DataBridge
Email cleaning that shows its work
What it does
Email cleaners always felt like a black box. Upload a list, get a number back, no idea what got tossed or why. DataBridge runs 8 validators on every address - syntax, MX, typos, role accounts, disposables, duplicates, no-reply, risky TLDs. Each rejection tells you why. Plus auto-repair: gmial.com becomes gmail.com in one click, instead of just being deleted. Saves 3-8% of typical lists. Solo founder, 8 months in. Free: 1,000 rows/month, no card. Pro: $29/mo for 100k rows.

- MFmailtrim – find what's actually filling your Gmail inboxApr 2026 · ▲34
I always assumed Gmail bloat came from large attachments. Turns out 3 senders were responsible for 30% of my inbox — thousands of tiny emails I'd never thought to clean up. I built mailtrim to surface this pattern: - ranks senders by actual storage impact (not just count) - confidence scoring on what's safe to bulk-delete - 30-day undo on everything — nothing is permanent by default - runs entirely locally, no email data leaves your machine Free, open source (MIT). No subscription, no backend. One friction point upfront: Gmail API setup is one-time, ~15 min. After that it's just `mailtrim…

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
