Every claim has a source
Each finding links to the excerpt it came from. Citations are re-checked against the stored source text before a report is published; anything that can't be traced is removed or marked unverified.
Coming soon to Windows
Research you can check line by line.
Ask a question. Acastus Intelligence plans the research, finds sources, reads them, checks every fact against the original text and writes a report where every statement links to its source.
When the evidence doesn't settle something, the report says so instead of guessing.

How it works
From a question to a cited answer
- 1
Ask
Type a question, or add what to compare and what matters to you. Pick an effort level from Quick to Max.
- 2
Agents research
Planner, search, reader, fact-checker and writer agents find sources, read them and keep only facts that match the original text.
- 3
Read the answer
A direct answer with a comparison table, tradeoffs and what is still uncertain. Click any citation to see the exact excerpt.
What you get
Built so you don't have to take its word for it
An answer, not a pile of links
Reports open with a direct answer, a side-by-side table, the tradeoffs and what couldn't be verified. A report that only lists evidence is never rated "useful".
Evidence explorer
Browse every claim with its confidence, how many independent sources back it, and conflicts between sources. Open the original page or the stored text.
Comparison studio
Compare products, options or ideas on the criteria you choose, with weights you can change and the source behind every value.
Living Research Pro
Keep a topic up to date: scheduled re-checks find what changed and tell you, with a new report version you can compare to the last one.
Export anything
Save reports as PDF, HTML or Markdown, and the evidence as CSV or JSON, with citations intact.
Effort levels
As quick or as deep as you need
Every plan has every effort level.
Quick minutes
A fast answer from a handful of strong sources.
Standard default
A balanced report for most questions.
High deeper
More sources, more cross-checking, more detail.
Max deepest
The most thorough research, for decisions that matter.

Usage is a rolling 3-hour limit plus a weekly limit, shown as percentages. Research counts only what it actually uses, and you can always start research while you have usage left; if you run out mid-way, it stops and keeps what it found.

FAQ
Questions before you start
How is this different from asking a chatbot?
A chatbot answers from memory and can make things up. Acastus Intelligence reads real sources for every question and only keeps facts it can match to the original text. Each statement in the report links to the excerpt it came from.
What happens when I run out of usage?
You can start research whenever you have any usage left. If you run out while it runs, it stops and writes the report from what it already found. Usage frees up as the 3-hour window rolls on, and the weekly limit resets every Monday.
Do I need a subscription?
No. The Free plan has every effort level. Plus, Pro and Ultra give more usage and more at once; cancel any time and the account returns to Free.
Does my Astrix Ultimate or MEGA key unlock it?
No. Acastus Intelligence has its own keys (they start with ASTRIX-INT). Other Astrix keys don't unlock it, and Intelligence keys don't unlock other Astrix apps.
Can it be wrong?
Sources can be wrong or out of date, and the report tells you how strongly each fact is backed: how many independent sources agree, and where they conflict. Anything it couldn't verify is listed, not hidden.
Where do my reports live?
Research runs on the Acastus research server and your reports are stored with your account. You can export them, or export all of your data from Settings.
