Fornax

Fornax is a tool for early-stage startups that want a read on their pitch deck before it reaches a real investor. You upload the deck and the tool goes through it page by page, then returns suggestions. The feedback covers three areas: how the product and slides look, how the team comes across, and whether the market fit is clear. The point is that the advice is actionable, so you can revise specific slides rather than rewriting the whole thing. A free trial is available, and the page says it works without registration, which lowers the barrier to trying it.

- Get a page-by-page read on a deck you have already built.

- Find slides that are weak on design or unclear on message.

- Check whether the team and market story lands.

- Revise and re-check before a real investor meeting.

- Founders preparing for a fundraise.

- Startups without an advisor network to review decks.

- Anyone presenting to investors for the first time.

AI feedback is a second read, not an investor. It will not tell you whether the market actually wants your product, and it can be confidently wrong about a slide. Uploading a deck also means handing confidential material to a third party, which matters if you are pre-launch and have not shared it widely. The site returned an error when checked, so availability may be unstable, and trial limits are not described. Verify both before you build a process around it. Name and archive exported files consistently so you can find and reuse them, and keep a backup copy of key data.
