A moderate opportunity with a large addressable market but severe competition, low retention potential, and unproven willingness to pay.
Founder verdict
MAYBE
Filtered identifies a real annoyance in the AI‑slop era, but without deeper integrations, a data moat, or enterprise‑grade proof, it’s a feature, not a standalone business for most founders.
What is Filtered?
Filtered is a Chrome extension that scores drafted messages in Gmail, Slack, LinkedIn, Outlook, and Notion for clarity, quality, and voice. It delivers a single actionable fix before sending, targeting the gap between generating AI text and sending effective communication. With a freemium pricing model and a forthcoming team plan featuring aggregated analytics, Filtered positions itself as a lightweight layer against the rise of sloppy AI-generated workplace messages. Its punchy copywriting and precise UX hint at a product built for immediate utility, though public traction evidence is absent.
