1. Replace a $399/mo tool with your own bot for about $45

A founder had Grok Bot scan Gmail invoices for subscriptions it could rebuild. It built an AI-visibility bot to replace a $399/mo SEO tool; with lots of feedback it reached about 80% of the quality for about $45/mo.

2. Have your bot vet a too-good-to-be-true collab email before the call

A developer had booked a call with a 'Japanese web dev' who found them on GitHub. Grok Bot noticed the name didn't match the email and matched the identity-leasing scam pattern, pulling 10 real cases plus FBI/DOJ reports.

3. Let your agent haggle with a store's support bot for a better price

A user's ChatGPT Dot joined a company's customer-service chat, introduced itself as their agent and negotiated a lower price. The store's bot negotiated back, then both bots asked their humans to confirm.

4. Cut a 118-second raw take to 59.5 seconds automatically

A creator built an open-source pipeline where Claude Code picks the cuts from a local Whisper transcript and ffmpeg renders them. 42% of the first raw take was pauses and retakes, so it came out at half the length.

5. Turn a single-player game into co-op with your friends

Co-op Anything is an open-source playbook and MCP server: point your coding agent at a game and it researches existing mods, reverse engineers what it must, tests with in-game bots and packages a one-click install.

Have your bot vet a too-good-to-be-true collab email before the call

Before I take any call with someone new who cold-emailed me, check them out: does the sender name match the email address and domain, do they mention anything specific about my actual work, and does the pitch match any known scam playbook (fake recruiters, 'long-term collaboration', identity-leasing)? Find real public reports of similar scams. Give me a red/yellow/green verdict with reasons, and draft a polite cancel message for me to approve if it's red.
