original. Unconfirmed means no source settled it.
Which sources does Blaine use?
Reputable sources, such as journals, government and official sites. Forums, social posts and SEO blogs do not count. A claim is only marked Supported when two independent reliable sources agree.
Does AI make things up?
Sometimes. AI can state a wrong fact, number or date with full confidence. That is why Blaine checks each claim in its answer and shows you which parts held up and which did not.
Does Blaine use another AI to check the AI?
The marks come from code and fixed rules that weigh what reliable sources say. Math, dates and unit conversions are worked out exactly by code.
Can I ask about a document or file?
Yes. Attach a PDF, Word file, text file or image and ask about it. Blaine answers and checks the claims in its answer.
Is Blaine free?
You can start free with 30 answers a month. Managed access is $14.99 a month or $149 a year. Work pauses at your limit instead of adding charges.
Is Blaine always right?
No. Blaine is a decision support tool, not a guarantee of accuracy. The marks show you what to trust and what to double check. For important decisions, use your judgment and verify key information.
Do you use my chats to train AI?
No. We do not use your content to train our own models, and we do not send it to any model provider that trains on it.
