Get it done, then get on with it.
Every tool here takes one everyday task and finishes it properly: a good-looking email, a copy of an AI chat you can actually trust, and more on the way. No account to make, nothing to learn, and nothing that phones home.
The same promise on every tool
- No account. Nothing here asks you to sign up to try it.
- No tracking. No analytics, no telemetry, no third party scripts, on the tools or on this site.
- Your data stays yours. There is no heyyoshi server and nothing is collected. What a tool sends to do its job, like an email from your own Gmail, goes to that service and never to us.
- The price is on the page. Most of it is free. Where something costs money, it says so before you install it, not after.
Each one takes a specific job off your plate and does it right. Here is what is ready to use now, and what is being built next. Nothing on this list is a mockup: an entry appears once there is something true to say about it.
Mailplate sends a personalised message to each of your customers, members or contacts, from your own Gmail. There is no account and no server: your list never leaves your browser, and the only sending limit is Gmail's own.
The context management layer for claude.ai Projects. Maintain centralized Shared Library groups, sync reference docs across projects in one click, duplicate projects to test prompt variants safely, edit context files in place, and back up your entire Claude workspace locally.
Keep a complete, trustworthy copy of any ChatGPT or Claude conversation: the answers, the reasoning, the searches it ran, and the files you gave it. Every export ends by telling you exactly what made it in and what could not be reached, so you are never relying on a file that quietly dropped something.
One job, done properly
Each tool picks a single task you would rather not do by hand and finishes it well. No suite to buy into, no dashboard to learn, nothing bolted on that you did not ask for.
Working in a minute
No account, no sign-up, no trial to start. You install it or open it and it does the thing. The browser tools run on your own machine and keep your work there.
It gets out of the way
Once it has done its job it stops asking for your attention. Nothing nags, nothing upsells, and nothing you have installed will start charging later.
Free where it can be, paid where it has to be
Most of what is here costs nothing, because most of it runs entirely inside your own browser and so costs nothing to run. Those tools stay free, and nothing you have already installed will start asking for money.
Some things cannot work that way. A tool that needs a server, or that took months rather than days, may carry a price. When it does, the price is on its page before you install it, and it is stated plainly rather than hidden behind a trial. That is the whole of the commitment: not that everything is free, but that you always know which it is.
More is on the way
New tools land here as they are ready, each one taking another everyday task off your plate. Start with what is here, and check back for the rest.
