Harper is cur­rently un­der­go­ing some pretty rad­i­cal changes when it comes to its lan­guage analy­sis. These im­prove­ments will im­prove the out­put of our ex­ist­ing rule en­gine, in ad­di­tion to mak­ing en­tirely new cor­rec­tions pos­si­ble.

After re­ceiv­ing some feed­back re­lated to the sug­ges­tion box’s vi­sual un­pleas­ant­ness and dif­fi­culty to un­der­stand in­tu­itively, I’ve started mak­ing some mod­i­fi­ca­tions. Nothing dras­tic—I don’t want to con­fuse ex­ist­ing users.

SpellBolt is a Firefox ex­ten­sion that de­liv­ers Harper’s fan­tas­tic gram­mar check­ing straight into your Firefox browser.

There are a great va­ri­ety text ed­i­tors on the web, each used in a dif­fer­ent con­text. That’s a beau­ti­ful thing, but un­for­tu­nately our users ex­pect Harper to work in all of these places seam­lessly.

If there is one thing o3 is use­ful for, it’s find­ing canon­i­cal doc­u­men­ta­tion for com­plex sub­jects.

When our users in­stall Harper, they should ex­pect it to work any­where they do.

Where did Harper come from?

How I pre­view my Markdown quickly and re­li­ably.

It’s eas­ier than you think.

How I in­tend to live bet­ter.

It al­most feels wrong. Maybe it is.

Back in my day, we used math for au­to­com­plete.

How I built a soft­ware ren­der en­gine from scratch, and you can too.

It saved me enough time, I had some to share about it.

It did­n’t work for me, and if you read­ing this, it prob­a­bly won’t work for you ei­ther.
